Minnesota Statutes § 204B.22 ELECTION JUDGES; NUMBER REQUIRED

(a) A minimum of four election judges shall be appointed for each precinct in the state general election, provided that a minimum of three election judges shall be appointed for each precinct with fewer than 500 registered voters as of 14 weeks before the state primary. In all other elections, a minimum of three election judges shall be appointed for each precinct. In a combined polling place under section 204B.14 , subdivision 2, at least one judge must be appointed from each municipality in the combined polling place, provided that not less than three judges shall be appointed for each combined polling place. The appointing authorities may appoint election judges for any precinct in addition to the number required by this subdivision including additional election judges to count ballots after voting has ended.

(b) An election judge may serve for all or part of election day, at the discretion of the appointing authority, as long as the minimum number of judges required is always present. The head election judge designated under section 204B.20 must serve for all of election day and be present in the polling place unless another election judge has been designated by the head election judge to perform the functions of the head election judge during any absence.
