Kouwenhoven v Minister of Police and Others

Augustinus Petrus Maria Kouwenhoven, a Dutch citizen residing in Cape Town, was convicted by the Court of Appeal of 's-Hertogenbosch on 21 April 2017 for complicity in war crimes and violations of the Dutch Sanctions Act arising from his involvement in the Liberian civil war (1997-2003). He was sentenced to 19 years' imprisonment. On 8 December 2017, he was arrested in South Africa pursuant to a warrant of arrest issued on 6 December 2017 by a magistrate in Pretoria under section 5(1)(b) of the Extradition Act 67 of 1962. The warrant was issued following a request from the Netherlands for his provisional arrest under the European Convention on Extradition. Kouwenhoven was released on bail on 19 December 2017. On 31 January 2018, he launched review proceedings challenging the validity of his arrest and the warrant, and seeking to prevent the extradition enquiry from proceeding.

• Whether officials gave a binding undertaking not to arrest Kouwenhoven and whether such an undertaking could bind the State
• Whether the undertaking, if given, invalidates an arrest pursuant to an otherwise valid warrant
• Whether the affidavit in support of the warrant application was properly attested before a fellow police officer in terms of Regulation 7 of the Justices of the Peace and Commissioners of Oaths Act 16 of 1963
• Whether the magistrate applied her mind to the issue of the warrant or merely 'rubber-stamped' it
• Whether the magistrate's failure to notify the Minister of Justice under section 8(1) of the Extradition Act invalidated the warrant

The appeal was dismissed with costs, including costs of two counsel for the first respondent and the second and third respondents jointly.

The binding legal principles established are: (1) A warrant of arrest issued in accordance with section 5(1)(b) of the Extradition Act is a judicial act that justifies the lawfulness of an arrest; the onus rests on the party challenging the warrant to show why it should be set aside. (2) A police officer implementing extradition requests under an international convention lacks authority to conclude agreements or give undertakings that would bind the State to disregard valid requests under that convention. (3) Under Regulation 7 of the Justices of the Peace and Commissioners of Oaths Act, a commissioner of oaths is not disqualified from attesting an affidavit merely because they are employed by the same organization as the deponent, provided their only interest arises from employment and in the course of duty. (4) A magistrate's failure to comply with the administrative duty under section 8(1) of the Extradition Act to notify the Minister does not invalidate an otherwise lawfully issued warrant; the duty arises from the issue of the warrant but does not affect the propriety of the decision to issue it.

The Court made several non-binding observations: (1) It expressed doubt (without definitively deciding) whether a breach of an undertaking by officials would invalidate a warrant issued by an independent magistrate who was not party to the undertaking, noting that "the worst motive does not render an otherwise lawful arrest unlawful." (2) The Court questioned the continued validity of the evidential rule excluding affidavits attested before attorneys acting in litigation, suggesting this rule is now superseded by the detailed regulations governing commissioners of oaths. The decision in Papenfus extending this exclusionary rule was criticized as lacking legal foundation. (3) The Court commented on the limits of forensic ingenuity, noting that raising numerous points subsequently abandoned stretched "the bounds of appropriate forensic procedure beyond breaking point." (4) The Court noted that while Mr. Kouwenhoven had lodged an appeal to the European Court of Human Rights regarding his conviction, that appeal did not affect the extradition proceedings.

This case clarifies important principles in South African extradition law: (1) Officials implementing extradition requests cannot bind the State through informal undertakings that would override obligations under international conventions. (2) It settles the law on commissioners of oaths in the employment context, overruling Dyani and confirming that police officers may attest affidavits of colleagues where their only interest arises from employment. (3) It distinguishes between substantive validity of a judicial act (the warrant) and subsequent administrative failures (notification to the Minister), holding that the latter does not retrospectively invalidate the former. (4) It emphasizes that challenging judicial acts requires clear factual evidence, not speculative allegations. The judgment reinforces the principle that extradition, governed by international conventions that have become South African law, must be implemented according to proper procedures and cannot be thwarted by alleged informal arrangements.
