Serious High Court dicta

Cipla Australia v Novo Nordisk [2024] FCA 1414

E86 reported on Hill v Zuda Pty Ltd, where the High Court said that it expects lower courts to follow ‘seriously considered dicta’ of a majority of that court13.  Much has been said about the outworking of this principle since it was reconfirmed in 202214.

Perram J in Cipla (at [185]), with some hesitation in a patent context, declined to follow a statement of the High Court.  This was because it was not a ‘considered obiter dictum [emphasis added]’15Queries – What counts as judicial ‘consideration’ of an issue?  When exactly is the threshold level of ‘seriousness’ met?  And does this principle invite indelicate second-guessing on the quality of High Court outputs?

This principle is from Episode 116 of interpretation NOW!
