Educate the public on the problem. The current laws on the books are not all bad, although many are unnecessarily vague or grant extreme latitude to judges. There are laws currently which cover fraud and perjury. They just are never applied or enforced. The current judges are not necessarily bad, just out of touch with their constituents.
Judges do read the papers.
It might be possible to target and publicized a particularly gross judge to make an example. The Rose Bird Supreme Court and Prop 13 are just two examples. This means an effort must be formed to bring the public's perception in line with reality. Most people are unaware there is a Family Court until they are thrust into it by a divorce or other action. Most people believe the US and California court systems are usually fair.
