Key legal question
Whether the alleged omission of E.'s police statement rendered the first-instance judgment null and void
Extracted holding
The complaint was inadmissible because the issue had not been exhausted before the cantonal instances; A. had also waived the defence argument earlier.
Extracted reasoning
A party cannot invoke in revision a violation of the right to be heard that was known earlier and was not challenged by available remedies. The complaint was raised for the first time before the Federal Court.
