evidence laws

Evidence laws determine what information can be presented in court to prove or disprove a fact in a case. They set rules about which types of evidence—such as documents, witness testimony, or physical objects—are acceptable and how they must be handled. The goal is to ensure the process is fair, reliable, and avoids prejudice. Evidence must typically be relevant, meaning it relates directly to the case, and often must be obtained lawfully. These rules prevent unfair influence and help judges and juries decide based on trustworthy information.
