With God's help

When a dispute breaks out among the judges in a religious court, the rule is follow the majority. The opinion of the majority of judges determines the ruling. I have previously argued that, on a straightforward reading, the purpose of the majority in a religious court is to clarify the factual and legal truth,[1] as Sefer HaChinukh writes in commandment 78:

And the choice of this majority, it would seem, applies when the two opposing camps are equally versed in the wisdom of Torah; for one cannot say that a small group of sages should outweigh a large group of ignoramuses, even if they were as numerous as those who left Egypt. But when wisdom is equal, or nearly so, the Torah informs us that a greater number of opinions will always agree with the truth more than a smaller number. And whether they in fact agree with the truth or not, in the view of the listener, the law requires that we not depart from the path of the majority. What I mean in saying that the choice of the majority always applies when the two disputing camps are equal in knowledge of the truth is that this is so everywhere except in the Sanhedrin. With them, we do not scrutinize, when they disagree, which side knows more; rather, we always act in accordance with the majority among them. The reason is that their number was mandated by the Torah, and it is as though the Torah explicitly commanded: after the majority of these, you shall conduct all your affairs. In addition, they were all great sages.

He assumes that the purpose of the majority is to come as close as possible to the truth, and therefore when there is a dispute between a small number of sages and a larger number who are less wise, it is the majority of wisdom that determines the ruling, not the majority of persons. To be sure, the decisors are divided on this issue, but it seems to me that virtually all commentators, including those who disagree with Sefer HaChinukh on this point, agree that the purpose of a majority in a religious court is to come as close as possible to the truth. This is unlike a democratic majority, whose function is to constitute the "truth" rather than uncover some objective truth.[2] It is precisely this point of departure that raises what is called the doctrinal paradox, which I want to discuss here.

Background: Following the Majority for Different Rationales

I will begin with the question of what the rule is when the opinions in the religious court are based on different rationales. The same applies to rulings about what is forbidden and permitted, where it is accepted in Jewish law (see Shulchan Arukh, Choshen Mishpat 25:2 and below) that one follows the majority of opinions among the halakhic decisors. What is the rule when the various decisors issue the same ruling, but on the basis of different rationales?

Rema, Choshen Mishpat 28:2, writes in the name of Maharik:

Likewise, if there is one individual against the majority, we follow the majority in every place (Rashba, siman 203/253), even if the majority do not agree for the same reason, but each has his own independent reason; since they agree regarding the legal ruling, they are called a majority, and we follow them (Maharik, shoresh 41/94).

The Shakh there, in subsection 19, qualifies this:

And even if the majority do not agree for the same reason, etc. In my work Siftei Kohen on Yoreh De'ah, siman 242 [in the rules of prohibition and permission], I argued that in a Torah-level prohibition we do not follow the majority if they agree to be lenient on the basis of two different reasons; see there. However, it appears that this applies specifically when we come to permit a ruling that is doubtful to us on the basis of the halakhic works. Therefore, since the majority are not before us, we are concerned that on this fundamental point the law may follow the decisor who is stringent, while on the other point the law may follow the second decisor who is stringent. But when the majority are before us, it is obvious that we follow them even though they do not agree for the same reason, for nowhere do we find that the Sanhedrin or judges need the majority to state one single reason. This also seems implied in the chapter "Echad Dinei Mamonot" [34a], where it says: Come and hear: the two court scribes write the words of those who acquit and the words of those who convict. Granted, the words of those who convict, etc.; but why the words of those who acquit? Is it not because if they later see another reason to convict, we do not pay attention to it? No; rather, so that two people should not state one reason from two verses, as Rabbi Assi asked Rabbi Yohanan: If two state one reason from two verses, what is the law? He said to him: they are counted only as one. From where is this derived? Abaye said: for Scripture says [Psalms 62:12], "God has spoken once; twice have I heard this"—one verse may yield several reasons, but one reason does not derive from several verses. This shows that if they stated two reasons, in any event we follow them, for otherwise it should have answered: No, so that two should not state two different reasons. Moreover, Abaye says that one verse may yield several reasons, etc. And the reason we do not say that two may state one reason from two verses is, as Rashi explained there [s.v. "they are not counted"], because certainly one of these verses was not said for this purpose, since we maintain that two verses are not written for one reason; therefore one of them is definitely mistaken. End quote. [Afterward I saw that in Hagahot Ashiri to the chapter "Echad Dinei Mamonot" [sec. 5] he also explicitly wrote as I did, and this is his language: Three who sat in judgment, and two acquit and one convicts, or two convict and one acquits—and indeed the two disagree with one another, so that this one's proof is not at all acceptable to his colleague, and likewise that one's to his colleague—it seems to me that since the two are equal in acquittal or in liability, they constitute a majority; and he wrote out a proof at length. From Or Zaru'a. End quote. Perhaps he intended the proof that I wrote.][3]

Even if there is room for debate regarding rulings about what is forbidden and permitted, with respect to a religious court whose judges sit together and deliberate, the matter is entirely agreed upon: the majority is determined by the bottom lines, not by the rationales.[4]

The Basic Difficulty: Rationales or Bottom Lines?

