Questão jurídica principal
Whether the appeal sufficiently challenged the independent alternative reasoning on adequate causation.
Decisão extraída
The appeal did not meet the Federal Supreme Court's reasoning requirement because it failed to address the adequacy reasoning, which was independently dispositive.
Fundamentação extraída
When the lower court relies on multiple independent grounds, each sufficient on its own, all grounds must be specifically challenged; here the appellant only argued natural causation and did not substantiate any legal error regarding adequate causation.
