The chief judge of the district court, or such other district court judge as the plan may provide, on his initiative or upon recommendation of the clerk or jury commission, or the clerk under supervision of the court if the court’s jury selection plan so authorizes, shall determine solely on the basis of information provided on the juror qualification form and other competent evidence whether a person is unqualified for, or exempt, or to be excused from jury service. The clerk shall enter such determination in the space provided on the juror qualification form and in any alphabetical list of names drawn from the master jury wheel. If a person did not appear in response to a summons, such fact shall be noted on said list.
