1. The Office and the parties to the proceedings before the Board of Appeal other than the applicant shall lodge their responses to the application within a period of two months from the service of the application.
Article 46 shall apply to the responses.
2. The application and the responses may be supplemented by replies and rejoinders by the parties, including the interveners referred to in Article 134(1), where the President, on a reasoned application made within two weeks of service of the responses or replies, considers such further pleading necessary and allows it in order to enable the party concerned to put forward its point of view.
The President shall prescribe the period within which such pleadings are to be submitted.
3. Without prejudice to the foregoing, in the cases referred to in Article 134(3), the other parties may, within a period of two months of service upon them of the response, submit a pleading confined to responding to the form of order sought and the pleas in law submitted for the first time in the response of an intervener. That period may be extended by the President on a reasoned application from the party concerned.
4. The parties’ pleadings may not change the subject-matter of the proceedings before the Board of Appeal.
