Key legal question
Whether the appeal met the formal requirements of Art. 42 BGG, especially a proper request and reasoning
Extracted holding
The appeal did not satisfy the minimum formal requirements because it lacked a valid request and did not engage concretely with the cantonal court's reasoning.
Extracted reasoning
A federal appeal must contain requests and reasoning showing how the challenged decision violates law. The appellant failed to address the key finding on natural causation and did not show any legal error or relevant factual error.
