Barry Epstein asked:
The gemara on 40a says that a woman who delivers by caesarean does not acquire childbirth tumah. R'Shimon disagrees. Who do we rule by and why?

The Kollel replies:
The Tana Kama (Rambam Hilchos Isurei Biah 10:5, Shulchan Aruch Y.D. 194:4), as we usually Pasken like the main opinion of the Mishna versus Rebbi Shimon.
