13. 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 chair of the Tribunal or a member of theTribunal if the chair is unable to act, on such conditions as the chair or member fixes.
An order made under the first paragraph may be revoked by the tribunal on hearing the matter if the tribunal is of the opinion that the interests of justice will be better served by doing so.
