Here is the opinion in State v. Yang. An excerpt:

Appellant challenges his convictions of three counts of controlled substance crime in the first degree, arguing that security guards employed by the Mystic Lake Casino Hotel violated his Fourth Amendment protections under the Indian Civil Rights Act and the United States Constitution when they conducted a warrantless search of his satchel in a hotel room and discovered methamphetamine and marijuana. Because the security guards were not acting as tribal governmental agents, appellant’s rights under the Indian Civil Rights Act were not violated. We affirm.
