St. Paul City Council Member Dai Thao acted legally when he helped a woman vote in an election last year in which he was a mayoral candidate, a judge ruled late Friday.
Ramsey County District Court Nicole Starr issued a decision stating that Thao was not guilty of any of the criminal charges filed against him.
"At every step of the voting process, Defendant was open and transparent about his aid to a non-English speaking voter," Starr wrote. "He encountered several election judges, who actively worked with him to ensure that the non-English speaking voter understood the process and was able to cast her vote."
Chief Deputy Dakota County Attorney Phil Prokopowicz, who is prosecuting the case to avoid a conflict of interest in Ramsey County, could not be reached for comment Friday.
Prokopowicz said last month that he would have to review Starr's decision before deciding what steps he might take.
"I'm very grateful," Thao said in an interview. "We need to do more to help enable people with disabilities and language barriers to exercise their constitutional right" to vote.
Thao, 43, was charged in February with three misdemeanor counts of unlawfully marking a ballot, misconduct in and near polling places and unlawfully assisting a voter.
Minnesota law prohibits candidates for office from assisting voters in a polling place.
