Mark Shuttleworth, a South African entrepreneur, sold his company Thawte Consulting for $575 million in 1999. In 2001, he emigrated to the Isle of Man. Upon emigration, Exchange Control Regulations blocked the expatriation of his assets valued at approximately R4.3 billion. In 2008, Shuttleworth applied through Standard Bank to transfer R1.5 billion of his blocked assets out of South Africa. The South African Reserve Bank (SARB) approved the transfer subject to payment of a 10% exit levy (R165 million), based on Exchange Control Circular D375 of 26 February 2003. In 2009, Shuttleworth sought to transfer his remaining blocked assets (approximately R2.5 billion) and paid a further 10% levy of R250,474,893.50 under protest. The levy was imposed pursuant to a 2003 Budget Speech by the Minister of Finance announcing that emigrants could exit amounts over R750,000 subject to a 10% exit charge and an exiting schedule. SARB refused to reconsider its decision, relying on regulation 10(1)(c) of the Exchange Control Regulations. Shuttleworth challenged the lawfulness and constitutionality of the levy, along with various other aspects of the exchange control regime.
