Investment Treaty Arbitration: A Complete Guide for Bangladeshi Parties

May 15, 2026 12 min read by Tahmidur Remura Wahid

Introduction

Investment treaty arbitration is a specialized form of dispute resolution that arises from international investment agreements between states and foreign investors. It serves as a neutral and binding mechanism to resolve disputes relating to breaches of investment treaties, protecting investors against unfair treatment and expropriation by host states. This legal tool is particularly important for Bangladeshi businesses and investors seeking to expand their commercial activities beyond national borders in an increasingly globalized economy. With Bangladesh emerging as a significant player in sectors such as ready-made garments (RMG), energy, and infrastructure, the ability to rely on robust dispute resolution frameworks like investment treaty arbitration provides essential legal certainty and risk mitigation.

For Bangladeshi investors, investment treaty arbitration offers safeguards under bilateral investment treaties (BITs) and multilateral agreements that Bangladesh has entered into with other jurisdictions. These treaties often provide protections such as fair and equitable treatment, full protection and security, and protection against unlawful expropriation. By invoking investment treaty arbitration, investors can seek redress from independent arbitral tribunals seated in jurisdictions such as Washington D.C. or The Hague, ensuring impartial adjudication outside the domestic courts of disputing states. Thus, understanding the intricacies of investment treaty arbitration is vital for Bangladeshi companies and legal practitioners involved in cross-border transactions.

Overview Of ICSID / PCA / UNCITRAL Investment Treaty Tribunals

Investment treaty arbitration is administered by several prominent international institutions, each with distinct histories, governance structures, and procedural rules. The International Centre for Settlement of Investment Disputes (ICSID), the Permanent Court of Arbitration (PCA), and ad hoc tribunals under the United Nations Commission on International Trade Law (UNCITRAL) rules constitute the primary forums for resolving investment treaty disputes.

International Centre For Settlement Of Investment Disputes (ICSID)

Established in 1966 under the auspices of the World Bank, ICSID is the most prominent institution for investment treaty arbitration. ICSID’s governance is structured through its Administrative Council, composed of representatives from contracting states, and the Secretariat, which handles day-to-day administration. ICSID’s jurisdiction is consensual, activated through investment treaties or contracts expressly providing for ICSID arbitration. Since its inception, ICSID has administered over 700 cases, reflecting its central role in investment arbitration globally.

Permanent Court Of Arbitration (PCA)

The PCA, founded in 1899, is one of the oldest international arbitration institutions, operating from The Hague, Netherlands. It administers a broad spectrum of disputes, including investment treaty arbitration, under various procedural rules. The PCA offers flexibility through institutional arbitration and facilitation of ad hoc proceedings. Its governance involves a Council composed of representatives from member states who oversee administrative functions. The PCA has gained prominence for handling complex multi-party and multi-jurisdictional investment disputes.

UNCITRAL Arbitration Rules

UNCITRAL provides a set of procedural rules widely used for ad hoc investment treaty arbitrations. Unlike ICSID and PCA, UNCITRAL does not constitute an institution but offers flexible procedural norms adaptable to parties’ agreements. Arbitrators in UNCITRAL cases are appointed by the disputing parties, and the tribunal operates without institutional oversight, making it a preferred mechanism for parties seeking procedural autonomy. The UNCITRAL framework supports confidentiality, interim measures, and efficient dispute resolution tailored to the parties’ needs.

Investment Treaty Arbitration: Rules And Procedure

The procedural framework for investment treaty arbitration varies depending on the institution or rules chosen by the parties. However, common elements govern the initiation, conduct, and conclusion of these arbitrations, ensuring fairness, efficiency, and impartiality.

Commencement Of Arbitration

Investment treaty arbitration typically begins with the submission of a Notice of Arbitration by the investor to the respondent state and the administering institution (if institutional arbitration). The Notice must specify the nature of the dispute, the relevant treaty provisions, and relief sought. Under ICSID, the Notice is submitted to the ICSID Secretariat, triggering constitution of the arbitral tribunal. Under UNCITRAL rules, the Notice is sent to the respondent, and the parties agree on the arbitrators or seek appointments through appointing authorities.

Appointment Of Arbitrators

Tribunals usually consist of three arbitrators: one appointed by each party and a presiding arbitrator jointly selected. In ICSID cases, the ICSID Secretariat confirms appointments to ensure neutrality and qualifications. The PCA provides appointing authorities for arbitrator nominations or default appointments if parties fail to agree. UNCITRAL rules provide similar mechanisms for arbitrator appointment through designated appointing authorities or the Secretary-General of ICSID or PCA when applicable. Arbitrator independence and impartiality are paramount, and challenges can be raised under procedural rules for conflicts of interest.

