Could people sue the courts for unfair treatment / economic discrimination>?

Question by Phonebreaker: Could people sue the courts for unfair treatment / economic discrimination>?
I know a guy in LA who has had a clean record all of his life. I was in the Marine Corps with him. One night not to long back he got drunk as hell at his house, ended up in an argument with his wife and slept it off in his car in his driveway. He didn’t drive at all. at about 9 am the cops pull him from the car and haul him off to jail for Operating under the influence and he gets 30 days in jail and 300 hrs community service. Now Lindsay Lohan gets 3 drunk driving offences, 2 cocaine possessions all within a two year period and gets one day in jail and probation? How is this constitutionally fair? The LA county Sheriff states Lohan got the same treatment as far as jail time everyone else gets but that’s total BS. Can he sue?
