When do private store employees become government agents for Fourth Amendment purposes? Orem City v. Santos Explained

In Orem City v. Santos, the Utah Court of Appeals examined when private store employees conducting shoplifting investigations constitute state actors subject to Fourth Amendment protections. The decision clarifies the boundaries between legitimate private security actions and government searches.

Background and Facts
Santos was shopping at Costco when employees observed suspicious behavior suggesting retail theft. The employees detained Santos in the store’s office, questioned her about unpaid merchandise, searched her purse and stroller, requested identification, and called police. After her conviction for retail theft, Santos appealed, arguing the employees’ actions violated her Fourth Amendment rights because they acted as government agents.

Key Legal Issues
The central question was whether Costco employees conducting the investigation constituted state actors whose conduct must comply with Fourth Amendment requirements. Santos argued that Utah’s merchant detention statutes (Utah Code sections 76-6-603 and 77-7-12) gave the employees quasi-law enforcement status, making their actions government conduct.

Court’s Analysis and Holding
The court applied the two-part Walther test to determine state action: (1) whether the government knew of or acquiesced in the search, and (2) whether the private party acted primarily to assist law enforcement rather than for independent purposes. The court found neither element satisfied. Utah’s statutory authorization for merchant detention did not constitute government knowledge or acquiescence, as “mere governmental authorization of a particular type of private search” is insufficient without more active participation. Additionally, the employees acted primarily to protect Costco’s assets, not to assist law enforcement.

Practice Implications
This decision establishes important boundaries for Fourth Amendment challenges to private security actions. Practitioners should note that statutory authorization alone does not create state action—there must be actual government involvement and the private party must act primarily to assist law enforcement rather than protect private interests. The ruling provides useful guidance for both criminal defense attorneys challenging private searches and civil practitioners advising retail clients on detention procedures.
