In the above-mentioned cases, the parties agreed to stay the proceedings without obtaining the agreement of the Tribunal. In these circumstances, it may be more common to accept an extension of the time limit for service of claims.

(b) subject to paragraph (2) are served on the defendant by the plaintiff within fourteen days of service of the application form.
