A more thorough explanation:

Definition: Ex arbitrio judicis is a Latin term used in civil law. It means that a decision is made at the discretion of the judge.

Example: In a court case, the judge may have to make a decision based on the evidence presented. If there is no clear answer, the judge may have to make a decision ex arbitrio judicis, meaning that they will use their own judgment to make a ruling.

Explanation: This term is used to describe a situation where the judge has to make a decision based on their own judgment, rather than following a specific law or rule. It gives the judge the power to make a decision that they believe is fair and just, even if it is not explicitly stated in the law.
