If it appears to the President that the treatment in respect of recognition and enforcement accorded by the court of any country to judgments given in the Superior Courts of Ghana is substantially less favourable than that accorded by the courts of Ghana to judgments of the superior courts of that country, the President may by legislative instrument order that no proceedings shall be entertained in any court in Ghana for the recovery of any sum alleged to be payable under a judgment given in a court of that country.
