The Fourth Amendment to the United States Constitution guarantees the right of individuals to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures. It requires law enforcement to obtain a warrant, based on probable cause, before conducting searches or making arrests in most situations.
The search or seizure must be conducted by a government agent or an individual acting under governmental authority.
What to prove: It must be shown that the action in question was undertaken by law enforcement or government officials.
The individual must have a reasonable expectation of privacy in the area or object to be searched or seized.
What to prove: It must be demonstrated that a person had a subjective expectation of privacy that society recognizes as reasonable.
Search warrants must be based on probable cause, supported by oath or affirmation, describing the place to be searched and the persons or things to be seized.
What to prove: The party challenging the search must establish that the warrant lacked probable cause, or that no warrant was issued when one was required.
The search or seizure must be deemed unreasonable under the circumstances.
What to prove: It must be shown that the search was not justified by exigent circumstances, consent, or other exceptions to the warrant requirement.
The burden of proof generally lies with the defendant to demonstrate that the search was unreasonable; the standard of proof is preponderance of the evidence.
Focus on identifying government action, expectations of privacy, and whether probable cause was properly established when analyzing cases related to the Fourth Amendment.
