(Supreme Court)
Congress cannot declare laws unconstitutional. The Judiciary Branch may declare a law unconstitutional only if it conflicts with some provision of the State or Federal Constitution. The Supreme Court can rule a law to be unconstitutional, but Congress, along with the States, can only amend the Constitution.
Supreme Court
The Force Bill of 1833 was not deemed unconstitutional; rather, it was a legislative measure passed by Congress to allow the federal government to use military force to enforce federal laws, particularly in response to South Carolina's nullification of tariffs. Critics argued it infringed on states' rights, but the Supreme Court did not rule it unconstitutional. The bill was seen as a means to preserve the Union and assert federal authority. Ultimately, it highlighted the ongoing tensions between state and federal powers in the U.S. government.

The Supreme Court can declare federal laws unconstitutional and state laws unconstitutional. This power, known as judicial review, allows the Court to ensure that legislation aligns with the Constitution and protects individual rights.

Jeffersonians believed that the power to strike down laws as unconstitutional should reside with the states, rather than the federal judiciary. They argued that states had the right to interpret the Constitution and could nullify federal laws they deemed unconstitutional, reflecting a commitment to states' rights and a limited federal government. This perspective was rooted in their emphasis on popular sovereignty and the belief that local governments best understood the needs of their citizens.
They are called "unconstitutional laws".
State nullification is the idea that the states can and must refuse to enforce unconstitutional federal laws.
Both the state and federal supreme courts can overturn unconstitutional state laws; the US Supreme Court is the ultimate authority on the constitutionality of federal law.
