Col­orado vot­ers have passed a mea­sure that will require the state to request vot­ers’ per­mis­sion before cre­at­ing cer­tain new state enterprises.

Propo­si­tion 117 means law­mak­ers will have to put on the bal­lot any new fees expect­ed to bring in at least $100 mil­lion from fees and sur­charges in the first five years.

Oppo­nents con­ced­ed late Thurs­day after­noon. With 91% of the statewide vote count­ed, Prop 117 had received almost 53% support.

The cam­paign for the mea­sure was led by con­ser­v­a­tive groups, with Col­orado Ris­ing State Action tak­ing the lead. Pro­po­nents said it was a way to close what they call a loop­hole in the Taxpayer’s Bill of Rights, which requires approval of any new tax­es but not new fees.

Oppo­nents, how­ev­er, argued that the mea­sure could hurt essen­tial pro­grams for Coloradans.
