A new report from Dublin City Council says motorists in the capital should face a 60% increase in clamping charges.

The report from the council's parking appeals officer says the €80 charge has not been increased since it was introduced in 1998.

Appeals officer William Keilthy says this means that the charge has decreased by 25% in real terms, despite the fact that the cost of petrol has doubled during the period.

He states that based on the €7 million cost of the enforcement service, the clamp release fee should be a minimum of €130.

"By keeping the charge at 1998 levels compliant motorists who pay for their parking are effectively subsiding non-compliant motorists to the tune of €50 per clamp," he states.

Mr Keilthy's report is due to be discussed at the council's transport committee meeting next Wednesday.

It reveals that clamping appeals have increased by just under 50% since 2007, which it links to the recession and greater awareness of the appeals system.

Over 55,000 motorists were clamped in Dublin city last year, usually for failing to pay and display and 95% of them accepted the fee.

Of those who appealed to the enforcement company, Dublin Street Parking Services, 656 or 22% of cases were successful and obtained a refund last year.

Gardaí are exempt from parking regulations and get a full refund and tourists are normally granted a refund as a goodwill gesture.

It found that signage concerning clearways, taxi ranks and loading bays and road markings were a significant source of complaint.

In one case, a motorist questioned whether the double yellow lines she was clamped for were legitimate.

On investigation it turned out a builder had painted them on the road for his own convenience and she received a full refund.

If an appeal is turned down a motorist can make a second stage appeal to the independent appeals officer and 105 of these, or 17%, were accepted.

The report also says that where a motorist made a valid effort by buying a ticket or had a valid permit but failed to display properly, a 50% refund is given as a gesture of goodwill.
