Key legal question
Whether the appeal introduced an impermissible new prayer for relief
Extracted holding
The prayer was admissible insofar as it merely supplemented the earlier request with the reason of acknowledgment; it was inadmissible only to the extent it broadened the request beyond the first-instance limitation.
Extracted reasoning
Adding the ground of acknowledgment did not expand the claim, but asking for a declaration of no debt at all exceeded the claim as limited before the cantonal court.
