This is crap. Rating judges is a horrible task because it's hard for the public to make any kind of objective decision on whether a judge is doing a good job. If you ask the public what they want from a judge, I would assume most would say: detain as many persons as possible, find as many people guilty as possible, and sentence them for the maximum possible time.

The reason judges go unopposed in elections, or get reelected until they die, is because the public doesn't have the knowledge to make informed decisions about these elections.

Not all judges are elected, of course.