Procedural Timelines And Phases

Investment treaty arbitration involves several stages, including preliminary meetings, written submissions, hearings, and post-hearing briefs. The procedural timetable is often agreed upon early to promote efficiency. Typical timelines range from 12 to 24 months from commencement to award, although complexity may extend this period. ICSID rules mandate a preliminary conference within 45 days of tribunal constitution to set procedural directions. The PCA and UNCITRAL allow flexible scheduling but encourage prompt resolution.

Interim Measures And Provisional Relief

Arbitral tribunals possess the authority to grant interim measures to preserve assets, evidence, or jurisdictional integrity pending the final award. ICSID tribunals can issue provisional measures under Article 47 of the ICSID Convention, while PCA and UNCITRAL tribunals rely on procedural rules enabling such relief. These measures are critical to protect the parties’ rights and prevent irreparable harm during arbitration. Parties may also seek urgent relief from courts before tribunal constitution.

Confidentiality And Transparency

Confidentiality is a hallmark of investment treaty arbitration, providing parties privacy and protection of sensitive commercial information. ICSID proceedings are generally confidential, although parties may consent to publication of awards. PCA and UNCITRAL arbitrations are also confidential unless parties agree otherwise or institutional rules mandate limited disclosure. The balance between confidentiality and public interest transparency continues to evolve, with some tribunals adopting transparency rules for greater openness.

Costs And Fees

The costs of investment treaty arbitration include institutional fees, arbitrators’ remuneration, legal fees, and administrative expenses. ICSID charges fees based on the amount in dispute and duration, with cost rules outlined in its Schedule of Fees. PCA fees vary depending on case complexity, arbitrator fees, and administrative services. UNCITRAL arbitrations incur costs primarily from arbitrators’ fees and legal representation, as there is no institutional fee. Parties typically bear their own legal costs but may seek cost awards at the tribunal’s discretion.

Why Bangladeshi Parties Choose Investment Treaty Arbitration

Bangladeshi investors and businesses increasingly favor investment treaty arbitration due to its neutrality, enforceability, and procedural safeguards. The global nature of Bangladesh’s cross-border trade and investments demands dispute resolution mechanisms that transcend local judicial systems, which may be perceived as less predictable or susceptible to political influences. Investment treaty arbitration offers Bangladeshi parties a forum backed by international legal frameworks and institutions, ensuring impartial adjudication.

The ready-made garments (RMG) sector, a cornerstone of Bangladesh’s economy, often engages in international supply contracts and joint ventures requiring protection against host state actions. Similarly, the energy and infrastructure sectors involve significant foreign direct investment and long-term contracts that may expose investors to regulatory changes or expropriatory measures. Investment treaty arbitration provides a critical legal recourse in such circumstances, enabling Bangladeshi investors to uphold their rights and secure fair compensation when disputes arise.

Moreover, Bangladesh’s increasing participation in bilateral investment treaties and multilateral agreements underscores the relevance of investment treaty arbitration. By incorporating well-drafted arbitration clauses in contracts and treaties, Bangladeshi parties ensure access to internationally recognized dispute resolution mechanisms. This approach mitigates risks associated with commercial litigation in Bangladesh and complements alternative dispute resolution (ADR) strategies, fostering a conducive environment for foreign investment and trade.

Enforcement Of Investment Treaty Arbitration Awards In Bangladesh

The enforceability of investment treaty arbitration awards in Bangladesh is governed primarily by the Arbitration Act 2001 (Bangladesh) and the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards 1958, to which Bangladesh is a signatory. This legal framework facilitates the recognition and enforcement of foreign arbitral awards, including those arising from investment treaty arbitration conducted under ICSID, PCA, or UNCITRAL rules.

New York Convention 1958 And Bangladesh

Bangladesh acceded to the New York Convention in 1998, incorporating its provisions into domestic law through the Arbitration Act 2001. Under Article III of the Convention, Bangladeshi courts are mandated to recognize and enforce arbitral awards made in other contracting states, subject to limited grounds for refusal. This international instrument plays a pivotal role in assuring foreign investors that arbitral awards can be enforced effectively within Bangladesh’s jurisdiction.

Arbitration Act 2001 (Bangladesh) And Section 45

The Arbitration Act 2001 provides the statutory basis for arbitration proceedings and enforcement of awards in Bangladesh. Section 45 specifically addresses the enforcement of foreign arbitral awards, stipulating that such awards shall be enforced as if they were decrees of the court. The Act outlines procedural requirements for filing applications for enforcement and prescribes grounds upon which enforcement may be refused, closely aligned with the New York Convention’s Article V.

Grounds For Refusal Of Enforcement

Bangladeshi courts may refuse enforcement of investment treaty arbitration awards on limited grounds, including incapacity of parties, invalid arbitration agreement, improper notice of arbitration, awards exceeding tribunal jurisdiction, violation of public policy, or awards not yet binding. However, these grounds are construed narrowly to promote enforcement and uphold Bangladesh’s obligations under the New York Convention. The judiciary has generally adopted a pro-enforcement stance, recognizing the importance of upholding international arbitration commitments to attract foreign investment.
