I would suggest that NC has had his (annual ?) meeting with the Liebherr sisters, as trustees.Now the club has a higher profile they have suggested others get involved to get a more rational / balanced democratic process in utilising their father's estate trust funds and running the club.
NC wants to retain his autocratic position, making all decisions, and has threatened them via the media.
I would anticipate that, if necessary, the Liebherrs have other people up their sleeve to continue their fathers legacy.
