When a jury is to be selected from the jury list of the district, the justice shall draw from the box in the presence of the parties, or select by means of electronic equipment, 12 ballots or names, or any greater number, if necessary, until the names of 12 persons, who are deemed able to attend at the time and place required, are obtained. The justice must make and sign a list of the 12 names thus drawn. [Amended by 1983 c.673 § 17]
