DNZ Property Fund lost its court action against Argosy Property Trust after Justice Raynor Asher in the High Court at Auckland rejected its case.
The two NZX listed businesses went head-to-head over holding a special meeting of investors which DNZ wanted but Argosy's independent directors rejected the idea.
The judge said Argosy had not breached its trust deed or statutory duty in failing to agree to hold the meeting.
Argosy had argued all along it did not want the event because its annual general meeting was due soon.
"The decision made by Argosy and supported by the Guardian Trust to not call a special meeting and rather to put the resolutions at the annual general meeting has not been shown to be capricious or irrational or beyond the bounds of reason.
