Is it legal for a judge to give credit if a person attends the judge's church and participates in the judge's class?

Several months ago during a state trooper road block, a young man that I know was told that he was too drunk to drive and had an open container in his vehicle. He was given a ticket, taken to jail, and subsequently has gone to court. No record can be found of a rating on a breathilizer (?) test supposedly given during the stop. During the time before court, the state trooper contacts him at his place of employment and tells him that if he attends the state trooper’s church, the state trooper will fix the ticket. The young man refuses because he feels that his infringes upon his rights. BY THE WAY, the young man does not drink, cannot drink due to medication he takes, and the open container was an ice chest in the back of a pickup truck that had no openings to the back from the cab. In few words, he would have had to get out of the truck and open the ice chest to even get anything out. He has now been ordered to go to DRUG court (he has not taken any illegal drugs but is on medication and took his medication in for the judge to see) and is being penalized because his drug screens show up as having drugs in his system. The judge not only will not take into consideration that he is on prescribed medication but he also told him that if he attends the judge’s church he will be given a lighter sentence. Is this constitutional or is it just trumped up charges to make money for the courts?
