Review משנה דף כב and the Gemara until א”ר יצחק (bottom of the Amud)
Clarify when we say אתי רבים ומבטלי מחיצות
Major Question:
The gemara asks a question on the Rabanan How could they allow a לחי וקורה on one side and צוה”פ on the other when Yerushalayim needed it’s gates closed in order to prevent it from being a Reshus Harabim.
How could the gemara ask on the Rabanan a question based on the requirements of Rebbe Yochanan. They clearly have different requirements. As the Rabanan hold if there are four corners it’s considered a Reshus Hayachid and we don’t say אתי רבים ומבטלי מחיצות?
There is a major dispute in the Rishonim how to answer this question
