Questão jurídica principal
Whether the cantonal court’s factual findings on cocaine quantities and purity were arbitrary or violated the presumption of innocence.
Decisão extraída
The cantonal assessment of the evidence was not manifestly unsustainable; the presumption-of-innocence argument had no independent scope.
Fundamentação extraída
The accused and drug users spoke in grams, had no reason to inflate quantities, and the expert report did not make the court’s reliance on the mean purity value untenable.
