and held that it was sufficient to uphold the decision of the High Court.

Pursuant to Article 7(1)(b) of the Charter, every individual has the right to have his cause heard and the right to be presumed innocent until proven guilty by a competent court or tribunal. 96. The Court notes that upholding the right to a fair trial “requires that the imposition of a sentence in a criminal offence, and in particular, a heavy prison sentence, should be based on strong and credible evidence”. 39 As this Court has also held in Diocles William v.

The Court further recalls its position in Kijiji Isiaga v.

As an international human rights court, the Court cannot usurp this role from the domestic courts and investigate the details and particularities of evidence used in domestic proceedings.41 98.
