What does the exclusionary rule pertain to?

The exclusionary rule is a legal principle that prohibits the use of evidence obtained in violation of a defendant's Fourth Amendment rights, which protect against unreasonable searches and seizures. This means that any evidence acquired through illegal means, such as an unlawful search or without a proper warrant, cannot be presented in court. The purpose of this rule is to deter law enforcement from engaging in unlawful practices and to uphold constitutional rights.

By ensuring that illegally obtained evidence is not admissible in court, the exclusionary rule serves to maintain the integrity of the judicial process and protect individual liberties. The rule is crucial for reinforcing the principle that law enforcement must adhere to the law and respect citizens’ rights during investigations.
