The Sefer Hachinuch clearly acknowledges that if the people are mekabel her then she can be a dayan and he also acknowledges that there are those who hold that a woman can stam be a dayan. Granted the Birchei Yosef (Choshen Mishpat 7:11) writes ??????? ?? ??? ??? ?? ????? ????? ????? ???? ???? ???”? ??????? ?? ????? ?? ???? ??? ???????.
Anyway the Birchei Yosef then says ?? ???? ????? ???? ??? ???? ??? ???? ????? ?????? ????? ??? ????? ???????? ??? ??????? ?????? ???? ????? ??? ????? ??? ???? ???? ?????? ?????? ?”? ????? ???? ????? ???? ?????? ??”? ????? ???? ??? ??”? ?????? ??????? ???’ ??? ???? ???? ?????? ?????? ???’ ?”? which should allow for semicha if not for dayanus.
