What do the "four corners" of a search warrant refer to?

The concept of the "four corners" of a search warrant refers specifically to the totality of the information contained within the physical document, including all written contents such as the description of the property to be searched, the items to be seized, and the probable cause supporting the warrant. This principle underscores the importance of the warrant as a legal document that must clearly articulate its purpose and justification.

Focusing solely on the contents within the document ensures that law enforcement acts within the authority granted by the courts. Courts will only examine what is explicitly stated within these "four corners" to assess the legality of the search, as external factors or notes that are not part of the warrant itself do not provide legal justification for the actions taken during the search.
