Michigan v. Tyler, , is a United States Supreme Court case in which the Court held that firefighters can not enter a burned premises (in this case, a furniture store) to retrieve evidence of arson barring a search warrant, evidence of exigent circumstances, evidence of abandonment, or consent.
Justice William Rehnquist argued that due to Tyler's actions, and business being unlikely to resume until major repairs are completed, the subsequent searches were reasonable under the circumstances.
