The American Gaming Association adopted new rules on March 28, which would disallow partnerships between colleges and sports-betting companies, challenging Michigan State Athletics’ nearly $9 million deal with Caesars Sportsbook, according to the association’s website.

The American Gambling Association, or AGA, is not a government agency, rather a group of casinos and online gambling firms that regulate the industry through an internally-enforced code of rules. Caesars is not a member of the AGA, but is still bound by the guidelines it creates, according to AGA Senior Vice President Casey Clark.

Individuals and members are asked to submit complaints to the AGA if they suspect firms of breaking their rules, those would then be investigated by a review board, according to the organization’s policy
