What is the "exclusionary rule"?

The "exclusionary rule" is a legal principle that prohibits the use of illegally obtained evidence in court. This rule exists to protect the Fourth Amendment rights of individuals, which guard against unreasonable searches and seizures. When law enforcement officials gather evidence in violation of these rights, such as without a proper warrant or probable cause, that evidence cannot be used in a court of law. The rationale behind the exclusionary rule is to deter law enforcement from engaging in unlawful procedures and to maintain the integrity of the judicial system.

This principle serves as a safeguard for ensuring that evidence is collected lawfully and that individuals are treated fairly under the law. By excluding improperly obtained evidence, the judicial system reinforces the importance of adhering to constitutional rights, thereby promoting justice and upholding public confidence in the legal process.
