It doesn’t matter that personal injury lawyers have a reputation for being predatory ambulance-chasers, more concerned with making a buck than with seeking justice; nor does it matter that this reputation is not entirely undeserved, even if it may get exaggerated by pop culture portrayals and the tasteless ways some injury lawyers choose to advertise their services. It is still a very bad policy idea to legally cap lawyers’ contingency fees at 15 per cent.
