Once again, Hashem Paskening something is different than a historical proof as to what the Sanhedrin Hagadol Paskened. Eilu V’eilu applies to Hashem too. Even though He has His P’sak He gave us the Reshus to overrule Him because of Lo Bashamayim Hi. We don’t have the Reshus to overrule the Sanhedrin Hagadol and Chazal. If we could know, with certainty, what they Paskened then we would have to follow them.
