Key legal question
Whether the file was incomplete and the investigation principle was violated
Extracted holding
Any possible defect did not justify setting aside the cantonal judgment because the outcome would not have changed and the appellant did not raise the issue in time below.
Extracted reasoning
The court held that even if not all documents had been filed, the cantonal court likely would have decided the same way; moreover, the appellant had not objected during the cantonal proceedings, and the defect would not satisfy the requirements for federal review.
