The term "abuse of discretion" refers to a situation where an individual in charge of making decisions, such as a judge or administrative official, acts outside the bounds of their authority and makes a decision that is deemed unfair or unreasonable. In legal proceedings, this phrase can be used to describe a ruling that was not supported by evidence or proper consideration of the facts, indicating that the judge has acted beyond their scope of discretion in making the decision. The concept of abuse of discretion is often used as grounds for appeal when an individual believes they have been treated unfairly by a legal authority.
