Questione giuridica chiave
Whether the appellant had a legally protected interest in a declaratory judgment on set-off
Decisione estratta
Yes. Because the parties disputed only the set-off issue and the appellant faced ongoing uncertainty about whether it could offset its claim against the respondent's pension claim, a declaratory interest existed.
Motivazione estratta
The lower court erred in finding it uncertain whether the appellant had already declared set-off. The record showed that set-off had been invoked earlier. Since the mutual claims were undisputed but their set-offability was contested, immediate judicial clarification would remove uncertainty affecting the appellant's freedom of action.
