What are the grounds upon which the court may rule a claim inadmissible due to lack of legal standing?

The court may rule a claim inadmissible due to the plaintiff's lack of existing legitimate interest, when it finds that the interest in the subject matter of the claim, such as demanding the registration of shares and proving partnership, is confined to the original contracting parties (the seller and buyer of the shares) and does not extend to other parties, such as the manager of the commercial entity, unless they prove a direct and independent interest.
