Questão jurídica principal
Whether the appellant's right to be heard was violated by the refusal to hear his superior as witness.
Decisão extraída
No violation occurred, because the appellant failed to confirm the request in time and the authority could reasonably deem the evidence unnecessary.
Fundamentação extraída
The witness request was not properly maintained, and the decisive factual point was already established from the file; an additional oral confirmation would not have altered the assessment.
