Key legal question
Whether the co-appellants B.________, C.________ and D.________ had standing to file the constitutional complaint.
Extracted holding
They lacked standing because they asserted only factual interests, not their own legally protected interests.
Extracted reasoning
Only the addressee of the challenged decision, A.________ AG, could rely on rights protected by law; the other appellants referred only to possible civil or criminal responsibility as board members.
