Investment Treaty Arbitrations (ITAs) are a form of dispute resolution between foreign investors and sovereign states. They arise from violations of international investment agreements or bilateral investment treaties (BITs), where an investor claims that a state has breached its obligations under such treaties. These obligations typically include fair treatment, protection from expropriation, and the right to a neutral forum for dispute resolution. Investment treaty arbitration is an essential aspect of international investment law, offering foreign investors a means to resolve disputes with host governments outside of national courts.
Investment treaties are international agreements that set out the terms and conditions for foreign investment between two or more countries. The primary purpose of these treaties is to protect the rights of foreign investors by ensuring that their investments are treated fairly, equitably, and in accordance with established international standards.
Investment treaty arbitrations are primarily part of the Investor-State Dispute Settlement (ISDS) mechanism, which allows foreign investors to initiate arbitration against sovereign states when they believe their rights under investment treaties have been violated. The ISDS mechanism provides investors with an alternative to local courts, which may not offer impartial or fair resolutions, particularly if the state is a party to the dispute.
Disputes in investment treaty arbitration often arise from the following issues:
If an investor believes their rights under a BIT have been violated, they can initiate arbitration against the host state. This is typically done by submitting a notice of dispute and requesting arbitration under the rules of a specific arbitration institution, such as the International Centre for Settlement of Investment Disputes (ICSID), UNCITRAL, or the Permanent Court of Arbitration (PCA).
The arbitration is conducted by an independent panel of arbitrators selected by both the investor and the state. The tribunal has the authority to hear the case, interpret the treaty, and make a binding decision.
After considering the evidence and arguments, the tribunal issues a ruling (an award) which can involve monetary compensation, orders for restitution, or other forms of relief. The award is typically final and binding, with limited opportunities for appeal.
In this high-profile case, the tobacco company Philip Morris initiated arbitration against Australia, claiming that plain packaging laws for tobacco products violated the Australia-Hong Kong Bilateral Investment Treaty. The case raised issues of public health policy vs. investor protection.
Chevron filed an arbitration claim against Ecuador under the U.S.-Ecuador Bilateral Investment Treaty after Ecuador’s courts held the company liable for environmental damage caused by oil drilling in the Amazon rainforest. The case highlights the intersection of environmental law and investment protection.
Before investing in a foreign country, investors should conduct thorough due diligence on the host country’s legal environment, including the risk of expropriation or unfair treatment.
Investors should carefully review and negotiate the dispute resolution clauses in investment treaties, ensuring that the right to initiate arbitration is protected and clearly defined.
Once an award is granted, investors can pursue enforcement of the arbitral award through national courts, subject to the provisions of international treaties like the New York Convention.
Suppose an international mining company invests in a developing country to extract natural resources. The government of the host country later passes a new law that dramatically increases taxes on foreign-owned mining companies, significantly affecting the company's profitability.
