Actually, this is also incorrect. They do not decide what the law means, there is no decision involved. They attempt, to the most exactingly precise level possible, to determine what congress intended when the law was enacted.

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
