Under what conditions can evidence obtained by an officer be excluded in court?

Evidence obtained by law enforcement can be excluded in court primarily when it is acquired in violation of constitutional laws. This principle is rooted in the Fourth Amendment, which protects individuals from unreasonable searches and seizures. If evidence is obtained without a proper warrant, probable cause, or proper adherence to legal protocols, it may be deemed inadmissible in court.

This exclusionary rule serves to deter law enforcement from violating individuals' rights and upholds the integrity of the judicial process. For example, evidence uncovered during an unlawful search without a warrant or probable cause can be excluded because it infringes on the constitutional rights of the individual involved.

While relevance plays a critical role in the admissibility of evidence, and proper documentation can impact its credibility, the core issue concerning constitutional violations is what gives rise to the most significant ground for exclusion in legal proceedings. If evidence fails to comply with constitutional standards, it fundamentally undermines the fairness of the judicial system.
