C.R.S. § 37-43-161

If no such proceeding has been filed by the board of directors within thirty days after the canvass of said vote, then any qualified elector of the district may bring an action in the district court of the county wherein the office of the board of directors is located. The board of directors shall be made parties defendant, and notice shall be served on the members of the board personally if they can be found in the county; if not, then service by publication as provided in section 37-43-159 shall be sufficient. Proceedings shall be had in the same manner and with the same effect as if brought by the board of directors.
