Enforcing Borders Without Erasing Humanity: Immigration Control and Constitutional Justice

There is a tension at the heart of modern democratic governance that no country has fully resolved: the tension between the sovereign right of a state to control who enters and remains within its borders, and the obligation of that same state to treat every person within those borders as a bearer of fundamental rights. South Africa is not unique in grappling with this tension. But it is unique in the particular context within which it must do so — a context shaped by a Constitution born from the struggle against dehumanization, a history of forced removals and population control, and a present defined by severe inequality and mass unemployment.

Sovereignty and Its Limits

States have always asserted the right to control their borders, and international law has always recognized that right. Sovereignty includes the power to determine conditions of entry, to regulate who may work or reside within a country's territory, and to remove those who do not meet lawful requirements. This is not contested.

What is contested — and what constitutional democracies must answer clearly — is the question of how that sovereign power is exercised. Sovereignty does not exist in a constitutional vacuum. In South Africa, it exists within a framework whose foundational value, as stated in section 1 of the Constitution, is human dignity. The exercise of state power — including immigration enforcement — must be consistent with that value. When it is not, it is constitutionally invalid, regardless of how politically popular it may be.

The Constitutional Framework

South Africa's Bill of Rights is distinctive in the breadth of its application. While some rights are expressly limited to citizens — such as the right to vote and the right to a passport — most are extended to "everyone." This includes the right to dignity, the right to life, the right to freedom and security of the person, the right to a fair hearing, and the right of access to courts.

The practical implication is significant. An undocumented Zimbabwean national stopped by police has the same right to be free from arbitrary detention as a South African citizen. An asylum seeker whose application is being processed has the right to fair administrative action in the handling of that application. A deportee has the right to legal representation and the opportunity to challenge their removal before a competent authority.

These are not theoretical rights. They have been vindicated by South African courts on numerous occasions. The Constitutional Court and the Supreme Court of Appeal have repeatedly intervened to protect the rights of migrants against state overreach — setting aside unlawful deportations, ordering the release of unlawfully detained individuals, and affirming the state's obligation to provide access to the asylum system.

Where the System Falls Short

The gap between constitutional promise and operational reality is wide. South Africa's immigration system is under-resourced, burdened by backlogs, and has historically been marked by administrative dysfunction. Asylum applications take years to process. Applicants live for extended periods in legal limbo, unable to work formally, unable to access full social services, and vulnerable to exploitation. The Refugee Appeals Authority has faced persistent backlogs that effectively deny timely resolution to those with legitimate protection claims.

This dysfunction does not only harm migrants. It undermines the legitimacy of the immigration system as a whole. When people who have genuine claims for protection cannot have those claims fairly adjudicated, and when those without valid claims cannot be efficiently and lawfully removed, the system fails on all fronts simultaneously. The result is a large population of people in irregular status — not because they chose that status, but because the system was unable to process them in any other way.

Enforcement With Constitutional Integrity

What would constitutionally grounded immigration enforcement look like in practice? First, it would mean an adequately funded and staffed Department of Home Affairs, capable of processing applications within reasonable timeframes and conducting enforcement operations with properly trained officials. Second, it would mean access to legal representation for those subject to deportation proceedings — either through state-funded legal aid or through properly resourced civil society partnerships. Third, it would mean detention used as a last resort, for the shortest necessary period, with meaningful judicial oversight. Fourth, it would mean a zero-tolerance approach to vigilante enforcement, with prosecutorial follow-through against those who take immigration enforcement into their own hands.

None of this is unaffordable in principle. What it requires is political will — a genuine commitment to doing immigration enforcement properly, rather than performing it loudly. The political temptation is always to be seen to be tough. Constitutional governance requires being lawful and fair, even when that is less visible and less popular.

The Stakes

The manner in which a state treats its most vulnerable — those without political voice, without citizenship, without the protection of powerful networks — is the most accurate measure of the depth of its constitutional commitment. South Africa has the constitutional architecture to enforce its borders with dignity and justice. The challenge is building the political will and institutional capacity to make that architecture a lived reality rather than an aspirational text.

Borders matter. So does humanity. The Constitution demands that South Africa take both seriously.
