1. Introduction

Ocean Resource Governance Claims in Thailand concern the legal rights, duties, liabilities, and remedies arising from the management, conservation, exploitation, and protection of marine resources. These claims involve disputes between individuals, fishing communities, commercial enterprises, coastal developers, government authorities, and environmental organisations.

Thailand's marine resources are economically and environmentally important because of its extensive coastline along the Gulf of Thailand and the Andaman Sea. Marine governance therefore involves balancing:

Protection of marine biodiversity and coastal ecosystems.

Sustainable fisheries and aquaculture.

Rights of traditional and small-scale fishing communities.

Regulation of offshore petroleum and marine activities.

Prevention of marine pollution and destruction of coral reefs.

Compensation for environmental and economic damage.

Protection of public and community interests in marine resources.

Ocean resource governance claims have both public-law and civil-law dimensions. Administrative authorities regulate marine activities, while civil courts may address private rights, unlawful conduct, compensation, contractual obligations, and environmental damage.

2. Legal Framework Governing Ocean Resources in Thailand

A. Thai Civil and Commercial Code

The Thai Civil and Commercial Code provides the general framework for civil liability and private disputes involving marine resources.

Important provisions include:

Section 420 – Tortious liability

A person who wilfully or negligently unlawfully injures another person's life, body, health, liberty, property, or rights may be liable to compensate the injured person.

Applications include:

Destruction of fishing equipment.

Damage to private coastal property.

Pollution affecting commercial fishing operations.

Negligent marine construction.

Interference with legally protected economic interests.

Section 421 – Abuse of rights

The exercise of a right that is intended solely to cause injury to another person may constitute an unlawful act.

This provision may become relevant where marine-resource rights are exercised abusively.

Section 438 – Assessment of damages

The court determines the manner and extent of compensation according to the circumstances and gravity of the wrongful act.

Section 443 – Death and bodily injury

This provision addresses compensation arising from death and bodily injury, potentially relevant to accidents involving fishing vessels, offshore operations, and marine pollution.

B. Enhancement and Conservation of National Environmental Quality Act B.E. 2535 (1992)

This legislation establishes Thailand's principal environmental protection framework.

It is relevant to:

Marine pollution.

Coastal ecosystem degradation.

Wastewater discharge.

Environmental quality standards.

Environmental impact assessment.

Liability for environmental damage.

Section 96 is particularly important because it provides liability for damage caused by pollution originating from a source that causes injury to another person's life, body, health, or property.

Section 97 addresses compensation for damage to natural resources owned by or belonging to the State.

C. Marine and Coastal Resources Management Promotion Act B.E. 2558 (2015)

This legislation provides a framework for conserving and managing marine and coastal resources.

It addresses:

Marine ecosystem protection.

Coastal-resource conservation.

Protection of vulnerable habitats.

Community participation.

Restrictions on harmful activities.

Restoration of damaged marine resources.

D. Fisheries Act B.E. 2558 (2015)

The Fisheries Act regulates fishing activities and the sustainable utilisation of aquatic resources.

It covers:

Commercial fishing licences.

Fishing gear restrictions.

Marine conservation zones.

Illegal, unreported and unregulated fishing.

Protection of aquatic species.

Fishing-community interests.

Its regulatory provisions can become relevant in civil disputes involving unlawful fishing, economic losses, and damage to marine resources.

E. Other Relevant Legislation

Additional laws that may govern ocean resource disputes include:

National Park Act B.E. 2562 (2019): Protection of marine national parks and restrictions on damaging activities.

Navigation in Thai Waters Act B.E. 2456 (1913): Regulation of navigation and activities affecting navigable waters.

Thai Vessels Act B.E. 2481 (1938): Registration and legal regulation of Thai vessels.

Oil Pollution Act B.E. 2560 (2017): Relevant to liability and compensation for oil pollution from ships.

Constitution of Thailand B.E. 2560 (2017): Recognises duties concerning natural-resource conservation, environmental protection, and public participation, particularly under Sections 43 and 57.

