C.R.S. § 32-7-124

In any case where a notice is provided for in this article, if the court or the board reviewing the proceedings finds for any reason that due notice was not given, said body shall not thereby lose jurisdiction, and the proceedings in question shall not thereby be void or be abated, but said body shall order due notice to be given, shall continue the proceeding until such time as notice is properly given, and thereupon shall proceed as though notice had been properly given in the first instance.