The conception I presented above, according to which the purpose of majority rule in a religious court is to come closer to the truth, raises a major difficulty with regard to the rule described here—that one follows the majority even when it rests on different rationales. Consider, for example, 23 judges sitting in a capital case, of whom 15 convict and 8 acquit. But each of the 15 judges who convict bases his view on a different rationale from the others. For example, each claims that the defendant's act falls under a different category of prohibited Sabbath labor (and let us assume, for purposes of the discussion, that he was warned with respect to all of them, or that no separate formal warning is needed for each labor): one judge sentences him to death because he engaged in sorting, the second because he kneaded, the third because he trapped, and so on. The dispute concerns the same act, of course, and the judges disagree over which prohibited labor is transgressed by performing it. As we saw, the ruling in such a case is that the defendant is executed by stoning as a Sabbath desecrator, because there is a sufficient majority among the judges for that.

But when we look at the level of the rationales, this is far from simple. Seemingly, against each of the rationales offered by those who convict, there is an overwhelming majority—22 judges who reject it. Twenty-two judges think he did not sort, 22 think he did not trap, 22 think he did not knead, and so on. Moreover, all eight judges who acquit agree that none of the rationales for conviction is valid. That means that the best-supported view is actually the minority view, namely, the view that the defendant committed no offense at all. If so, when we examine the rationales for the death sentence one by one, the conclusion is that none of them is correct (assuming that the majority is the criterion of truth). So how can one execute a person in such a situation?

If the purpose of the discussion is indeed to uncover the truth (and not to constitute it, as with a democratic majority), then it is only natural to expect that a majority based on different rationales would not count as a majority. If we are searching for the truth, we ought to follow the rationales and derive the conclusion from them, not seek a conclusion detached from rationales. The relevant question is whether that person trapped or did not, sorted or did not. Why does it matter that, according to a majority of opinions, he is liable to death, when each judge convicts him for a different reason? From the standpoint of the truth regarding the rational basis of the ruling, he is apparently not liable to death. And yet Jewish law accepts the majority ruling in such a case. The question is why.

Distinguishing Between Different Types of Dispute

In the past (see my article "Is Jewish Law Pluralistic" and the article on "The Price of Tolerance"), I pointed out that in most disputes among sages both sides are correct at the level of the rationales. I likened this to a dispute over whether to eat chocolate, where Reuven says one should because it is tasty, while Shimon says one should not because it is fattening. Both sides raise correct rationales, because there is no dispute that chocolate is both tasty and fattening. The disagreement concerns only the relative weight of the rationales: should considerations of taste (pleasure) take precedence over considerations of health (fattening), or vice versa? If the dispute in the religious court is of this type, it would seem that the difficulty I raised collapses. None of the judges disputes the other's rationale; they merely weigh them differently. The difficulty described above was based on the fact that the rationales raised by the judges are themselves disputed—that one judge does not agree with another at the level of the rationales.[5] To be sure, even in a dispute of the type described here there may still be room to see a difficulty. After all, at the bottom line one judge disagrees with another about the ruling or the punishment, even if the disagreement concerns only the relative weight of the rationales. This depends, of course, on further details, and I will not enter into that here.

In other cases, the core of the dispute is whether the act that was done crosses the Torah-level threshold or not.[6] Thus, for example, a decisor or a judge may think that the act performed does resemble sorting in a certain respect, but does not cross the Torah-level threshold (for example, someone who sorted food from waste, or by hand and not with a utensil; or someone who trapped a species not ordinarily trapped). But both agree that there is some element of sorting or trapping here, and that at least on the rabbinic level it should be prohibited. In such a case the difficulty remains in place, for so long as we have not crossed the Torah-level threshold there is no liability to punishment. Therefore, in such a case the dispute about the punishment or the ruling is genuine, and the difficulty I described can still arise.

A third case is where one judge thinks there is some chance that the other is right, but in the bottom line rules that he is not. In this kind of dispute, the difference is not one of substantive threshold, as in the previous type, but of the probability that the other is right. That is, the dispute is not over how much of the labor of sorting is present here, but over what the probability is that this is indeed the labor of sorting. In this case, the chances that the second judge is right are greater, because even the one who disagrees with him grants him a certain probability. In disputes of this type it is highly doubtful whether the difficulty I described exists at all (here too, of course, this may depend on how much probability each judge assigns to his colleague's rationale).

For our purposes here, this brief description will suffice.

The Doctrinal Paradox

There is an extreme case in which the difficulty I described is very easy to see, and it is called the doctrinal paradox. Consider a case in which two litigants who signed a contract come before the religious court. Shimon claims that Reuven breached the contract and sues him for payment, while Reuven claims he did not. In order to decide whether Reuven is liable to pay, the court must discuss two questions: 1. An interpretive/legal question—did the contract indeed forbid Reuven to do X? 2. A factual question—did Reuven do X? Since the two questions are independent, the distribution of opinions can be as in the following table:[7]

Interpretive question Factual question Final ruling
A 1 1 1
B 0 1 0
C 1 0 0

If we analyze these opinions, we get a paradoxical result: a majority of the judges hold that Reuven is not liable (the final-ruling column in the table), and therefore the ruling issued by the court is that Reuven is not liable. But if we examine the opinion of the majority of judges on the interpretive question, we find that, according to the majority, the contract does indeed forbid doing X. On the factual question, we find that a majority of the judges think Reuven did X. If so, seemingly we should have ruled that Reuven breached the contract and is liable to pay. That is the ruling that emerges from analyzing the rationales and reasons, and it is of course contrary to the judgment that expresses the majority opinion at the bottom line. In other words, had we followed the rationales, the ruling would have been that Reuven is liable to pay, but in practice the ruling is that he is exempt.

