Background

The Supreme Court of Tasmania has clarified the Tasmanian Civil and Administrative Tribunal’s (TASCAT) authority to extend the time for objecting to a bill of costs under the workers compensation scheme. The Court’s decision also provides important guidance regarding the scope of this power.

The Case: Walker v Mondelez Australia Pty Ltd [2026] TASSC 6

In this matter, the Supreme Court was asked to consider whether TASCAT could extend a 14-day time limit stipulated in regulation 16 of the Workers Rehabilitation and Compensation Regulations 2021 (Tas). This regulation provides that, if no objection is filed within the prescribed period, a bill of costs is deemed to be admitted.

The Arguments

The worker had contended that regulation 16 was mandatory and left no room for an extension. However, TASCAT found that it possessed the power to extend the time limit under rule 11 of the Tasmanian Civil and Administrative Tribunal Rules 2021 (Tas), which allows the Tribunal to extend or abridge time limits. The worker appealed the decision to the Supreme Court of Tasmania, arguing that TASCAT was wrong to decide that it had thepower to extend time.

The Supreme Court’s Decision

On appeal, Chief Justice Shanahan confirmed TASCAT’s decision. His Honour held that rule 11, made under section 115 of the Tasmanian Civil and Administrative Tribunal Act 2020 (Tas), grants TASCAT a broad discretionary power to extend time limits imposed by a “relevant Act”, including the Workers Rehabilitation and Compensation Act 1988 (Tas), even if the statutory period has expired. Regulation 16 deals with steps taken within ongoing proceedings before TASCAT and therefore falls within the Tribunal’s power to extend time.

Nature of Regulation 16 and the Power to Extend

The Court confirmed that regulation 16 remains a mandatory, deeming provision as had been found in prior cases. However, this does not preclude the availability of discretionary relief in suitable cases. The power to extend time, when properly interpreted, does not compromise the efficiency of the workers compensation scheme.

Distinction Between Types of Time Limits

Addressing concerns raised by the worker about the impact of the extension power on the efficient operation of the workers compensation scheme, Chief Justice Shanahan drew an important distinction between:

• time limits governing the commencement of proceedings, and
• time limits governing acts taken in relation to existing proceedings.

It was held that rule 11 applies only to the latter category. Rule 11 does not provide TASCAT with the power to extend time limits that govern the making of compensation claims or the commencement of proceedings in TASCAT.

Significance of the Decision

This decision provides valuable guidance for parties involved in workers compensation disputes. It confirms that strict procedural time limits continue to apply but that there is scope for extensions of time in relation to certain time limits within TASCAT proceedings so that unjust outcomes can be avoided.
