Every now and then one hears of some corrupt judge being removed for one reason or the other. I have participated in litigation where one of the participating judges (the first one) was jailed and barred from practicing law for life (my contribution to his demise was <1%).
Rather than waiting for these judges' infractions to accumulate and then explode in a scandal, what are soft, legal ways to remove a judge? For instance, you might see bias and continuous favoring of one party (late filing OK, faulty filing OK, etc.).
If I remember correctly, there is something (at least in US federal laws) like you do not need to prove impropriety, it is enough to have an impression of impropriety by a judge.
What are the laws that govern recusal/removal of a judge in State and Federal cases?
