An impermissibly suggestive lineup violates which constitutional clause?

• A. First Amendment
• B. Fourth Amendment
• C. Fifth Amendment
• D. Sixth Amendment

Answer: (C)

An impermissibly suggestive lineup primarily violates the due process rights protected under the Fifth Amendment. The Fifth Amendment includes provisions that ensure no person shall be deprived of life, liberty, or property without due process of law. When a lineup is so suggestive that it leads to a substantial likelihood of mistaken identification, it undermines the fairness of the judicial process and can lead to wrongful convictions. Courts aim to protect individuals from unreliable eyewitness testimony derived from suggestive identification procedures, recognizing that such practices can severely compromise the integrity of legal proceedings.

In discussions of criminal procedure, the focus is often on how the rights of the accused are upheld, including the fairness of identification processes. The implications of an impermissibly suggestive lineup directly connect to the due process standard, as it does not ensure the reliability of witness identifications that are critical in establishing guilt or innocence. Other constitutional clauses, such as those found in the First, Fourth, and Sixth Amendments, do not specifically address the issue of suggestive lineups or its impact on due process in the temporal context of a lineup, focusing instead on different rights and protections afforded to individuals.
