And yes you can get charged with drink driving without being caught driving at the time. I know someone who drove home from the pub, got home ok, but had the police turn up and breathalyse him and then charge him based on evidence that he was seen leaving the pub in his car.
I was caught in a similar situation (although a more emotional and violent, long story). I admitted it, was breathalysed at the station twice over the limit and was banned for 9 months (12 months but reduced with a course). They said I could have said I wasn't driving and the state of the witnesses could have meant I may have got away with it, but such is life. You do wrong, you take it on the chin and move on.
I am however still puzzled. If I had refused to give a sample of breath or blood, I would have been banned for 6 months for that offence instead like the story in the OP? Doesn't seem right.