The Doctrinal Paradox: A Real-Life Example

You probably think this is a case that I "tailored" (not I, of course; it is a well-known paradox) only in order to create a paradox—that is, a hypothetical situation that never actually occurs. To that I would say that I see no reason why there should not be masses of such cases involving contracts, or parallel situations in other legal contexts as well. I am sure there are quite a few such cases. A few months ago I myself encountered such a case, when I read a Supreme Court judgment dealing with the abduction of a girl by her mother. The case went through two judicial instances[8] and in the end the Supreme Court ruled that the girl would remain with her mother. The distribution of opinions in the Supreme Court was exactly as in the table above.

To understand this, I should preface that child abduction (by parents) is adjudicated under the Hague Convention (for the welfare of the child). Under the rules of the Convention, even if we conclude that there was indeed an abduction, if the other parent consented (at the time of the abduction, and only now is suing because he has regretted it) or acquiesced (retroactively, at some point after the abduction), there is no duty to return the child to the shared custodial arrangement. The views of the Supreme Court justices were as follows: all agreed that there had been an act of abduction and that the Convention's rules applied. But one of them held that there had been neither consent nor acquiescence. A second held that there had been acquiescence but not consent, while the third held that there had been consent but not acquiescence. As stated, the distribution of opinions was exactly as in the table above, and therefore it was decided by majority view that the girl should not be returned. But when we examine the question at the level of the rationales, with respect to whether there was consent, the majority view is that there was not; and the same is true regarding acquiescence. If so, this is a case of abduction without acquiescence and without consent—and seemingly the law should have required that the girl be returned to her father's custody.

Interim Conclusion: The Ruling Is the Bottom Line

The picture that emerges from here is that the opinions of a judge or justice, both in the realm of Jewish law and in the realm of secular law, are the bottom lines and not the rationales. Therefore, when opinions are counted and a majority is formed, what is counted is bottom lines, not rationales.

Perhaps one can see such an approach in a fairly widespread halakhic phenomenon, in which medieval authorities (Rishonim) rule in a dispute among Amoraim (Talmudic sages), or an Amora rules in a dispute among Tannaim (Mishnaic sages), and the ruling decides like one of the disputants in one case and like the other in another case. Seemingly, such a ruling contradicts both views, and if one assumes that an Amora cannot dispute with Tannaim or that a medieval authority cannot dispute with Amoraim, this should be impossible.

Let us take as an example the dispute between the Tannaim in Mishnah Ketubot 12b:

If one marries a woman and does not find signs of virginity, and she says, "After you betrothed me I was raped, and your field has been flooded," while he says, "No; rather, it happened before I betrothed you, and my transaction was a mistaken transaction"—Rabban Gamliel and Rabbi Eliezer say: she is believed. Rabbi Yehoshua says: we do not live by her word; rather, she retains the presumption of having had intercourse before she became betrothed and of having deceived him, unless she brings proof for her claim.

The Talmud there explains that the husband is making an uncertain claim (because he does not know exactly what happened to the woman), and according to Rabban Gamliel the woman is believed. Rabbi Yehoshua disagrees and maintains that she is not believed, because a definite claim against an uncertain claim cannot extract from the party in possession. The Talmud there presents a dispute among the Amoraim over whether a definite claim can extract from one in possession who advances only an uncertain claim, and the law is ruled in accordance with Rav Nahman, who holds that it cannot. In the course of the next passage in the Talmud (13a, before the Mishnah there), it becomes clear that Rabban Gamliel holds that the woman is believed in every case, while Rabbi Yehoshua holds that she is not believed in any case. But Rav Nahman rules (and so all the decisors ruled) like Rabban Gamliel when the woman has a migo (the ability to have advanced a stronger claim)[9] and like Rabbi Yehoshua when she does not have a migo.

Seemingly, Jewish law here was ruled against both Tannaitic views: it accords neither with Rabban Gamliel (who holds that a definite claim against an uncertain one can extract even without a migo) nor with Rabbi Yehoshua (who holds that a definite claim against an uncertain one cannot extract even if she has a migo). How can an Amora rule against both Tannaitic views, not in accordance with anyone ("like no one")? Necessarily, such a ruling is possible because each of the Amora's rulings is anchored in a Tannaitic view. The ruling that without a migo she is not believed is anchored in Rabbi Yehoshua, and the ruling that with a migo she is believed is anchored in Rabban Gamliel. To be sure, this is not in accordance with their rationales; that is, at the level of the rationales, the ruling contradicts the opinion of both Tannaim. And yet the bottom line does not contradict the views of all the Tannaim, and therefore this ruling is legitimate. Once again, we can see here that what binds us is the bottom line of the Tannaim, not their rationales.[10]

A Technical Explanation

And yet this phenomenon still requires explanation. If our aim is to rule in accordance with the truth, we ought to decide according to the rationales and not according to the bottom lines.

It seems there is no avoiding an explanation in terms of technical considerations. The rule that the majority at the level of the bottom line is determinative is certainly the simplest and most efficient way. One must remember that it is not always clear what exactly the dispute over the rationales is, or whether there even is one. Every judge would have to express his view about every rationale of his colleague, and then we would have to perform a probabilistic balancing and total up the support of all the judges for every rationale in order to reach a ruling. I remind you that I presented above three different types of dispute, and in each of them the aggregation of opinions at the level of rationales would have to be done differently. Once rationales and reasons are taken into account, the way to calculate what the ruling is becomes complicated and ill-defined, and perhaps that alone is enough to explain why Jewish law and secular law follow a majority of bottom lines. If so, it seems that the reason one nonetheless follows the bottom line and not the rationales is probably legal efficiency.

