Answer:
the exclusionary rule.
Explanation:
The exclusionary rule basically applies to all the evidence gathered illegally, or in violation of your constitutional guarantees. Generally this type of exclusions are for evidence obtained while breaching your fourth amendment rights, but it can apply to all the violations of the fifth and sixth amendments.
The Supreme Court established the exclusionary rule in Mapp v. Ohio (fourth amendment violations) and Miranda v. Arizona (fifth and sixth amendment violations).
