South Africa is constitutionally obliged to ensure the effective prosecution of corruption even if the offence occurs outside of its borders, a lawyer representing the Helen Suzman Foundation (HSF) has argued.He was arguing in an application to compel Justice Minister Ronald Lamola to give effect to his predecessor's decision to extradite Mozambique's former finance minister Manuel Chang to that country."Under the Constitution and relevant case law, South Africa has extraterritorial obligations that it must adhere to when deciding whether or not to extradite a person charged with corruption to a specific country," advocate Max Du Plessis SC argued in the Gauteng High Court in Johannesburg on Wednesday."South Africa's commitment requires that when making a decision to extradite, the country to which the person charged with corruption will be extradited, has the necessary will and ability to prosecute the crime properly and successfully."Chang faced extradition requests from both the US and Mozambique - where he enjoyed automatic immunity as a lawmaker - until it was lifted in January.Former Minister of Justice Michael Masutha decided on May 21 to have Chang extradited to his home country, Mozambique - not the United States.In his reasoning he cited that "the interest of justice will be best served by acceding to the request by the Republic of Mozambique".READ | Manuel Chang to be extradited from SA to Mozambique, not USMasutha's decision followed the Kempton Park Magistrate's Court's ruling on April 8 that Chang should be extradited to the US on fraud-related charges.Chang is wanted by the US in connection with allegations of conspiracy to commit fraud and taking millions of dollars in bribes in a $2bn loan scandal, News24 previously reported. #ManuelChang : Chang was arrested on December 29 in South Africa.

The fact that this was not done renders the decision to extradite unlawful, irrational and unconstitutional," Du Plessis said.The matter continues.
