1. Introduction

Civil Law and Autonomous Space Infrastructure Governance in Thailand concerns the legal regulation of space-related infrastructure, satellite networks, autonomous spacecraft, launch facilities, orbital systems, ground stations, artificial intelligence (AI)-controlled space operations, and privately operated space technologies.

The subject examines how Thailand's civil-law system can regulate the ownership, operation, maintenance, financing, safety, liability, and governance of increasingly autonomous space infrastructure.

Space infrastructure is no longer limited to government-owned satellites. It increasingly involves private companies, international satellite operators, AI-powered monitoring systems, telecommunications networks, autonomous navigation, and commercial space services.

Thailand has important interests in this area through:

Geo-Informatics and Space Technology Development Agency (GISTDA).

National Space Policy Committee.

Thai satellite telecommunications infrastructure.

Earth-observation satellite systems.

National telecommunications and broadcasting infrastructure.

Satellite-based disaster management and environmental monitoring.

International space technology cooperation.

An important legal qualification is that, as of November 2026, Thailand's proposed Space Affairs Act remains a legislative project rather than an enacted comprehensive space statute. In August 2026, the National Space Policy Committee discussed advancing the legislation.

bde.go.th+2

Consequently, autonomous space infrastructure disputes must presently be examined through existing Thai civil, administrative, telecommunications, environmental, contractual, and international legal frameworks.

2. Meaning of Autonomous Space Infrastructure Governance

Autonomous Space Infrastructure Governance refers to the legal and institutional framework governing infrastructure that can operate, monitor, maintain, coordinate, or make operational decisions with limited human intervention.

Its principal components include:

A. Satellite infrastructure

Autonomous communication satellites.

Earth-observation satellites.

Satellite navigation networks.

Satellite-based internet infrastructure.

Autonomous satellite positioning systems.

B. Orbital infrastructure

Satellite constellation management.

Orbital collision avoidance.

Space debris monitoring.

Autonomous spacecraft positioning.

Satellite servicing and maintenance.

C. Ground infrastructure

Satellite control stations.

Space communication facilities.

Ground-based tracking stations.

Data processing centres.

Launch and recovery facilities.

D. Artificial intelligence infrastructure

AI-controlled satellite operations.

Autonomous anomaly detection.

Predictive satellite maintenance.

Automated orbital manoeuvres.

Algorithmic space traffic management.

E. Commercial infrastructure

Private satellite ownership.

Space infrastructure investment.

Satellite leasing arrangements.

Commercial launch services.

International infrastructure partnerships.

The central civil-law question is:

Who should bear legal responsibility when autonomous space infrastructure causes financial loss, property damage, personal injury, environmental harm, or disruption of essential services?

3. Applicable Legal Framework in Thailand

A. Thai Civil and Commercial Code

The Civil and Commercial Code (CCC) provides the foundational legal framework for private disputes involving space infrastructure.

Important provisions include:

Section 420: General tort liability

Section 420 is particularly important.

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

Application to autonomous space infrastructure:

A defective satellite may damage another operator's equipment.

An autonomous navigation system may perform an unsafe manoeuvre.

A ground station may negligently transmit incorrect control instructions.

A software developer may introduce a dangerous operational defect.

A satellite operator may fail to implement reasonable collision-avoidance procedures.

The claimant must establish the relevant wrongful conduct, damage, and causal connection.

Section 425: Employer liability

Where an employee causes damage while acting in the course of employment, the employer may be jointly liable under the statutory requirements.

This provision is relevant when satellite engineers, ground-station personnel, or operational employees negligently interfere with space infrastructure.

Section 437: Liability concerning controlled things

This provision may be relevant to damage caused by certain things or vehicles under another person's supervision or control.

Its application to satellites, launch vehicles, and autonomous equipment requires careful interpretation. It should not automatically be treated as a universal strict-liability rule for all space objects.

B. State Liability Act B.E. 2539 (1996)

The Liability for Wrongful Acts of Officials Act B.E. 2539 is relevant when public officials cause damage through the performance of governmental functions.

Section 5 generally places liability upon the relevant government agency for wrongful acts committed by officials in the performance of their duties.

Possible applications include:

Negligent government satellite-control operations.

Unlawful administrative approvals.

Improper management of public space infrastructure.

Failure to exercise statutory supervisory responsibilities.

Negligent administration of government-operated tracking facilities.

This legislation is important because Thailand's space infrastructure involves both governmental and commercial participants.

C. Telecommunications Business Act B.E. 2544 (2001)

Satellite telecommunications infrastructure also falls within the broader telecommunications regulatory environment.

Relevant issues include:

Satellite service licensing.

