International Seabed Authority

27 Min Read

Introduction

The International Seabed Authority (ISA) is an international organisation established under Part XI of the United Nations Convention on the Law of the Sea (UNCLOS) to organise and control activities in the Area.

The Area means the seabed, ocean floor and subsoil beyond the limits of national jurisdiction.

The ISA is therefore central to the international legal regime governing:

  • exploration of deep seabed minerals;
  • exploitation of those resources;
  • environmental protection;
  • benefit sharing;
  • participation of developing States.

Its legal framework is primarily found in UNCLOS Articles 156–185, together with Annex III, Annex IV, and the 1994 Agreement relating to the Implementation of Part XI of UNCLOS.

Core Formula

The Area

Common Heritage of Mankind

International Seabed Authority

Organises + Controls Activities

Prospecting → Exploration → Exploitation

Benefit of Mankind + Environmental Protection

Meaning of International Seabed Authority

The ISA is the international organisation through which States Parties organise and control activities in the Area.

It does not exercise sovereignty over the Area like a State exercises sovereignty over its territory.

Instead, it performs regulatory, administrative and supervisory functions under UNCLOS.

Important Distinction

ISA → International Administration and Regulation

State → Sovereignty over its national territory

Therefore:

ISA ≠ Sovereign Owner of the Seabed

The principal provisions are:

  • Article 156 → Establishment of the Authority
  • Article 157 → Nature and fundamental principle
  • Article 158 → Organs of the Authority
  • Article 159 → Assembly
  • Article 160 → Powers and functions of the Assembly
  • Article 161 → Council
  • Article 162 → Powers and functions of the Council
  • Article 163 → Council organs
  • Article 164 → Economic Planning Commission
  • Article 165 → Legal and Technical Commission
  • Article 166 → Secretariat
  • Article 167 → Secretariat
  • Article 168 → Secretary-General
  • Article 169 → Staff
  • Article 170 → Enterprise
  • Articles 171–175 → Financial provisions
  • Articles 176–185 → Legal status, privileges, immunities and related matters

Article 156 – Establishment

Article 156 UNCLOS

An international organisation called the:

International Seabed Authority

is established to organise and control activities in the Area, particularly with a view to administering the resources of the Area.

All States Parties to UNCLOS are ipso facto members of the Authority.

Article 157 – Nature of the Authority

The ISA is the organisation through which States Parties organise and control activities in the Area.

Its authority is therefore based on:

UNCLOS

and applies specifically to:

Activities in the Area

It is not a general authority over all oceans.

Headquarters

The headquarters of the ISA are located in:

Kingston, Jamaica

Membership

States that are parties to UNCLOS become members of the ISA under Article 156.

The ISA therefore has a broad international membership corresponding to participation in the UNCLOS system.

Relationship with the Area

The relationship can be understood as:

Area

→ Seabed beyond national jurisdiction

Common Heritage of Mankind

ISA

→ Organises and controls activities

The ISA therefore gives institutional form to the Common Heritage of Mankind principle.

Common Heritage of Mankind

The ISA cannot be understood separately from Article 136 UNCLOS.

Article 136 provides that:

The Area and its resources are the common heritage of mankind.

This means that the ISA’s regulatory role is intended to ensure that the resources of the Area are not appropriated unilaterally.

Article 137 – No Appropriation

No State may claim or exercise sovereignty or sovereign rights over any part of the Area or its resources.

Similarly, no State or natural or juridical person may appropriate any part of the Area.

Therefore:

ISA Regulation → Prevents Unilateral Appropriation

Main Functions of the ISA

The ISA performs several major functions.

Organising Activities

It organises activities concerning mineral resources in the Area.

Controlling Activities

It controls activities through:

  • regulations;
  • contracts;
  • plans of work;
  • compliance mechanisms.

Approving Exploration

It considers and approves plans of work for exploration.

Regulating Exploitation

It is responsible for developing and implementing the regulatory framework for exploitation.

Environmental Protection

It establishes rules and procedures for protecting the marine environment.

