The judge ruled that will to be invalid and she later reappointed Maryanne to a slew of Green Group companies.
Justice Winkelmann also declared Maryanne was a trustee of the Hugh Green Trust and Hugh Green Property Trust, which control the business side of the Green Group.
The judge also said that John and Frances Green — who joined company boards in the months before their sister was removed from them — were not validly appointed and are not directors of the Green Group firms.
She also removed the pair from the two trusts in question.
The decision is being appealed and as well as this, John and Frances have now made a new application to remove Maryanne from the two trusts.
Maryanne, in turn, wants a restraint on her exercising her power to vote as a trustee lifted.
This restraint was put in place in July to try avoid any further discord between the parties.
The matter came back before Justice Winkelmann today in the High Court at Auckland, with much wrangling between the two sides' lawyers about the way forward, pending the application to remove Maryanne from the trusts.
Maryanne has now agreed to not exercise her powers as a trustee until November 30, ahead of an application from her siblings to restrain her from doing so while the bid to remove her is dealt with.
