What promises to be a lengthy vetting process for would-be Massachusetts casino developers has officially begun.

The state's gaming commission planned on Oct. 19 to make available on its web site Phase 1 applications for developers seeking one of the three licenses for destination resort casinos permitted under the nearly one-year-old gambling law.

The applications are due back within 90 days and must be accompanied by a $400,000 fee.

Support for GBH is provided by:

The commission will review the submissions from developers to determine if they are qualified financially and have no outstanding legal or ethical issues that would disqualify them from bidding for a license.

Applicants that pass the first test will be allowed to move on to the Phase 2 application process and bid competitively for one of the regional casino licenses.
