A more thorough explanation:

Term: fovere consimilem causam
Definition: To favor a similar case. If a judge is disqualified from a case because they have a personal interest in it, they may also be disqualified from a later case if the ruling in the first case could affect the ruling in the second case.
Example: Judge Smith is disqualified from a case involving a company he owns. Later, another case comes up involving a similar company. Even though Judge Smith doesn't have a personal interest in the second case, he may still be disqualified because the ruling in the first case could affect the ruling in the second case. This is an example of fovere consimilem causam.
