The original Multilateral European Convention on Extradition was opened for signature by member states in September 1957; the final text was adopted at a meeting of the Council on December 13, 1957, and entered into force on April 18, 1960. In June 1969 the Council of Europe organized a meeting for the persons responsible at national levels for the application of the Convention. Recommendations from this meeting were reflected in the Additional Protocol opened for signature on October 15, 1975. A second Additional Protocol was prepared in the course of successive meetings through to March 1976. This paper reviews the provisions of the second Additional Protocol; they address the extension of accessory extradition to offenses that carry only a pecuniary sanction, extension of the Convention to fiscal offenses, judgments in absentia, amnesty, and communication of requests for extradition. The Extradition Act of 1989 is the law that governs the United Kingdom extradition arrangements. Within the Commonwealth, extradition is possible if countries have enacted reciprocal national legislation that reflects an agreed Commonwealth extradition scheme. In the case of foreign states, it is read in conjunction with any multilateral treaty.
