MONTICELLO, N.Y. (AP) — The St. Regis Mohawk tribe in northern New York has voided a referendum last month that would have ended the tribe's efforts to build an off-reservation casino in the Catskills.

The tribe announced Monday that it's election board nullified the results after determining that the Nov. 21 vote didn't meet a 30-day public posting requirement.

The referendum asked tribe members whether the Mohawks should pursue development of a casino in Sullivan County. There were 178 "no" votes and 140 "yes" votes.

The tribe has spent much of the past decade working to get approval for a casino in Monticello, 230 miles south of its reservation on the New York-Quebec border.

Tribal officials say another referendum will be held on a date yet to be determined.
