Lawyers for Minnesota sex offenders in a confinement program deemed unconstitutional are urging a federal judge to keep the pressure on the state to make changes.

In a brief filed Wednesday, the attorneys said U.S. District Judge Donovan Frank should deny a state motion to suspend his order spelling out a list of mandated changes.

The Minnesota attorney general's office along with key state officials want Frank to issue a stay of last week's ruling while they appeal his order. That appeal has been filed. Frank ordered the more than 700 offenders in two secure treatment facilities to be urgently re-evaluated, with those no longer seen as a serious risk moved to less-restrictive settings.

Their attorney, Dan Gustafson, said suspending the ruling would only further an unconstitutional loss of liberty.
