they'll have the last laugh when you get towed

I can't understand why you won't pay? The car was parked there. It costs money to park there and you didn't pay?
Oh right, so why did they give you a ticket? (I'm a little lost..)
However still feels they have no right to fine him :-/
I have never said this at all? Why are you making things up?
However, I don't think £70 is a justifiable fine because they have no right to "punish" me for parking there, but only charge me for the loss or inconvenience i have caused them - which in my eyes is pretty much none.
You seem deluded. To be quite honest.
The uni. is trying to punish you to make you realise that you can't go around in life thinking rules like this can just be bent or broken.
As far as i'm aware the Uni can only CHARGE me for the inconvenience they have suffered.

£20 a year for a student one, but only if your eligible
Because he isn't a permit holder and so had no actual right to park there.

Get it right.
They have no right to fine him. Only the council do.
Contravening traffic laws is illegal.
Parking in a permit only car park is contravening a contract. The validity of being able to enforce a contract via driving into a signposted area has not been proven in law. Nor has it been proven that it is a contract. Therefore these are unenforcable invoices for parking. The charge for these has been decided that they cannot be disproportionate, however. The cut off for proportionate/disproportionate is not a fixed number and relates to the cost incurred to the owner of the car park. If the parking permit is free then the cost is likely low. If no one else was prevented from parking the cost is likely low also.
Other issues:
if the signpost is not clear then you cannot enforce the "fine" - remember it is not a fine.
This is entirely a civil matter and I think is completely up to your own sense of morals. Do not park in a busy car park, do not park antisocially. If you do these two things then live with a clear conscience and with a heavier wallet.
Did I say antisocial?