Benefit Sharing

It develops mechanisms concerning the equitable sharing of financial and other economic benefits derived from activities in the Area.

The ISA Is Not a Mining Company

The ISA primarily performs an:

International Regulatory Function

It should not be confused with a commercial mining company.

The system does, however, include the Enterprise, which was envisaged under UNCLOS as an operational arm for activities in the Area.

Principal Organs

Article 158

The principal organs of the ISA are:

  • Assembly
  • Council
  • Secretariat

The Enterprise is also established as an organ under Article 170.

The ISA also has specialised bodies, including the:

  • Legal and Technical Commission;
  • Finance Committee.

The Assembly

Article 159

The Assembly consists of all members of the Authority.

It is the principal policy-making body.

One Member, One Vote

As a general principle, each member has:

One vote

The Assembly therefore provides the broad representative forum within the ISA.

Functions of the Assembly

Article 160

The Assembly has broad powers and functions, including:

  • establishing general policies;
  • considering reports;
  • approving the budget;
  • electing members of certain organs;
  • approving rules and regulations in accordance with UNCLOS;
  • considering matters within the competence of the Authority.

It also exercises important oversight over the Council.

Council

Article 161

The Council is the executive organ of the ISA.

It consists of members elected by the Assembly according to the categories and requirements established by UNCLOS.

The composition is designed to reflect different interests, including:

  • major consumers/importers of minerals;
  • major investors;
  • major exporters of land-based minerals;
  • developing States;
  • geographical representation.

Functions of the Council

Article 162

The Council performs important executive and regulatory functions.

It may:

  • supervise and coordinate implementation of the Area regime;
  • approve plans of work;
  • adopt rules and regulations within its competence;
  • oversee activities in the Area;
  • make recommendations to the Assembly;
  • consider applications and contracts;
  • monitor compliance.

Memory Rule

Assembly → Policy

Council → Execution

Article 165

The Legal and Technical Commission (LTC) is an important subsidiary organ of the Council.

It consists of experts elected on the basis of appropriate qualifications.

Its work covers technical and legal matters relating to:

  • activities in the Area;
  • plans of work;
  • exploration;
  • exploitation;
  • environmental protection;
  • compliance.

The Commission may:

  • review plans of work;
  • make recommendations to the Council;
  • develop technical standards;
  • advise on environmental matters;
  • assess scientific and technical information;
  • monitor compliance-related matters.

Memory Rule

LTC → Legal + Technical Expertise

Finance Committee

The Finance Committee deals with financial matters of the Authority.

It is particularly important for:

  • budgets;
  • financial rules;
  • revenue;
  • expenditure;
  • financial arrangements concerning activities in the Area.

Secretariat

The Secretariat performs the administrative functions of the Authority.

It supports:

  • Assembly;
  • Council;
  • commissions;
  • meetings;
  • documentation;
  • contracts;
  • administrative operations.

Secretary-General

The Secretary-General is the chief administrative officer of the ISA.

The Secretary-General is responsible for:

  • administration;
  • official documentation;
  • implementation of decisions;
  • communication;
  • management of Secretariat functions.

Enterprise

Article 170

The Enterprise is an organ of the ISA.

It was designed to conduct activities in the Area directly, as well as through joint arrangements where appropriate.

Its creation reflects the idea that developing States and the international community should not be excluded from actual participation in deep seabed activities.

The practical operation of the Enterprise has been substantially affected by the 1994 Implementation Agreement.

1994 Implementation Agreement

The original Part XI system was controversial.

Developed States raised concerns about:

  • compulsory technology transfer;
  • production limitations;
  • financial obligations;
  • decision-making;
  • the Enterprise;
  • economic consequences for existing mineral producers.

The 1994 Implementation Agreement modified important aspects of Part XI.

Therefore, the modern ISA framework should be studied as:

UNCLOS Part XI + 1994 Implementation Agreement

Activities in the Area

The ISA’s principal regulatory role concerns:

Prospecting

Exploration

Exploitation

of mineral resources.

