If evidence is obtained illegally, is it admissible in court?

Evidence obtained illegally is deemed inadmissible in court primarily due to the exclusionary rule, which is designed to deter law enforcement from violating individuals' rights. This rule upholds the Fourth Amendment protection against unreasonable searches and seizures, ensuring that any evidence obtained in violation of constitutional rights cannot be used in legal proceedings.

In practical terms, an illegal acquisition includes scenarios such as searches conducted without a warrant, consent, or probable cause, as well as evidence obtained through coercion or in violation of legal procedures. The intent is to maintain the integrity of the judicial system and protect citizens from unlawful government actions. Thus, any evidence that does not adhere to these legal standards is excluded, reinforcing the principle that the ends do not justify the means in criminal justice.
