Applicable Law and Dispute Resolution Design for International Investment Contracts

Applicable Law and Dispute Resolution Design for International Investment Contracts

International investment contracts encompass a wide range of areas, including concession/implementation agreements with public authorities, energy and infrastructure projects, mining and licensing relationships, joint ventures, and long-term supply and operation agreements. Two factors determine the fate of these contracts: applicable law and a well-designed dispute resolution strategy. Because the "long-term" nature of investment, coupled with factors such as changing regulations, currency risk, permitting processes, and public interest interventions, means uncertainty is the most costly outcome.

1) Applicable law: not a single line, but an entire architecture

The phrase "This contract is governed by Law X" is necessary in the contract, but often insufficient. In international investments, the applicable law should generally be considered on a three-tiered basis:

1. Contractual law (governing law): The law of the country chosen by the parties determines the formation, interpretation, performance, default, compensation, and liability regime of the contract.
2. Host country's mandatory regulations: Mandatory regulations in areas such as permits, licenses, environment, taxation, competition, and public procurement/supervision effectively come into play despite the "choice of law." Therefore, the investor should map out the areas of conflict between the chosen law and the host country's legislation in advance.
3. Impact of international law: In state-backed projects or when there is intense contact with public authority, investment protection agreements (instruments similar to BITs/DTAs), fair and equitable treatment, expropriation standards, and the prohibition of discrimination can create a "non-contractual" layer of protection.

The critical point in this architecture is not simply choosing "familiar law" when selecting applicable law, but ensuring predictability against the real risks of the investment (permit revocation, tariff changes, sanctions/embargoes, transfer restrictions, unilateral intervention by public authorities) .

2) Stabilization, adaptation, and renegotiation

One of the most debated areas in long-term investment contracts is "regulatory change." Therefore:

• Stabilization agents (to limit the impact of changes on the investor),
• Provisions for adjustment/balancing (hardship, economic balance, tariff revision),
• Renegotiation triggers (such as changes to licensing requirements, increased tax burden, restrictions on currency transfers)
  are where the debate over applicable law is linked to "commercial reality."

3) Dispute resolution design: “where, how, when?”

Dispute resolution design is not simply about choosing “arbitration/court”; it's about process engineering. A robust design clarifies the following decisions:

• Forum selection: Arbitration is often preferred in state/institution-led projects; in private law relationships, hybrid court and arbitration methods may be observed.
• Rules and structure: Institutional arbitration (e.g., ICC-like) or ad hoc (UNCITRAL-like)? Institutional structure can strengthen discipline regarding timelines, appointments, costs, and procedures.
• The seat of arbitration determines the cancellation regime and the court support. The "neutral country" approach is frequently used in risk management.
• Language, privacy, document submission: a broad document submission approach similar to e-discovery, or a more limited continental European approach? This choice directly impacts cost.
• Multi-tier requirements: Stages such as negotiation, management discussion, mediation, and arbitration, if not clearly defined, can turn into a "condition for litigation" debate. It is essential to clearly state the timelines, who will participate, and the criteria for failure.
• Temporary legal protection: The accessibility and standards of mechanisms such as emergency arbitration, interim measures, security, and evidence gathering should be determined.
• Risk of parallel proceedings: Provisions such as "fork-in-the-road," waiver, and consolidation/joinder should be considered to address the potential overlap between contractual arbitration and investment arbitration/international protection claims.

4) Practical result: Design “prevents conflict”, or at least makes it cheaper

A well-designed legal framework and dispute resolution strategy increases trust between parties, reduces "jurisdiction/applicable law" disputes from the outset, and allows the focus to be on the merits of the dispute. In international investment contracts, the goal is not just to win, but to minimize uncertainty and ensure the sustainability of the investment.
