The Police should have offered you the opportunity to provide a �Victim Impact Statement�. In practice they rarely do this unless prompted so you should speak to the �officer in the case� and insist that you are given the chance to provide this statement. It will be presented, by the prosecution, to the court in the event that the defendant either pleads or is found guilty.
If you do make such a statement, the police have no authority to influence what you include or what you do not include. It is YOUR opportunity to provide the Court with details of how this crime had an impact upon you. Provided it contains no lies or anything which cannot be substantiated it will be read in full.
You should also make sure that you submit a compensation schedule which should cover the sums you have had to pay out in uninsured losses. If your car was insured Third Party only it will be for the cost of replacement of the car. If your insurers are paying out for your loss, there will still be other losses such as the policy excess, any fares or car hire charges etc. that you have incurred. Unfortunately any compensation ordered is means tested by the Court so if the perpetrator has insufficient funds you will only be awarded a proportion of your losses.
Finally, bear in mind that this case will be heard at the magistrates� court. Unless a District Judge is sitting on the day (and this is unlikely) it will be heard by a Bench of three �lay� magistrates.
