17 In Croome v State of Tasmania (1997) 191 CLR 119, the plaintiffs brought proceedings in the High Court for declarations that provisions of the (TAS) Criminal Code Act 1924 which prohibited homosexual acts were inconsistent with (CTH) Human Rights (Sexual Conduct) Act 1994, s 4(1). The plaintiffs had not been prosecuted for any contravention of the relevant provisions, and there was no threatened prosecution, but alleged that they had engaged in conduct which rendered them liable to be prosecuted under those provisions. The High Court held that liability to be prosecuted, quite apart from liability to be convicted on particular facts, was sufficient foundation for a justiciable controversy. Brennan CJ, Dawson and Toohey JJ said (at 127-8):
The plaintiffs plead that they have engaged in conduct which, if the impugned provisions of the Code were and are operative, renders them liable to prosecution, conviction and punishment. The fact that the Director of Public Prosecutions does not propose to prosecute does not remove that liability. Liability to prosecution under the impugned provisions of the Code will be established if the Court were to determine the action against the plaintiffs even if liability to conviction and punishment under those provisions cannot be determined by civil process. Controversy as to the operative effect of the impugned provisions of the Code will be settled and binding on the parties. The plaintiffs have a sufficient interest to support an action for a declaration of s 109 invalidity.
18 Gaudron, McHugh and Gummow JJ said (at 136):
Their Honours in In re Judiciary & Navigation Acts are not to be taken as lending support to the notion that, where the law of a State imposes a duty upon the citizen attended by liability to prosecution and punishment under the criminal law, and the citizen asserts that, by operation of s 109 of the Constitution, the law of the State is invalid, there can be no immediate right, duty or liability to be established by determination of this Court, in an action for declaratory relief by the citizen against the State, unless the Executive Government of the State has, at least, invoked legal process against the particular citizen to enforce the criminal law.
19 In the present case, the Commonwealth does not allege any breach of the licence or any clause in it, nor claim specific performance nor any injunction to enforce it or any of its provisions. It seeks only a declaration that BIS is bound by the licence, and as a result by three of the covenants in it. Nonetheless, I do not accept that such declarations if granted do not establish some immediate duty or liability of BIS. To the contrary, the declarations claimed if granted would establish that BIS was bound to perform the covenants of the licence, and therefore had particular and identifiable duties or obligations. These would be immediate duties or liabilities, in the sense of obligations immediately and presently binding on BIS, even if there is no allegation that they have been breached. It could not be said that establishing that BIS had such obligations would involved no foreseeable consequences for the parties: to the contrary, it would establish that BIS had certain obligations, and the Commonwealth corresponding rights, under the three relevant covenants; moreover, those are immediate legal consequences as distinct from merely practical consequences and involve present legal relations between the parties.
