Where a person is receiving assistance in relation to proceedings, there shall, if he so wishes, be added after his name in the title of the proceedings the words "(assisted by the Commissioner for the Rights of Trade Union Members)".
The addition of those words shall not be construed as making the Commissioner a party to the proceedings or as liable to be treated as a party for any purpose; and the omission of those words shall be treated as an irregularity only and shall not nullify the proceedings, any step taken in the proceedings or any document, judgment or order therein.
