Reasonably appropriate - the second limb
18 Notwithstanding the range of issues canvassed in the written submissions of the parties, the substance of the appeal - with respect - is to be found in the manner in which the second of the questions posed by Lange (as modified) was to be answered.
19 The primary Judge concluded that the prohibition was "reasonably appropriate and adapted to serve the legitimate ends of protecting public health, safety and amenity and preserving the ability of all members of the public to use the area": [2013] FCA 344 at [84], (2013) 210 FCR 484 at 501.
20 The "relative succinctness" of the words used in Lange, it has since been said, "should not mislead" and require "a series of different enquiries": Monis v The Queen [2013] HCA 4, (2013) 295 ALR 259 at 329. Crennan, Kiefel and Bell JJ there observed:
[279] The relative succinctness with which the test is stated in Lange should not mislead. What has been referred to as the second limb of the Lange test, read with other statements in Lange, may be seen to involve a series of different enquiries.
[280] The first enquiry concerns the relationship between a valid legislative object and the means adopted for its attainment. The latter must be "reasonably appropriate and adapted", or proportionate, to that object…
[281] Even if the ends and means of the impugned legislation are in proportion, the second limb of the Lange test requires that they each be tested for compatibility with the constitutional imperative of the maintenance of the system of representative government. It will be a rare case where a conclusion of outright incompatibility will be reached and, where it is, it will be by reference to the object of the legislation. In most cases, the question of incompatibility will involve examining the extent of the effect of the legislative restrictions upon the communications the subject of the implied freedom which supports the maintenance of that system of government.
[282] What is not clearly expressed in the second limb of the test is what appeared in the earlier statement relating to the two conditions for validity, namely that the law must also be proportionate, or reasonably appropriate and adapted, to the first object of maintaining representative government. This enquiry involves the relationship between that object and the means employed by the legislation. It is tested by assessing the extent of the restriction imposed upon political communication, the subject of the freedom…
[283] These tests or enquiries involve proportionality analysis. It was said on more than one occasion in Lange that there was no difference between the concept reflected in the words "reasonably appropriate and adapted" and the test of proportionality…: (2013) 295 ALR 259 at 329.
Hayne J had there earlier expressed the task to be undertaken as follows:
[144] If a law which effectively burdens political communication pursues a legitimate end, the second Lange question asks whether the means chosen to achieve that end are reasonably appropriate and adapted to achieving it in a manner compatible with the system of representative and responsible government. This question requires the Court to make a judgment. The judgment may be assisted by adopting the distinctive tripartite analysis that has found favour in other legal systems. On this analysis, separate consideration is given to questions of suitability, necessity and strict proportionality.
[145] But whatever structure is used for the analysis, it is necessary to consider the legal and practical effect of the impugned law. It is necessary to identify how the law curtails or burdens political communication on the one hand and how it relates to what has been identified as the law's legitimate end on the other. In undertaking that comparison it is essential to recognise that the legitimacy of the object or end of the impugned law is identified by considering the compatibility of that object or end with the system of representative and responsible government and the freedom of political communication which is its indispensable incident.
[146] It bears repeating that, because "legitimate" must be understood in this way, the comparison that is to be made between the effect of the impugned law upon the freedom to communicate on government and political matters and the law's connection with an identified end proceeds from a common point of reference: the constitutionally prescribed system of government and the freedom of political communication which is its indispensable incident. The comparison to be made does not call for the balancing of incommensurables or comparing of the incomparable, as would be the case if the comparison was between the law's effect on freedom of political communication and the law's effect on some public interest or purpose wholly unconnected with the implied freedom: (2013) 295 ALR 259 at 298 - 299.
21 When considering whether "there were other, less drastic means by which the objectives of the law could have been achieved" ((1997) 189 CLR 520 at 568, as suggested by Lange, supra) or when considering the "availability of an alternative mode of regulation" an analogy may be made to "alternative modes or regulation … to determine the existence of a prohibited purpose of discriminating against freedom of interstate trade and commerce, contrary to s 92 of the Constitution": Attorney-General (SA) v Corporation of the City of Adelaide [2013] HCA 3 at [65], (2013) 295 ALR 197 at 220 per French CJ.
