The National Director of Public Prosecutions (NDPP), in the course of investigating alleged corruption arising from the 1999 arms procurement deal, sought to obtain original documents seized in Mauritius in 2001 from premises associated with Thales and its director, Alain Thétard. Copies of the documents had already been provided to South African authorities, but the originals remained with the Mauritian authorities. After criminal charges against Jacob Zuma and the Thint companies were struck from the roll in 2006, the NDPP applied under section 2(2) of the International Co-operation in Criminal Matters Act 75 of 1996 for a letter of request to obtain the originals and authentication affidavits. The High Court issued the letter of request. The Supreme Court of Appeal dismissed an appeal against that decision. The applicants sought leave to appeal to the Constitutional Court, challenging the lawfulness of the letter of request and alleging infringements of constitutional rights.
