Even if the judge has ruled in his favor (and rightly too because it was an unjust breach of privacy), the public will still view what he was doing in private as "sleezy", and if you have that tag over your head in the position that he is in, then you are seen as untrustworthy (i.e if he's doing this thing in private, then what else are you doing?) or an embarrassment (even if what he was doing wasn't illegal).

Sleeze is a stinky taint if you’re in a position of that power, and if you have it then your position becomes largely untenable.
