KINGSTON — Deliberations within the Council and Assembly of the International Seabed Authority (ISA) have reached an acute statutory impasse concerning the transition from mineral prospecting to commercial exploitation in the Area. While exploration contracts for polymetallic nodules, polymetallic sulphides, and cobalt-rich ferromanganese crusts have operated for over two decades, the regulatory framework governing commercial extraction—the draft Exploitation Regulations (the “Mining Code”)—remains incomplete.
The protracted negotiations have pushed the procedural machinery of the 1994 Agreement relating to the Implementation of Part XI of the United Nations Convention on the Law of the Sea to its limits. Following the invocation of the “Two-Year Rule” by a sponsoring state, member states face an unresolved institutional question: Does the ISA Council bear a mandatory duty to provisionally approve commercial plans of work in the absence of an adopted regulatory code, or does UNCLOS Article 145 require an absolute environmental bar until sufficient scientific baselines are established?
1. The Statutory Trigger: Section 1, Paragraph 15 of the 1994 Agreement
The procedural mechanism known as the “Two-Year Rule” is codified not in the body of UNCLOS itself, but in the Annex to the 1994 Implementation Agreement, Section 1, paragraph 15. The provision was originally negotiated as an institutional compromise to reassure industrialized mining states that the newly established Authority would not indefinitely delay commercial exploitation through regulatory inaction.
Under paragraph 15:
- If a state party whose national intends to apply for approval of a plan of work for exploitation notifies the Council that it wishes to begin commercial activities, the Council “shall complete the elaboration of the rules, regulations and procedures necessary to facilitate the approval of plans of work for exploitation” within two years of the submission date.
- Subparagraph (c) Directive: If the Council has not completed the regulations within that two-year period, and an application for approval of a plan of work is submitted, the Council “shall in any case consider and provisionally approve such plan of work based on the provisions of the Convention and any rules, regulations and procedures that the Council may have adopted provisionally, or on the basis of the norms contained in the Convention and the terms and principles contained in this Annex as well as the principle of non-discrimination.”
While the text directs the Council to “consider and provisionally approve” a plan of work, it does not specify whether approval is automatic or contingent upon substantive review.
2. Textual Reconciliation: Section 1(15) vs. Article 145 UNCLOS
Mining consortia and their sponsoring states argue that subparagraph (c) creates a non-discretionary statutory obligation: once the temporal threshold has lapsed and a formal application is tendered, the Council lacks legal authority to impose a moratorium or decline consideration.
However, under Article 2 of the 1994 Implementation Agreement, the provisions of the Agreement and Part XI of UNCLOS must be interpreted and applied together as a single instrument. Consequently, Section 1(15) cannot be read in clinical isolation from the fundamental environmental disciplines governing the Area:
| Statutory Parameter | Section 1(15) of 1994 Agreement | UNCLOS Article 145 Environmental Mandate |
|---|---|---|
| Procedural Objective | Prevents administrative delay; directs provisional consideration of plans of work. | Mandates adoption of rules to ensure effective protection of the marine environment from harmful effects. |
| Standard of Review | Guided by the norms of the Convention and the principle of non-discrimination. | Requires prevention of damage to flora and fauna, interference with ecological balance, and protection of seabed resources. |
| Institutional Discretion | Directs the Council to “provisionally approve” on the basis of existing norms. | Forbids activities where scientific evidence is inadequate to demonstrate that serious environmental harm will not occur. |
In its 2011 Advisory Opinion (Responsibilities and obligations of States with respect to activities in the Area), the Seabed Disputes Chamber of the International Tribunal for the Law of the Sea (ITLOS) clarified that sponsoring states and the Authority are bound by the precautionary approach (Principle 15 of the Rio Declaration) and a continuous duty of due diligence.
The Chamber affirmed that the precautionary approach is integral to the obligation to ensure effective protection under Article 145. Where scientific data regarding deep-sea benthic ecosystems, sediment plume dispersion, and midwater food-web disruptions remain deficient, approving a plan of work would contradict the Authority’s due diligence obligations.
3. The Common Heritage of Humankind and Benefit-Sharing Mechanisms
Under UNCLOS Article 136, the Area and its resources are designated as the Common Heritage of Humankind. Article 140(2) establishes that the Authority must provide for the equitable sharing of financial and other economic benefits derived from activities in the Area through appropriate mechanisms.
Approving a unilateral commercial application under subparagraph (c) prior to final consensus on the Mining Code creates structural legal voids:
- Absence of an Agreed Financial Mechanism: The financial terms of contracts—including the precise royalty rate per dry metric ton of recovered ore, windfall profit splits, and environmental liability trust contributions—remain unfinalized. Approving a provisional plan without an established financial regime risks alienating resources without the equitable compensation legally required by Article 140.
- The Institutional Role of the Legal and Technical Commission (LTC): Under Article 165(2)(b), the LTC must review applications and submit formal recommendations to the Council. If the LTC cannot evaluate an environmental impact statement because uniform environmental thresholds and baseline standards have not been adopted, it cannot lawfully formulate an affirmative recommendation.
- The Moratorium Coalition: A growing bloc of state parties within the ISA Assembly has formally advocated for a “precautionary pause” or moratorium, maintaining that no commercial exploitation may commence until the complete regulatory regime, including binding environmental standards and guidelines, is formally adopted by consensus.
Systemic Trajectory
The dispute over the Two-Year Rule exposes a structural tension between private capital stabilization and multilateral ocean governance.
If the Council provisionally approves commercial exploitation without a finalized Mining Code, it risks contentious litigation before the Seabed Disputes Chamber under Article 187 of UNCLOS for breach of its environmental trustee obligations. Conversely, indefinite administrative deferral without clear legal criteria risks unilateral national licensing, threatening the integrity of the centralized international regime established under Part XI.
