Questão jurídica principal
Whether the cantonal court arbitrarily treated the party's statement on waiving a reservation of later claims as only a waiver for future unknown claims, not a waiver converting the case into a full claim
Decisão extraída
The interpretation was not arbitrary; the statement clearly concerned only future, not yet asserted claims.
Fundamentação extraída
The wording and justification of the submission, assessed objectively and in good faith, showed that the reservation was abandoned only for claims not yet brought into the proceedings. An explicit and clear declaration is required for a waiver of claims.
