Barlow’s Inc. was an electrical and plumbing contractor. An OSHA inspector appeared at Barlow’s place of business and asked to inspect the premises. There had been no injuries at Barlow’s and the inspector did not possess a search warrant. Barlow’s denied the inspector access to the business. OSHA sued to compel Barlow to admit the inspector without a warrant. Who prevails, Barlow or OSHA? (Marshall v. Barlow’s Inc., 436 U.S. 307)
