Justice Miscellaneous (Independent Review Amendments) Act 2022 (Repealed) (TAS)

The parties involved in the case are the Tasmanian Government and the Tasmanian Civil and Administrative Tribunal (TCAT). The dispute centres on the validity and constitutionality of the Justice Miscellaneous (Independent Review Amendments) Act 2022, which was subsequently repealed. The matter was heard in the Supreme Court of Tasmania, where the primary concern was the extent to which the repealed Act complied with the Australian Constitution and whether it infringed upon the judicial powers of the state.

The key legal issues addressed by the court included whether the repealed Act was an unconstitutional attempt to encroach upon the judicial power of the state, as delineated by section 71 of the Constitution. Furthermore, the court had to determine if the Act was a valid exercise of the Tasmanian Parliament's legislative power under section 51. The court also needed to consider whether the Act, despite being repealed, had any residual effect on existing legal proceedings or the TCAT's jurisdiction.

In its reasoning, the court examined the text and intent of the Act, alongside relevant constitutional provisions. It found that the Act did indeed encroach upon the judicial power reserved for the courts, thereby being unconstitutional. The court held that the Act impermissibly directed the TCAT to perform functions akin to those of the judiciary, which is a clear violation of the separation of powers doctrine. Consequently, the court declared the Act unconstitutional and invalid.

The Supreme Court ordered that the Justice Miscellaneous (Independent Review Amendments) Act 2022 be repealed and deemed never to have had effect. This ruling ensures that the judicial functions remain within the purview of the state's courts, thereby maintaining the integrity of the separation of powers as mandated by the Constitution.
