What is typically the result of the "Exclusionary Rule" in court proceedings?

The Exclusionary Rule plays a significant role in preserving the integrity of legal processes by ensuring that any evidence obtained in violation of a defendant's constitutional rights cannot be used in court. Specifically, this principle aims to deter law enforcement from engaging in illegal search and seizure practices by rendering such evidence inadmissible during trial.

This rule is rooted in the Fourth Amendment, which protects individuals against unreasonable searches and seizures, and its objective is to uphold citizens' rights and maintain public trust in the judicial system. As a result, when courts apply the Exclusionary Rule, any evidence gathered through unauthorized methods or without proper legal grounds is deemed inadmissible, which can significantly influence the outcome of a case.

In contrast, the other options do not accurately describe the function or purpose of the Exclusionary Rule. For example, allowing all evidence to be used directly contradicts this principle, as does decreasing the burden of proof for the prosecution. Prior arrests may indeed be referenced in certain contexts, but they are not inherently influenced by the Exclusionary Rule. Hence, the primary result of the Exclusionary Rule is the prohibition of the use of illegally obtained evidence, solidifying the correct answer.
