South Africa’s Navi Pillay Wins 2026 Nobel Peace Prize for Advancing International Justice

South African jurist Navanethem “Navi” Pillay has won the 2026 Nobel Peace Prize, recognising decades of work defending human rights and developing international legal protections against atrocities.

The Norwegian Nobel Committee announced the award on Friday, October 9, honouring Pillay “for her efforts to promote peace and international law.” Her career has taken her from representing anti-apartheid activists to adjudicating cases involving genocide and crimes against humanity.

Pillay, 85, was born in Durban to a family of Indian Tamil origin. She entered the legal profession under apartheid, when racial segregation and discrimination restricted access to education, employment and justice.

The committee linked her early defence of Nelson Mandela and other opponents of apartheid to her later work holding perpetrators of grave international crimes accountable.

In 1967, Pillay became the first woman to establish a law practice in South Africa’s Natal province. She represented anti-apartheid activists, challenged torture and helped secure rights for prisoners held on Robben Island.

After apartheid ended, she was appointed an acting judge of South Africa’s High Court in 1995. That year, the UN General Assembly also elected her to the International Criminal Tribunal for Rwanda, where she later served as president.

One of her most consequential cases involved Jean-Paul Akayesu, a former mayor prosecuted for his role in the 1994 genocide against the Tutsi in Rwanda.

On September 2, 1998, the tribunal’s three-judge chamber, which included Pillay, convicted Akayesu of genocide and crimes against humanity. It was the first genocide conviction delivered by an international court.

The judgment also established that rape and other sexual violence can constitute genocide when committed with the intent to destroy a protected group, in whole or in part. The ruling gave international courts a precedent for addressing sexual violence as a means of group destruction.

Pillay subsequently served in the International Criminal Court’s Appeals Chamber from 2003 to 2008 before becoming UN High Commissioner for Human Rights, a position she held until 2014.

More recently, she chaired the UN commission investigating the Occupied Palestinian Territory, including East Jerusalem, and Israel. In September 2025, the commission concluded that Israel had committed genocide in Gaza. Israel rejected that finding.

She currently serves as an ad hoc judge at the International Court of Justice in the case brought by The Gambia accusing Myanmar of violating the Genocide Convention in its treatment of the Rohingya. Her appointment is specific to that case.

In explaining its choice, the Nobel Committee said international legal institutions were facing growing pressure. It presented Pillay’s work as evidence of the role courts and accountability can play in efforts to resolve conflicts peacefully.
