Questão jurídica principal
Whether the commercial court violated the pleading rule or the right to be heard by relying on witness evidence about a 'single discount' and engineering services.
Decisão extraída
No violation was established; the reasoning remained understandable and the complaint lacked a substantiated arbitrariness challenge.
Fundamentação extraída
The alleged factual basis was not shown to be absent from the pleadings, and the court's reasoning, read as a whole, sufficiently explained its view of the witness evidence.
