Reply To: Why Can't Women Get Modern Smicha and Become Rabbis?

“The main one I can think of is when a woman immerses in the mikvah, another woman makes the halachic determination whether or not the immersion was halachically valid. They also make halachic determinations regarding chatzitos before immersion as well.”

These women should either learn the sugyos of tevila b’iyun or not make these halachic determinations. I have come across a few stories (first and second hand) of Mikva Women making terrible halachic mistakes with potentially grave consequences.
