LONGMONT — A judge is considering whether to overturn Longmont's fracking ban, which energy companies and state regulators say violates state law and legal precedent.

Boulder District Court Judge D.D. Mallard listened to arguments on the 2012 voter-approved ban on Wednesday and said she would issue a written decision later.

The Colorado Supreme Court ruled in 1992 that cities can't completely ban drilling although the court said they weren't completely forbidden from regulating oil and gas development.

The Longmont Times-Call reports that city attorneys argue companies can still use other drilling methods besides hydraulic fracturing in Longmont.

The judge could decide to overturn the ban immediately or to hold a trial to hear more evidence.
