What rule prevents the use of illegally obtained evidence in court?

The Exclusionary Rule is a legal principle that prohibits the use of evidence collected or analyzed in violation of a defendant's constitutional rights. This rule was established to protect individuals from unlawful searches and seizures, ensuring that evidence obtained through illegal means cannot be used in court to prove guilt. The rationale behind this rule is to deter law enforcement from engaging in misconduct and to uphold the integrity of the judicial system. Consequently, any evidence gathered without proper warrants, probable cause, or in violation of constitutional protections is deemed inadmissible, thereby safeguarding the rights of the accused. This rule plays a crucial role in maintaining fair trial standards and protecting civil liberties.
