Kernrechtsfrage
Whether the cooperative had to be dissolved because membership fell below the statutory minimum of seven.
Extrahierter Entscheid
Yes. Once membership drops below seven, the cooperative no longer satisfies an essential constitutive element; dissolution is appropriate if restoring the lawful state by deadline is pointless.
Extrahierte Begründung
The minimum of seven members is a defining element of a cooperative under Art. 831 OR. Below that threshold, the entity is only formally present in the register and cannot be materially restored by court intervention. In such a case, under Art. 731b OR only deadline-setting or dissolution are relevant, and dissolution is justified when a deadline would be futile.
