and\n\t(b)\tthe time at which the assembly will convene and the time at which it will disband; and\n\t(c)\tthe place in which the assembly will be held, and the boundaries of the area to be occupied by the assembly, or if it is to move in procession, the route that it will follow, the extent to which it will occupy the public places through which it will pass, the places (if any) at which it will halt and the time for which it will remain stationary in each such place.\n\t(2)\tThe notice must also contain the following information:\n\t(a)\tthe name and address of the person by whom the notice is given; and\n\t(b)\tthe name of the person or body of persons by whom the assembly is being, or is to be, organised; and\n\t(c)\tthe purpose of the assembly; and\n\t(d)\tan estimate of the number of persons who will participate in the assembly.\n\t(3)\tThe proposals and information must be given with as much particularity as is reasonably practicable.\n\t(4)\tThe notice must be served personally or by post, at least four days before the date of the assembly on—\n\t(a)\tthe Chief Secretary; or\n\t(b)\tthe Commissioner of Police; or\n\t(c)\tthe clerk of the council for the area in which the assembly is to be held,\nand the recipient of the notice must forthwith inform the other persons referred to in this subsection of the contents of the notice.\n\t(5)\tWhere two or more notices are given under this section in respect of the same assembly—\n\t(a)\tonly one of those notices shall be valid and effective for the purposes of this Act; and\n\t(b)\tthe Chief Secretary shall determine finally and conclusively which of the notices is to be valid and effective for the purposes of this Act.\n\t(6)\tAn objection may be made by or on behalf of the Chief Secretary, the Commissioner of Police or the council referred to in subsection (4) of this section to any proposal contained in a notice under subsection (1) of this section on the ground that it would, if effectuated, unduly prejudice any public interest.\n\t(7)\tAny such objection must set forth the grounds upon which the objector alleges that the proposal would unduly prejudice the public interest.\n\t(8)\tA copy of the objection—\n\t(a)\tmust be served at least two days before the proposed date of the assembly upon the person by whom the notice of the assembly was given; and\n\t(b)\tmust be published at least two days before the date of the assembly—\n\t(ai)\ton a website determined by the Minister; or\n\t(i)\tin a newspaper circulating generally throughout the State;

or\n\t(b)\tmay approve any other proposals submitted to him before, or at the hearing of, the application.\n\t(3)\tProceedings under this section may be heard and determined by a Judge without formality.\n6—Exemption for participants acting in accordance with approved proposals\n\t(1)\tWhere the conduct of an assembly conforms with approved proposals, a person participating in the assembly—\n\t(a)\tmay, in accordance with the proposals, position himself, or proceed over, any portion of a public place defined or described in the proposals; and\n\t(b)\tin acting in conformity with the proposals does not incur any civil or criminal liability by reason of the obstruction of a public place.\n\t(2)\tAn act permitted by this section is lawful notwithstanding the provisions of any other Act or law regulating the movement of traffic or pedestrians, or relating to the use or obstruction of a public place.\nLegislative history\nNotes\n\t•\tFor further information relating to the Act and subordinate legislation made under the Act see the Index of South Australian Statutes or www.legislation.sa.gov.au.\nPrincipal Act and amendments\nNew entries appear in bold.\nYear\nNo\nTitle\nAssent\nCommencement\n1972\n28\nPublic Assemblies Act 1972\n6.4.1972\n13.4.1972 (Gazette 13.4.1972 p1430)\n2019\n25\nStatutes Amendment and Repeal (Simplify) Act 2019\n3.10.2019\nPt 38 (s 80)—3.10.2019: s 2(1)\nProvisions amended since 3 February 1976\nNew entries appear in bold.\nEntries that relate to provisions that have been deleted appear in italics.\nProvision\nHow varied\nCommencement\ns 2\nomitted under Legislation Revision and Publication Act 2002\n\ns 4\n\n\ns 4(8)\namended by 25/2019 s 80\n3.10.2019\n","sortOrder":0}],"analysis":{"flash_summary":{"complexity_score":4,"scope_assessment":{"changed":false,"description":"The Act remains focused on the single aim stated in its long title: providing for orderly conduct of assemblies and processions in public places.

