Has there been any news about follow-ups to this?
Will his license be pulled for discrimination against a protected class? Has it been yet? (Sorry if this has already been addressed. I haven't read the whole thread.)
Well, no that could be a protracted process.
If someone were to identify himself as Muslim, and be denied service for that factor only, then the injured party could file suit in Federal court for damages, citing the CRA.
A court order would likely be issued enjoining the business owner from withholding services to the Muslim patron. If services are provided accordingly only the issue of damages is reviewed.
If the business owner continues to refuse service to the Muslim patron, the business owner could find himself in contempt and subject to a fine or imprisonment.
