Any district judge who has retired pursuant to this article may be called by the Chief Justice to temporary active duty in any court.
The salary paid a retired district judge called to active duty shall be the salary paid a district judge in the district from which said district judge retired or the salary paid a resident district court judge in the district to which the judge is assigned, whichever is greater. In no event, however, shall the total compensation paid to a retired district judge on active duty during any calendar year exceed a sum which is $1,000.00 less than the compensation received by a regular judge in the district from which said judge is retired.
Such active duty may be terminated by order of the Chief Justice at any time.
