Right back in april i got caught speeding doing 70mph in a 50 Got given a straight up fixed penalty but my licence numbers both on my photocard and paper licence did not match up( lost my photocard last summer and had to send off for a new one) They sent both licenses back with a refund for the fine but today i got a court summons-What's the worst i can expect?

OK got caught doing 80mph in a 50, was given a £60 fixed penalty, payed my fine and the police sent my liicence off but 3 weeks later i recived a letter in the post along with both my photocard driving licence and paper licence saying they are refunding my £60 because my numbers on the paper licence and photocard don't match up,this is because i lost my photocard licence last summer and replaced it with a new one. The letter stated nothing will happen for now but i may be issued with a court summons. Now considering i didn't kick up a fuss or contest the orignal fine i can't see why they wil issue a summons. What can i expect to happen in this case as it's baffling me.
