Uber-technicality in California:
In Los Angeles the Public Defender's office is challenging every single misdemeanor charge in the city. The reason for the challenges is not because people might be innocent or subject to some massive due process violation; it's because the City Attorney may not have been technically qualifed to be elected to his post. Again, there is no allegation that this has effected the bringing of and/or prosecution of misdemeanors.
Even in California no judge is biting on this red herring.
Why do you do this? It can only make your office look foolish in front of the judges and engender hostility with the attorneys you must negotiate deals with each day. And you cannot actually think that you are going to win. Well, it is California . . .
