Changing the boundaries of an existing state is an action Congress can take due to its constitutional authority. The United States Constitution grants Congress the power to admit new states and make rules regarding their governance. This includes altering the boundaries of existing states, typically when state legislatures agree to such changes and upon Congressional approval.

This capability reflects the federal structure of the government, where both the states and the federal government have roles in determining state boundaries. The process often involves both state and federal legislative approvals to ensure a decision is supported by the affected parties. While altering state boundaries is not frequent, it is constitutionally permissible under the appropriate circumstances.

The other options represent actions that are either not within Congressional authority or are not typically carried out by Congress. For example, enforcing state laws is primarily a function of state governments, and Congress does not have jurisdiction over the internal workings of a state's legal system. Overruling state courts is a power that can only be exercised through higher courts and is not a direct function of Congress. Nullifying the existence of a state would require extreme measures and is not supported by the Constitution, as states retain their rights unless altered through due process.
