I have this in the latest edition of Judicature.
The article asks (and answers) several questions about these commissions:
- Ad hoc or permanent?
- Does the commission examine judiciary compensation only or that of other branches as well?
- Is the compensation change for the judiciary only or for other branches as well?
- Is the commission’s recommendation binding?
- Could the commission recommend a diminishment?
- What should or must the commission look at?
