First, the president's only legislative power is the power of the veto. He can't sign a bill that isn't presented to him, so if congress never presents a lobbying reform bill, he never gets to sign it.

Secondly, the purpose of the judicial system is not to "legislate from the bench." It is to strike down unconstitutional legislation. Despite what some recent conservative appointees have decided their role is. Off topic, but I do find it somewhat telling that the few federal judges who think it is their moral right to legislate from the bench usually are deeply involved in right wing religion and other forms of crazy.
