MARITIME LAW

PRINCIPLE
1. Principle of Freedom
This principle ensures that certain parts of the ocean, particularly the high seas, remain open
to all nations, without any single nation claiming sovereignty. Key freedoms include:
 Navigation: All states, whether coastal or landlocked, have the right to navigate
vessels under their flags on the high seas.
 Overflight: Aircraft can fly freely over the high seas.
 Laying Submarine Cables and Pipelines: This promotes global communication.
 Fishing and Marine Research: These activities are unrestricted, but subject to
conservation and management measures.
The principle underscores non-sovereignty, ensuring the oceans remain a global commons.

2. Principle of Sovereignty
This principle applies primarily to a coastal state’s territorial sea, which extends up to 12
nautical miles from its baseline. It grants the coastal state:
 Complete jurisdiction over resources (fisheries, minerals, and hydrocarbons).
 Authority to regulate maritime activities such as shipping and environmental
preservation within this zone.
 Enforcement rights for customs, taxation, immigration, and pollution laws.
However, foreign vessels retain the right of innocent passage, provided they do not threaten
the coastal state’s security.

3. Principle of the Common Heritage of Mankind

This principle is central to the governance of areas beyond national jurisdiction, such as the
seabed (called "The Area") and its resources. It emphasizes:
 Equitable resource sharing among all states, regardless of technological or financial
capabilities.
 Preservation of these resources for future generations.
 Regulatory oversight by the International Seabed Authority (ISA) to prevent over-
exploitation.
This principle contrasts with the freedom of the seas, focusing on collective ownership and
stewardship.
4. Principle of Equity
Equity plays a critical role in maritime delimitation disputes between states, particularly
concerning overlapping claims over maritime boundaries. Courts and tribunals apply
equitable principles to:
 Resolve disputes in a fair manner, accounting for geographical peculiarities and
economic dependencies.
 Balance predictability in legal outcomes with flexibility to address unique
circumstances.
The corrective-equity approach ensures fairness without rigid adherence to distance or
proportion.

5. Humanitarian Considerations
Maritime law incorporates protections for human rights and humanitarian concerns at sea:
 Search and Rescue: Coastal states and ships have obligations to assist vessels or
persons in distress.
 Fair Treatment: Maritime disputes must ensure humane treatment of crew members
and avoid undue detention.
 ITLOS Rulings: Tribunals have reinforced the principles of due process and fairness
in handling maritime disputes and detentions.

6. Principle of Reciprocity and Cooperation

This principle emphasizes the interconnected nature of marine ecosystems and international
relations. It highlights:
 Cooperation for Sustainable Use: Shared responsibility for conserving living marine
resources and biodiversity.
 Environmental Protection: Collaborative efforts to mitigate marine pollution and
manage global resources.
 Maritime Security: Coordinated actions to address piracy, illegal fishing, and safety
issues on the high seas.

These principles together form the foundation of maritime law, ensuring that the ocean is
utilized sustainably and equitably, balancing the rights of individual states with the broader
interests of humanity. Let me know if you'd like further elaboration on any of these points!
Sources
The sources of maritime law, also referred to as the international law of the sea, are rooted in
formal and material sources. These sources establish the rules and principles that govern the
conduct of states and other entities over maritime matters. The following provides a detailed
overview:

1. Formal Sources
Formal sources determine the legal validity of maritime rules. According to Article 38(1) of
the Statute of the International Court of Justice (ICJ), the formal sources include:
a. Treaties and Conventions
 Treaties are agreements between states that establish rules and obligations. In
maritime law, key treaties include:
o The United Nations Convention on the Law of the Sea (UNCLOS) of 1982.

o Preceding treaties like the 1958 Geneva Conventions.

 Treaties provide clarity and codification, but they are binding only on the states that
are parties to them.
b. Customary International Law
Customary law evolves from the consistent and general practice of states, accepted as legally
binding (opinio juris). It can be categorized into:
 General Customary Law: Applicable universally to all states, including non-
signatories of specific treaties.
 Special or Local Customary Law: Applies to specific groups of states with shared
practices, such as diplomatic asylum in Latin America.
 Customary law is significant where treaties do not exist or in cases involving non-
party states.
c. General Principles of Law
These principles are recognized by "civilized nations" and serve as a safety net to prevent
gaps in international law. While they hold limited value in maritime contexts, they reinforce
fundamental concepts such as fairness and equity.
d. Judicial Decisions and Scholarly Writings
 Judicial decisions, particularly from the ICJ and International Tribunal for the Law of
the Sea (ITLOS), clarify and consolidate rules.
  The writings of prominent legal scholars are considered subsidiary sources for
interpreting maritime law.

