A petition signed by 25,000 people who have been involved in motor accidents was delivered to Downing Street this week.
The signatures came from people injured in car crashes. They claim they would be unable to recover compensation under the current system if the small claims limit were raised to £5,000 from £1,000 as proposed by the ABI.
According to the Motor Accidents Solicitors Society (Mass), under the proposals petitioners would have been forced to pay legal costs and would be unable to proceed with compensation claims.
Tim Gorman of Mass said: "It's clear that many claimants are totally bewildered by the hurdles in the claims process.
"Any removal of effective professional representation, whether through changes in the claims process or the raising of the current small claims limit, runs contrary to what is in the best interests of the public and what the public have told us they want to see."
