They create a legal framework for securing \"designated areas\" (restricted zones within the mine site) to prevent theft of diamonds and protect the mining operation.\n\n**Who it affects:**\n\n*   **The \"Owners\"** — the mining company (originally Ashton Joint Venture, later Argyle Diamond Mines) who must build and maintain fences, walls, signs, and search facilities.\n*   **Security officers** — who conduct searches, control access points, and detain suspected offenders.\n*   **Workers and visitors** — anyone entering or leaving the designated areas who may be searched, required to surrender property, or detained if suspected of theft.\n*   **The general public** — who face penalties for trespassing or damaging security infrastructure.\n\n**Key requirements:**\n\n*   **Physical barriers:** The Owners must erect security fences (heavy chain-link, 1.8m high with barbed wire) or security walls around designated areas, unless natural features (cliffs, lakes, waste dumps over 30m high) provide equivalent security.\n*   **Controlled access:** All entry and exit must go through designated checkpoints manned by security officers, with specific warning signs posted.\n*   **Searches:** Security officers can search people and property entering or leaving. Personal searches must respect privacy (same-sex officers, third person present, no x-rays). Property searches can use approved x-ray machines.\n*   **Record keeping:** Agreements and searches must be recorded and kept for 3 years.\n*   **Offences:** Damaging fences or signs, obstructing security officers, or breaching the regulations carries fines up to $500. Unlawful entry or exit can attract penalties up to $5,000 or one year imprisonment (under the parent Act).\n\n**Why it matters:**\n\nDiamond mining involves extremely valuable, easily concealable goods. These regulations create a \"secure zone\" similar to airport security but for a mining site — balancing the need to prevent theft with basic protections for personal dignity during searches. They reflect the unique security challenges of the diamond industry, where small stones worth millions can fit in a pocket."}},"importantCases":[],"_links":{"self":"/api/acts/diamond-ashton-joint-venture-security-regulations-1982","history":"/api/acts/diamond-ashton-joint-venture-security-regulations-1982/history","analysis":"/api/acts/diamond-ashton-joint-venture-security-regulations-1982/analysis","conflicts":"/api/acts/diamond-ashton-joint-venture-security-regulations-1982/conflicts","importantCases":"/api/acts/diamond-ashton-joint-venture-security-regulations-1982/important-cases","documents":"/api/acts/diamond-ashton-joint-venture-security-regulations-1982/documents"}}
