evidentiary rule

An evidentiary rule is a legal guideline that determines what information or proof can be presented in a court case. Its purpose is to ensure that only relevant, reliable, and fair evidence is considered, helping the court make a fair decision. These rules prevent introducing false, misleading, or prejudicial information. For example, some rules limit the use of hearsay (secondhand information), while others specify how documents or witness testimony should be handled. Overall, evidentiary rules promote justice by maintaining the integrity and clarity of the evidence used in legal proceedings.
