The Weeks v. United States case is a landmark case that lays the foundation for exclusion rules that prevent illegally obtained evidence from being used in federal courts. In its decision, the Court unanimously supported the Fourth Amendment’s protection against unwarranted searches and seizures. In 1911, Fremont was suspected of delivering lottery tickets by mail, violating the “criminal law.” Officials in Kansas City, Missouri, arrested his work in his work and searched his office. Later, the police also searched the home of Zhou and seized evidence including documents, envelopes and letters. The search did not appear in the week and the police did not have an arrest warrant. The evidence was handed over to Marshalls in the United States. Based on this evidence, Marshalls conducted a follow-up search and seized other documents. Before the court heard, Weeks’ lawyer asked the court to return the evidence and prevent the local prosecutor from using the evidence in court. The court rejected the petition and Weeks was convicted. Mr. Zhou appealed the conviction on the grounds that the court violated his Fourth Amendment protection measures and prevented illegal searches and seizures through unwarranted searches and use of the searched products in court. The main constitutional issues raised in the Weeks v. United States case were whether the federal agent legally conducted unreasonable searches and confiscation of someone’s domicile, and whether the illegally obtained evidence could be used by someone in the court.
