The National Director of Public Prosecutions (NDPP) conducted an investigation into alleged corruption in the so-called "arms deal" implicating the applicants (Thint companies and Mr Jacob Zuma). In October 2001, the Mauritian Supreme Court authorized a search and seizure of premises, resulting in copies of documents being obtained by the NDPP. After Mr Zuma was charged and the criminal proceedings were struck from the roll on 20 September 2006 due to the NDPP's unreadiness, the NDPP applied on 12 December 2006 for a letter of request under section 2(2) of the International Co-operation in Criminal Matters Act 75 of 1996 to obtain the original documents from Mauritius. Levinsohn DJP issued the letter of request on 2 April 2007. The applicants challenged this decision, arguing it was unlawful and infringed their constitutional rights.