Telecommunications network operations.

Spectrum allocation.

Orbital-frequency coordination.

Service continuity.

Consumer protection.

Regulatory supervision.

The National Broadcasting and Telecommunications Commission (NBTC) has an important regulatory role.

D. Environmental Quality Promotion and Preservation Act B.E. 2535 (1992)

Space infrastructure may create environmental risks through:

Launch emissions.

Ground-station construction.

Hazardous materials.

Radiofrequency-related regulatory concerns.

Debris from launch operations.

Infrastructure-related land and coastal development.

Environmental assessment, prevention, and restoration obligations may become relevant depending on the nature and location of the project.

E. International Space Law

Thailand is a party to the 1967 Outer Space Treaty and the 1968 Rescue Agreement.

However, Thailand is not a party to the 1972 Liability Convention or the 1975 Registration Convention. Thailand has nevertheless voluntarily supplied registration information for its space objects to the United Nations.

กรมสนธิสัญญาและกฎหมาย+1

The following principles are particularly important:

Peaceful use of outer space.

Freedom of exploration and use.

International responsibility for national space activities.

State responsibility for governmental and non-governmental activities under Article VI.

Avoidance of harmful interference.

International cooperation.

Article VI of the Outer Space Treaty is especially important because private space activities require appropriate governmental authorization and continuing supervision.

4. Autonomous Space Infrastructure and Civil Liability

A. Satellite collision liability

Autonomous satellites may independently calculate orbital adjustments and avoid potential collisions.

However, algorithmic autonomy does not eliminate legal responsibility.

Consider a situation in which a Thai-operated satellite incorrectly calculates another satellite's orbital position and causes a collision.

Potentially responsible parties may include:

Satellite operators.

Satellite manufacturers.

Navigation software developers.

Maintenance contractors.

Ground-control service providers.

The claimant may pursue an appropriate contractual or tortious claim depending on the relationship between the parties.

B. AI-controlled satellite failures

AI systems may malfunction because of:

Incorrect training data.

Software defects.

Cyberattacks.

Sensor failures.

Incorrect environmental predictions.

Inadequate human supervision.

Under Thai law, the central question would be whether an identifiable person or legal entity acted wrongfully or negligently and whether that conduct caused legally compensable damage.

AI itself does not automatically become a separate civil-law person.

C. Space infrastructure property disputes

Disputes may concern:

Satellite ownership.

Ground-station land rights.

Equipment leasing.

Intellectual property.

Infrastructure financing.

Satellite replacement obligations.

Contractual rights over satellite capacity.

Thai property and contractual principles may apply to the relevant assets and agreements.

Importantly, outer space cannot be appropriated as national territory merely through occupation or use. Ownership of a satellite does not create ownership of its orbital position.

D. Cybersecurity and infrastructure interruption

An autonomous satellite network may be attacked through malicious software or unauthorized control signals.

Potential claims include:

Negligence.

Breach of contract.

Unlawful interference with property or rights.

Confidentiality breaches.

Compensation for service interruption.

Recovery of foreseeable economic losses.

Evidence concerning system logs, software versions, satellite telemetry, and control instructions may be essential.

5. Important Thai Case Laws and Judicial Decisions

Important qualification: Thailand does not have six established reported judgments directly deciding autonomous space infrastructure liability. The following six decisions and dispute precedents are relevant by analogy. Their principles may assist in analysing satellite infrastructure, public infrastructure, administrative supervision, environmental damage, and contractual responsibility.

Case 1. Thaicom 7 and Thaicom 8 Satellite Dispute

Directly relevant satellite dispute

Reference: Thai Arbitration Institute Black Case No. 97/2560 and Red Case No. 65/2565.

Decision: Arbitration award dated 29 September 2022.

Background:

The dispute involved the Ministry of Digital Economy and Society and Thaicom Public Company Limited.

The disagreement concerned whether Thaicom 7 and Thaicom 8 were satellites covered by the original domestic communications satellite operating agreement dated 11 September 1991.

The Ministry asserted that contractual obligations concerning satellite ownership, assets, revenue sharing, and insurance applied.

Thaicom maintained that the satellites operated under the NBTC licensing framework rather than the original concession agreement.

Decision:

The arbitral tribunal unanimously determined that Thaicom 7 and Thaicom 8 were not satellites covered by the original agreement and dismissed the Ministry's counterclaim.

A subsequent Central Administrative Court proceeding concerning the challenge to the award was also dismissed.

Gulf Space Technology+1

Legal principles:

Satellite infrastructure must be governed by clearly defined contractual obligations.

Governmental regulatory powers must be distinguished from contractual rights.

