I see this all the time too.. it sucks!

In traffic court, Judge William Young has been making good on the threats by routinely siding with police officers in disputes and imposing fines of up to $500 on anyone who challenges a moving violation ticket, no matter how minor, and loses. Those who pay without going to court do not face this extra fine.

"Unfortunately what you have happen a lot of times is that judges aren't particularly worried about whether what they're doing may be violating the law as the odds of someone ever appealing a $400 traffic ticket is remote," Ogden wrote. "I see it all the time. Trial judges flouting the law knowing they are unlikely to ever be challenged on an appeal because the litigants can't afford it."
Anyone who thinks suing/challenging the courts is simple, you've a lot of spare cash. ;)
