Hello all, This is about a case where my wife was accused of speeding and found the whole court process to be quite odd and surreal. I think the best way to explain it is in sequence... Oct 2016 - Wife gets a fixed charge notice saying she was doing 86 in an 80Kph zone in Aug 2016. She finds this odd as our cars inbuilt GPS is fitted with a speed warning and she knows the bypass where it happened has a reduced special speed limit, so she decides to wait for the summons and fight it. Mar 2016 Summons arrives for a Sept court date. We enter the GPS co-ordinates in the summons photos in to various mapping sites (Google, Here, Bing, and OSi) and they all show that the speed van was reporting that it was some 50 meters away from the layby in which it actually was. We feel that this calls in to question the accuracy of the speed reading. If one part of the system was so inaccurate how can we be sure the rest of it was any better? According the the US gov consumer grade GPS are expected to be accurate to 4.9m, commercial, scientific and evidence GPS systems should have much better accuracy. Sept 2016 - Case adjourned as court was backlogged. Oct 2016 - Wife states our case. Prosecuting Sargent sates "we dont use that American GPS", he asks for an adjournment and says he will download all the logs and give them to us as the next court date. Nov 2016 - Before court sits, Sargent says he has no more info to hive than what was on the summons. He gives us a Google StreetView printout of the layby which says that proves the co-ordinates are correct. I point out the co-ordinates in the printout are different to the summons, his reponce is to say "GPS is just an approximation, because the earth is round it can't be more accurate than 50 meters". I wanted to tell him he was talking nonsense as I used to write software for emergency locator beacons for Raytheon. My wife is called up. The Sargent explains his case, and he offers up the StreetView printout to the judge. My wife is asked for her side she says that she is questioning the accuracy of the equipment due to the inaccuracy of the GPS details. She offers up printouts from GPS.gov (the official GPS website) stating what the expected accuracy of various GPS devices should be as well as how GPS works. The judge refuses the printouts saying they are just hearsay and information but not evidence. She argues some more, but he repeats that he is refusing to take any pieces of paper from her. She argues the Sargent's printout is inaccurate, but the judge says she should get a certified expert to refute that. She asks if I can speak for her explaining my work history and knowledge of GPS - he refuses. Next she is fined €150 and sent on her way. So in a nutshell the whole process has left us bemused. The Garda Sargent was able to offer up printouts from Google as evidence but my wife couldn't. The Sargent had a very poor grasp of how the speed detection equipment works and the judge didn't know that GPS co-ordinates were embedded in the summons photo until my wife showed him. Part of us wants to get a solicitor involved and appeal it, but we also know that is risky as the fine can be increased. For now we are trying to work out what happened. Was due process followed? Were our maps, and printouts really not proper evidence. Basically we are confused by it all.
