The principle of legality and a presumed right of free speech are not mandatory relevant considerations under s 31 of the Surveillance Devices Act 1998 (WA). The benefits of free speech are subsumed into the overall public interest assessment but carry no presumptive force, because the Act creates the opposite presumption through its general prohibition on publication. The principle of open justice does not automatically override a specific statutory scheme limiting publication of covertly recorded material. The risk of uncontrolled internet republication is a legitimate factor weighing against orders for publication under s 31.
