One such treaty was the UN Convention on the Elimination of Racial Discrimination (CERD), which the U.S. had ratified in 1994, but (per the Supremacy Clause of Article Six of the United States Constitution, which does not permit treaties to override the Constitution) had attached a reservation that its ratification did not accept treaty requirements that were incompatible with the Constitution of the United States. The NGOs, including Human Rights Watch and Amnesty International, demanded that U.S. drop its reservations and "comply" with the treaty. The U.S. Department of State had noted specifically that CERD's restrictions on freedom of speech and freedom of assembly were incompatible with the First Amendment to the Constitution of the United States. The United States was far from the only such country to do so, however. Incompatibility of the treaty with national constitutions, including the freedoms of assembly and speech guaranteed by those constitutions, is also noted by Antigua and Barbuda, the Bahamas, Barbados, France, Guyana, Jamaica, Japan, Nepal, Papua New Guinea, Switzerland, and Thailand. Several, including France, Ireland, Italy, Japan, Malta, Monaco, Nepal, the United Kingdom, note that they consider the provisions of the treaty to be restricted by and subject to the freedoms of speech and assembly set forth in the Universal Declaration of Human Rights.
