Key legal question
Whether the factual findings on cocaine sales were arbitrarily assessed and contrary to in dubio pro reo.
Extracted holding
The complaint was inadequately reasoned and amounted only to an appellatory challenge to the evidence; it was therefore inadmissible.
Extracted reasoning
A mere disagreement with the lower court's weighing of evidence does not show manifest arbitrariness, and constitutional complaints require specific substantiation under Art. 106(2) LTF.
