I don't see a direct admission that judge's salaries come out of the fines, but a lot of other people's do.
They have probably changed the language since I read it 25 years ago.
It appears to me that if the court fund doesn't have enough money to cover salaries the judges will catch hell about their courts not keeping up with expenses.
