Principles

Statutory definitions

Otsuka v Sun Pharma [2025] FCAFC 161

This case raises whether a statutory definition may change in meaning when provisions to which it relates are later amended.  Otsuka sought extension of its aripiprazole patent on the basis that other ‘pharmaceutical substances’ were disclosed in the patent specification.  A ‘pharmaceutical substance’ is defined as a ‘substance … for therapeutic use …’…

Common law

Jayasinghe v Perry [2025] VSC 751

Vacant land sold by P to J was subject to a restrictive covenant as to building height to protect ‘rather stunning views’.  After the new house exceeded the height limit by 3m, J sought to vary the covenant7.  When an issue arose on how the underlying statutory provision was to be interpreted, …

Anthony Hordern principle

FCT v Runcity Pty Ltd [2025] FCAFC 152

It was argued a consent order made under a general power to extend time for company reinstatement was invalid because specific voidable transaction provisions were the only way to extend time10.

This raised, among other things, the Anthony Hordern principle, and whether the general power to make ‘any other order’ …

Meaning of ‘institution’

Commissioner v Montessori [2025] QCA 153

A charitable trust was established to further indigenous education under the Montessori method at Cape York.  With an expansion of operations, the trustee sought charitable institution status13.  The sole question was whether the trustee, in carrying out the trust, was an ‘institution’ – answer, yes.

That term took its ordinary meaning – …

Extrinsic materials

Hvalica v Wollongong CC [2025] NSWLEC 119

This case is about the scope of extrinsic materials available in determining purpose around whether words could be read into an environmental plan4

The judge (at [58-60]) referred to the ‘liberality’ of the modern approach, and that ‘indeed any material that may throw light on the meaning’ of the instrument could …

Surplusage

Farmer v Minister [2025] HCA 38

Edelman J (at [105]) said the presumption against surplusage in statutes ‘seldom … carries great weight’7.  The corollary that all words are to be given meaning and effect therefore has a similar status.  Importantly, the presumption ‘carries almost no weight when the provision is part of a scheme of overlapping circumstances’, as …

De minimis principle

Bilal v Ampol Australia [2025] FedCFamC2G 1724

The idea that the law does not concern itself with trifling matters is frequently invoked – see Episode 33.  This case (at [91-93]) illustrates 3 things –  (1) The law as stated by Hill J in Farnell remains correct10.  (2) The principle is a rule of thumb rather than a rule …

Variation of instruments

Ziegler v FCT [2025] FCAFC 168

Section 33(3) of the Acts Interpretation Act 1901 says –

Where an Act confers a power to make, grant or issue any instrument of a legislative or administrative character … the power shall be construed as including a power exercisable in the like manner and subject to the like conditions (if any) to repeal,

Always speaking

Petersen v Argentine Republic [2025] NSWSC 1071

After Argentina’s nationalisation of energy assets in 2012, a New York judge awarded US$16b in damages to P as a dispossessed party.  When P sought to enforce judgment, Argentina said relevant process had not been validly served on it, something it said could only happen under convention procedures5

Argentina argued that, …

Re-enactment presumption

RPPL [2025] FCA 1126; Stretton [2025] VSC 589

Two cases show how the re-enactment presumption works in practice.  In RPPL, the issue was whether jurisdiction provisions in new ART legislation are to be read the same way as in the old AAT legislation8.  Given the new provisions took into account the ‘existing well-settled position’, Cheeseman J (at …
