Legal Question in Constitutional Law in California

If judges don't follow proper procedures, the legal remedy is that the aggrieved party has the constitutional right to petition a higher court for redress of grievances (in other words, to appeal). Judges who repeatedly or blatantly err can be disciplined or removed from office.

Mr. Stone is right. Judges are immune from civil lawsuits against them for actions taken in their official capacity. If they weren't, disgruntled parties would sue them all the time.

Note that equal protection violations usually involve discrimination, not mere bias. That a judge seems to treat one party better than another would only violate equal protection if he did it because the disfavored party was a member of a particular gender, race, religion, etc. Even then, the remedy is through an appeal or a writ petition, not a lawsuit against the judge.
