FAILED JUDGE = a SIT IN Judge who failed his finals to become a Full Time Judge, thus leaving him "turned down" for a Full Time or Sit In judge position. That is how I take it, this means be would no longer be able to even be a sit in judge, unless he went back to school again. Back to square one for the wanna be Judge.
What is a SIT IN judge?
From my earlier link,
"The Committee, in most cases, advises the candidates to take part in training as substitute judges for about a year. If the candidate is deemed incompetent during that training period, the appointment procedure will then cease, and if deemed eligible, the court may recommend his or her appointment to the government."
