This includes electricity, water, fuel, food supply, transport, telecommunications, and healthcare.\n\n**Key protections and limits:**\n- **No self-incrimination**: People can't be forced to give information that would incriminate themselves\n- **Compensation**: Owners of requisitioned property must be paid for damage and loss of use\n- **Immunity**: People following Ministerial directions are protected from civil and criminal liability\n- **Parliamentary oversight**: Extensions beyond 14 days require both Houses of Parliament to approve\n- **Attorney-General approval needed** to prosecute offences under the Act\n\n**Who it affects:**\n- **Businesses and individuals** providing essential services (they must comply with directions)\n- **Property owners** (their assets can be temporarily requisitioned)\n- **Everyone** during emergencies (price controls apply, and it's illegal to interfere with essential service workers)\n\n**Why it matters:**\nThis is a \"break glass in case of emergency\" law that dramatically expands government power during crises.

Persons and businesses face criminal and civil penalties for non‑compliance; owners whose property is used are entitled to compensation. The purpose stated is to protect the community from interruption of essential services; the measure shifts decision authority to the Governor and Minister and imposes compliance costs and discretional burdens on private providers and the public."},"summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"Unable to assess whether the Act's scope has changed from its original intent — the legislative text was not successfully retrieved.
