Can Cape Town's Metro Police Legally Investigate Crime? The Constitution Says Not So Fast
By Dr Lennit Max
(Former Police Commissioner of the Western Cape)
The City of Cape Town's recent announcement that it intends establishing an investigative capacity within its Metro Police has been welcomed by many residents frustrated by high levels of violent crime and the perceived shortcomings of the South African Police Service (SAPS). At first glance, the proposal appears both practical and necessary. More investigators should mean more criminals brought to justice.
However, good intentions cannot override constitutional principles.
The central question is not whether the City should assist in combating crime, but whether it may lawfully create a criminal investigative division without the necessary constitutional or legislative authority. In my view, the answer is no.
South Africa's Constitution is clear about the role of the police. Section 205(3) provides that the objects of the South African Police Service are to prevent, combat and investigate crime, maintain public order, protect the inhabitants of the Republic and uphold the law. The Constitution therefore expressly assigns the investigation of crime to SAPS as part of its constitutional mandate.
Municipal police services occupy a different legal position. They are not constitutional police services with the same powers as SAPS. They exist solely because Parliament created them through the South African Police Service Act, and they possess only those powers specifically granted by legislation.
That distinction is critical.
Section 64F of the SAPS Act limits the functions of municipal police services to three areas: traffic policing, the enforcement of municipal by-laws, and the prevention of crime. Noticeably absent is any reference to the investigation of crime.
This omission is unlikely to have been accidental. Parliament deliberately distinguished between preventing crime and investigating crime. While Metro Police officers may patrol neighbourhoods, enforce traffic laws, conduct roadblocks and police municipal by-laws, the collection of evidence, interviewing witnesses, preparing criminal dockets, analysing crime scenes and building prosecutable cases remain functions traditionally assigned to SAPS detectives.
The constitutional principle of legality reinforces this position. Every organ of state may exercise only those powers that the Constitution or legislation confers upon it. Municipalities cannot simply assume additional powers because they believe those powers are necessary or desirable. Nor can a municipal council expand its authority through policy decisions, council resolutions or executive announcements.
Some have argued that section 99 of the Constitution provides a solution. That provision allows a Cabinet Minister to assign certain statutory powers to a municipal council. However, section 99 does not permit municipalities to appropriate powers unilaterally. Any assignment must be formal, lawful and made by the responsible Cabinet member in terms of an Act of Parliament.
At present, there is no indication that the Minister of Police has assigned SAPS investigative powers to the City of Cape Town under section 99. Without such an assignment, the constitutional gateway remains closed.
Supporters of the City's proposal may argue that effective crime prevention inevitably requires investigative capability. There is merit in the practical concern. South Africans are understandably frustrated by escalating violent crime, organised criminal syndicates and limited investigative capacity within SAPS. Communities want solutions, not legal technicalities.
Yet constitutional democracies are built precisely on the principle that public power must be exercised according to law, especially when confronting serious social challenges. Operational necessity cannot justify exercising powers that the law has deliberately withheld.
If municipal police were to embark upon criminal investigations without proper legal authority, several consequences could follow. Criminal investigations may become vulnerable to legal challenge. Questions could arise regarding the admissibility of evidence, institutional accountability and prosecutorial reliance on investigations conducted outside the statutory framework. Such uncertainty risks undermining public confidence in the criminal justice system rather than strengthening it.
This should not be interpreted as opposition to strengthening metropolitan policing. On the contrary, there may well be compelling policy reasons to expand the role of Metro Police in major cities. The reality is that organised crime has evolved significantly, and policing structures should evolve with it.
But if government believes metropolitan police services should investigate criminal offences, the proper course is legislative reform, not executive innovation.
Parliament could amend the South African Police Service Act to define investigative jurisdiction, establish oversight mechanisms, prescribe specialised training, regulate accountability and determine the relationship between Metro Police investigators, SAPS detectives and the National Prosecuting Authority. Alternatively, where appropriate, investigative functions could be lawfully assigned under section 99 of the Constitution.
Either approach would preserve constitutional legality while allowing policing policy to adapt to changing realities.
The fight against crime must remain uncompromising. But so too must our commitment to the rule of law.
South Africa's constitutional democracy demands both.
The City of Cape Town's desire to improve public safety is understandable and commendable. Nevertheless, unless Parliament amends the legislative framework or investigative powers are lawfully assigned in terms of the Constitution, the creation of a general criminal investigative capacity within the Metro Police would, in my opinion, be vulnerable to successful constitutional challenge.
The Constitution is not an obstacle to effective policing. It is the framework within which effective policing must lawfully occur.
