When Migration Becomes a Political Target: Xenophobia, Vigilante Checks and the Rule of Law

On any given day in parts of Johannesburg, Cape Town, or Durban, foreign nationals may be stopped on the street, asked to produce identity documents, and subjected to interrogation — not by police officers, but by members of vigilante groups who have appointed themselves as enforcers of immigration policy. This is not a hypothetical scenario. It has been a documented feature of South African public life for several years, and it raises fundamental questions about the rule of law, constitutional rights, and the dangerous space that opens when the state either encourages or fails to confront extrajudicial enforcement.

The Rise of Vigilante Immigration Enforcement

Groups such as Operation Dudula and the African Transformation Movement (ATM) have organized what they describe as community-driven campaigns to identify and report undocumented migrants. In practice, these campaigns have frequently crossed into harassment, intimidation, and outright violence. Marches have targeted informal markets, foreign-owned spaza shops, and residential areas perceived to house migrants. In some instances, foreign nationals have been assaulted. In others, their property has been destroyed.

The leaders of these groups often frame their activities in the language of patriotism and economic justice. They position themselves as filling a vacuum left by a state that has, in their view, failed to enforce its own immigration laws. This framing has proven politically effective. Several of these figures have leveraged their anti-immigrant activism into electoral politics, finding audiences among South Africans who feel economically marginalized and socially overlooked.

But popularity does not equal legality. And in South Africa, where the Constitution is the supreme law of the land, no amount of popular support converts an unlawful act into a lawful one.

What the Law Actually Permits

Under South Africa's Immigration Act, the power to enforce immigration law rests with the Department of Home Affairs and, in specific circumstances, the South African Police Service. Private individuals have no legal authority to stop, detain, question, or demand documentation from other individuals on the basis of suspected immigration status. Full stop.

A vigilante who stops a Mozambican national on the street and demands to see their papers is not enforcing the law. They are breaking it. Such conduct may constitute harassment, unlawful detention, or assault — all of which carry criminal consequences. The fact that it is rarely prosecuted does not make it legal. It makes it a law enforcement failure.

Moreover, even police officers are constrained in how they may conduct immigration checks. The Constitutional Court has been clear that arbitrary stops and searches are unconstitutional. There must be a lawful basis for any detention or demand for documentation. Random, racially or ethnically targeted enforcement operations violate both the Constitution and the Promotion of Equality and Prevention of Unfair Discrimination Act.

The State's Ambiguous Role

What makes this situation particularly troubling is the ambiguity of the state's response. On one hand, government officials have periodically condemned vigilante violence in public statements. On the other, some politicians have attended marches organized by groups like Operation Dudula, lending them a degree of legitimacy that their conduct does not deserve. In some communities, police have stood by while vigilante checks were conducted, effectively providing state cover for extrajudicial enforcement.

This ambiguity has consequences. When the state signals — through action or inaction — that vigilante immigration enforcement is tolerable, it creates a permissive environment in which further abuses become more likely. It also sends a message to foreign nationals that the constitutional protection to which they are entitled will not, in practice, be enforced on their behalf.

The Rule of Law Cannot Have Exceptions

The rule of law is not a principle that applies only when it is convenient or when its beneficiaries are popular. It is, by definition, a constraint on power — including the power of majorities to harm minorities. A society that tolerates extrajudicial enforcement against one group of people has fundamentally weakened the legal infrastructure that protects everyone.

This is not an abstract point. The mechanisms of vigilante enforcement — the profiling, the public humiliation, the implicit threat of violence — are mechanisms that can be, and historically have been, turned against any group that becomes politically disfavoured. South Africans, of all people, should understand this. The apartheid state was itself a machine for the extrajudicial enforcement of identity-based exclusion, legitimized over time by the silence and complicity of those it did not target.

Immigration policy is a legitimate subject of democratic debate. How many people should be admitted, under what conditions, with what documentation requirements — these are questions that democracies answer through legislation and policy. But the enforcement of those policies must occur within the law. When it does not — when communities take immigration enforcement into their own hands, and when the state looks away — the rule of law itself is the casualty.