3. Major Types of Ocean Resource Governance Claims

A. Marine Pollution and Environmental Damage Claims

Marine pollution is one of the most important areas of ocean-resource litigation.

Pollution may arise from:

Oil spills from commercial vessels.

Industrial wastewater discharge.

Offshore petroleum operations.

Plastic and chemical waste.

Shipping accidents.

Destruction of marine habitats.

Affected fishing communities, property owners, and other legally entitled claimants may seek compensation under applicable civil and environmental legislation.

A claimant generally needs to establish the relevant legal basis, the damage suffered, and the causal connection between the defendant's conduct and the damage.

B. Traditional Fishing Rights Claims

Traditional fishing communities may depend on coastal waters for their livelihood and cultural practices.

Disputes can arise when:

Commercial fishing companies operate in restricted areas.

Coastal development blocks access to fishing grounds.

Government authorities impose fishing restrictions.

Marine construction damages traditional fishing locations.

Illegal fishing reduces fish populations.

The legal issues include access rights, lawful fishing entitlements, administrative decision-making, community participation, and compensation for demonstrable losses.

C. Coastal Development and Marine Infrastructure Claims

Infrastructure projects such as ports, jetties, marinas, seawalls, and offshore facilities may affect marine ecosystems.

Civil and administrative claims can concern:

Unlawful construction or licensing.

Damage to fishing grounds.

Interference with coastal property.

Failure to undertake proper environmental assessments.

Loss of income.

Failure to restore damaged marine environments.

D. Marine Biodiversity and Conservation Claims

Marine biodiversity includes coral reefs, mangroves, seagrass beds, marine mammals, and threatened aquatic species.

Claims may arise where private operators or public authorities fail to protect these resources.

Possible remedies include:

Injunctions against harmful activities.

Environmental restoration.

Compensation for property and livelihood losses.

Recovery of statutory natural-resource damages.

Judicial review of unlawful administrative decisions.

E. Offshore Energy and Resource Extraction Claims

Offshore oil, natural gas, and other marine resource activities may generate disputes concerning:

Environmental damage.

Licence conditions.

Negligent offshore operations.

Damage to fishing communities.

Pipeline construction.

Vessel accidents.

Contractual allocation of environmental risks.

Such disputes may involve operators, contractors, vessel owners, insurers, regulators, and affected communities.

4. Important Thai Judicial Decisions and Case Laws

The following decisions provide judicial principles relevant to ocean resource governance. An important distinction is that some are directly concerned with coastal or marine resources, while others concern freshwater or general environmental protection and are used as analogous authorities.

Case 1. Sakom Coastal Fishing and Jetty Dispute – Supreme Administrative Court Order No. 630/2551 (2008)

Court: Supreme Administrative Court of Thailand.

Subject: Coastal development, traditional fishing interests, and environmental restoration.

Facts:

Fishermen operating around the Sakom coastal area challenged the approval and construction of jetties near the mouth of Sakom Canal.

They alleged that the construction damaged the coastal environment and adversely affected their fishing activities and income.

The fishermen requested suspension of the activities, compensation for their economic losses, and restoration of the coastal environment.

Legal issues:

Whether fishermen had standing to challenge administrative conduct affecting coastal resources.

Whether interference with fishing livelihoods could support a compensation claim.

Whether environmental restoration could be claimed independently of individual economic compensation.

Whether limitation periods applied differently to different remedies.

Decision:

The Supreme Administrative Court accepted the fishermen's cause of action concerning alleged wrongful administrative conduct.

It held that their claims for income and other individual economic losses were subject to a one-year limitation period applicable to the relevant administrative wrongful-act claim.

The restoration claim, concerning protection of public environmental interests, was not barred in the same manner.

However, the fishermen could not claim compensation on behalf of the Department of Marine and Coastal Resources without its authority.

Legal principles:

Fishing livelihoods can constitute legally protectable interests.

Coastal development may be challenged where it unlawfully affects affected communities.

Environmental restoration and personal compensation are distinct remedies.

