(1) A dependent of a deceased workman may apply to the Commissioner for the issue of an order to deposit compensation in respect of the death of the workmen. Such application shall be made in Form G.
(2) If compensation has not been deposited the Commissioner shall dispose of such application in accordance with the provisions of Part V of these rules:
Provided that:
(a) the commissioner may, at any time before issues are framed, cause notice to be given [through a process server or through registered post] to all or any of the dependants of the deceased workman who have not joined in the application, requiring them, if they desire to join therein to appear before him on a date specified in this behalf.
(b) any dependant to whom such notice has been given and who fails to appear and join in the application on the date specified in the notice shall not be permitted thereafter to claim that the employer is liable to deposit compensation unless he satisfies the Commissioner, that he was prevented by any sufficient cause from appearing when the case was called on for hearing.
(3) If, after completing the enquiry into the application the Commissioner issues an order requiring the employer to deposit compensation in accordance with sub-section (1) of Section 8, nothing in sub-rule (2) shall be deemed to prohibit the allotment of any part of the sum deposited as compensation to a dependant of the deceased workman who failed to join the application.
