On 11 June 2009, police officers conducted a warrantless search at a house owned by the applicant (Michael Klaas, a retired pharmacologist) in Morningside, Johannesburg. The applicant was not present; his adult son, three-year-old son and domestic worker were found there. The police seized 2,920 tablets of methaqualone and methamphetamine, chemicals, equipment used in drug manufacturing, a chemistry book with handwritten formulas for manufacturing methaqualone, and other drug manufacturing equipment. The applicant's son and nephew were immediately arrested, but the applicant was arrested months later in East London. DNA evidence linked the applicant to gloves found at the scene, and handwriting analysis linked him to the manufacturing instructions. Evidence showed he had purchased chemicals from Glass World. The applicant was convicted on 22 November 2013 of unlawfully manufacturing drugs (count 1) and dealing in drugs (count 2) under section 5(b) of the Drugs and Drug Trafficking Act. On 10 December 2013, he was sentenced to 5 years' imprisonment on count 1 and 15 years' on count 2, to run concurrently. The applicant's defence was complete denial of knowledge, claiming he did not reside at the property but only visited occasionally, and that his nephew and domestic worker occupied the house with his minor son.
