Two Ghanaian nationals have filed a petition with the International Criminal Court (ICC) accusing South Africa of a "pattern of widespread and systematic attacks" against migrants. The filing escalates a continental diplomatic confrontation over xenophobic violence that South Africa's government has dismissed as "opportunistic." BBC

The petition was filed by Palgrave Boakye-Danquah, a former Ghanaian government spokesperson on governance and security, and Emmanuel Kotin, a counter-terrorism and security analyst. BBC The ICC has not yet commented publicly on whether it will consider the filing. BBC

South Africa's foreign ministry, known as DIRCO, responded sharply. A ministry spokesperson described the petition as "opportunistic," while affirming that South Africa remained "steadfast in maintaining the rule of law" and would ensure that perpetrators of violence are held fully accountable under the country's own judicial system. BBC BBC The government also stated it "categorically reject[s] xenophobia, racism, homophobia, and intolerance and discrimination in all their manifestations." BBC

DIRCO went further, calling for broader African Union talks on the root causes of migration across the continent. BBC

That framing redirects the conversation away from South Africa's domestic record and toward structural, continent-wide migration drivers. It positions the issue as one requiring multilateral diplomacy rather than judicial intervention.

The petition arrives amid intensifying anti-migrant mobilisation inside South Africa. Anti-migrant groups set 30 June as the deadline for undocumented migrants to leave the country. BBC The South African government says more than 53,000 foreign nationals have recently been deported or voluntarily repatriated. BBC

President Cyril Ramaphosa has acknowledged public concerns about migration but has condemned attacks against migrants, warning citizens against taking the law into their own hands. BBC His posture reflects two competing pressures: domestic constituencies pushing for stricter enforcement of immigration law, and the diplomatic fallout from attacks that have drawn condemnation across the continent.

ECOWAS, the 15-member bloc of West African nations, has condemned the reported attacks on African migrants in South Africa, singling out what it called the "despicable treatment of West African citizens." BBC The bloc's intervention adds institutional weight to what had been a series of bilateral and civil-society complaints. It also signals that West African governments are prepared to pursue collective diplomatic mechanisms rather than rely on quiet one-on-one channels.

The broader context here involves a jurisdictional question with significant precedent. The ICC operates under the Rome Statute, an international treaty that limits the Court's reach to four categories of crime: war crimes, crimes against humanity, genocide, and aggression. For the Court to act, it must also establish jurisdiction, typically through the territorial state being a party to the Statute or through a UN Security Council referral. South Africa is a Rome Statute party, which means the Court could theoretically exercise territorial jurisdiction over events on South African soil.

The critical threshold, however, is a principle called complementarity. The ICC is designed as a court of last resort: it may only act where a state is "unwilling or unable" genuinely to investigate and prosecute the crimes in question. Think of it as a hierarchy where national courts go first, and the ICC steps in only if those courts fail or refuse to do the job. Pretoria's insistence that its judicial system is equipped to handle perpetrators of violence directly engages this principle. The petitioners would need to demonstrate not merely that attacks occurred, but that South African authorities have failed in a concrete, systemic way to pursue accountability.

That is a high bar, and DIRCO's response reads as a deliberate invocation of complementarity. By asserting that South Africa remains "steadfast in maintaining the rule of law" and will hold perpetrators accountable, the government is laying the documentary groundwork for an admissibility challenge should the ICC's Office of the Prosecutor ever open a preliminary examination. Calling the petition "opportunistic" serves a dual purpose: it questions the filers' standing and timing while also signalling to the Court that the domestic system is already engaged.

ECOWAS's involvement raises the stakes differently. If West African states begin formally supporting the petition or filing their own communications under Article 14 of the Rome Statute (which permits state parties to refer situations to the Prosecutor), the political weight behind a potential preliminary examination grows substantially. A referral does not compel the Prosecutor to act, but it creates a formal record and increases the reputational costs of inaction.

South Africa's counter-proposal, routing the conversation through the African Union rather than the ICC, follows a familiar pattern in African diplomacy, where continental institutions are preferred over external judicial bodies. Whether AU-led talks on migration root causes would satisfy the underlying accountability concerns the petition raises is a separate question, and one the petitioners are unlikely to concede. For now, the filing is a proposal before the ICC, not an investigation, and the Court has given no signal of its intentions.
