s 121 Joining of claims
121.—(1) In proceedings under this Part where it appears to the Commissioner that there are more employees or subcontractors for labour than one having a common claim or similar claims against the same employer or person liable, it is not necessary for each of them to make a separate claim under this Part, but the Commissioner may permit one or more of them to lodge a memorandum or make a claim and to attend and act on behalf of and generally to represent the others, and the Commissioner may proceed to adjudicate on the several or joint claim of each and every such employee or subcontractor for labour. (2) Where the Commissioner is of the opinion that the interest of the employer or person liable is or is likely to be prejudiced by the non‑attendance of any employee or subcontractor for labour, the Commissioner must require the personal attendance of the employee or subcontractor for labour.
