Key legal question
Whether the plaintiff's renewed action for the same amount was an abuse of rights under Art. 2 ZGB
Extracted holding
The renewed action was not abusive because the defendant showed no concrete disadvantage, no justified reliance on waiver, and no improper advantage gained by the plaintiff.
Extracted reasoning
Mere delay does not constitute abuse. Special circumstances are required, such as recognizable prejudice to the obligor or conduct inconsistent with earlier behavior. None were established here.
