Well, at least they don't expose themselves to civil liability by doing so. The system is generally designed so that judges don't have to answer to the participants in the cases they are presiding over. That doesn't mean they don't answer to anyone.
In practice the entire system has become political, corrupted or both. As a result, the only rights most people have are those where officers of a court are only limited by where their immunity ends. They can and do violate the law and ignore large parts of it if it suits them.
Assuming someone has the resources to even get any oversight at all, in most cases those involved will investigate each other and decide they have done nothing wrong. Even in the unlikely event that someone proves an illegal act, they will just claim immunity.
You would probably have a really good shot at an appeal, too.
