Judges usually don't take kindly to arguments on technicalities when the facts of the matter are clear (UPS truck, licence # and VIN matching UPS registration and ownership). I'm surprised they prevailed.
Maybe they didn't --- it was presented to me as an urban myth, and I've never really liked the idea, and it seems that instead, there is a "Stipulated Fine program", which allows large companies like UPS to waive the right to contest tickets in exchange for agreeing to pay a preset, reduced amount per offense.
