See Fair Work Act s.441
The Commission must, as far as practicable, determine an application for a protected action ballot order within two working days after the application is made.
The relevant employer generally has the right to be heard in relation to the prerequisites for the making of a protected action ballot order (specified in s.443) before the application is determined.[1]
If there is no objection to a protected action ballot order being made by the employer, the matter may be heard on the papers.