2. Material Sources
Material sources provide the substantive content and evidence of legal rules.
a. Judicial Decisions
Judicial decisions play a critical role in:
 Identification of Rules: Establishing the existence of customary or treaty-based rules.
 Clarification: Interpreting ambiguous legal provisions.
 Consolidation: Reinforcing established norms through consistent application.
 Formation of New Rules: Judicial decisions influence the development of maritime
law, especially in boundary delimitation cases.
b. State Practices
State actions, such as diplomatic correspondence, national laws, and official statements,
provide evidence of established or emerging customary rules. Uniformity and consistency in
state practices are essential for developing customary law.
c. Contributions of International Organizations
Organizations like the International Maritime Organization (IMO) and the International
Seabed Authority (ISA) contribute through specialized agreements, technical standards, and
regulatory frameworks that supplement UNCLOS.

3. Evolution of Sources
The sources of maritime law have evolved alongside international legal systems. The
codification efforts in the 20th century, particularly through UNCLOS, have integrated
diverse practices and principles into a unified legal framework.

Conclusion
The sources of maritime law combine formal rules from treaties, customs, and general
principles with the substantive content from state practices, judicial decisions, and scholarly
contributions. These collectively ensure the adaptability and enforceability of the legal
framework governing the world's oceans. Let me know if you'd like additional elaboration on
any of these sources!
Concept
The concept of maritime law encapsulates the legal principles, rules, and frameworks that
govern the use and management of the seas and oceans. It is derived from historical, legal,
and practical considerations that have evolved to balance the rights and responsibilities of
states and individuals over maritime spaces. Below is a detailed explanation based on the
information from the document provided.

1. Definition and Historical Evolution

 Maritime law, also known as the law of the sea, encompasses international rules that
regulate the rights and responsibilities of states in maritime environments.
 Historically, the concept emerged to manage issues such as navigation, territorial
claims, resource exploitation, and dispute resolution over oceanic waters.
 Ancient practices, Roman legal principles (jus naturale), and doctrines like Mare
Liberum (the freedom of the seas) played foundational roles in shaping contemporary
maritime law.

2. Scope and Jurisdictional Frameworks

Maritime law is characterized by its application to distinct maritime zones:
a. Territorial Sea
 Extends up to 12 nautical miles from the baseline of a coastal state.
 Coastal states exercise sovereignty over this zone but must allow innocent passage for
foreign vessels.
b. Exclusive Economic Zone (EEZ)
 Covers up to 200 nautical miles from the baseline.
 Coastal states have special rights to exploit marine resources, but freedom of
navigation and overflight remain preserved for other states.
c. High Seas
 Beyond national jurisdiction, the high seas are open to all states and governed by
principles of freedom, including navigation and resource use.
d. Continental Shelf
 Pertains to the seabed and subsoil extending beyond the EEZ.
 States have rights over natural resources on their continental shelves, regardless of the
superjacent waters being part of the high seas.
e. The Area
 Refers to the seabed and ocean floor beyond national jurisdiction.
 Governed under the principle of the common heritage of mankind, with equitable
resource-sharing facilitated by international mechanisms.

3. Principles Underpinning Maritime Law

Maritime law is built upon several key principles:
a. Freedom of Navigation
 Ensures unrestricted access to the high seas for all states, critical for international
trade and communication.
b. Sovereignty
 Coastal states have sovereign rights over their territorial seas, including the
management of resources and environmental protection.
c. Common Heritage of Mankind
 Applicable to resources in the Area, emphasizing equitable use and sustainable
management for the benefit of all humanity.
d. Cooperation and Reciprocity
 Encourages states to work together on issues like environmental protection, search
and rescue, and combating piracy.

4. Key Legal Instruments

The foundational treaties and conventions that constitute maritime law include:
 United Nations Convention on the Law of the Sea (UNCLOS): Often termed the
"Constitution of the Oceans," UNCLOS codifies the primary legal framework
governing the use of maritime spaces.
 Geneva Conventions on the Law of the Sea (1958): Precursor treaties to UNCLOS,
addressing territorial seas, continental shelves, and fishing rights.

