Some interesting suggestions from readers:

If the nation sees judicial review of laws as necessary, then there should be a statute of limitations on finding a law unconstitutional, say five years. If something is unconstitutional it should be obviously so and not require three generations for the court to act. It will also remove the court’s ability to engineer a society away from the public’s enacted legislation.

and from another:

How about a constitutional amendment giving the states the collective right to remove federal judges from the bench for any reason? Perhaps by a two thirds majority vote in the upper house of two thirds of the legislatures.

and this:

In Missouri there is a mandatory retirement age of 70 for all judges. This has eliminated a lot of mischief from judges that are more concerned about meeting their judge in the afterlife than following the law.

And finally:

Should there be a distinction between tenure of power and tenure of compensation? It seems to me that lifetime tenure of compensation is the key to preserving independence, but that’s a conjecture, not a statement of religious conviction.

In other words, keep paying them until they die, but take them off the bench after some period of time.
