 When Congress passes laws, they're often somewhat unclear. You don't really know what they mean. So who gets to decide what the law means? For the last several decades, the courts have said that some law that's not clear, the courts will simply agree with the government. In other words, the government says, here's what the law means. We'll agree with the government. The problem is every four years, the government changes, and they always sort of switch the positions one after the other. So Republican governance is one way, Democratic goes the other way, and so on.