5. Emerging Issues and Adaptation

Maritime law evolves to address contemporary challenges such as:
 Climate change impacts on maritime zones.
 Marine environmental degradation.
  Technological advancements in resource extraction.
 Disputes over maritime boundaries.

Conclusion
Maritime law provides a robust framework to balance the interests of individual states with
those of the global community. Its evolution reflects a continuous effort to harmonize
sovereignty, freedom, and cooperation in the use and governance of the world's oceans. If
further detail on specific zones or principles is needed, feel free to ask!
Here is a detailed discussion on the law governing the high seas, structured under the
requested subheadings:
 LAW OF HIGH SEAS
a) Doctrine of Freedom on High Seas
The doctrine of freedom of the high seas is a fundamental principle of international maritime
law. Key aspects include:
1. Historical Context:
o The concept traces back to the early 17th century and is attributed to Hugo
Grotius' "Mare Liberum" (1609), which opposed claims of sovereignty over
vast ocean spaces by individual nations.
o It asserts that the high seas are open for navigation and use by all states, not
subject to appropriation by any single state.
2. Legal Codification:
o Article 2 of the 1958 Geneva Convention on the High Seas states that the high
seas are open to all nations and cannot be claimed as part of any state's
sovereignty.
o Article 89 of the UNCLOS reinforces this by declaring that no state may
subject any part of the high seas to its sovereignty.
3. Implications of Freedom:
o Ensures equal access for all states, whether coastal or landlocked.

o Encourages peaceful uses such as navigation, trade, scientific research, and

laying of cables.

b) Definition of High Seas

The high seas are defined under international law as:
1. Scope:
o As per Article 86 of the UNCLOS, the high seas refer to "all parts of the sea
that are not included in the exclusive economic zone (EEZ), in the territorial
sea, or in the internal waters of a state, or in the archipelagic waters of an
archipelagic state".
2. Spatial Boundaries:
o Landward boundary: Determined by the outer limits of the territorial sea or
EEZ.
o Seaward boundary: Extends beyond the jurisdiction of any single state,
covering waters above the Area (seabed and ocean floor beyond national
jurisdiction).
 3. Significance:
o Represents the largest area of the world’s oceans, not subject to any state’s
exclusive jurisdiction, ensuring it remains a global commons.

c) Freedoms of the High Seas (In Greater Detail)

The freedoms of the high seas are enshrined in Article 87 of UNCLOS and are fundamental
to the global commons principle. These freedoms apply equally to all states, whether coastal
or landlocked, and must be exercised with due regard for the interests of other states and for
the conservation of marine resources.
1. Freedom of Navigation
o All states have the right to navigate ships flying their flags on the high seas.

o Ships must comply with international standards regarding safety,

environmental practices, and flag-state regulations.
o This freedom is crucial for global trade, connecting nations and economies.

2. Freedom of Overflight
o Aircraft are allowed to fly freely over the high seas, provided they respect
international aviation standards.
o This freedom is essential for international air travel and commerce, ensuring
unobstructed movement.
3. Freedom to Lay Submarine Cables and Pipelines
o States are permitted to lay and maintain submarine cables and pipelines.

o Such activities are regulated to avoid interference with existing cables,

pipelines, and marine ecosystems.
o This freedom facilitates international communication and energy distribution
systems.
4. Freedom of Fishing
o States have the right to fish on the high seas, but this is subject to international
conservation and management measures to prevent overfishing.
o Regional Fisheries Management Organizations (RFMOs) play a critical role in
sustainable resource use.
5. Freedom of Scientific Research
o States can conduct marine scientific research to explore and understand ocean
environments.
 o Research must respect international guidelines and cannot infringe upon the
rights of other states or marine ecosystems.
6. Freedom to Construct Artificial Islands and Installations
o Limited to compliance with international law, including safety regulations and
navigation rights.
o The construction must not harm the marine environment or interfere with
lawful uses of the high seas.

d) Jurisdiction of the High Seas

The high seas are beyond the jurisdiction of any single state, but international law provides a
framework for ensuring order, safety, and environmental protection. The principle of flag-
state jurisdiction and specific exceptions govern activities on the high seas:
1. Exclusive Flag-State Jurisdiction
 Vessels operating on the high seas fall under the exclusive jurisdiction of the state
whose flag they fly.
 The flag state is responsible for enforcing international and national laws on its
vessels, including safety, environmental, and labor standards (Article 92 of
UNCLOS).
 A ship without a flag (stateless ship) is considered in violation of international law.
2. Exceptions to Exclusive Jurisdiction
Certain situations allow states to act against vessels on the high seas:
a. Right of Visit (Article 110)
 Warships may stop and inspect a vessel if there are reasonable grounds to suspect:
o Piracy.

o Slave trade.

o Unauthorized broadcasting.

o The ship is stateless.

o The ship is flying a false flag.

