Supreme Court held that a mandatory share purchase clause is valid even if it forces a member to buy shares when their turnover increases.

The Supreme Court upheld the validity of a cooperative's bylaw requiring members to purchase additional shares when their annual turnover exceeds a specific threshold. The plaintiff argued that such a mandatory purchase clause violated their freedom of contract and property rights under the Act on Cooperatives. The court ruled that the clause was a legitimate contractual obligation designed to maintain the cooperative's capital structure and was not an unlawful restriction on the member's rights.
