KUSA - Fracking opponents notched a victory in a Colorado court on Thursday as a judge upheld the result showing a that voters narrowly approved a 5-year ban on hydraulic fracturing in the city of Broomfield.

The result originally showed that question 300 had failed by 13 votes. A later mandatory recount found that the question had actually passed by 20 votes, a result upheld by the court.

District court judge Chris Melonakis wrote in his order that city officials "substantially complied with the election laws of the State of Colorado and that the election should not be set aside."

The Broomfield Balanced Energy Coalition, a pro-oil and gas industry group that sued over the outcome of the election, is considering its options.

If the judge's ruling stands, it will mean that all four local government ballot questions to limit fracking succeeded in November.
