Grenada set up a Supreme Court I believe in the 1979-83 period but it
was dismantled by the US puppet government and the current elected
government hasn't changed that. Those were "special" circumstances
however. Try writing Caribbean Rights at 5 Third Ave., Belleville,
St. Michael, barbados 809-436-9456 (voice & fax) - they probably 
have a number of papers on this topic as they have been lobbying
for a Caribbean Supreme court.
