Understanding Investor–State Dispute Settlement in the Mining Sector

The document introduces investor-state dispute settlement (ISDS) as a mechanism allowing foreign investors to bring claims against host states before international tribunals. It highlights that the mining sector is one of the most frequent targets of such claims, which can result in large monetary awards and delay regulatory reforms. The brief details how consent for ISDS is established through investment treaties, domestic laws, and contracts, and notes a growing trend of claims linked to the demand for critical minerals. It concludes with recommendations for governments to manage ISDS risks through inter-agency coordination, thorough documentation, and legal coherence.

• The mining sector is a primary user of ISDS, with 15 of the 58 cases recorded by UNCTAD in 2024 originating from this sector. ICSID statistics for the 2025 fiscal year show that 43% of registered cases related to oil, gas, and mining, with 15 cases specifically from the mining sector.
• ISDS claims in mining often challenge government decisions regarding the termination of concessions, licensing regime changes, and environmental or social restrictions. Examples include cases involving the termination of a zinc mine concession in Montenegro and the denial of coal project permits in Australia.
• Consent for ISDS is typically established through three main channels: international investment treaties (of which over 2,230 remain in force), domestic investment or mining laws, and specific investor-state contracts. Some domestic laws, such as the 1995 Guinea Investment Code, provide broad advance consent to arbitration.
• Mining contracts often include stabilization clauses that shift regulatory risk to the host state. When combined with broad arbitration clauses, these can turn updates to regulations on royalties, water, or tailings into compensable claims.
• African, Latin American, and Caribbean states are the most frequent respondents in mining-related ISDS claims. In 2024, nine of the 19 mining sector claims instituted involved states from these regions, including Burkina Faso, Colombia, Mozambique, Panama, and Tunisia.
• Arbitral awards are binding and generally enforceable under the New York Convention or the ICSID Convention, with no appeal on the merits. Remedies are primarily monetary damages, which can be very large, such as a case where Pakistan was ordered to pay over USD 5.9 billion.