 This ensures that illegal activities do not go unchecked.

b. Right of Hot Pursuit (Article 111)
 Coastal states may pursue vessels that violate their laws within territorial seas, EEZ,
or contiguous zones.
  Pursuit must commence while the vessel is within the state's jurisdiction and continue
uninterrupted onto the high seas.
 Hot pursuit ends when the ship enters the territorial sea of another state.
3. Conservation and Management Obligations
 States have a shared responsibility to conserve living marine resources and maintain
biodiversity.
 Agreements like the UN Fish Stocks Agreement and RFMOs regulate the use of
migratory species and fisheries.
4. Enforcement of International Rules
 The International Maritime Organization (IMO) oversees compliance with safety and
environmental standards.
 The flag state is obligated to ensure its vessels adhere to international treaties like
MARPOL (prevention of pollution) and SOLAS (safety of life at sea).
5. Suppression of Illegal Activities
States cooperate to combat:
 Piracy: UNCLOS defines piracy as any illegal act of violence, detention, or
depredation committed for private ends on the high seas. All states can apprehend
pirates and prosecute them under their national laws.
 Drug Trafficking: International frameworks enable interdiction and prosecution of
vessels involved in the transport of illicit drugs.
 Unauthorized Broadcasting: Measures exist to address illegal broadcasts from ships
on the high seas.
6. Environmental Protections
 States must prevent and control marine pollution under international agreements like
UNCLOS and MARPOL.
 The precautionary principle is applied to mitigate environmental risks from high-seas
activities.

Conclusion
The high seas represent the largest maritime area and require robust legal principles to ensure
their peaceful and sustainable use. Freedoms like navigation and fishing promote global
commerce and resource utilization, while jurisdictional mechanisms ensure order,
environmental protection, and the suppression of illegal activities. This framework balances
freedom with responsibility, reflecting the evolving needs of international maritime
governance.
Concept of Territorial Sea
1. The territorial sea is a maritime zone directly adjacent to a coastal state’s land territory
and internal waters. It is defined as extending up to 12 nautical miles from the
baseline, which is generally the low-water line along the coast. The concept of the
territorial sea establishes a zone where the coastal state exercises sovereignty, similar
to its control over its land territory. This sovereignty extends to the seabed, subsoil,
and airspace above the territorial sea.
2. The legal framework governing the territorial sea is codified in the United Nations
Convention on the Law of the Sea (UNCLOS). It provides a standardized definition
and scope for the territorial sea, balancing the rights of coastal states with
international obligations.
3. Historically, the breadth of the territorial sea was limited to the "cannon-shot" rule,
approximately 3 nautical miles, based on the range of coastal defense cannons.
Modern international law expanded this limit to 12 nautical miles to account for
advancements in technology and the growing need for uniformity in maritime
governance.
4. The concept also incorporates the baseline as the starting point for measuring the
territorial sea, which may involve straight baselines in specific cases, such as across
bays or around archipelagos. This ensures clarity in maritime delimitation while
addressing unique geographic features.

Definition of Territorial Sea

1. Legal Scope:
o The territorial sea extends up to 12 nautical miles from the baseline of a
coastal state.
o Sovereignty in this zone includes the seabed, subsoil, airspace above it, and
the water column.
2. Historical Evolution:
o Early practices limited this zone to a “cannon-shot” range, roughly 3 nautical
miles, which was later expanded in modern conventions.
o The United Nations Convention on the Law of the Sea (UNCLOS) codifies
the current framework.
3. Baselines:
o The baseline is the low-water line along the coast, from which the breadth of
the territorial sea is measured.
o Special provisions apply for bays, rivers, and archipelagos, which allow for
drawing straight baselines in specific conditions.
Rights of the Coastal State in the Territorial Sea
The coastal state exercises sovereignty in the territorial sea, subject to specific limitations
under international law.
1. Full Sovereignty:
o The coastal state has exclusive rights to regulate navigation, enforce customs,
taxation, immigration, and environmental laws.
o Sovereignty extends to natural resources, both living and non-living, within
the territorial sea.
2. Enforcement Jurisdiction:
o Coastal states can arrest vessels and impose penalties for breaches of their
laws within the territorial sea.
o This includes pollution control, illegal fishing, and smuggling.

