The Hague court on September 16 convicted Kosovo’s former President Hashim Thaçi of war crimes and sentenced him to 25 years in prison. The charges relate to alleged crimes committed during the Kosovo War. This is the first time in the history of international criminal justice that a former head of state has been convicted for crimes committed during the Kosovo War, carrying significant legal and diplomatic implications. The verdict could trigger chain reactions across the Balkans and beyond, touching international law, regional reconciliation, and state sovereignty.

Event Details

Details of the Verdict

The Hague court announced on September 16 the verdicts for four former high-ranking commanders of the Kosovo Liberation Army (KLA), including former Kosovo President Hashim Thaçi. Thaçi was sentenced to 25 years in prison, while the other three defendants received sentences of 22, 20, and 15 years, respectively. The court found that the defendants had committed ‘illegal detention, torture, and murder’ against Serbian civilians and opposing political figures during and after the 1998-1999 Kosovo War, in serious violation of international humanitarian law.

Thaçi’s Political Career

Thaçi was once hailed as the ‘Father of Kosovo’s Independence’ and served as the political leader of the Kosovo Liberation Army (KLA). He served as Kosovo’s Prime Minister (2008-2014) and President (2016-2020). He played a central role in Kosovo’s independence process and was regarded as a ‘founding father’ figure for Kosovo. In 2020, however, he was summoned to the Hague court to face investigation over war crimes charges and was forced to resign from the presidency.

Legal Significance of the Case

The case was tried by the Kosovo Specialist Chambers, established by the EU pursuant to Kosovo parliamentary legislation and located in The Hague. The court applied international law and Kosovo law as the basis for adjudication. This is the first time in the history of international criminal justice that a former head of state has been convicted for crimes committed during the Kosovo War, marking a landmark precedent.

Panoramic Analysis

First, a major victory for the ’no immunity’ principle in international criminal justice. The verdict once again confirms the ’no immunity’ principle in international criminal justice, that is, former heads of state cannot escape criminal prosecution by virtue of their position. This principle has been gradually established since the 1990s, including the trials of former Yugoslav President Milosevic, former Rwandan presidents, and leaders of Cambodia’s Khmer Rouge. The Thaçi case is the latest implementation of this principle and further reinforces the constraints of international law on heads of state.

Second, the Balkans reconciliation process faces new challenges. Thaçi is viewed as a ’national hero’ in Kosovo but is widely seen as a ‘war criminal’ in Serbia. The verdict may trigger strong reactions across the Balkans, deepening the antagonism between Kosovo’s Serb and Albanian communities. The Serbian government has ‘welcomed’ the verdict, while the Kosovo government has said it ‘respects but disagrees.’ This antagonism may delay the overall reconciliation process in the Balkans.

Third, the verdict may affect Kosovo’s international standing. Kosovo unilaterally declared independence in 2008 and is currently recognized by around 100 countries including the United States, United Kingdom, France, and Germany, while around 95 countries including Serbia, Russia, and China have not recognized it. The verdict may cause already-recognizing countries to reassess their positions, and may also give un-recognizing countries new legal arguments.

Fourth, the ’ex post facto prosecution’ capacity of international law is being tested. The Kosovo War occurred in 1998-1999, but the verdict was handed down in 2026, nearly 30 years later. This ’ex post facto prosecution’ model has sparked academic debate: on one hand, it embodies the belief in the rule of law that ’no matter how long it takes, justice will eventually come’; on the other hand, issues such as evidence loss and witness changes severely affect the accuracy of verdicts. How to strike a balance between ’timely justice’ and ‘verdict accuracy’ is a core challenge for international criminal justice.

Multiple Perspectives

Court Position: The Hague court emphasized that the verdict is based on ‘sufficient and convincing’ evidence, including direct testimony from multiple victims, forensic evidence, and documentary archives. The court rejected the ‘historical context defense,’ stressing that any violation of international humanitarian law should be prosecuted regardless of the perpetrator’s identity.

Serbia’s Position: Serbian President Vucic stated that the verdict is a ‘victory for justice’ and ’long-overdue fairness’ for Serbian victims and their families. The Serbian government reiterated that ’the suffering of the Serbian people cannot be forgotten’ and called on the international community to pursue further accountability.

Kosovo’s Position: Kosovo Prime Minister Kurti stated that he ‘respects the independence of the court’ but emphasized that ’the verdict should not negate the legitimacy of the Kosovo people’s pursuit of freedom.’ Multiple political groups in Kosovo expressed ‘strong opposition,’ viewing the verdict as a ‘smear on the Kosovo national liberation movement.’

US Position: The US State Department said it ’noted’ the verdict, emphasizing that ’the United States supports the rule of law and judicial independence.’ At the same time, it emphasized that the United States continues to support Kosovo’s ‘sovereignty and territorial integrity’ and hopes all parties ’exercise restraint.’

EU Position: As the funder of the Kosovo Specialist Chambers, the EU expressed ‘full respect’ for the verdict. The EU emphasized that ‘judicial independence is one of the EU’s core values’ and hoped that Kosovo and Serbia would ‘resolve differences through dialogue.’

Academic Position: International law scholars generally view the verdict as a ’landmark,’ but also point out the limitations of ’ex post facto prosecution.’ Some scholars have called for the establishment of an ’early warning mechanism’ to investigate in a timely manner during wars and avoid evidence loss.
