Revising and repealing laws is a slow process that take up a lot of legislative resources. Allowing the courts to work in parallel in this way speeds up everything. If the legislature is unhappy with the decisions the court comes to, then they can go in and make changes. If they agree then they don't have to do anything and can focus on other things.
