4th Amendment Law

The 4th Amendment of the Constitution is a cornerstone of criminal procedure law. This is very important in criminal law. Doctrines such as "Fruit of the Poisonous Tree" have been a hallmark of criminal procedure law. The 4th Amendment of the Constitution states as follows: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized." Under the fourth amendment several criminal procedural issues arise specifically the right of unreasonable search and seizure as more fully discussed below: Moreover, warrantless searches in one’s home are per se invalid. A person has a reasonable expectation of privacy in their home. In order for there to be a valid warrant issued the fourth amendment must be satisfied and several questions must be asked and answered. Was there probable cause supported by an oath or affirmation? Was there a neutral and detached magistrate? Was the warrant properly executed and describing the place to be searched and the persons or things to seized?
