Question in learning

Hello L. I'm glad to hear you're teaching. Good luck. Regarding your question, I do not see a necessary connection between the question of permission-rejection and innovation, and all you have in it is innovation. In my opinion, permission and rejection can both be innovation or not. Regarding the Gazia, and all you have in it is its renewal, I wrote in my article about conspiring witnesses. Is it known? It's on my website (search for conspiracy witnesses or the decree of the scripture). Regarding permission and rejection, two comments: 1. The Rishonim already bring a nefm to the scope of the permit (in the context of picun and Shabbat). The ND does not have a nefm to the scope of the permit, because even if they believe that it is permitted, the permit is only when it is needed for the purpose of picun. Therefore, there is no real nefm here (i.e., it is possible to have a limited permit and a broad dehoya). Therefore, it is necessary to discuss what the Rishonim meant by the terms permitted and dehoya. 2. Regarding impurity, I once thought it was unclear why impurity was permitted in public. After all, the virtue of the public can reject impurity. But how is it overcome? And it occurred to me that the public does not die (only its details change. See the beginning of "On the Repentance" and more), and therefore impurity does not belong in it. I also linked this to the rule of doubting impurity in the Rabbinical Law – clean and the Rabbinical Law – impure.