Duties of the Coastal State in the Territorial Sea

Coastal states must exercise their rights without infringing upon international obligations:
1. Respect for Innocent Passage:
o Ships from other states enjoy the right of innocent passage, defined as
navigation through the territorial sea without harming the coastal state’s peace,
security, or environment.
o The coastal state may suspend innocent passage temporarily for security
reasons.
2. Compliance with International Standards:
o The coastal state must adhere to international conventions such as MARPOL
for pollution control and SOLAS for navigation safety.
3. Protection of Marine Environment:
o States must protect and preserve the marine environment in the territorial sea,
aligning with global conservation efforts.

Conclusion
The territorial sea embodies a balance between the sovereignty of coastal states and the rights
of other states, particularly through the principle of innocent passage. The UNCLOS
framework ensures that this balance is maintained while addressing contemporary challenges
in marine governance.

b) Contiguous Zones
The contiguous zone is a marine area adjacent to the territorial sea where a coastal state can
exercise limited control to enforce its laws. It is governed by Article 33 of the United Nations
Convention on the Law of the Sea (UNCLOS).
1. Definition and Legal Framework:
o The contiguous zone extends up to 24 nautical miles from the baseline of the
coastal state, measured from the outer limit of the territorial sea.
o Its primary purpose is to enable the coastal state to prevent or punish
infringements of its customs, fiscal, immigration, or sanitary laws and
regulations within its territory or territorial sea.
2. Jurisdiction and Enforcement:
o The coastal state’s authority in the contiguous zone includes enforcement but
not legislative jurisdiction.
o This means the coastal state cannot impose laws directly applicable to
activities in the contiguous zone but can take action to enforce its existing
laws.
3. Historical Development:
o The concept originated from the Hovering Acts of 18th-century Great Britain,
which sought to regulate smuggling and other illegal activities.

c) Straits
Straits are narrow waterways connecting two larger bodies of water and are often used for
international navigation. The legal regime governing straits depends on their classification
under UNCLOS.
1. Definition and Classification:
o Straits are categorized as either:

 Straits where transit passage applies: These are used for

international navigation connecting one part of the high seas or EEZ to
another (e.g., Dover Strait).
 Straits where innocent passage applies: Such as the Messina Strait,
where non-suspendable innocent passage applies.
 2. Rights and Duties of States:
o Coastal states may regulate transit passage to ensure safety and environmental
protection but cannot suspend it.
o Passage must be continuous and expeditious, allowing for navigation without
threats to the peace, good order, or security of the coastal state.
3. Transit Passage vs. Innocent Passage:
o Transit passage allows for navigation and overflight without restrictions,
applicable in strategic international straits.
o Innocent passage applies to ships transiting through straits within the
territorial sea, ensuring that their passage does not threaten the coastal state.

d) Baseline – Archipelagic States

Archipelagic baselines are unique to states consisting of a chain of islands. UNCLOS grants
specific provisions to such states to determine their maritime boundaries.
1. Definition and Requirements:
o Archipelagic baselines join the outermost points of the outermost islands,
forming the basis for defining territorial seas and other maritime zones.
o Conditions for drawing baselines include:

 The water-to-land ratio must be between 1:1 and 9:1.

 Baselines cannot exceed 100 nautical miles, with up to 3% allowed to
extend up to 125 nautical miles.
2. Sovereignty and Rights:
o Archipelagic states have sovereignty over waters enclosed by baselines,
including their airspace, seabed, and subsoil.
o Traditional fishing rights and international navigation rights (e.g., sea-lane
passage) must be respected.

e) Exclusive Economic Zone (EEZ)

The EEZ is a maritime zone beyond the territorial sea where a coastal state has special rights
regarding resource exploration and exploitation.
1. Definition and Scope:
o Extends 200 nautical miles from the baseline.
 o Includes the water column, seabed, and subsoil.

2. Rights of the Coastal State:

o Sovereign rights for the purpose of exploring and exploiting natural resources.

o Jurisdiction over artificial islands, marine scientific research, and

environmental protection.
3. Obligations of the Coastal State:
o Respect freedoms of navigation, overflight, and the laying of submarine cables
and pipelines by other states.
4. Significance and Challenges:
o The EEZ allows states to balance economic development with environmental
conservation.
o Disputes may arise over overlapping claims between neighboring states.