But in one of the lectures I gave on the subject, one of the listeners (my friend Shmuel Keren, to whom I am grateful) raised another possibility, a probabilistic one. He argued that perhaps precisely if we follow the majority of opinions at the level of the bottom line and not the rationales, this maximizes the likelihood that the ruling will be correct. I told him that this was an interesting proposal, and that I would check it. Here are the results of that examination.

A Probabilistic Calculation: Assumptions and Framework for the Discussion

In column 145 I presented calculations showing why the rule follow the majority, which establishes that in a case of dispute one follows the majority of judges, really does bring us closer to the truth. There I calculated the probability that the ruling hits the truth (= the quality of the ruling) on the basis of reasonable assumptions about the quality of the judges (the probability that each of them hits the truth), and I showed that with skilled judges the majority indeed gives the result closer to the truth. Here I will present a similar calculation concerning the doctrinal paradox presented above, and examine whether a decision according to the bottom lines is indeed less reliable (that is, less likely to hit the truth) than a decision in light of the rationales. I will do so, of course, under reasonable but as simple as possible assumptions, and with as simple a case as possible. Even so, the results are quite surprising.

As there, so here, let us assume that the quality of a judge is expressed in the probability that he hits the truth, whether factual or legal. That is, the conditional probability that if the truth is X, the judge will rule X. There I denoted the quality of the judge by the letter P. In our case, the relevant probability is of course the probability that the judge's rationale (I do not distinguish here between a legal rationale and a factual one) is correct, not that his bottom line is correct (as I assumed there).

In probabilistic terms, we will say that the quality of the judge is determined by the probability that if the true rationale is X, he will indeed determine that X (again, for the sake of simplicity I do not distinguish between a legal determination and a factual one). For our purposes, we will assume that all the judges who sat on the case and whose opinions are displayed in the table above have quality P. The meaning of this is that on the interpretive-legal plane, if the contract forbids the act in question, then with respect to each of the judges there is a probability P that he will say that the contract indeed forbids it. And likewise on the factual plane, if Reuven did in fact do X, the probability that each judge will determine that he did X is P.

It should be remembered that the quality of an arbitrary decision is 0.5, because even if we were to choose at random an answer to such a binary question (he did it or did not do it, the contract obligates or does not obligate), we would get the right answer with probability 0.5. Therefore, we will assume that the quality of the judges, that is, the probability P, is higher than 0.5. Otherwise we are not dealing with a skilled judge but with mere random lottery.

Now we look at the table before us and see what the judges said. The question before us is whether Reuven breached the contract or not. The determinations regarding the rationales (the interpretive and the factual) are only an instrument and have no importance in themselves. Therefore we must examine, given that these are all the data about the judges' views on the two questions, what the probability is that Reuven actually breached the contract. If that probability is higher than 0.5, then one should follow the bottom line. If the probability is lower than 0.5, then one should follow the rationales.

How can it even be that in such a situation it is preferable to follow the bottom line? Seemingly, the bottom line is nothing but the result of the rationales. Given the truth about the rationales, the final truth is derived from them in an unambiguous way. When we present the problem in this way, one can see that even if, with respect to each question separately, the majority is more likely to be right, there is still also the possibility that it is wrong about that question. And that possibility can combine with the possibility that the majority is wrong about the second question and together create a situation in which Reuven still did not breach the contract. In this way, it can in principle happen that it is precisely the bottom line that brings us closer to the truth.

At this point it is easy to guess that even if we discover that the bottom line really can bring us closer to the truth, this result will probably not be universal. It depends on the distribution of opinions, on the value of P (= the quality of the judges), on the question whether all the judges have the same quality, on how many different rationales there are and what the distribution of opinions regarding them is, and more. This can of course also depend on the nature of the disputes that arose in the religious court (as we saw in the three types described above). But here our concern is only demonstration, and therefore I will make do with analyzing the case in the table and with the simplest assumptions.

The Calculation

We must calculate the probability that Reuven did in fact breach the contract. We saw that this event is a conjunction of two claims: that the contract forbids doing X and that Reuven did X. I will assume here that these are independent events,[11] and therefore the probability of this is the product of the probabilities. Now note that the calculation with respect to each question separately is identical to the calculation we made in column 145 (what is the probability that the majority is right on some legal question, given the quality of each judge). There we found that in a case where three judges are divided (two against one), if these are skilled judges then the two are more likely to be right (that is, the probability Q of this is above 0.5). Given that we have a product of two such numbers, the answer becomes obvious. The probability that the majority is right with respect to the factual question is Q, and so too the probability regarding the interpretive question (it is the same calculation, and our simplifying assumption is that the skill of the judges is identical with respect to legal questions and factual questions).

Hence the probability that Reuven breached the contract in our case is Q2. The question whether this quantity is greater than 0.5 receives a simple answer. As noted, it is only reasonable to assume that Q>0.5, for there we reached the conclusion that the majority is more likely to be right. And from this it follows that, if indeed we are dealing with a panel that reaches the correct decision on a single question with probability greater than 0.7, then Q2>0.5.

