Whether DeForte had Fourth Amendment standing to object to the use of union-owned records seized from the shared union office where he worked.
Holding
Yes. DeForte had standing because the warrantless governmental entry and search invaded an area in which he reasonably expected freedom from governmental intrusion.
Reasoning
Fourth Amendment protection is not confined to a person's home or to premises the person owns. It extends to commercial offices, and the inquiry does not turn on formal property title. Under Jones and Katz, the essential question is whether the person had a sufficient connection to the searched area and a reasonable expectation that the Government would not intrude there.
DeForte spent a considerable amount of time in the union office, shared it with other union officials, and had custody of the seized records when officials took them. Although the room was not reserved exclusively for him and the records belonged to the union, he reasonably could expect that entry would be limited to fellow officials and their legitimate guests, and that union records would not be removed without authorization from those entitled to give it.
Sharing the office did not fundamentally eliminate that expectation. A union official in a shared office retains a legitimate expectation against an unconsented governmental entry, general search, and removal of records in his custody. The fact that the union or superior officials might have been able to consent was irrelevant because no actual or implied consent was claimed.
Jones supported this conclusion. Like Jones, DeForte was legitimately present in premises he did not own, had no absolute right to exclude all others, and did not claim exclusive control over the exact area from which the evidence was taken. Yet the Government's intrusion into the area where he worked was sufficiently personal to permit him to challenge the evidence's use against him.
