It's because it is an incredibly heavy workload. I wouldn't ask my administrative judges or my members to keep that rhythm up too long. I have members who have heard over 800 cases this year. The work these people have put in is absolutely astonishing. It is incredibly impressive.
By law, there is a maximum of 29 permanent members. You can have as many temporary members as you wish.
Ultimately, I think the way to approach the appointments is to make sure that the individuals come on board for at least two years, and then they could proceed to a three-year appointment. Finally, I would top it off with a four-year appointment, so that the individual serves for a total of nine years on the board. I think that would be the ideal mini-career plan.
It shuts off the circle of the selection process. The individual can count on a mini-career in the job, where he'll be interested in improving himself in training and do even better at what he does.
