Fourth Amendment

The canonical test for Fourth Amendment searches looks to whether the government has violated a person’s reasonable expectation of privacy. Yet the Supreme Court has recently added a property-based test to address cases involving physical intrusions. Further, influential judges and scholars have proposed relying primarily on property in determining the Fourth Amendment’s scope. This Article exposes the overlooked flaws of a property-centered Fourth Amendment. It examines the complications of property law, explores the malleability of property rights, and reveals how governments can manipulate them. Normatively, Fourth Amendment regimes based on property are likely to be underinclusive and grounded in trivial physical contact while ignoring greater intrusions. Finally, because property is unequally distributed, its use as a determinant of Fourth Amendment protections risks leaving disadvantaged members of society with the least protection. While property concepts will sometimes be relevant, they should be used very carefully, and very little, in Fourth Amendment law.
