Attorney General for NSW v MM (a pseudonym) by his tutor Barbara Ramjan

The matter before the court involved a dispute between the Attorney General for New South Wales and MM, identified by a pseudonym, represented by his tutor Barbara Ramjan. The dispute centred on the compatibility of state and federal legislation concerning the treatment and management of individuals with mental health cognitive impairments. The question before the court was whether section 138 of the Mental Health Cognitive Impairment Forensic Provisions Act 2020 (NSW) was operationally inconsistent with section 67G of the National Disability Insurance Scheme Act 2013 (Cth). The court was tasked with determining the extent to which, if at all, the state law was invalid due to this inconsistency.

The court examined the provisions of both the state and federal statutes, considering their respective scopes and purposes. It assessed whether the two laws could be reconciled and whether the state law, if operating concurrently with the federal law, could lead to outcomes that were fundamentally at odds with each other. The court took into account the broader legislative framework and the principles of constitutional interpretation to ascertain the intended operation of each law. It concluded that there was an operational inconsistency because the state law, in certain circumstances, permitted actions that were precluded by the federal law, thereby creating a conflict that could not be resolved through concurrent operation.

The court found that the inconsistency between the state and federal laws was indeed operational and could not be harmonised. Consequently, the state law was deemed invalid to the extent of the inconsistency. The decision underscored the need for careful consideration of the interaction between state and federal legislation to ensure that individuals with mental health cognitive impairments are treated in a manner consistent with the overarching legislative intent. The court's ruling provided clarity on the scope and limits of state legislation in this area, ensuring that federal law took precedence where an inconsistency was identified.