I remind the reader that the result we obtained at the end of column 145 was that under simple assumptions (for example, that the a priori probability of the two answers to the question is equal, and that all the judges are of the same quality) the probability that the majority is right is exactly Q=P; that is, the probability that the majority is right is exactly equal to the skill of the individual judge. Hence, under the assumption that these are judges whose skill is significantly above the baseline level (the random draw—P=0.5), namely judges whose skill is above 0.7, the legal result in the doctrinal paradox is that one should follow the rationales (that is, rule that he breached the contract) and not the bottom line (which leads to the conclusion that he did not breach the contract). With very skilled judges one should decide according to the rationales, but in the case of less skilled judges it is better to follow the bottom line.

The resulting picture is as follows:

If P is between 0.5 and 0.707 – one should follow the bottom line.

If P is between 0.707 and 1 – one should follow the rationales.

In other words, if the judges are not highly skilled, there is no paradox here: deciding according to the bottom line is also the decision that brings us closer to the truth. But with very skilled judges (significantly above the baseline level) there it is indeed preferable to follow the rationales.

In Practice

So what should we do now? Follow the bottom line or the rationales? Can such a calculation justify following the bottom line? To answer that, we must ask ourselves: if we want to establish a sweeping rule, what is the more sensible thing to do?

It seems to me that there is logic in establishing a sweeping rule that one follows the majority with respect to the bottom line. To be sure, this is not always correct (with very skilled judges it is not optimal), but as we saw above, in order to avoid complexity and achieve efficiency one needs a uniform decision for all cases and all types of panels. Since we have seen that a decision according to the bottom line is not as absurd as it appears at first glance, and that it is not even necessarily worse than a decision according to the rationales, legal reasoning says that one should establish a sweeping rule that always instructs us to act accordingly. The technical consideration I presented above now receives a probabilistic anchor and reinforcement. There remains a technical dimension in adopting such a rule (because factually it does not always bring us to the best decision), but now it is called for and reasonable, no less—and perhaps more—than the determination to follow the rationales. And as for the perfect judges, my apologies…[12]

[1] See my discussion of this in columns 66, 69, and 79.

[2] See the aforementioned columns.

[3] Regarding the Sanhedrin 34 passage from which he brings proof, see my article in Midah Tovah, 5766, at the end of Parashat Shemot (here, article 67).

[4] Although, as noted, there is also a dispute among the decisors even regarding a religious court, whether what determines the matter is the quantitative majority or the qualitative one.

[5] And that is apparently also the case when the sources they adduce in support of their words are different (as in the aforementioned Sanhedrin 34 passage).

[6] See a fuller discussion of this in our book On Fuzzy Logic in the Talmud, the twelfth in the Talmudic Logic series, and in Daniel Weil's article in issue 1 of the journal Higayon.

[7] A 1 means an affirmative answer to the interpretive/factual question (the contract forbids / the act was done). A 1 in the final-ruling column means that Reuven is liable to pay.

[8] See here and the legal opinion of the State Attorney's office here.

[9] She claims that she was raped after betrothal (and that does entitle her to a full ketubbah payment but disqualifies her from marrying a priest), but she could have claimed that she had lost her virginity accidentally (which also would not have disqualified her from marrying a priest). That is a better claim, and therefore she has a migo.

[10] Here is this principle in the form of a rule (Yad Malakhi, "Rules of the Talmud," sec. 40):

An amora has the authority to effect a compromise between the tanna'im, and this is not considered as ruling neither like this master nor like that master; and we indeed find this in several places, among them in the chapter "Ra'uhu Beit Din" and at the beginning of the chapter "Cheresh," in Mayim Chayim to Pri Chadash, fol. 32a; and he likewise wrote this in the laws of Passover, siman 442, se'if katan 1:

See also Gufei Halakhot 38; Halikhot Eli 519; and others.

[11] This is not precise, because on a straightforward view there seems to be dependence between them: assuming that the contract forbids the act X, it is reasonable to assume that Reuven would not do it. In any event, the probability that he did it is not equivalent to the probability that he did not. To be sure, Shimon too enjoys a presumption of integrity, and therefore the probability that he is lying should also be small. In practice this is of course complicated, and therefore once again we will assume simplifying assumptions here, and for our purposes we will assume that there is no dependence between the questions.

[12] One might perhaps suggest a consideration according to which, if the judges are perfect, it is less likely that such a paradoxical table will arise at all. The disagreements among such judges will be more minor, and presumably we will reach the correct result one way or the other. According to this, from the very fact that we are dealing with a distribution of opinions like the table of the doctrinal paradox, it is reasonable to infer that these are not perfect judges. That further strengthens the decision to follow the bottom line rather than the rationales. With perfect judges it will yield the correct result from both directions (both from the rationales and from the bottom line), and with imperfect judges it will yield the correct result because with them the truth is obtained by the consideration of a majority at the level of the bottom line.

Discussion

Shlomo Zalman (2019-11-28)

