In criminal cases, the interpretation and presentation of the evidence can in some circumstances be biased towards the prosecution and it is important in such cases that an experienced collision investigation expert addresses any potential evidence in respect of a Defendant’s version of events.

In a recent case following a conviction at Magistrates Court for careless driving, an elderly lady appealed her conviction and through her solicitor instructed one of our accident investigation experts, who reconstructed the events leading up to the collision. Our expert was able to demonstrate to the Judge that the events suggested by witnesses concerning the alleged speed of the vehicle was physically impossible.  The Judge agreed with the expert and the conviction was overturned.
