Key legal question
Whether the information claims were time-barred under German limitation law and when the limitation period began.
Extracted holding
The appellants had sufficient knowledge by 2003 to bring a reasonably promising action; the limitation period began at the end of 2003 and expired at the end of 2006.
Extracted reasoning
Under § 199(1) no. 2 BGB, knowledge of the facts giving rise to the claim is enough; an actual need or external compulsion to sue is not required. The appellants' reliance on the later letter from B.________ did not change the start of limitation.
