According to the Washington Post from August 20, 2007, this is the first time in a Northern Virginia courtroom, a defendant charged with reckless driving attempted to challenge the constitutionality of the state's new abusive driver fees.
The case ended and was rather dramatic with a few legal twists and turns. The challenge was filed by attorneys of the Bose Law Firm in Arlington County. This means that the Assistant Commonwealth Attorney from Arlington County was responsible for arguing the motion. That never happened. According to the Washington Post, "Arlington prosecutors turned Mason's case over to the state attorney general's office."
There is some speculation of why the prosecutor did not want to defend the motion, but it is really irrelevant to the story. In the end, Charles Mason got off of the reckless driving charge.
It is noteworthy that the same attorneys who handled the coffee missile throwing case, got a legal victory for Mr. Mason. Bose Law Firm's Sudeep Bose and Thaddeus Furlong.
