BOSTON (AP) — The Massachusetts Gaming Commission released its written decision Thursday denying Boston residents the right to vote on casino proposals for neighboring Revere and Everett, as casino opponents called for a state investigation into the Boston-area casino licensing process.

The commission voted last week to deny Boston’s request to be named a “host community” for Wynn’s proposed $1.5 billion casino on a former industrial site in Everett and for Mohegan Sun’s more than $1 billion project on land in Revere to be leased from the Suffolk Downs horse racing track.
