Questão jurídica principal
Whether the objection decision was void because it was not manually signed
Decisão extraída
No. The lack of a handwritten signature is not, by itself, a particularly serious defect and does not render the decision void.
Fundamentação extraída
Social insurance decisions must be in writing, but a handwritten signature is not a statutory validity requirement. The origin of the decision was identifiable and no prejudice resulted from the omission.
