Andy, they WILL summons you I reckon.

They cant make you take the witness box, so I wouldnt worry about that.

They will likely summons you for S172 Failing to Provide. This is mutually exclusive to speeding - if they cant prove driver identity, then they cant prosecute you for speeding . Same applies the other way - to get a conviction for speeding, they must be able to prove identity, and if they're saying you havent complied with S172, then they cant prove identity!!

It's one or the other

You may be lucky - the CPS dropped my case before it got to court (although I didnt use PACE). I'm now in the process of making sure they cant re-commence proceedings, then I'll be hitting them with a large costs claim

I'm sure you've read the threads on Pepipoo - just be ready for any tricks they might try, and stick to your guns. It's about time more people stood up for themselves!!!

Neil.