(s 4)\n- The notice must state date, start and end times, precise place or route and boundaries, pauses/halts and durations, organiser name and contact, purpose of the assembly, and an estimate of numbers. Notices must be as particular as reasonably practicable. (s 4(1)–(3))\n- If more than one notice is given for the same assembly, only one operates under the Act and the Chief Secretary decides which. (s 4(5))\n- The Chief Secretary, the Commissioner of Police or the local council may object to any proposal on the ground that it would \"unduly prejudice any public interest.\" The objection must explain the grounds and must be served and published at least 2 days before the assembly. Publication can be on a Minister-determined website, in a State-wide newspaper, or otherwise so that it likely reaches intended participants. (s 4(6)–(8))\n- A person who wishes to participate despite an objection may apply to a Judge of the Local and District Criminal Court. The Judge can quash the objection, approve the proposal, or approve alternative proposals. Proceedings may be run without formal court procedure. (s 5)\n- Where an assembly is carried out in accordance with approved proposals (either unobjected notices or Judge-approved), participants may occupy the described public place or route and, while doing so in conformity with the proposals, incur no civil or criminal liability for obstructing the public place. This legal protection operates despite other laws regulating traffic, pedestrians or obstruction. (s 6)\n\n**Who it affects\n\n- Organisers or intended participants of public assemblies (s 3: \"assembly\").\n- State actors charged with public-order oversight: the Chief Secretary, the Commissioner of Police and local councils (s 4(4), (6)).\n- Judges of the Local and District Criminal Court who hear applications under the Act (s 3: definition of \"Judge\"; s 5).\n- Members of the public and businesses who use or rely on public places that may be occupied or obstructed by assemblies.\n\n**Why it matters (official purpose, then practical implications)\n\n- Officially, the Act provides a framework for the \"orderly conduct of assemblies and processions in public places.\" That is implemented by requiring notice, enabling administrative objections on public‑interest grounds, and creating a simple court review mechanism. (Long title; ss 4–6.)\n\nPractical implications and trade-offs\n\n- Who pays and who decides: organisers bear the compliance cost of preparing and serving a detailed notice within the time limits (s 4). The Chief Secretary, police and councils can object and thereby restrict proposals (s 4(6)–(8)). The Chief Secretary also has final administrative authority where multiple notices are filed (s 4(5)). A Judge can resolve disputes on a quick, informal basis (s 5).\n- Incentives and behaviour changes: because conformity with approved proposals grants immunity from civil and criminal liability for obstruction (s 6(1)–(2)), organisers are incentivised to follow the notice process and secure approval or avoid objections. Opposing parties (police, councils) are incentivised to raise timely, specific objections when public‑interest concerns exist.\n- Costs and burdens: organisers face time and information costs (4 days' notice, particulars, service) and the administrative risk that another notice may be chosen as the valid one (s 4(5)). Police and councils must assess proposals quickly and, if objecting, prepare and publish reasons at least 2 days before the event (s 4(7)–(8)). Businesses and commuters bear the risk of temporary obstruction; participants acting within approved proposals are shielded from liability but third parties may experience disruption (s 6).\n- Discretion and legal uncertainty: key standards are open-textured—\"unduly prejudice any public interest\" and \"as much particularity as is reasonably practicable\"—so decisions by officials or judges will turn on fact-specific judgment calls (s 4(6), s 4(3)). The Act also gives the Minister the ability to choose a website for publication, introducing an administrative element to how objections reach participants (s 4(8)(ai)).\n- Interaction with other laws and private activity: the exemption for participants (s 6(2)) expressly overrides other laws regulating traffic or obstruction when the assembly conforms to approved proposals. That changes enforcement incentives for traffic laws during approved assemblies and can affect private businesses and local traffic flows; it does not itself create financial compensation or mitigation obligations for affected businesses.\n\n**Net effect in plain terms\n\n- The Act creates a short-notice administrative regime: notify 4 days ahead, objectors must act within 2 days, and an informal court route exists to resolve disputes. Following the approved plan protects participants from liability for occupying public places, while government actors retain the power to block or modify proposals on public‑interest grounds.

It creates a \"notice and approval\" process that protects organisers and participants from being charged with blocking traffic or obstructing public places—**provided they follow the rules**.\n\n**Who it affects:**\n\n- **Protest organisers and participants** – anyone planning a rally, march, or public gathering\n- **Police and local councils** – they receive the notices and can object if they think the event would harm the public interest\n- **The Chief Secretary** (a senior government official) – coordinates between agencies and decides which notice counts if multiple ones are submitted\n- **Judges** – can override objections and approve proposals that have been blocked\n\n**How it works:**\n\n1. **Give notice:** If you're organising an assembly, you must give at least **4 days' notice** to the Chief Secretary, Police Commissioner, or local council. The notice must include details like date, time, location, route (if marching), purpose, and expected crowd size.\n\n2. **Objections:** Police or council can object if they believe the event would \"unduly prejudice any public interest.\" They must explain their reasons and publish the objection (including on a government website) at least 2 days before the event.\n\n3. **Going to court:** If there's an objection, organisers can apply to a **Judge** (specifically a Judge of the Local and District Criminal Court) to have the objection quashed or to get alternative proposals approved. These hearings are informal.\n\n4. **The payoff:** If your proposals are \"approved\" (either because no one objected, or a Judge overruled the objection), participants get a **legal shield**: they can't be sued or prosecuted for obstructing public places or blocking traffic while acting according to the approved plan.\n\n**Why it matters:**\n\nThis law strikes a balance between **free assembly** and **public order**. Without it, any protest blocking a street could lead to arrests for obstruction. With it, peaceful protesters who play by the rules get legal protection. However, the law also gives authorities significant power to block events they deem against the \"public interest\"—a broad term that leaves room for political judgment."},"issue_detection":{"absurdities":[],"contradictions":[]}},"importantCases":[],"_links":{"self":"/api/acts/public-assemblies-act-1972","history":"/api/acts/public-assemblies-act-1972/history","analysis":"/api/acts/public-assemblies-act-1972/analysis","conflicts":"/api/acts/public-assemblies-act-1972/conflicts","importantCases":"/api/acts/public-assemblies-act-1972/important-cases","documents":"/api/acts/public-assemblies-act-1972/documents"}}
