Evidence Law is a set of rules that governs what information can be presented in a legal proceeding. It determines which evidence is admissible in court, ensuring that only relevant and reliable information is considered by judges and juries. This helps maintain fairness in the legal process. The main types of evidence include witness testimony, documents, and physical evidence. Each type has specific rules regarding how it can be used. For example, hearsay—information not based on a witness's direct knowledge—is generally not allowed, as it may not be reliable.
