The exclusionary rule prohibits the use of evidence obtained unlawfully in court. This legal principle is designed to protect the rights of individuals by ensuring that law enforcement and government officials adhere to constitutional standards when conducting searches and seizures. Specifically, if evidence is collected in violation of a person's Fourth Amendment rights—such as through unreasonable searches or without a proper warrant—then that evidence cannot be presented in a criminal trial.

This is crucial for maintaining the integrity of the judicial system and upholding due process, as admitting such evidence would effectively condone the unlawful actions of authorities. The exclusionary rule serves as a deterrent against illegal investigative practices, thereby reinforcing the rule of law.

While hearsay evidence and witness testimony can have their own rules and limitations, they are governed by different legal standards than those established under the exclusionary rule. Similarly, confessions obtained under duress address the admissibility of statements made by a suspect, but this concern falls under separate legal protections, such as those against self-incrimination.
