Foreign investors who commit capital abroad take on a risk that purely domestic investors never face: the risk that the host government itself will act against them. A change in tax policy, a revoked license, a nationalized asset or a discriminatory regulation can erase years of expected return through a single administrative order. Domestic courts are rarely a realistic remedy, since the same state that caused the harm often controls the forum that would have to judge it. This is precisely the gap that international investment treaties were designed to close, and it is why investor-state arbitration has become the primary route through which investors seek redress against sovereign conduct.
Bilateral investment treaties, or BITs, are agreements between two states that extend defined legal protections to investors from one country operating in the other. A global network of more than two thousand such treaties, together with multilateral frameworks like the Energy Charter Treaty and the investment chapters found in modern free trade agreements, gives investors substantive rights that exist independently of domestic law: fair and equitable treatment, protection against direct and indirect expropriation without compensation, full protection and security, and national and most-favoured-nation treatment. When a state breaches these standards, an investor may bring a claim directly against it before an international tribunal, most often under the ICSID Convention or UNCITRAL Rules, without needing its own government’s consent. An experienced investment treaty dispute arbitrator hears exactly these claims, applying treaty text, customary international law and the substantial body of jurisprudence built up through decades of ICSID and UNCITRAL awards.
Energy investments are especially exposed to this kind of state action. License revocations, retroactive changes to subsidy regimes, and outright expropriation of oil, gas, and power assets have produced some of the largest investor-state awards on record, and sunset clauses in older treaties mean claims can still arise years after the underlying measure was taken. An energy dispute arbitrator must be equally comfortable with production-sharing contracts, tariff regulation and the treaty standards that sit above them, since energy disputes frequently proceed as parallel commercial and investment treaty claims arising from the very same government measure.
Mining and metals present a parallel pattern, often described as resource nationalism: mining code overhauls, windfall royalty increases, forced state participation and outright concession revocations targeting gold, copper, cobalt and lithium projects. These measures routinely trigger claims under the fair and equitable treatment and expropriation standards, and the arbitral record in this sector continues to grow across Africa, Latin America and parts of Asia. A mining dispute arbitrator with genuine investment treaty grounding, rather than commercial arbitration experience alone, is best placed to weigh the legitimate exercise of regulatory sovereignty against a state’s binding treaty commitments.
Infrastructure concessions carry a similar exposure. Roads, ports, airports and power transmission projects are typically structured through long-term agreements with a state or a state-owned entity and disputes arise when a government alters tariffs, cancels a concession, or interferes with the project financing arrangements agreed at the outset. Because these disputes often combine a contractual breach with a treaty violation, they demand an infrastructure dispute arbitrator who can navigate concession agreements, host government agreements and the investment treaty layer sitting above them, all at once, without losing sight of which claim belongs to which forum.
The process itself is deliberately structured to protect both sides from delay and from an uneven playing field. Once an arbitrator accepts appointment following a conflict check, the tribunal addresses jurisdictional objections and sets a procedural timetable before moving to document production, witness evidence and expert reports on quantum. Only after this rigorous evidentiary phase does the tribunal deliberate and issue a reasoned award, one that can then be enforced under the ICSID Convention or the New York Convention across well over a hundred signatory states. It is this combination of a fixed procedure, a treaty-based standard of review and cross-border enforceability that gives investors confidence that a favorable outcome will actually translate into recovery.
Investors protect themselves well before a dispute ever arises. Structuring an investment through a jurisdiction with a strong treaty network, insisting on umbrella clauses that elevate contractual promises to treaty-level protection, and preserving a genuine choice between ICSID, UNCITRAL, PCA and institutional rules all matter at the drafting stage. But once a state measure has already caused harm, the single most important safeguard is the independence of the tribunal that will decide the claim. Investor-state arbitration exists precisely because it removes that decision from the courts of the state accused of wrongdoing and places it before a neutral panel bound only by the treaty and international law.
Whatever the sector, parties, counsel and institutions seeking a neutral decision-maker for investor-state and sovereign disputes may appoint The International Arbitrator as sole arbitrator or as a member of an arbitral tribunal in ICSID, UNCITRAL, PCA, ICC or SCC proceedings, drawing on institutional experience gained directly within the ICSID system and years of cross-border practice across the jurisdictions where investment treaty claims most frequently arise.
Propose Harshavardhan Sancheti as accepting appointment as sole arbitrator via party nomination, institutional appointment (ICC, LCIA, SIAC) or ad hoc proceedings.