Mineral Resources

The resources of the Area include mineral resources found in situ.

Important deep seabed minerals include:

  • polymetallic nodules;
  • polymetallic sulphides;
  • cobalt-rich ferromanganese crusts.

Prospecting

Prospecting involves searching for and identifying mineral resources.

It does not create ownership over the resources.

Exploration

Exploration involves detailed scientific and technical investigation of deposits.

It may include:

  • geological surveys;
  • sampling;
  • environmental baseline studies;
  • resource assessment.

Exploitation

Exploitation involves the actual recovery of mineral resources.

The exploitation regime requires a detailed regulatory framework concerning:

  • commercial recovery;
  • environmental protection;
  • financial terms;
  • compliance;
  • benefit sharing.

Plans of Work

Activities in the Area are carried out pursuant to approved:

Plans of Work

A plan of work provides the framework within which a contractor conducts activities.

The ISA considers matters such as:

  • technical capability;
  • financial capacity;
  • environmental protection;
  • compliance;
  • proposed work programme.

Contracts

The ISA enters into contracts with qualified entities for activities in the Area.

The contractual system allows the Authority to supervise activities rather than allowing unilateral exploitation.

Sponsorship

A contractor may operate under the sponsorship of a State Party.

The sponsoring State has important obligations to ensure compliance with UNCLOS and applicable ISA rules.

State Responsibility

Article 139

States Parties have responsibility to ensure that activities in the Area conducted by:

  • States;
  • State entities;
  • nationals;
  • juridical persons under their jurisdiction or control

are carried out consistently with UNCLOS.

Sponsoring State Due Diligence

The sponsoring State must exercise:

Due diligence

in supervising sponsored activities.

It is not automatically liable for every act of a contractor.

2011 Advisory Opinion

Responsibilities and Obligations of States Sponsoring Persons and Entities with Respect to Activities in the Area

The Seabed Disputes Chamber of ITLOS issued its advisory opinion in 2011.

It is a leading authority on:

  • sponsoring-State responsibility;
  • due diligence;
  • environmental protection;
  • precaution;
  • compliance with ISA rules.

Examination Formula

Sponsorship → Due Diligence → Environmental Protection

Environmental Protection

One of the most important modern functions of the ISA is environmental protection.

Article 145

The Authority must adopt appropriate rules, regulations and procedures to ensure effective protection of the marine environment from harmful effects arising from activities in the Area.

Environmental Concerns

Deep seabed mining may cause:

  • habitat destruction;
  • sediment plumes;
  • biodiversity loss;
  • disturbance of deep-sea ecosystems;
  • disruption of ecological processes.

The ISA’s regulatory system therefore incorporates environmental requirements.

Environmental Impact Assessment

Environmental assessment is important before and during activities.

Relevant matters include:

  • baseline environmental studies;
  • monitoring;
  • impact assessment;
  • mitigation;
  • emergency measures;
  • reporting.

Precautionary Approach

Because scientific understanding of deep-sea ecosystems remains incomplete, environmental regulation increasingly gives importance to:

Precaution

The basic idea is that scientific uncertainty should not automatically justify unrestricted exploitation where serious environmental harm may occur.

Article 140 – Benefit of Mankind

The ISA’s activities must be directed toward the:

Benefit of mankind as a whole

This includes:

  • present generations;
  • future generations;
  • developing States;
  • developed States.

Benefit Sharing

Financial and other economic benefits arising from activities in the Area are to be shared equitably according to the applicable international regime.

This is one of the defining features of the CHM principle.

Developing States

Article 148

Developing States receive special consideration concerning activities in the Area.

The system seeks to facilitate:

  • participation;
  • training;
  • technological development;
  • economic opportunities.

Technology Transfer

Article 144

States and competent international organisations are expected to cooperate in promoting:

Transfer of technology and scientific knowledge

relating to activities in the Area.

The original provisions were modified by the 1994 Implementation Agreement.

Marine Scientific Research

Article 143

Scientific research in the Area is to be conducted:

  • for peaceful purposes;
  • for the benefit of mankind as a whole.