Individuals cannot automatically litigate monetary claims belonging to government agencies.

Relevance: This is one of the most directly relevant Thai decisions for ocean resource governance because it concerns coastal infrastructure, fishing communities, administrative accountability, and environmental restoration.

Case 2. Maya Bay Environmental Protection Case – Supreme Court Judgment No. 5818/2549 (2006)

Court: Supreme Court of Thailand.

Subject: Marine tourism, coastal environmental protection, and restoration.

Facts:

The dispute concerned environmental damage associated with activities undertaken at Maya Bay in Krabi Province.

Local administrative authorities and other claimants sought judicial intervention against activities alleged to have damaged the natural environment.

The proceedings raised questions concerning the legal authority of local administrations to protect natural resources and the ability of community members to bring environmental proceedings.

Legal issues:

Whether local administrative authorities could sue private entities for environmental damage.

Whether community members could independently claim standing.

Whether environmental restoration could be ordered.

Whether private activities authorised by public authorities could nevertheless result in environmental liability.

Decision:

The Supreme Court recognised that local administrative authorities had statutory duties to supervise and improve natural resources and the environment.

It accepted their authority to bring proceedings against private entities whose activities caused environmental damage within their jurisdiction.

However, the Court found that the individual claimants relying on the traditional-community provision of the 1997 Constitution lacked standing under the legal framework applicable at that time because the relevant concept had not been sufficiently defined through implementing legislation.

The Court allowed the environmental restoration claim to proceed for examination of the evidence.

Legal principles:

Local governments have legally recognised environmental protection responsibilities.

Environmental restoration is a legitimate judicial remedy.

Private entities may face legal proceedings for environmental damage.

Community standing depends on the applicable constitutional and statutory framework.

Relevance: The judgment is important for marine tourism, coral reef protection, coastal development, and the responsibilities of local authorities in conserving marine environments.

Case 3. Raw Sugar Cargo Ship Pollution Case – Supreme Court Judgment No. 6492/2559 (2016)

Court: Supreme Court of Thailand.

Subject: Water pollution, vessel accidents, scientific evidence, and natural-resource compensation.

Facts:

A cargo ship carrying raw sugar sank in the Chao Phraya River in the Ayutthaya and Ang Thong areas.

Sugar remaining in the vessel was pumped into the river following the accident.

The contamination resulted in fish deaths and environmental damage.

Government agencies, including the Pollution Control Department and Department of Fisheries, participated in proceedings seeking compensation.

Legal issues:

Whether the defendants were responsible for environmental damage resulting from the vessel incident.

Whether scientific evidence could establish the cause of fish deaths.

Whether investigation expenses were recoverable.

Whether natural-resource restoration costs could form part of compensation.

Decision:

The Supreme Court accepted scientific evidence establishing that the sugar contamination reduced oxygen availability in the water and caused fish mortality.

It distinguished the actual cause of the damage from alleged chemical pollution originating from other nearby factories.

The Court recognised the recoverability of direct environmental investigation expenses and natural-resource restoration costs.

Legal principles:

Scientific evidence is important in establishing environmental causation.

Environmental compensation can include reasonable investigation expenses.

Restoration costs may be recoverable.

The defendant's conduct must be connected to the particular environmental damage claimed.

Relevance: Although the incident occurred in a river rather than the sea, the decision provides an important framework for assessing pollution from marine cargo vessels, shipping accidents, and damage to aquatic resources.

Case 4. Klity Creek Lead Contamination Case – Supreme Court Judgment No. 15219/2558 (2015)

Court: Supreme Court of Thailand.

Subject: Environmental liability, natural-resource contamination, and community compensation.

Facts:

A lead-processing operation discharged contaminated wastewater and chemicals into Klity Creek.

Indigenous Karen villagers living downstream depended on the creek for water and everyday activities.

The contamination caused serious health consequences and affected the villagers' ability to work.

The affected villagers brought claims against the company and responsible managers.

Legal issues:

Whether the company was liable for pollution-related injuries.

