WASHINGTON (AP) - The Supreme Court won't hear a challenge to Minnesota's sex offender civil commitment system, which allows people deemed sexually dangerous to be committed to a treatment facility for an indefinite period of time.

The court's order, which declines to hear the case, came Monday.

According to the sex offenders who brought the lawsuit, more than 700 people are now committed in the state as ``sexually dangerous'' or a ``sexual psychopathic personality.'' They argued the ``fatal flaw'' in the scheme is that Minnesota doesn't require a regular review of those cases to see if the individuals should still be held.

Minnesota told the court that offenders can petition for release using a simple-to-obtain form.
