This power includes the power to interpret the basic laws of Hong Kong and Macau, the constitutional documents of the two special administrative regions which are common law and Portuguese - based legal system jurisdictions respectively . This power is a legislative power and not a judicial one in that an interpretation by the NPCSC does not affect cases which have already been decided . </P>
