A law that prevents illegally obtained evidence from being used in court according to the text is a law?

A law that prevents illegally obtained evidence from being used in court is known as the "exclusionary rule." This legal principle is designed to uphold the rights of individuals by ensuring that evidence obtained in violation of their constitutional rights, such as through unlawful searches and seizures, cannot be admitted in court. The rationale behind this rule is to deter law enforcement from engaging in illegal practices and to maintain the integrity of the judicial process.
