The District Attorney's Office

Mission of the District Attorney’s Office

To maintain public safety while seeking justice in every case, and to enhance the legacy of the Boulder County District Attorney’s Office as a leader in public safety, progressive prosecution, and criminal justice reform.


The Office of the District Attorney has jurisdiction, or authority, over violations of state criminal laws and is responsible for upholding the Colorado and United States Constitutions. The District Attorney serves an Executive Branch function, which means it is responsible for enforcing Colorado state criminal laws as created by the Legislature. The District Attorney’s Office does not have jurisdiction over City Code or Ordinance violations or regulatory codes.

The prosecutor has more control over life, liberty, and reputation than any other person in America…The citizen’s safety lies in the prosecutor who tempers zeal with human kindness, who seeks truth and not victims, who serves the law and not factional purposes, and who approaches his task with humility.

~ Justice Robert Jackson