Satellite replacement obligations depend on the agreement's actual terms.

Licensing arrangements can operate independently of earlier concession agreements.

Ownership and asset-transfer obligations require contractual interpretation.

Application to autonomous space infrastructure:

This dispute is particularly important when Thailand develops autonomous satellite constellations.

Contracts should expressly identify:

Ownership of autonomous satellites.

Replacement responsibilities.

AI software ownership.

Satellite control rights.

Insurance obligations.

Operational continuity requirements.

Liability for autonomous failures.

It is the strongest directly relevant Thai satellite dispute in this analysis, although the arbitration award is not a Supreme Court judgment.

Case 2. Maya Bay Environmental Protection Case

Reference: Supreme Court Judgment No. 5818/2549.

Date: 21 September 2006.

Background:

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

Local administrative authorities and community-related claimants pursued proceedings concerning environmental damage caused by private activities and the involvement of public authorities.

Decision:

The Supreme Court recognised the authority of local administrative bodies to bring proceedings to protect natural resources and the environment within their jurisdiction.

The Court also addressed limitations concerning the standing of individual traditional-community claimants under the constitutional framework applicable at that time.

The matter was returned for further consideration of the requested environmental restoration.

InforMEA

Legal principles:

Environmental protection is a legally recognised public interest.

Local administrative authorities may have standing to protect environmental resources.

Private activities causing environmental harm may attract legal proceedings.

Restoration can be an important form of remedy.

Application to space infrastructure:

If the construction of a satellite ground station, launch facility, or associated infrastructure damages protected environmental resources, affected public authorities may have grounds to pursue appropriate proceedings.

This case supports environmental accountability in infrastructure development.

Case 3. Mae Moh Environmental Pollution Case

Reference: Supreme Administrative Court Judgments Nos. A.749–764/2557.

Date: 23 December 2014.

Background:

The dispute involved the Electricity Generating Authority of Thailand's Mae Moh coal-mining operations.

Residents alleged that environmental violations and failures of regulatory supervision caused damage to their health, lives, and property.

Decision:

The Supreme Administrative Court found certain failures to comply with environmental requirements and ordered corrective measures, including environmental restoration and relocation of people from dangerous areas.

However, the Court distinguished environmental regulatory violations from individual tort claims.

For compensation based on tort, the claimants still had to establish the necessary causal relationship between the wrongful conduct and the particular damage claimed.

InforMEA+1

Legal principles:

Environmental compliance is legally significant.

Public authorities must perform their supervisory duties.

Environmental restoration may be ordered.

Individual compensation requires proof of causation.

Regulatory breaches and civil liability are distinct legal questions.

Application to autonomous space infrastructure:

Suppose a satellite launch facility causes environmental damage to surrounding communities.

The operator may face environmental corrective obligations, while individuals seeking personal compensation may additionally need to establish causation and damage.

The same reasoning is relevant to defective autonomous infrastructure that produces environmental harm.

Case 4. Racha Thewa Waste Disposal and Environmental Licensing Case

Reference: Supreme Administrative Court Judgment No. A.79/2547.

Date: 8 October 2004.

Background:

The dispute involved a private waste-disposal operator and public authorities responsible for regulating the disposal facility.

The authorities were challenged for issuing approvals without satisfying applicable environmental assessment requirements and for failing to supervise the operation adequately.

Decision:

The Supreme Administrative Court found that relevant public authorities had neglected their legal duties.

The Court ordered revocation of the unlawful licence, with a delayed effective date to avoid disrupting the public service immediately.

Judicial Portal

Legal principles:

Administrative licensing must comply with statutory requirements.

Regulatory authorities cannot disregard mandatory environmental procedures.

Public-service continuity can be considered when determining remedies.

Unlawful administrative approvals may be judicially reviewed.

Application to autonomous space infrastructure:

Thailand's proposed space legislation is expected to establish a more comprehensive licensing and supervisory framework.

The decision provides an important analogy for satellite launch facilities, ground stations, and commercial space infrastructure requiring regulatory permission.

An operator should not be permitted to bypass environmental and technical approval requirements simply because its infrastructure uses autonomous technology.

Case 5. Sakom Coastal Jetty Infrastructure Dispute

Reference: Supreme Administrative Court Order No. 630/2551.

Date: 3 October 2008.

Background:

Fishermen in the Sakom coastal area challenged the construction of jetties near the mouth of Sakom Canal.

They alleged that the infrastructure caused environmental damage and affected their fishing activities and livelihoods.

They sought suspension of activities, compensation, and restoration of the coastal environment.

