Campaigners objecting increased parking charges said that the increases had made parking in Barnet's quiet residential streets "more expensive than parking outside Harrods" after their victory in the High Court today.
Mr Attfield said after: "Barnet Council has been caught picking the pockets of CPZ residents.
"Despite making up less than 10% of the borough, they were being made to contribute disproportionately to a range of services such as road repairs and the provision of bus passes across the borough.
"Today's judgment confirms what I have maintained all along: that Parliament never intended local authorities to take a large cut every time a book club meets, mums get together for coffee or a washing machine is repaired.
"It is regrettable that Barnet has spent over two years, and tens of thousands of pounds, standing by their charges which they should have known were legally and morally wrong."
Professor Stephen Glaister, director of the RAC Foundation, has said today's ruling quashing parking charge increases in Barnet was "fantastic news for drivers".
Mr Glaister said:
The law is explicit - parking charges are about managing congestion, not raising revenue. If there is a surplus collected, then there are strict rules on what it can be used for.
The question is: why did Barnet ever think it had an arguable case to pick on one group of residents to shoulder an additional tax?
Parking campaigners from the London borough of Barnet have won the quashing of the local council's decision to dramatically increase parking charges in April 2011.
The judge rejected arguments put forward by Barnet council lawyers that it had powers under section 45 of the 1984 Act to raise a surplus from parking charges for transport functions.
There were no parking charges in David Attfield's quiet residential road, who brought the lead case, until the controlled parking zone (CPZ) was first introduced in 2001 to prevent tube commuters parking in local streets.
- The cost of a permit for a first car was initially £20 and visitor vouchers cost 35p each.
- The charges were increased in 2006.
- In 2011 that they leapt for a first car from £40 to £100.
- Visitors' vouchers increased from £1 to £4 - among the highest CPZ charges in London.
Parking campaigners today won a landmark High Court victory against increased charges which has implications for the rest of the country.
A judge ruled Barnet council in north London acted unlawfully when it increased the cost of residents' parking permits and visitor vouchers in controlled parking zones (CPZs) to raise revenue.
The additional income was intended to meet projected expenditure for road maintenance and improvements, concessionary fares and other road transport costs.
The ruling was a victory for the Barnet CPZ Action group, made up of parents and residents from the borough, and David Attfield, who brought the lead case.

Barnet FC will play their final game at Underhill, their home of 106 years, today. A sell-out crowd is expected for the crucial match against Wycombe where the Bees need a win in their bid to avoid relegation.
The Barnet manager Edgar Davids gave a helping hand to a group of stranded fans on the M6 on Saturday. On the way back from their game at Accrington (in which Davids had been sent off), the team's bus passed a supporters' coach which had broken down.
A few minutes later, the team bus returned, picked the fans up and took them to a nearby service station where they could wait in the warm. Davids had told his players to get off the bus at the service station so it could go back to get the supporters.
The fans then got to meet and chat with the Barnet players before a replacement coach arrived to take the fans home.
