My question involves a traffic ticket from the state of: Narnia
This does not involve myself. A friend of mine received a ticket recently (claims was not speeding). This person also has a GPS device at all times on when driving. There is a way to download this information sort of like an aircraft "black box". They plan to dispute the speed via the GPS readout corresponding to the time on the ticket. Now, it probably will not be accepted in court unless sent directly from the GPS company and they are looking into doing that. Also, speed can greatly change within seconds and they are aware of this. The GPS system shows your exact speed for a particular timeframe and they think it's worth a try. It's also supposed to be accurate, but I'm sure like anything else this can be disputed. The device claims accuracy to +/- .01mph. Significantly better than the Ultralyte's +/- 1mph. This information is readily available online.
Knowing traffic courts, it will be difficult, especially considering it is in favor of the defendant. It brings into question judicial notice as well. I told them since LIDAR does not have judicial notice in this particular state (Only NJ does) it would be unconstitutional to allow the state's evidence (without judicial notice) and not your own evidence (also without judicial notice). In other words, if the LIDAR is allowed, the GPS data should also be allowed if sent directly from the manufacturer.
My question, has anyone ever heard of this being done as a viable defense?
