SALT LAKE CITY -- Attorneys for a southern Utah polygamous church are asking a judge to reverse the sale of cows from a church farm by a court-appointed accountant.

Papers filed in 3rd District Court say the sale of 565 heifers from Harker Farms in Beryl decimates the value of the farm -- a key asset in settlement negotiations over the United Effort Plan trust.

Once controlled by jailed church leader Warren Jeffs, the UEP is an arm of the Fundamentalist Church of Jesus Christ of Latter Day Saints. The UEP was seized by the Utah courts in 2005 after allegations of mismanagement. The FLDS are now negotiating to regain most trust assets.

FLDS attorneys say fiduciary Bruce Wisan and his attorneys should have disclosed plans to sell the cows during negotiations.
