118. Cases in which the questions in dispute are substantially the same or whose subject-matters could suitably be combined, whether or not the same parties are involved, may be joined by order of the president of the Tribunal or of the vice-president responsible for the division concerned, on the conditions he fixes.
An order made under the first paragraph may be revoked by the Tribunal upon hearing the matter if it is of the opinion that the interests of justice will be better served by doing so.