22 The two principal touchstones by reference to which it was submitted on behalf of Mr O'Flaherty that "there were clearly other, less drastic means by which the objectives of the law could have been achieved" were that s 632 (or the notice) could have either:
conferred a discretion; or
provided for the granting of permission
to camp or stay overnight. The total prohibition on camping or staying overnight in Martin Place, it was said, was "disproportionate" given the ability to preserve or protect the legislative objectives by conferring a discretion to permit camping or staying overnight or by the granting of permissions to occupy the site (for example) for a specified period of time.
23 The same arguments were apparently advanced before the primary Judge. The arguments did not there meet with any success. Nor do they have any greater success on appeal.
24 It may be accepted that a notice issued under s 632(2) of the Local Government Act may well (for example) have permitted camping or staying overnight in Martin Place for a limited period or prohibited such camping or staying overnight on specified days. Had the decision been theirs to make, some judges may be more or less inclined to have themselves issued such a notice. But the power to issue such a notice is not entrusted to a Judge of this or another Court. Nor is power conferred upon a judge to invalidate a prohibition merely because the prohibition may not accord with his or her own view. The power to issue a notice is vested (in this case) in the City of Sydney. "Judicial review of legislative action, for the purpose of deciding whether it conforms to the limitations on power imposed by the Constitution, does not involve the substitution of the opinions of judges for those of the legislators upon contestable issues of policy": Mulholland v Australian Electoral Commission [2004] HCA 41 at [32], (2004) 220 CLR 181 at 197 per Gleeson CJ.
25 Although it remains the task of the Court to scrutinise the prohibition imposed and to undertake the analysis required by Lange, weight must be given in the present proceeding to the legislative judgment exercised when s 632 was enacted and when vesting in a Local Council the power to issue a notice such as that erected in Martin Place: cf. Australian Capital Television Pty Ltd v Commonwealth (1992) 177 CLR 106 at 144 per Mason CJ. When considering restrictions on broadcasting imposed by amendments to the Broadcasting Act 1942 (Cth), Mason CJ there observed:
In weighing the respective interests involved and in assessing the necessity for the restriction imposed, the Court will give weight to the legislative judgment on these issues. But, in the ultimate analysis, it is for the Court to determine whether the constitutional guarantee has been infringed in a given case. And the Court must scrutinize with scrupulous care restrictions affecting free communication in the conduct of elections for political office for it is in that area that the guarantee fulfils its primary purpose.
The task of a Court is not to form a view as to whether one legislative means of achieving a statutory objective is "slightly preferable" to another; its task is confined to determining whether the chosen legislative scheme is "unreasonably greater than is achievable by other means": Coleman v Power [2004] HCA 39, (2004) 220 CLR 1. McHugh J there said:
[100] … The constitutional test does not call for nice judgments as to whether one course is slightly preferable to another. But the Constitution's tolerance of the legislative judgment ends once it is apparent that the selected course unreasonably burdens the communication given the availability of other alternatives. The communication will not remain free in the relevant sense if the burden is unreasonably greater than is achievable by other means. Whether the burden leaves the communication free is, of course, a matter of judgment. But there is nothing novel about courts making judgments when they are asked to apply a principle or rule of law. Much of the daily work of courts requires them to make judgments as to whether a particular set of facts or circumstances is or is not within a rule or principle of law: (2004) 220 CLR 1 at 53.
26 The prohibition in the present case, it is concluded, was "reasonably appropriate and adapted to serve" the legislative objectives of s 632. Although some other form of notice may well have been issued:
the prohibition in fact imposed by s 632 and the notices in respect to camping or staying overnight at Martin Place
cannot be said to be not a reasonably appropriate course in circumstances where:
the protestors retained the freedom to otherwise occupy that site or other public sites within the City of Sydney and thereby communicate their views
The prohibition on camping or staying overnight in Martin Place left the protestors free to otherwise communicate their views.
27 The primary Judge was correct, with respect, to reach the same conclusion.
