Questão jurídica principal
Whether the appellate judgment violated the right to be heard by insufficiently reasoning the applicable tariff for the event.
Decisão extraída
The reasoning was sufficient under Article 29(2) of the Constitution because the judgment clearly showed that the court relied on the GT K tariff and why it considered the event to fall under it.
Fundamentação extraída
A court need not address every party argument in detail; it must only state the essential considerations. The cantonal court explained that the event was a concert-like performance and that the parties had contractually agreed to account under GT K, which made clear why a GT Hb approach was rejected implicitly.
