Richard Roper, 63, of Long Melford, Suffolk, was instead ordered to spend just over an hour at the back of Sudbury Magistrates' Court.
Mr Roper staged his "peaceful protest" after receiving a £30 ticket for illegally parking his car across two spaces in Sudbury.
But Suffolk Police took the matter to court to reclaim the £15 they said it would cost to process the unusual payment method.
My payment has been written on stationery which aptly reflects my feelings towards the system
District Judge David Cooper, who sniggered while listening to some of the evidence in the case, suggested the compromise punishment as a way of "clearing it all off".
Mr Roper told the judge: "This is not a case of not wishing or refusing to pay but a case of the authorities refusing to accept my payment.
"What I did here, your honour, was done in good humour.
"My payment has been written on stationery which aptly reflects my feelings towards the system which I am unfortunately forced to support through my taxes."
Afterwards, Mr Roper, a retired managing director of a pharmaceuticals company, said: "I don't consider it a punishment. It was a victory for common sense, really.
"At the end of the day, it wasn't me refusing to pay the fine. It was them refusing to accept it." (Metro.co.uk)
