If the goal is to reduce the caseload in the courts, loser pays is effective. If the goal is for the reasonable access to everyone of the courts, the current system is (I hesitate to say this, but) better. I also think that when you have a class of worker(lawyers) who's job is to read/interpret/test the boundaries of/defend the law of the land, you will always find some people who figure out ways to game the system.
