second group shall hold currently, or shall have held previously, appointments as lay assessors of a court of general jurisdiction or a public administrative court. Art. 4. Jurors are appointed, by election, for a period of four calendar years. Jurors shall be elected by the county council of the county administrative district or, where the county administrative district includes a municipality which does not come under the county council, by the county council and the council of the municipality concerned. Jurors in the Gotland county administrative district are elected by the Gotland municipal council. If, under the foregoing, jurors are to be elected by more than one electoral body, the county administrative board shall apportion the number of jurors in each group among the electoral bodies in proportion to population. When a juror is to be elected the district court shall notify the authority responsible for arranging the election to this effect. Art. 5. Jurors shall be appointed from among Swedish citizens domiciled in the county administrative district for which they are to be appointed. They should be known for their soundness of judgment, independence and fairmindedness. Different social groups and currents of opinion, and different parts of the county administrative district, should be represented among the jurors. No person who is a minor or for whom an administrator has been appointed under special provisions of law may be a juror. Art. 6. A juror who has attained the age of sixty has the right to resign his or her appointment. If in any other circumstances a juror wishes to retire, the district court considers whether valid cause exists to prevent him or her from carrying out his or her duties. If a juror ceases to be eligible for election, the appointment lapses. Art. 7. If a juror retires or ceases to be eligible for election, the electoral body shall appoint another person from among the group of jurors to which he or she belonged to replace him or her for the remainder of the electoral period. Such a juror may be elected by the county council executive committee in place of the county council: such an election is however valid only until the county council next meets. 239
