The Michigan Supreme Court sure has. Laws are based on common and case laws. They could be influenced by any case law presented. There are always 2 objecting points of laws when deciding a case and the judge picks the ones he feels is right (for him). That is biased. That sets a precedent.
Then new legislation can be introduced to make a change to the law that is existing, that is where some of the problems lie. Since many state representatives are conservative and most people don't really research their Judges but vote for the incumbent...Rogue Judges just stay in power. If someone else sees the problem and runs for the seat and loses, lets say an attorney, then his career is over in that area or county.
Of course there are strong lobby groups that influence what happens in the court room. One such group that actually sits in the court room is MADD. There was one case of a woman who after a night at the bar decided after she had gotten in her car that she shouldn't be driving so she took a nap in the back seat. To me I felt she was being very responsible, but according to the law, she had left her car keys in the ignition. When the police saw that she was asleep in the back seat but her keys were in the ignition she was arrested. She was sentenced to 6 months in jail, but with a work release and had 360 hours of community service. Now how can she work a full time job and do 360 of community service with in 6 months? Of course there's an out. She could pay the court 8 dollars an hour for each hour of community service, which of course she didn't have.
This is just one case that a law has gone awry. She is still in jail for trying to do the right thing.
It's all about money.
