Constitutional protections, primarily the Fourth, Fifth, and Sixth Amendments, safeguard individuals from illegal evidence. The Fourth Amendment protects against unreasonable searches and seizures, the Fifth against self-incrimination, and the Sixth ensures the right to a fair trial. Lawyers can rely on these protections to seek exclusion by filing a motion to suppress, arguing that the evidence was obtained unlawfully—such as through an illegal search, coercion, or a violation of due process. If the court denies the motion, the lawyer must make a formal objection on the record to preserve the issue for appeal, ensuring the constitutional rights are upheld in the trial process.
