Barbados and the region may have to re-look existing 'savings clauses' in their constitutions, which support colonial laws, immune from legal challenge.
Dean in the Faculty of Law at the University of the West Indies at Cave Hill Dr David Berry, says the Inter-American Court has in the past called on countries to get rid of the clause.
Savings clauses are common features of the constitutions of former British colonies.
They were included at Independence to provide continuity of the law during a transition period.
Dr Berry was speaking on the sidelines of a legal history conference jointly organised by the faculties of Law and Humanity and Education.
He says the conference combines historians and lawyers.
