Begun the offshore sportsbook war has.

At least in Michigan. At least with one offshore sportsbook, as the Michigan Gaming Control Board (MGCB) has sent a cease-and-desist letter to Harp Media B.V., which operates Bovada.com.

The company, based in Curacao, is operating an illegal gaming site available to Michigan residents, the MGCB says.

“The proliferation of online gaming platforms has led to increased scrutiny from regulatory bodies worldwide, and this action serves as a stern warning to overseas companies that flouting local regulations will not be tolerated,” MGCB Executive Director Henry Williams said in a press release. “The MGCB remains steadfast in its commitment to upholding Michigan’s laws and regulations and will continue to actively monitor and enforce compliance within the state to ensure a fair and secure gaming environment for all.”

According to the complaint, Bovada is in violation of numerous Michigan gaming laws, including:

The Lawful Internet Gaming Act, which states only Michigan-licensed gaming companies can offer their products in the state.

The Michigan Gaming Control and Revenue Act, which doubles down on the licensing requirements with punishments of up to 10 years in prison.

The Michigan Penal Code, which broadly prohibits most forms of gambling.

Harp Media B.V. has 14 days from receipt of the letter to take steps to prevent Michigan residents from gambling on their websites or the MGCB will take legal action.