The ISA framework encourages international scientific cooperation.

Rights of Coastal States

Article 142

Activities in the Area must respect the rights and legitimate interests of coastal States where those activities may affect:

  • coastal resources;
  • maritime activities;
  • other legitimate interests.

The ISA therefore does not operate without regard to neighbouring coastal States.

Archaeological and Historical Objects

Article 149

Archaeological and historical objects found in the Area are to be preserved or disposed of for the benefit of mankind as a whole.

Particular regard is given to the rights and interests of States with relevant cultural, historical or archaeological connections.

Peaceful Purposes

Article 141

The Area is open to use exclusively for:

Peaceful purposes

This reinforces the broader peaceful-use principle of the law of the sea.

Privileges and Immunities

The ISA has international legal status and enjoys privileges and immunities necessary for the exercise of its functions.

Relevant UNCLOS provisions and agreements provide protection for:

  • property;
  • officials;
  • archives;
  • communications;
  • premises.

The purpose is to ensure the independent functioning of the organisation.

The ISA possesses the legal capacity necessary for the exercise of its functions.

This allows it to:

  • enter into contracts;
  • acquire and dispose of property;
  • participate in legal proceedings;
  • perform international functions.

Its legal personality is functional, not equivalent to the sovereignty of a State.

ISA and International Seabed Area

The relationship can be represented as:

The Area

Common Heritage

ISA

Regulation

Contractors

Exploration / Exploitation

Benefits + Environmental Protection

ISA and High Seas

The ISA does not regulate all high-seas activities.

Its jurisdiction is specifically connected with:

Activities in the Area

Therefore:

High Seas

→ Part VII

The Area

→ Part XI + ISA

ISA and Continental Shelf

The ISA does not regulate a coastal State’s continental shelf merely because the shelf contains mineral resources.

Continental Shelf

→ Coastal-State sovereign rights

Area

→ ISA international regime

This distinction is crucial.

ISA and Extended Continental Shelf

A coastal State may possess a continental shelf extending beyond 200 nautical miles.

That seabed remains under the coastal State’s jurisdiction.

The ISA becomes relevant only to seabed areas beyond the limits of national jurisdiction.

Therefore:

Beyond 200 nm ≠ Automatically ISA Jurisdiction

ISA and EEZ

The ISA does not administer mineral resources in a State’s EEZ.

The coastal State exercises sovereign rights over resources in its EEZ under Part V.

EEZ

Coastal State

Area

ISA / International Regime

ISA vs ITLOS

These institutions have different functions.

International Seabed Authority

Regulates and administers activities in the Area.

ITLOS

Judicial body dealing with disputes under UNCLOS.

Seabed Disputes Chamber

Has specialised jurisdiction relating to activities in the Area.

ISA vs CLCS

These are also different.

ISA

Deals with:

Activities in the Area

CLCS

Deals with:

Scientific and technical recommendations concerning outer limits of the continental shelf beyond 200 nm

The CLCS does not regulate deep seabed mining.

ISA vs IMO

ISA

→ Deep seabed resources in the Area

IMO

→ International shipping, maritime safety, pollution and related matters

They therefore operate in different fields.

Importance of the ISA

The ISA is important because it transforms the Common Heritage of Mankind principle from a general legal idea into an:

Institutional Regulatory System

Without an institution such as the ISA, the prohibition on unilateral appropriation would be much more difficult to implement.

Challenges Facing the ISA

The ISA faces several major challenges.

Environmental Uncertainty

The ecological consequences of deep seabed mining are not fully understood.

Mining Regulations

Developing detailed exploitation regulations is legally and technically complex.

Benefit Sharing

Determining how financial benefits should be distributed fairly is difficult.

Developing-State Participation

Ensuring meaningful participation requires:

  • technology;
  • finance;
  • capacity building;
  • training.

Commercial Interests

Deep seabed minerals have potential economic value, creating tension between:

  • resource development;
  • environmental protection.

