Experience

Representative matters

A major South African bank on its position regarding loan financing, subsequent Swaps and related reputational concerns with a particular focus on the bank’s engagements with various regulatory authorities and counterparties. The matter demonstrates our ability to advise financial institutions on high profile investigations into financing transactions involving multiple regulatory authorities, legal frameworks and legal, commercial and governance concerns.

A listed mining company pursuant to the discovery of misappropriations from a subsidiary in excess of USD44 million, including litigation to reveal an offshore structure created to conceal the proceeds of various frauds, as well as advising on the recovery of funds through asset tracing and concomitant litigation in a number of jurisdictions, including Switzerland, the Netherlands, the British Virgin Islands and Curacao.

A sovereign wealth fund in its investigation of widespread fraud and theft and advice to the client on the enforcement of various judgments to recover funds in Armenia, Bangladesh, the Democratic Republic of Congo, Georgia, India, Lebanon, the Kingdom of Saudi Arabia and the United Arab Emirates. The mandate also involved advice to the client on engagements with INTERPOL in an attempt to extradite wrongdoers to face trial.

A major international bank on the defence of a civil action against the Government of the Republic of South Africa, seeking to set aside the Government’s acquisition of certain aircraft in the Strategic Defence Package, notoriously known as the Arms Deal – a multi-billion rand acquisition project completed in 1999. The matter presents novel questions of law in circumstances where a tender is invalidated due to corruption.
