Zilwa v Member of the Executive Council for the Department of Transport and Public Works and Another (18320/2019) [2026] ZAWCHC 4 (9 January 2026)

Key Facts

Issues

• The court examined whether the arrest of the plaintiff by a traffic officer was lawful under section 40(1)(b) of the Criminal Procedure Act. The key question was whether the offence of exceeding the speed limit fell within Schedule 1 offences that permit warrantless arrest, and whether the arresting officer had reasonable suspicion based on credible grounds. The court found that speeding offences do not qualify as Schedule 1 offences, meaning the jurisdictional threshold for warrantless arrest was not met, rendering the arrest unlawful.
• The court determined whether the plaintiff's subsequent detention by police officers was lawful. Since the arrest was found to be unlawful, the detention automatically became unlawful as well. The court held that police officers have a discretion to refuse to accept an arrested person and exercise discretion about detention, and the failure to exercise this discretion rendered the detention unlawful. The detention was also found to be an infringement of the plaintiff's constitutional right to freedom and security of the person.
• The court determined the time of the plaintiff's arrest, which was a disputed factual issue. The plaintiff's version was inconsistent with his pleaded case and other evidence. Based on the evidence of the arresting officer and the alert photo evidence, the court found that the plaintiff was stopped between 17h50 and 18h00 on the main road, and was released at 23h50 as per the SAPD 14 Register.
• The court examined the plaintiff's claim for malicious prosecution, which requires proof that the defendant set the law in motion without reasonable and probable cause, acted with malice or animus injuriandi, and the prosecution failed. The court found that mere negligence or error of judgment does not suffice for malicious prosecution. The plaintiff failed to prove that the defendants had consciousness of wrongfulness or an improper motive, and thus the claim for malicious prosecution was dismissed.
• The Second Defendant raised a special plea of non-joinder of the National Prosecuting Authority and the Director of Public Prosecutions, arguing they had exclusive purview over prosecutions. The court held that the prosecutor's independent evaluation of the docket constitutes a new and independent decision that breaks the chain of causation. Since the prosecutor decided to withdraw the charges, the special plea of non-joinder was dismissed as the prosecutor's acts were not central to the plaintiff's claim.

Holdings

• The court granted judgment in favour of the Plaintiff for unlawful arrest and detention on 28 March 2019, awarding damages for the period between 17h50 and 23h50. The court found that the Plaintiff's arrest for exceeding the speed limit was unlawful as speeding offences do not fall within Schedule 1 of the Criminal Procedure Act, thus the jurisdictional threshold for warrantless arrest was not met. The Second Defendant's detention of the Plaintiff was also found unlawful as police officers failed to exercise their discretion to release the arrestee. The court dismissed the Plaintiff's claim for malicious prosecution as the Plaintiff failed to prove the required elements including malice and absence of reasonable and probable cause. The Second Defendant's special plea of non-joinder was also dismissed with costs.
• The trial on quantum was postponed sine die. The court determined that the Plaintiff's claim for unlawful arrest and detention was successful, finding that the traffic officer did not have lawful authority to arrest for a speeding offence that does not meet the Schedule 1 threshold of the Criminal Procedure Act. The Second Defendant's detention was unlawful as police officers failed to exercise their discretion to release the arrestee. The claim for malicious prosecution was dismissed as the Plaintiff failed to prove malice and absence of reasonable and probable cause.

Remedies

• Judgment granted in favour of the Plaintiff for agreed or proven damages in respect of unlawful arrest and subsequent detention on 28 March 2019 from between 17h50 and 18h00 to 23h50, with costs including the cost of Counsel to be taxed on Scale B.
• The Second Defendant's Special Plea of non-joinder of the National Prosecuting Authority and Director of Public Prosecutions is dismissed with costs, including the cost of Counsel to be taxed on Scale B.
• Costs awarded to the Plaintiff including the cost of Counsel to be taxed on Scale B in respect of Claim A (unlawful arrest and detention), Claim B (malicious prosecution), and dismissal of the Second Defendant's Special Plea.
• The trial on quantum is postponed sine die, meaning the assessment of damages will be determined at a future date.
• The Plaintiff's claim for malicious prosecution (Claim B) is dismissed with costs, including the cost of Counsel to be taxed on Scale B, as the Plaintiff failed to discharge the onus for proving all elements of malicious prosecution.

Legal Principles

• Arrest is a drastic measure invading personal liberty and must be justifiable according to constitutional demands. The object of arrest is to ensure attendance in court, not to punish or intimidate. An arresting officer has discretion whether to arrest, even when jurisdictional facts exist. Mere negligence or error of judgment does not suffice for malicious prosecution - consciousness of wrongfulness is required.
• The court must be satisfied on a balance of probabilities that the version of the litigant upon whom the onus rests is true. When there are two mutually destructive versions, the party can only succeed if they satisfy the court on a balance of probabilities that their version is true and accurate, while the other version is false or mistaken.
• The parties agreed that vicarious liability had been resolved, as the Second Defendant admitted that members of the South African Police Services acted within the course and scope of their employment with the Second Defendant when they detained the Plaintiff. Liability depends on who had control of the conduct complained of.
• Any act performed without a lawful source contravenes the rule of law and the supremacy of the Constitution. The doctrine of legality prescribes that power should have a source in law and is applicable whenever public power is exercised. An official performing duties must act within legal bounds (intra vires).
• The causal responsibility for prosecution lies with the prosecutor acting under the authority of the NDPP. The court held that the mere act of arresting or charging does not, on its own, amount to initiating a prosecution. A break in the causal chain occurs when the prosecutor independently evaluates the docket and exercises discretion to prosecute (novus actus interveniens).
• The onus remains on the First Defendant to justify the arrest under section 40(1)(b) of the CPA. Conversely, the Plaintiff bears the onus to prove the elements of malicious prosecution. The court emphasized that he who asserts must prove, and the party who makes an assertion must satisfy the court that they are entitled to succeed on their claim or defence.

Judge Name

Passage Text

• Mere negligence, gross negligence, or error of judgment does not suffice to meet this threshold of malicious prosecution. The Defendant must have consciously disregarded the unlawfulness of his or her conduct and proceeded to act with the intent to harm the Plaintiff by putting the criminal process in motion for an improper purpose. The intention to injure includes not only the intention to injure the plaintiff but also consciousness of wrongfulness—consciousness of the fact that the prosecution is wrongful.
• The offence of exceeding the speed limit is not a Schedule 1 offence and, therefore, the Plaintiff ought not to have been arrested. The jurisdictional factors for a section 40(1)(b) defence require that the arrestor must be a peace officer, must entertain a suspicion, the suspicion must be that the suspect committed an offence referred to in Schedule 1, and the suspicion must rest on reasonable grounds.
• An arrest is a drastic measure that invades a personal liberty, and it must be justifiable according to the demands of the Bill of Rights. The arresting officer is not obliged to arrest because he or she has discretion. It does not follow that once the jurisdictional factors are present, the arresting officer must arrest, as he is not obliged to do so. He has the discretion whether or not to exercise the power to arrest.
