"court" includes a tribunal (however described) that exercises functions of a
judicial nature or functions of a similar nature (such as conciliation
functions, arbitration functions, disciplinary functions or administrative
review functions).
"judicial office" extends to the office of any member of a court, but only if
the holder of the office is required to be a judicial officer or have legal
qualifications.
(2) The doctrine of incompatibility of office--
(a) does not
operate to prevent the holder of a judicial office (the
"original office" ) from being appointed to another judicial office (the
"additional office" ), and
(b) does not operate to effect or require the
surrender or vacation of the original office as a result of the appointment to
the additional office.
