What is the test for asserting Fourth Amendment rights vicariously?

Fourth Amendment rights cannot be asserted vicariously. Rakas v. Illinois, 439 U.S. 128, 134, 58 L. Ed. 2d 387, 99 S. Ct. 421 (1978); United States v. Johns, 851 F.2d 1131, 1135 (9th Cir. 1988). In order to claim the protections of the Fourth Amendment here, Defendants must establish that they had an expectation of privacy in the shed and that their expectation was reasonable. Minnesota v. Carter, 525 U.S. 83, 88, 142 L. Ed. 2d 373, 119 S. Ct. 469 (1998). The reasonableness of an expectation of privacy is evaluated "either by reference to concepts of real or personal property law or to understandings that are recognized and permitted by society." Rakas, 439 U.S. at 143 n.12. Defendants have the burden of establishing that, under the totality of the circumstances, the search or the seizure violated their legitimate expectation of privacy. Sarkisian, 197 F.3d at 986.