Whether the responsible managers could also incur liability.

Whether villagers could recover compensation.

Whether environmental restoration could be ordered.

Which limitation period applied to the statutory environmental claim.

Decision:

The Supreme Court ordered compensation to the affected plaintiffs, with amounts reported at approximately THB 2–3 million per plaintiff.

It also ordered restoration of the contaminated creek.

The Court applied the environmental strict-liability framework under the Enhancement and Conservation of National Environmental Quality Act B.E. 2535.

Legal principles:

Environmental pollution may create statutory liability without requiring the claimant to establish ordinary negligence in the same manner as a conventional tort claim.

Communities dependent on natural resources may have legally protected interests.

Monetary compensation and ecological restoration can operate together.

Corporate operators and responsible managers may face legal consequences.

Relevance: Although it is a freshwater case, its principles are useful for marine contamination, toxic discharges, destruction of fishing resources, and pollution affecting coastal communities.

Case 5. Bueng Boraphet Water Pollution Case – Supreme Administrative Court Judgment No. A.204/2552 (2009)

Court: Supreme Administrative Court of Thailand.

Subject: Government liability, aquatic-resource protection, and wastewater discharge.

Facts:

A government fisheries research and development centre discharged untreated wastewater into a canal connected with Bueng Boraphet.

The discharge affected the surrounding water resources and caused harm and inconvenience to local residents.

The dispute concerned the responsibility of government agencies for failing to perform their environmental and fisheries-conservation duties properly.

Legal issues:

Whether government agencies have a duty to conserve aquatic resources.

Whether untreated wastewater discharge constituted wrongful administrative conduct.

Whether the responsible government department could be held liable.

Whether an order preventing further pollution could be granted.

Decision:

The Supreme Administrative Court found that the fisheries centre had acted contrary to its public duties and had negligently failed to manage wastewater appropriately.

The Department of Fisheries was held responsible for the wrongful conduct of its affiliated agency.

The Court upheld the prohibition against discharging wastewater without prior treatment.

Legal principles:

Government bodies must comply with environmental duties.

Public agencies can incur liability for negligent environmental administration.

Environmental protection obligations apply to government-operated facilities.

Preventive judicial remedies may be appropriate.

Relevance: This decision provides an analogous framework for government fisheries facilities, coastal research centres, marine aquaculture operations, and wastewater-management disputes.

Case 6. Map Ta Phut Environmental Protection Case – Supreme Administrative Court Order No. 592/2552 (2009)

Court: Supreme Administrative Court of Thailand.

Subject: Environmental impact assessment, industrial development, and preventive environmental justice.

Facts:

The Anti-Global Warming Association and residents of Map Ta Phut challenged approvals granted to numerous industrial, energy, and infrastructure projects.

They argued that the projects had proceeded without satisfying the environmental and health-protection procedures required by Article 67(2) of the 2007 Constitution.

Legal issues:

Whether constitutional environmental protections operated without additional implementing legislation.

Whether projects could continue despite procedural environmental deficiencies.

Whether courts could suspend projects before irreversible environmental damage occurred.

Whether public participation and environmental health assessments were legally required.

Decision:

The Supreme Administrative Court recognised that the constitutional environmental protections were immediately applicable.

It ordered the suspension of specified projects that could cause serious environmental harm until the legal proceedings were determined.

Legal principles:

Environmental protection is a constitutional concern.

Environmental impact assessment requirements must be respected.

Courts may grant preventive relief where serious environmental harm is threatened.

Public participation is an important part of environmental governance.

Relevance: The decision is applicable by analogy to coastal industrial facilities, offshore energy infrastructure, marine terminals, port development, and projects that may affect marine ecosystems.

5. Legal Principles Emerging from the Cases

The decisions discussed above establish several important principles for ocean resource governance.

6. Civil Remedies Available for Ocean Resource Governance Claims

A. Monetary Compensation

Individuals and businesses may claim compensation for legally recognised losses, including:

Loss of fishing income.

