The UN Convention on the Rights of the Child
The United States has signed the UN Convention on the Rights of the Child, but is one of only two UN members not to have ratified it.
The United States government played an active role in the drafting of the Convention. It commented on nearly all of the articles, and proposed the original text of seven of them. Three of these come directly from the United States Constitution and were proposed by the administration of President Ronald Reagan. On February 16, 1995, Madeleine Albright, at the time the U.S. Ambassador to the United Nations, signed the Convention. It has not so far been ratified; the United States historically has employed a cautious approach to ratification of treaties: for example, the Convention on the Elimination of All Forms of Racial Discrimination was only ratified 28 years after being signed by President Lyndon B. Johnson. Though generally supportive of the Convention, President Bill Clinton did not submit it to the Senate for its advice and consent. President Barack Obama has described the failure to ratify the Convention as 'embarrassing' and has promised to review this. The United States is the only country except Somalia and South Sudan which has not ratified the Convention.
Ratification of the UNCRC requires all states party to the treaty to submit reports, outlining the implementation of the treaty on the domestic level, to the U.N. Committee on the Rights of the Child, a panel of child rights experts from around the world. States must report initially two years after acceding to (ratifying) the Convention and then every five years.Legal concerns over ratification have mostly focused on issues of sovereignty and federalism.
