Hmmm...
"Sorry officer - the reason I crashed my car into this house on this wet rainy night is due soley to the fact that I measured the tread on my tyres with the wrong guage. I thought I had one inch of tread, when in fact I had one millimetre..... I drive this old car with spats on the wheels, so it's really difficult to see if there's any tread or not. The guy I just bought it from told me the tyres were nearly new...."
So....'kin fill it up with your required fuel or until it's full - whichever comes first.
I don't subscribe to this 'we all make mistakes philosophy' when it comes to fuel. If you do make this mistake then you pay the consequences (if you survive).
This guys walks with 'no stain on his character' (CAA quote), no licence endorsement.... sheesh.
The one redeeming factor in this case is that this is one pilot who is unlikely to make the same mistake again. Of course he didn't mean to run out of fuel, but he didn't do enough to ensure a safe flight.
A PPL is a privilege to fly over anyone's house, park, kids, school, whatever. Once you prove you can't do that properly, action needs to be taken. What's happened to this guy ?