Regarding judges, perhaps one can simply say, in the language of the Sefer HaChinukh, that “truth” does not mean clarifying the case and the ruling derived from it. Rather, “truth” is what ruling is decreed upon the person, without entering into the details of the case. And that is the parameter the Torah wanted for the court—not what the truth was, but what the truth is that should be done now. And when there is a majority that rules how to act, there is a majority truth. Of course, all this that we relate to it as truth is only because of their wisdom in Torah, as the Chinukh explicitly notes. So every Torah opinion is a ruling, and in the end we decide according to number. But when the groups are not equal in their wisdom, an inherent qualitative gap is created here, and quantity cannot be mixed in with opinions, since those opinions are less Torah-based. Consequently, they are not of equal weight with the “more” Torah-based opinions. And that is why the Chinukh also continues and says, “whether they agree with the truth or do not agree, according to the view of the listener, the law requires that we not depart from the path of the majority.” Since the concept of truth here is not derived from the reasons but only from the rendering of judgment itself. (Of course, none of this contradicts the very method of ruling, which is done by clarifying the case—that is the tool the Torah gave judges in order to rule. But it is only a tool. What actually obligates the person in law is the very content of the ruling, not the content of the clarification of the case. And the clarification of the case is only a practical means that the Torah showed the judges as an indication. Unlike cases where one incurs death at the hands of Heaven and the like, where the liability is because of his actions and not because of a ruling.) And what he wrote, “that a greater number of opinions will always agree with the truth more than the minority”—“agree” means produce and create the truth. One does not follow what is ‘more correct,’ but quantity. And that is also why, regarding the Sanhedrin, the Chinukh adds that we always follow the majority because they are all great sages. Now, even among great sages you could seemingly also find differences between them as to who will clarify the case and rule better. But the whole point is only that their opinion be Torah-based at a sufficiently high level for it to count as truth (for the Torah determined what truth one should act upon, and thus here the Torah said that this level of knowledge of it is enough to count as knowing how to act), and immediately the parameter of quantity comes into play.

I’m not sure I understood, but in the view of the Chinukh it is hard to say that the truth is whatever is decreed. He writes that the way of the world is that the majority hits upon the truth, which shows that he means the factual and legal truth itself. And even logically, there is no advantage to a qualitative majority in order to know what was decreed.

Shachar (2019-11-28)

I think the rabbi really has to go back to writing more “current-events” posts. A post on psychology, or at least on the meaning—or lack of meaning—of emotion in relation to the religious experience…

Michi (2019-11-28)

The public is voting with its feet 🙂

Daniel (2019-11-28)

According to your analysis, it comes out that even a very skilled judge who obligates on the basis of 10 reasons, all of which are required for liability, should not be trusted. That is, this has nothing at all to do with disagreement between judges.

I tend to understand that a judge too is supposed to make the calculation and realize that if many reasons are required for liability, then he has to be very convinced of his ruling. And indeed, many times decisors combine subsidiary grounds for leniency—that is, they are not sure of any single reason and rely on the combination of reasons.

In short, I think the probability of a judge’s error concerns the bottom line, not the reasons.

Michi (2019-11-29)

You are proposing, in order to defend why such a ruling should nevertheless be accepted, that the probability concerns the bottom line. That makes no sense at all, since the bottom line is not a single decision. The conclusion your argument really points to is your opening sentence: even with a single judge there is a problem in complex decisions.

Daniel (2019-11-29)

If there are many different rulings of a decisor before me and I combine them, you are right.
But if the decisor himself combined them, then he too should understand the consideration that perhaps he is mistaken in one of his rulings, and then he would rule differently. If he does not rule differently, then apparently he is very convinced, so the chance that he is mistaken in that specific case is lower.
Are you claiming that his ruling in such a case is worse than a random ruling that does not take the considerations into account?!

Michi (2019-11-29)

Interesting point. I need to think about it.

Michi (2019-11-29)

Take, for example, the Supreme Court ruling I mentioned. Each of the majority opinions was based on one consideration. The problem arose from combining the opinions of the judges. There, it seems to me your suggestion is not possible.
More precisely: in order to determine that the girl should be returned, you need a combination: there was no consent and no acquiescence. But the opinion of the majority judges was that there was consent or acquiescence. Only the minority opinion was a complex consideration of the sort you described, whereas the majority opinion was not. So according to your approach, it comes out there that there is even more chance that the minority is correct (on the level of the reasons), because if it said to return her, it decided with high certainty on each of the two components in its ruling (as a rule, for the sake of simplicity I did not bring each judge’s degree of certainty in his position into the calculation). If so, your consideration only intensifies the difficulty: now it is even clearer that one should follow the reasons and not the bottom line.
Incidentally, if you ask me about the minority judge’s decision in this case, I would bet that he did not see it as one single decision, but discussed each of the components separately. That also seems to emerge from his reasoning there.

Seidler (2019-12-01)

Why can’t we simply say that when there are many different reasons, this points to many different possible ways of explaining the event? Then when we judge and there are, say, 13 different explanations, 11 of which yield that the person is guilty, there are more explanations leading to guilt than explanations leading to acquittal, and therefore we convict. In my humble opinion, it seems that the rabbi is dealing with the question “How can we know what happened?” (in which case there are many explanations for what happened, and indeed we do not know, and the problem the rabbi raises emerges), rather than with the question “Is the person guilty or innocent?” But in legal discussion it is clear that we are dealing with the second question, not the first.

Michi (2019-12-01)

The problem is that none of those explanations is correct (because there is an overwhelming majority against it). So what does it help that there are many ways to obligate? Only if you arrive at the calculation I proposed can you make your claim.

Seidler (2019-12-01)

But there is also an overwhelming majority opposed to the explanation “nothing happened and therefore the person is exempt” (“nothing happened” = “rather, X happened,” where X = nothing; and everyone else claims a different X), so to rule exempt as well, according to the approach you are presenting, is impossible.
And it is not that those explanations are “incorrect” because there is an overwhelming majority against them. Every explanation is a possible explanation even when there is an overwhelming majority against it; it’s just that we don’t think that matters because we are not dealing with “what happened” but with “what is the law.” Indeed, if we are dealing with the question “what happened,” the problem you raise exists (and your calculation does not solve it, because it does not answer that question at all). But that is not what we are dealing with, and the proof is that in such a case, when there are many different reasons to obligate, we obligate without any specific reason. He did not do any specific X, yet he is still liable, because the probability that he did one of the 11 liable possibilities is greater than the probability that he did one of the 2 exempting possibilities. And I do not understand why, in order to make that claim, I need the calculation you proposed.

