[Avodah] Psulei edus invalidating the whole group

[Zev Sero]

Does this apply only to people who could be in the geder of edus, if
only they weren't relatives, cardsharps, or whatever?   In other words,
if women are included among the witnesses, can we say that they don't
invalidate the male witnesses, because they're not even potentially
kosher, so they're as if they weren't there?
