There are advisory appointment bodies in New Zealand and in several of the Canadian Provinces. But they advise only in respect of appointments to courts at the District or County Court level, and not to the superior courts. From all accounts, they perform well. If that continues, then possibly their roles may be extended to superior courts. I am not aware of any plans for that.
All judicial offices are important ones.
However, the professional and community interest in an appointment is heightened when it is to a superior court. The appointment then comes in for more detailed and, often, more critical scrutiny. At this level, appointments need to be made on the best informed basis possible. That being so, it can be respectably argued that if there is to be an advisory body at all, then it should advise on these appointments. I acknowledge that my reservations about advisory bodies are to some extent based on a concern that if introduced here, they would merely reflect the overseas model.
