I like the proposal to fix the term of a Supreme Court Justice to 18 years. A new Justice would be appointed every 2 years. In the event of a vacancy in the court, a new Justice would be appointed to fill the term of the vacated seat.

This would allow each President to appoint 2 Justices per term (minimum, for a 4 year term). This also allows Justices to achieve emeritus status while still able to enjoy life. Emeritus Justices may be called upon for other duties as determined by the Chief Justice.

A Justice can only serve one term.
