Moves are under way in Malaysia that could see parts of the country implement full sharia law with inhumane punishments; there are reports that the Deputy Prime Minister could agree to support this in parliament. Currently sharia courts have limited jurisdiction in family matters, with the main criminal courts operating at federal level making decisions based on the constitution. Even this situation can create significant problems for Christians, particularly converts from Islam. Their conversion is not recognised in the sharia court system, so they are still officially Muslims. Christian women converting from Islam cannot legally marry a Christian man, as sharia forbids Muslim women from marrying non-Muslims. There have been several previous attempts to extend the jurisdiction and sentencing powers of the sharia courts, with bills that included amputation of limbs for theft and death for blasphemy and apostasy. Government can only implement this if parliament changes the constitution.
