An arbitration clause contained in the articles of association, which refers to a sole arbitrator disputes 'between the partners' concerning the application of the articles and the validity of resolutions adopted by the shareholders' meeting, does not extend to disputes arising among the co-owners of a company share that has passed on intestacy as to the appointment of their common representative, since such co-owners do not hold the status of partners in the technical sense and the dispute does not relate to the application of the articles as between persons who have fully assumed the status of partner.
