Here is the Michigan Court of Appeals decision in Devlin v. Attorney General — Devlin vs Attorney General MI Ct of App.

An excerpt:

On June 3, 2008, plaintiff filed his complaint for mandamus against attorney general Michael A. Cox in his official capacity. Plaintiff averred that casinos and other businesses owned by Indian tribes in Michigan are selling spirits, beer, and wine on their premises, but are doing so without a license issued by the Michigan Liquor Control Commission as required by law. Plaintiff further averred that defendant, as the State’s chief law enforcement officer, had knowledge of these “tribal liquor license violations.” And, although “hundreds of thousands of felony violations have been committed by Michigan tribal casino management” . . . defendant “fails and refuses to take any corrective action, whether it be a civil suit against the tribes for a declaratory and injunctive Order . . . or criminal actions against tribal management.” Plaintiff alleged that he and other travelers on State highways are in danger because “[a]ll of the tribal casinos are located within a minute or two drive to State highways” and underage customers, as well as intoxicated persons, are likely to leave the casinos and drive on State highways. Accordingly, plaintiff alleged, defendant’s failure to enforce State liquor licensing laws under these circumstances constituted a clear abuse of discretion and warranted the issuance of a writ of mandamus to command him to act.

Here was the complaint filed in 2008.
