Mark Shuttleworth, a South African-born entrepreneur, emigrated in 2001. Under the Exchange Control Regulations made under the Currency and Exchanges Act 9 of 1933, his South African assets were placed in blocked accounts and could not be expatriated without permission from the South African Reserve Bank (SARB). In 2008 and again in 2009 Shuttleworth applied, through an authorised dealer bank, for permission to transfer his blocked assets abroad. SARB approved the transfers subject to payment of a flat ten per cent 'exit levy' on the value of the assets exported, imposed in terms of Exchange Control Circulars and Rulings. Shuttleworth paid a total of R250,474,893.50 under protest and challenged the levy, contending that it was unlawful, unconstitutional, and amounted to an impermissible tax imposed without parliamentary authorisation. He sought review and repayment of the levy and wide-ranging constitutional relief against the exchange control framework.