Michi (2019-12-01)

“Nothing happened” is not an explanation but the result of negating all the other possibilities. As long as it has not been proven that something happened, then nothing happened. That is true factually, but certainly legally (“the burden of proof is on the claimant”).
Check the calculation I made regarding the Supreme Court ruling; there I directly checked the probability that nothing happened (that is, that there was neither acquiescence nor consent).
In the end, you do not escape the calculation I made. That calculation assumes exactly your claim: that there is a possibility the majority is mistaken, and that too must be taken into account.

muli (2019-12-01)

Regarding the “paradox of judging,” see Noda BiYehuda, Tinyana, siman 3. The substance of it is brought in Pitchei Teshuvah there.

muli (2019-12-01)

According to Rambam (beginning of the laws of Sanhedrin), the minimum threshold for a judge is very high: “fit to teach and render rulings in the entire Torah…” According to this, we really should follow the majority of reasons.

Michi (2019-12-01)

Fit to render rulings in the entire Torah is breadth, not necessarily reliability of the ruling itself. That is very hard to measure (in fact, impossible). Besides, see footnote 12 at the end of the column.

Michi (2019-12-01)

Here are his words:
(7) And even if the majority do not agree for one and the same reason. See the responsum of Noda BiYehuda, Tinyana, Choshen Mishpat, siman 3, where he was asked about a case in which Reuven sued Shimon for one hundred: that is, fifty for damage he caused him, and fifty for expenses he incurred because of him. And when the judges deliberated, they split into three opinions: one judge entirely exempted Shimon; the second judge held Shimon liable for fifty for indirect damage; and the third judge also held Shimon liable for fifty, but not for the same fifty of indirect damage, rather for the fifty of expenses incurred. And each of the three judges stood by his opinion, with no one deciding between them. The rabbi who asked was uncertain whether the ruling should be decided so as to obligate Shimon for fifty, since according to the majority of the three judges’ opinions he is in any event obligated to pay Reuven fifty; or perhaps this should not be counted as two opinions, for one could say the opposite: that on each individual claim there is a majority of opinions acquitting Shimon. And the inclination of the asking rabbi was to exempt, and he wrote that the Rema ruled that even from two reasons it counts as a majority of opinions only when it is one claim, but in our case one can combine a majority of opinions to exempt, for on each claim there is a majority of opinions to exempt. And he, of blessed memory, replied that he did not agree with this, but rather that the ruling should be decided so as to obligate Shimon for fifty, since in any event, according to the majority of opinions, Shimon became liable for fifty. And although this is on the basis of two separate claims, still it is no worse than disjoint testimony later in siman 30, se’if 2 and se’ifim 6 and 7, etc. And although there too, regarding witnesses, if they contradict one another—where each says there was no other loan, or the plaintiff says there was only one loan—they do not combine, and if so here in our case the judges contradict one another and disagree, for one says he is not liable on the claim of indirect damage but only on the expense claim, and the second says the opposite. This is not comparable, for contradiction among witnesses means the testimony is wholly invalid testimony, since one of them is certainly lying; but regarding judges, according to the words of the majority, Shimon is in any event liable for fifty, etc. He elaborates somewhat. And he concludes: from all this it appears to me that in our case, since the judges are before us, and from the words of the two of them it emerges that Shimon became liable for fifty, even though they do not agree in their reasoning as to which claim made him liable—and had these not been two claims in one proceeding, Shimon would certainly have been exempt on each claim considered separately by majority opinion—nevertheless, since the two claims came at once, they have the law of one claim, for Reuven claimed one hundred from Shimon all at once; thus regarding Reuven’s claim it emerged from the majority of opinions that he is liable for fifty. End quote—see there.

Very interesting. One might discuss whether there would be an obligation of an oath here according to Rabbi Chiyya’s first ruling (for he became liable for fifty according to two judges. However, one should discuss the law of “he sued him for wheat and barley, and he admitted to barley,” but this is not the place to go into it at length).

muli (2019-12-01)

Rabbi Chiyya was speaking about witnesses, not judges. Although Rashba and Sefer HaTerumah disagreed regarding “liable for part,” all of that would still apply only when two judges obligate for a specific fifty—that is, for the same reason. For even though regarding the ruling, whether based on these considerations or others, we take their conclusions and not their reasoning, nevertheless there is no knowledge here of a specific fifty in order to obligate an oath.

