Key legal question
Whether the cantonal court made a manifestly inaccurate factual finding by stating that the trafficking involved 1,600 grams of heroin.
Extracted holding
The quantity was calculated incorrectly, but the error was too small to affect the sentence.
Extracted reasoning
Even using the lower quantity of 1,450–1,500 grams, the pure heroin amount differed by less than 10 grams; that difference was immaterial for sentencing given the overall seriousness of the trafficking.
