International Investment Arbitration

International Investment Arbitration

Malins Chambers is highly experienced in representing states, investors, and corporations in international investment arbitration. Our barristers are regularly instructed in complex, high-value disputes arising under bilateral investment treaties (BITs), multilateral treaties, and investment contracts, often involving allegations of expropriation, unfair treatment, or breach of investor protections.

Our Expertise in International Investment Arbitration

We advise and act in disputes concerning:

  • Bilateral & Multilateral Investment Treaties – including claims under ICSID, UNCITRAL, LCIA, ICC, and SCC rules.

  • Expropriation & Nationalisation Claims – unlawful state interference with property and investments.

  • Fair & Equitable Treatment (FET) and Full Protection & Security obligations.

  • Stabilisation & Contractual Protection Clauses – disputes under long-term infrastructure, mining, and energy contracts.

  • Jurisdictional & Admissibility Challenges – determining tribunal competence and investor standing.

  • Damages & Valuation of Investments – assessing compensation for expropriated or impaired assets.

  • Recognition & Enforcement of Arbitral Awards – pursuing or resisting enforcement under the New York Convention.

  • Public International Law Issues – including state immunity, treaty interpretation, and human rights overlaps.

Domestic & International Reach

Our barristers appear before ICSID tribunals, UNCITRAL panels, ICC, LCIA, SCC, and ad hoc tribunals, as well as in proceedings before the English courts related to enforcement and challenges to arbitral awards. Members of Chambers also have experience in cases involving emerging markets, developing economies, and offshore jurisdictions.
