Questão jurídica principal
Whether the mutation protocols had to be personally signed by the engineer-surveyor
Decisão extraída
Yes. The law required the responsible engineer-surveyor's own handwritten signature; a facsimile stamp was not sufficient.
Fundamentação extraída
The relevant regulations required the document to be signed by the competent patent-holding engineer-surveyor, and a signature must be handwritten unless a contrary trade usage exists, which was a fact issue not reviewable in cassation.