Decision:

The Supreme Administrative Court recognised the claim concerning allegedly wrongful exercises of administrative authority.

It also addressed the limitation period for compensation claims and distinguished those claims from public-interest environmental restoration proceedings.

InforMEA

Legal principles:

Infrastructure projects may affect the livelihood of surrounding communities.

Public authorities can be challenged for unlawful exercises of power.

Compensation and environmental restoration may involve different limitation rules.

Public-interest environmental remedies require separate consideration.

Application to autonomous space infrastructure:

Construction of satellite ground stations, tracking facilities, and launch infrastructure may affect neighbouring communities.

This decision supports consideration of community interests, livelihood protection, and environmental restoration when approving infrastructure projects.

Case 6. Constitutional Court Decision Concerning High-Voltage Electricity Transmission Infrastructure

Reference: Constitutional Court ruling concerning the Electricity Generating Authority of Thailand Act B.E. 2511 (1968), discussed in the Constitutional Court's 2011 annual ruling summaries.

Background:

The dispute concerned statutory provisions relating to the installation of high-voltage electricity transmission lines.

The legal concerns included environmental surveys, notification of nearby residents, public participation, expropriation procedures, and compensation.

Decision:

The Constitutional Court considered whether the statutory provisions adequately protected constitutional rights concerning environmental conditions, public participation, and compensation.

The relevant statutory provisions were found inconsistent with constitutional protections under the 2007 Constitution.

constitutionalcourt.or.th

Legal principles:

Infrastructure development must respect constitutional rights.

Affected people should receive appropriate information.

Public participation is relevant to infrastructure decisions.

Expropriation and compensation require legal safeguards.

Technological infrastructure cannot automatically override individual rights.

Application to autonomous space infrastructure:

This decision is relevant to the construction of:

Satellite communication towers.

Tracking and monitoring facilities.

Launch infrastructure.

Ground-based satellite communication networks.

Large-scale space technology installations.

It supports a rights-based approach to infrastructure governance.

6. Comparative Analysis of the Six Decisions

These decisions should not be interpreted as establishing a complete Thai space-liability doctrine. They provide existing legal principles that can be adapted to future space infrastructure disputes.

7. Autonomous Space Infrastructure and Contractual Governance

Space infrastructure frequently involves multiple parties operating under complex commercial agreements.

For example, a Thai satellite operator may enter into contracts with:

Satellite manufacturers.

AI software developers.

Launch service providers.

Insurance companies.

Ground-station operators.

International telecommunications companies.

Data processing providers.

A comprehensive contract should address the following issues.

1. Ownership provisions

Contracts must identify ownership of satellites, software, equipment, and related intellectual property.

2. Operational control

They should specify who has authority to control autonomous satellite operations and emergency manoeuvres.

3. Maintenance obligations

The parties should establish responsibility for software updates, equipment maintenance, and system monitoring.

4. Service interruption

Contracts should address compensation for satellite failure, communication interruptions, and operational downtime.

5. Cybersecurity

Operators should establish security standards, incident reporting procedures, and recovery obligations.

6. Insurance

Contracts should specify appropriate insurance coverage for launch failures, satellite collisions, equipment damage, and third-party claims.

7. Dispute resolution

Commercial agreements should specify whether disputes will be resolved through Thai courts, arbitration, or another agreed dispute-resolution mechanism.

8. Autonomous Space Infrastructure and Property Rights

Property rights become particularly complicated when physical assets operate beyond national territory.

Thai law can govern ownership of satellites, equipment, and terrestrial infrastructure through appropriate domestic legal principles.

However, three distinctions are important.

First: Satellite ownership

A company may own a satellite without owning the orbital space occupied by it.

Second: Ground infrastructure ownership

Land, buildings, antennas, and control equipment located in Thailand may be subject to ordinary Thai property and land laws.

Third: Orbital coordination

Orbital positions and radiofrequency arrangements involve international coordination and regulatory rights rather than ordinary private ownership of space.

The Outer Space Treaty prohibits national appropriation of outer space through sovereignty, occupation, or other means.

Therefore, Thailand's domestic property law cannot create territorial ownership of an orbital position.

9. Autonomous Space Infrastructure and Consumer Protection

Satellite infrastructure is increasingly used to provide essential services.

Examples include:

Satellite internet.

Remote telecommunications.

Navigation services.

Agricultural monitoring.

Weather information.

Emergency communication.

Disaster prediction.

Where an autonomous satellite system fails, consumers and businesses may suffer financial losses.

Potential legal claims may arise from:

Misrepresentation of service quality.

Breach of service agreements.

Negligent infrastructure maintenance.

Unfair contractual terms.

