The idea of nullification had a huge impact on states’ rights. Nullification means that a state can reject (or nullify) a law if it doesn’t like the law. It gives the states a huge amount of power. It basically means that a state action can override an action by the federal government. While this may sound like a good idea, there are problems with the concept. First, it is unconstitutional. The Constitution is very clear that federal law overrides state law. Thus, when a state nullifies a law, it is doing something illegal. This means the federal government will have to take action. No president can allow a state to reject a federal law. To do so could lead to impeachment of the president. Therefore, while the concept of nullification gives the states a huge amount of power, it is simply something that can’t happen under the Constitution.
