Bo: The legal implementation date is clearly stated in all such International Conventions: it's the actual date of Ratification (which is usually declared to be one, three or six months after the deposit of the Instrument of Ratification - in this case with UNESCO). However, the international code on the Ethics of Acquisition adopted by the International Council of Museums (ICOM) in 1971 urged all museums to respect and apply the principles of the 1970 UNESCO Convention immediately in relation to their acquisitions, whether or not their countries had formally ratified the Convention - i.e. they should (voluntarily) not acquire material suspected of having been illegally or clandestinely exprted or imported after 1970. Many museums started including such a provision in their own acquisition policies and codes more or less immediately. A national example was the joint Declaration of the British Museum, Museums Association and British Academy of 1972 in the case of the United Kingdom's museums - even though the UK Government has never formally ratified UNESCO 1970. (This is now promised - at long last - for July 2002). The date of signature of an international treaty can however be significant at the government level in one very specific respect. Under the 1969 Vienna Convention on the Law of Treaties, though they are not bound to proceed to ratification and implementation, signatory countries may not take action which would frustrate or block the implementation or application of that measure by other countries. (I understand that it is because of this that the United States gave formal notice a few weeks ago of the USA's withdrawal of the Clinton Administration's signing of the Statutes of the International Criminal Court, because it has been decided to actively fight the establishment of the International Criminal Court, e.g. by putting political pressure on countries not to use or cooperate with the Court.)
