Motorcycle campaigners are hoping to win a legal battle against a £1-a-day parking fee to avoid paying further motoring costs on top of their bike insurance premiums.
The High Court is due to give judgment on the legality of Westminster City Council's parking fee, after leaders of the "No To Bike Parking Tax" campaign brought their fight to court.
Campaign chairman Warren Djanogly, 47, has accused the council of going beyond its powers and claims the tax is invalid as it does not benefit traffic management.
Mr Djanogly, a management consultant and Yamaha 1300 Midnight Star rider, said donations from more than 700 people had made donations to cover the £70,000 cost of the appeal against the £1 charge.
The orders were made under the provisions of the 1984 Road Traffic Regulation Act and replaced experimental orders introduced in 2008. They came into force in January.
They impose a £1-a-day charge for motorcyclists, other than for residential permit holders.
Alternatively, motorcyclists can pay £3.50 a week, £13.50 a month, £33.50 for three calendar months, or £100 a year.
Councillor Lee Rowley, Westminster's cabinet member for parking and transportation, said: "As a council, we do not shy away from robust debate but the policy to which the protesters object is a proper decision, properly arrived at by a democratically elected authority."
