Utah's Supreme Court has rejected a petition from members of a southern Utah-based polygamous sect seeking a reversal of changes made to its communal land trust.

In a ruling issued Friday, justices say members of the Fundamentalist Church of Jesus Christ of Latter Day Saints waited too long to challenge the state's intervention in the United Effort Plan Trust.

Valued at $110 million, the trust holds the property in Hildale, Utah and Colorado City, Ariz., the twin border towns where most church members live.

Utah seized the trust in 2005 after allegations of mismanagement by church leaders. A court-appointed accountant has since converted the trust into a secular entity.

FLDS members consider state control of the UEP a violation of their religious rights.
