Simon, Michael and Don set up a project management company called Millennium Pty Ltd. Don is a solicitor and the constitution of Millennium Pty Ltd nominates that Don will be the solicitor for any land purchases or sales made by the company. The articles also provide that any disputes which arise between the company and its members should be first referred to an arbitrator before there are any court proceedings. After a number of years, Simon and Michael meet another solicitor who they think is more efficient than Don and they appoint him as solicitor for Millennium Pty Ltd. Don brings legal action against Millennium Pty Ltd over the matter. Advise the company as to their legal position.
