The General Assembly shall, from time to time, divide the State into a convenient number of Superior Court judicial districts and shall provide for the election of one or more Superior Court Judges for each district. Each regular Superior Court Judge shall reside in the district for which he is elected. The General Assembly may provide by general law for the selection or appointment of special or emergency Superior Court Judges not selected for a particular judicial district.

  (2) Open at all times; sessions for trial of cases. The Superior Courts shall be open at all times for the transaction of all business except the trial of issues of fact requiring a jury. Regular trial sessions of the Superior Court shall be held at times fixed pursuant to a calendar of courts promulgated by the Supreme Court. At least two sessions for the trial of jury cases shall be held annually in each county.

  (3) Clerks. A Clerk of the Superior Court for each county shall be elected for a term of four years by the qualified voters thereof, at the same time and places as members of the General Assembly are elected. If the office of Clerk of the Superior Court becomes vacant otherwise than by the expiration of the term, or if the people fail to elect, the senior regular resident Judge of the Superior Court serving the county shall appoint to fill the vacancy until an election can be regularly held.
