What is the exclusionary rule in criminal procedure?

The exclusionary rule in criminal procedure is a legal doctrine that prevents unlawfully obtained evidence from being used in court. This doctrine, which applies in both the state of Arizona and to the federal government, states that evidence that is obtained in an illegal manner is inadmissible in a court of law. This prevents law enforcement officers from obtaining evidence in violation of either state or federal constitutional law without consequence. The purpose of the exclusionary rule is to discourage police misconduct. For example, if police officers were allowed to illegally search someone’s home, and they still used any evidence they obtained, then that would create an incentive for police officers to violate the rights of citizens. Additionally, the exclusionary rule serves as a check on the power that police officers have, as the evidence obtained as a result of an illegal search cannot be used in court. In Arizona, the exclusionary rule applies to evidence obtained illegally or in violation of an individual’s constitutional rights. This includes evidence obtained without a warrant or without probable cause that a crime has been committed. Additionally, any evidence obtained as a result of an illegal arrest or through means of coercion is also inadmissible in court. The exclusionary rule is an important part of criminal procedure in Arizona. By preventing the use of illegally obtained evidence in court, it helps to protect the civil liberties of individuals and ensures that law enforcement officers are not abusing their power.
