Key legal question
Whether the cassation court committed excessive formalism or violated the right to be heard by rejecting the complaint about unsigned protocol pages.
Extracted holding
No. The court could restrict itself to the specific formal defect invoked; the missing signature on later pages was not meaningfully raised and no unconstitutional formalism was shown.
Extracted reasoning
The protocol's evidentiary function justifies strict formal requirements, but the appellant had not alleged that the recorded statements were inaccurate or that the final page was unsigned. The cassation court therefore lawfully applied the issue-raising principle.
