Final one from me on this topic.
Went to court this morning. Due to a monumental cock-up between the MOD Police and the CPS, there was no prosecutor there to prosecute me. We were very close to having the case thrown out there and then, but the magistrates told us to come back at 2pm.
Had a nice pub lunch and went back, was in by 2:10 because a prosecutor actually turned up. Then it took 20 minutes for them to work out the maximum penalty they're allowed to give for this offence, which was quite embarrassing for them, especially when they were checking (I kid you not) Wikipedia for the info.
When it all started, the prosecutor did his bit, then my brief did his bit (he did a cracking job). When all was said and done, they gave me a £35 fine and no court costs because they'd messed up in the morning. I do have other costs such as solicitors fees and I also have to pay some compensation to the MOD (which I'd already agreed to pay).
So yeah, my record will say a £35 quid fine in magistrates court.
