Final answer:
Unlawful searches are a violation of procedural criminal law, which is informed by the Fourth Amendment's protection against illegal searches and seizures and the concept of due process.
Step-by-step explanation:
Unlawful searches are a violation of procedural criminal law. This principle is derived from the Fourth Amendment of the US Constitution, which protects individuals from illegal searches and seizures of their property. Legal proceedings involving questions of search and seizure often on the reasonableness of the search and whether proper due process has been followed. Due process, comprised of both procedural and substantive elements, is a fundamental legal requirement that mandates the government to respect the rights of individuals.