Failure to provide agreed services.

Unlawful processing or disclosure of personal data.

Thailand's Consumer Protection Act B.E. 2522 and Personal Data Protection Act B.E. 2562 may become relevant depending on the service and the nature of the violation.

10. AI Governance and Human Responsibility

One of the most difficult legal questions concerns the responsibility of autonomous systems.

Suppose an AI-controlled satellite independently decides to change its orbit, causing damage to another satellite.

Can the AI itself be sued?

Under the present Thai civil-law framework, AI does not automatically possess independent legal personality.

Responsibility must instead be examined through the conduct and legal obligations of identifiable participants.

The appropriate defendant depends on the facts, contractual arrangements, applicable statutory duties, and evidence of causation.

Recommended principle: Autonomous decision-making should never automatically eliminate the legal accountability of the organisations responsible for designing, authorising, controlling, and operating the infrastructure.

11. Major Legal Challenges in Thailand

Several important challenges require legislative attention.

A. Absence of comprehensive space legislation

The proposed Space Affairs Act has been under development for several years.

The draft legislation addresses matters such as:

Space activity licensing.

Space objects.

Space debris.

Operators.

Registration.

Government supervision.

Space-related infrastructure.

However, the legislation remains under development as of November 2026.

mgronline+2

B. Liability for autonomous decisions

Existing civil-law principles were not specifically designed for AI-controlled spacecraft.

The law requires clearer rules for allocating responsibility among operators, manufacturers, software developers, and contractors.

C. Space debris

Space debris creates risks for satellites, spacecraft, and future orbital activities.

Thailand needs appropriate rules for:

Debris prevention.

Collision avoidance.

Satellite end-of-life procedures.

Deorbiting.

Monitoring and reporting.

Financial responsibility for damage.

D. International jurisdiction

Satellite operations frequently involve several countries.

A Thai company may own a satellite manufactured abroad, launched from another country, and operated through an international ground station.

The Conflict of Laws Act B.E. 2481 and applicable international agreements become relevant to determining jurisdiction and governing law.

E. Insurance and financial compensation

Space operations involve substantial financial risks.

Thailand should develop appropriate insurance requirements and financial-security mechanisms to ensure that victims of space-related accidents can obtain compensation.

12. Proposed Autonomous Space Infrastructure Governance Model for Thailand

Thailand could develop a specialised governance model with seven interconnected pillars.

Thai Autonomous Space Governance Framework

National Space Governance Authority

National policy, licensing, supervision and coordination

Civil liability

Compensation, negligence and insurance

AI governance

Human oversight and algorithmic safety

Infrastructure security

Cybersecurity and operational resilience

Environmental protection

Debris prevention and environmental assessment

Property and contracts

Ownership, licensing and commercial rights

International cooperation

Treaties, registration and cross-border disputes

Accountable and sustainable space infrastructure

Safety • Public interest • Innovation • Legal certainty

The framework should include the following reforms.

Establish a comprehensive licensing and authorisation system for private space operators.

Introduce mandatory registration and reporting of relevant space objects.

Establish clear civil liability rules for autonomous space operations.

Require minimum third-party insurance for high-risk activities.

Establish cybersecurity and AI safety standards.

Introduce mandatory collision-avoidance and debris-mitigation procedures.

Establish accessible procedures for compensation and dispute resolution.

13. Recommendations for Thai Legislative Reform

Thailand should consider incorporating the following provisions into its proposed Space Affairs Act.

A particularly important reform would be to establish a clear relationship between the proposed Space Affairs Act and existing legislation, especially the Civil and Commercial Code, Telecommunications Business Act, Environmental Quality Promotion and Preservation Act, and Liability for Wrongful Acts of Officials Act.

14. Conclusion

Civil Law and Autonomous Space Infrastructure Governance in Thailand represents an emerging legal field at the intersection of civil liability, property rights, contract law, administrative regulation, telecommunications, environmental protection, and international space law.

The Thaicom 7 and Thaicom 8 dispute demonstrates the importance of contractual clarity and regulatory authority in satellite operations. The Maya Bay, Mae Moh, Racha Thewa, Sakom Jetty, and electricity transmission infrastructure decisions provide additional principles concerning environmental accountability, administrative supervision, causation, community interests, and constitutional protection.

The most significant challenge is that autonomous space infrastructure can make operational decisions independently, while existing civil-law systems generally assign responsibility to legally identifiable individuals and organisations.

Thailand therefore needs a comprehensive statutory framework that balances technological innovation with safety, public accountability, environmental sustainability, and effective compensation.

The central legal principle should be that technological autonomy must not become legal irresponsibility.