Damage to fishing vessels and equipment.

Damage to coastal property.

Personal injury caused by pollution.

Loss of aquaculture production.

Reasonable expenses incurred because of environmental damage.

B. Environmental Restoration

Where marine resources have been damaged, restoration may involve:

Rehabilitation of coral reefs.

Replanting mangrove forests.

Restoration of seagrass beds.

Removal of marine pollutants.

Rehabilitation of aquatic habitats.

Recovery of affected fish populations.

Section 97 of the Enhancement and Conservation of National Environmental Quality Act is particularly relevant to compensation for damage to natural resources belonging to the State.

C. Injunctions and Preventive Orders

Courts may grant appropriate preventive relief where the legal requirements are satisfied.

Examples include:

Stopping unlawful coastal construction.

Preventing untreated wastewater discharge.

Restricting harmful activities affecting protected ecosystems.

Suspending unlawful administrative approvals.

D. Administrative and Public-Law Remedies

Affected communities may challenge unlawful government decisions through administrative proceedings.

These claims may concern:

Invalid environmental approvals.

Failure to conduct required environmental assessments.

Unlawful fishing restrictions.

Failure to enforce conservation legislation.

Negligent management of public marine resources.

7. Important Challenges in Ocean Resource Governance Litigation

1. Difficulty establishing causation

Marine pollution frequently involves several possible sources. Claimants may struggle to establish which operator or activity caused the damage.

2. Scientific evidence

Coral reef destruction, chemical contamination, fish mortality, and biodiversity losses require technical and scientific evidence.

3. Community standing

Traditional fishing communities may face procedural difficulties in establishing their legal interest in marine resources.

4. Assessment of environmental damage

The economic value of marine biodiversity, ecological services, and long-term habitat destruction can be difficult to calculate.

5. Jurisdictional complexity

Ocean resource disputes may involve several regulatory authorities, private operators, local administrations, and national environmental institutions.

6. Long-term restoration

Monetary compensation alone may not restore marine ecosystems. Effective enforcement and continuing environmental monitoring are also necessary.

8. Emerging Issues in Thai Ocean Resource Governance

Future litigation is likely to involve increasingly complex technological and environmental issues.

9. Suggestions for Strengthening Thailand's Legal Framework

Thailand could strengthen ocean resource governance through the following measures:

1. Marine environmental liability: Improve the mechanisms for identifying responsible polluters and recovering environmental restoration costs.

2. Community participation: Strengthen procedural opportunities for traditional fishing communities to participate in marine-resource decisions.

3. Scientific assessment: Develop standardised procedures for evaluating marine ecosystem damage.

4. Corporate accountability: Improve environmental reporting and monitoring obligations for offshore operators.

5. Marine restoration funds: Establish effective mechanisms for financing restoration following shipping accidents and industrial pollution.

6. Digital monitoring: Use satellite imagery, artificial intelligence, and marine sensors to detect illegal fishing and pollution.

7. Cross-border cooperation: Improve cooperation with neighbouring countries concerning marine pollution and shared fisheries.

10. Conclusion

Civil Law and Ocean Resource Governance Claims in Thailand represent an important intersection of environmental protection, property interests, commercial responsibility, community rights, and public administration.

The Sakom Coastal Fishing Dispute and Maya Bay Environmental Protection Case provide particularly relevant judicial examples concerning coastal development, marine conservation, and fishing-community interests.

The Klity Creek, Bueng Boraphet, and Raw Sugar Cargo Ship decisions further demonstrate how Thai courts approach pollution liability, scientific evidence, compensation, and environmental restoration.

The central legal principle is that economic exploitation of marine resources must be consistent with environmental protection, lawful administration, and the legally recognised rights of affected communities.

Research qualification: Thailand is a civil-law jurisdiction, and its judgments should be examined in their statutory and factual context. The six decisions above are not all direct ocean-resource cases: the Sakom and Maya Bay cases concern coastal resources, while several others provide analogous environmental-liability principles. They should not be represented as six identical marine precedents.
