Ambiguity in the law means that there is more than one meaning for the same thing. It happens when the law does not clearly say what it is supposed to do, or when the law has two meanings that don't match up. When this happens, it can be difficult for people to understand the law, or it can cause confusion in how it is applied. The courts will usually try to find a way to make the law work, but they may need more information or they might have to make a judgement to decide which meaning is correct.