Shemaya (2019-12-02)

I would like to present the definition of majority in Torah law as I see it.
You proceed from the assumption that the reasons are the main part of the discussion, while the decision is only a result. I would like to suggest that the purpose of the judges is not to interpret the Torah, but to instruct what the law is on the basis of their interpretations. That is, the judges’ concern is with the future and not the past: they are meant to decide whether to put to death or otherwise punish the person standing before them in judgment, and whether to permit or forbid the act in question.
Detailing the reasons is important so that future generations can know the different methods of interpretation, but that is not what the judges are appointed for. The reasons are necessary for the discussion because they are the way the judge understands the law of the Torah. The Torah contains a certain text that contains content; the text can be interpreted in many ways, depending on the person, the generation, and the degree of wisdom. It also does not address every situation that may arise over time.
The Torah is aware of this problem, and therefore gave the sages the ability to speak in its name. The sage-judge is essentially the Torah’s spokesman: he “hears” its messages and passes them on. This “hearing” occurs through the interpretation the judge gives the Torah, and because of this, there can be situations in which the Torah speaks in several conflicting and even contradictory voices.
Conflicting = different reasons for the same instruction; contradictory = different reasons leading to different instructions.
Once we establish that the judges’ role is to convey the Torah’s instructions from here on, then even if each one hears the instruction in a different language, so long as the majority determines that they hear a uniform message, even if each one arrived at that message by a different and distinct route, we are supposed to act in accordance with their ruling and not with the minority that heard a different message, even if the minority all heard it in the same language.
What is this comparable to? To a man who instructed his servants to follow whatever orders he would send them, and if each one heard something different, they must gather and act according to the majority view. Even if he sends the majority a uniform message in other languages, and even if what is called “yes” in language X is interpreted as “no” in language V, this still does not prevent the servants from defining those who received the uniform message as the majority. For their concern is not the study of languages but only receiving instructions.
In principle, this explanation applies only to interpretive disputes and not to factual disagreements. But the truth is that a judge’s view of the data presented before him and his analysis of the facts from it are also rooted in Torah. A dispute over analyzing the facts from the data indicates an interpretive disagreement in the laws of evidence and claims, and this explanation can be applied to those as well.
In my opinion, this explanation can be extended to any legal system, even a secular one. The legislator is the one who wrote the static law, relying on the judges to speak in his name what they hear from it. (What he did not take into account is that the judges would not divide in their outlooks according to their proportion in the general population, but would come from a closed clique, and as a result would develop selective and tendentious hearing inclined toward the side of a minority of the public. But that is another matter…)

Michi (2019-12-02)

That is, of course, the simple explanation. After all, in the column too I explained it in terms of considerations of efficiency. Your suggestion is no different, because simply taking the bottom line is not a sensible policy (except because of considerations of efficiency).

M80 (2019-12-02)

Rabbi Reines wrote:
“The truth is that every conceptual notion has many shades, with aspects this way and that, and much investigation is needed in order to establish the inquiry on a proper basis and align it with the true intent. And since people’s opinions are not equal, therefore if the investigators increase, each one, from the perspective of his intellect, will see some side among the many sides, and each will strive to establish it according to his view. And so that he may have the power to argue in favor of his opinion, he will exert himself to investigate and reflect on the matter, and through all of them all the doubts and all the aspects of the inquiry will be clarified, and the conclusion will emerge clear as the sun. Therefore, unity with respect to an intellectual matter is a means by which the matter becomes clarified and whitened. And the clarification produced by them is due to the natural opposition, or inequality, that exists in human intellects. And the benefit that emerges from the unity of minds is not on the side of apprehension—that many apprehend what the individual did not apprehend—but on the side of clarification, for through union the matter is clarified.”

And Rabbi Shimshon of Sens wrote on the mishnah that is the foundation of halakhah:
“And why are the words of the individual mentioned? That is, since everywhere, where there is an individual and the many, the halakhah follows the many, why are the words of the individual mentioned among the many? So that if a court sees the words of the individual—such as the amoraim who ruled halakhot—and when they see the reasoning of the individual they may rule like him. For if his words had been forgotten, the amoraim could not have openly disagreed with the tannaim, who were greater than they in wisdom and number. And on the basis of this they can rule according to his words, for the Torah has already said, ‘Follow the majority.’ And even though the words of the individual were not accepted at first, and the majority did not agree with him, when another generation comes and its majority agrees with his reasoning, the halakhah will be according to them. For the whole Torah was said to Moses with aspects for impurity and aspects for purity, and they said to him: How long shall we stand over clarification? And he said to them: ‘Follow the majority’—yet both these and those are the words of the living God.”

The way of sages is to know what they say and not say what they do not know. Therefore Rabbi Reines wrote:
“But if the concept is very subtle, so that it is hard to apprehend, unity will not help. This is the intent of the saying: ‘In the ordinary way of the world, a burden that is hard for one is manageable for two; hard for two, manageable for four. But is there perhaps a burden that is hard for six hundred thousand and manageable for one? All Israel stood before Mount Sinai and said: “If we hear more, we shall die” (Deuteronomy 5:22), while Moses heard the very voice of the speech and lived’ (Leviticus Rabbah 1). Since there was here depth of concept and inadequacy of the apprehender, even the union of six hundred thousand did not help. Only Moses, who was on the highest level, was able to apprehend it.”

Daniel (2019-12-02)

Indeed, it seems that you are right.
Maybe one can attack it from another direction: it is not enough to know the judge’s skill level in order to know the probability of error; one also has to know the complexity of the question. From the fact that skilled judges argue over the question, one can see that the probability of error is probably large. For a case of a majority of 2 against 1, I calculated that p = 2/3 gives the highest probability for a result of 2 against 1, and that is less than 0.7. Now one has to solve it for the general case.

Michi (2019-12-02)

Possibly. In general, the model I used assumes quite a few simplistic assumptions, so I do not see much point in making overly precise calculations. This calculation only gives a general direction.

Nimtzeinu Lamedim (2019-12-06)

If halakhah is the bottom line, then we learn that ‘Shatz’—the halakhah follows him everywhere, for the bottom line of all his comments is: ‘With blessings, Shatz’—and who would disagree with that statement? 🙂

With blessings, Shatz
