What happened

Key facts

  • Kosiah was initially sentenced in June 2021 to 20 years in prison for rape, murder and cannibalism (per democrata.es).
  • Kosiah was arrested in Switzerland in 2014 (per swissinfo.ch).

The brief

The Swiss Federal Supreme Court upheld former Liberian rebel commander Alieu Kosiah’s 20-year prison sentence for war crimes and acquitted him of crimes against humanity. The ruling preserves the prison term imposed for war crimes while rejecting the crimes-against-humanity charge on legal grounds.

The court examined whether Kosiah’s conduct during Liberia’s civil war could be classified as crimes against humanity. Swissinfo reports that the period considered for that question was 1993 to 1995.

Switzerland did not add the offence to its Criminal Code until 2011, and the court concluded that applying it to Kosiah’s conduct would amount to retroactive punishment, contrary to the principle of legality. The outlets emphasize different parts of the case.

Democrata.es describes the upheld sentence as punishment for war crimes committed between 1989 and 1996, and lists rape, murder and cannibalism among the offences included in the original sentence. Swissinfo focuses on the court’s examination of the crimes-against-humanity question and the gap between the conduct under review and the offence’s addition to Swiss law.

These accounts provide different time ranges for different aspects of the case: 1989–1996 for the war crimes, and 1993–1995 for the conduct considered in relation to crimes against humanity. Kosiah received the 20-year sentence in June 2021, according to Democrata.es. He appealed, and a lower-instance court dismissed that appeal in 2023.

The Federal Supreme Court’s ruling now leaves the sentence in force while acquitting him of the separate crimes-against-humanity charge. Swissinfo says Kosiah was arrested in Switzerland in 2014.

Its account places the ruling within a prosecution that addressed conduct during Liberia’s civil war, while the legal issue before the high court concerned whether the later-added offence could apply to that conduct. The immediate consequence is that Kosiah’s 20-year prison term remains in place for war crimes; the acquittal applies to the crimes-against-humanity charge.

The court’s decision therefore turns on the distinction between the offences and the date Switzerland incorporated one of them into its Criminal Code.

Why it matters

  • Kosiah faces a 20-year prison sentence for war crimes, including rape, murder and cannibalism as listed by Democrata.es.
  • The Swiss Federal Supreme Court’s ruling separates the war-crimes sentence from the crimes-against-humanity charge, which it acquitted him of.
  • The case turns on the timing of Swiss law: the country incorporated crimes against humanity into its Criminal Code in 2011, while the conduct considered for that charge dated to 1993–1995.

What to watch next

  • Whether the upheld 20-year prison sentence for war crimes remains in force following the Federal Supreme Court ruling.
  • How the distinction between the war-crimes sentence and the crimes-against-humanity acquittal is reflected in the final disposition of Kosiah’s case.