Scientific Knowledge

Regulation must operate despite gaps in knowledge concerning deep-sea ecosystems.

Public International Law

Environmental Protection vs Exploitation

The central policy tension is:

Resource Development

vs

Marine Environmental Protection

The ISA must regulate activities in a way that respects both the resource mandate and the environmental obligations of UNCLOS.

Common Examination Mistakes

Mistake 1: ISA Owns the Area

Incorrect.

The ISA regulates and administers activities; it does not exercise territorial sovereignty.

Mistake 2: ISA Is a UN Organ

Incorrect.

The ISA is an international organisation established under UNCLOS. It is not one of the six principal organs of the United Nations.

Mistake 3: ISA Regulates the Entire Ocean

Incorrect.

Its jurisdiction is principally connected with activities in the Area.

Mistake 4: ISA Controls Coastal-State Continental Shelves

Incorrect.

Coastal States have sovereign rights over their continental shelves.

Mistake 5: Everything Beyond 200 nm Is Under ISA

Incorrect.

An extended continental shelf can extend beyond 200 nm.

Mistake 6: ISA Is a Commercial Mining Company

Incorrect.

Its principal function is international organisation, regulation and control.

Mistake 7: Any Company Can Mine the Area

Incorrect.

Activities must operate within the UNCLOS/ISA framework.

Mistake 8: Discovery Creates Ownership

Incorrect.

Article 137 prohibits appropriation.

Mistake 9: Sponsoring State Is Automatically Liable for Every Contractor Act

Incorrect.

The 2011 Advisory Opinion focuses on due diligence obligations.

Mistake 10: Common Heritage Means Free Exploitation

Incorrect.

It means international regulation and benefit for mankind as a whole.

Mistake 11: ISA and CLCS Perform the Same Function

Incorrect.

ISA regulates activities in the Area; CLCS deals with the scientific and technical aspects of outer continental-shelf limits.

Conclusion

The International Seabed Authority is the central institutional mechanism for implementing the Common Heritage of Mankind regime established by UNCLOS for the deep seabed beyond national jurisdiction.

Under Article 156, the ISA is established to organise and control activities in the Area. Its authority is not based on territorial sovereignty; rather, it is an international regulatory authority operating within the legal framework of Part XI of UNCLOS.

The most important substantive principles underlying its work are:

Article 136 → Common Heritage of Mankind

Article 137 → No National Appropriation

Article 140 → Benefit of Mankind

Article 145 → Environmental Protection

The ISA regulates activities such as:

  • prospecting;
  • exploration;
  • exploitation;

through mechanisms including plans of work, contracts, regulations and compliance requirements.

Its principal organs include the Assembly, Council, Secretariat and specialised bodies such as the Legal and Technical Commission and Finance Committee, while the Enterprise is established as an organ under Article 170.

The 1994 Implementation Agreement is essential because it modified important elements of the original Part XI regime and shaped the modern operation of the ISA.

Environmental protection is now one of the most significant aspects of seabed governance. The ISA must balance the potential economic value of deep seabed minerals with the obligation to protect fragile marine ecosystems.

The 2011 Seabed Disputes Chamber Advisory Opinion on sponsoring States is particularly important for understanding the responsibilities of States sponsoring entities engaged in activities in the Area, especially the obligation of due diligence.

The most important distinction to remember is:

ISA → Area

Coastal State → Continental Shelf

IMO → International Shipping

ITLOS → Dispute Settlement

CLCS → Outer Continental-Shelf Limits

Ultimately:

The International Seabed Authority converts the Common Heritage of Mankind principle into an institutional system for regulating deep seabed activities for the benefit of mankind as a whole while protecting the marine environment.

For examination purposes, remember:

156 – 159 – 161 – 165 – 166 – 170

156 → Establishment

159 → Assembly

161 → Council

165 → Legal & Technical Commission

166 → Secretariat

170 → Enterprise

And:

136 – 137 – 140 – 145

Common Heritage → No Appropriation → Benefit of Mankind → Environment
