From Paris to Chicago and the first sixteen Articles
The Chicago Convention is the constitutional foundation of international civil aviation. Its opening Articles begin with sovereignty, separate civil from State aircraft, and explain the permissions and restrictions that apply when an aircraft crosses a national boundary.
The historical bridge
The Paris Convention of 13 October 1919 was the first broadly international agreement on civil aviation. It created the International Commission for Air Navigation and laid early technical standards. The Chicago Convention, signed on 7 December 1944, superseded that arrangement. India ratified the Chicago Convention, which contains 96 Articles.
Articles 1 to 4, basic legal status
| Article | Subject | Operational meaning |
|---|---|---|
| 1 | Sovereignty | Every State has complete and exclusive sovereignty over the airspace above its territory. |
| 2 | Territory | Territory includes land areas and adjacent territorial waters under the sovereignty, protection or mandate of the State. |
| 3 | Civil and State aircraft | The Convention applies to civil aircraft. Military, customs and police aircraft are State aircraft. A State aircraft needs special authorisation to enter or land in another State, and States must have due regard for civil aviation safety. |
| 4 | Misuse of civil aviation | A Contracting State agrees not to use civil aviation for a purpose inconsistent with the aims of the Convention. |
Articles 5 to 16, flight over another State
| Article | Rule in plain language |
|---|---|
| 5 | A non-scheduled international flight may fly across a State and make non-traffic stops, subject to the State's right to require landing, prescribed routes or special permission. |
| 6 | A scheduled international air service requires special permission or authorisation from the State concerned. |
| 7 | A State may refuse cabotage, which is carriage for remuneration between two points within its territory by an aircraft of another State. |
| 8 | A pilotless aircraft may not fly over another State without special authorisation and must be controlled to avoid danger to civil aircraft. |
| 9 | A State may establish prohibited areas for military necessity or public safety, applied without unjust discrimination. |
| 10 | A State may require arrival at and departure from a designated customs airport. |
| 11 | A State's air regulations apply equally to aircraft of all nationalities while within its territory. |
| 12 | Aircraft must comply with the applicable rules of the air. Over the high seas, the rules established under the Convention apply. |
| 13 | Entry, clearance, immigration, passport, customs and quarantine laws must be followed on entry, departure and while in the territory. |
| 14 | States take effective measures to prevent spread of communicable disease by air navigation. |
| 15 | Public airports and air navigation services are available without nationality discrimination, and charges on foreign aircraft must not exceed those on national aircraft for comparable use. |
| 16 | Authorities may search another Contracting State's aircraft on landing or departure and inspect Convention documents without unreasonable delay. |
Nationality, facilitation, documents and international standards
Articles 17 to 42 connect the aircraft to its State, reduce border delays, require essential documents, establish mutual recognition and create the process by which international standards and national differences coexist.
Articles 17 to 28
| Article | Subject and effect |
|---|---|
| 17 | An aircraft has the nationality of the State in which it is registered. |
| 18 | An aircraft cannot be validly registered in more than one State at the same time, though registration may be transferred. |
| 19 | Registration and transfer follow the national law of the registering State. |
| 20 | Aircraft in international air navigation display nationality and registration marks. |
| 21 | The registering State supplies ICAO with information concerning ownership and control of registered aircraft. |
| 22 | States adopt practicable measures to facilitate and expedite international navigation and prevent unnecessary delay. |
| 23 | Customs and immigration procedures should conform, as practicable, with practices established or recommended under the Convention. |
| 24 | Aircraft, fuel, oil, spare parts, regular equipment and aircraft stores admitted temporarily receive the stated customs-duty treatment. |
| 25 | A State undertakes to provide practicable assistance to aircraft in distress within its territory. |
| 26 | The State of Occurrence institutes an accident inquiry in the defined circumstances and permits the State of Registry to appoint observers. |
| 27 | An aircraft on a flight cannot be seized merely for violation of patent laws under the Convention conditions. |
| 28 | States provide airports, radio, meteorological and other air navigation facilities and adopt standard systems as practicable. |

| 39 | A certificate or licence not meeting the international requirements carries an endorsement giving full particulars. |
| 40 | An endorsed aircraft certificate or personnel licence cannot be used in international navigation without permission of the State or States entered. |
| 41 | The stated airworthiness provisions do not apply retrospectively to certain aircraft or equipment whose prototypes were submitted before the specified three-year point. |
| 42 | The stated personnel standards do not apply retrospectively to certain licences issued before the specified one-year point, but apply to personnel whose licences remain valid five years after adoption of the standard. |
ICAO objectives, organisation and regional structure
ICAO is the permanent organisation created by the Chicago Convention. It is a specialised agency linked with the United Nations, but its Assembly, Council, commissions and Secretariat have distinct functions.
Status and objectives
ICAO became a specialised United Nations agency in 1947. Its headquarters is in Montreal, Canada. Bali lists 193 members, including the Cook Islands. Its aims are to develop principles and techniques of international air navigation and foster planning and development of international air transport.
- Ensure safe and orderly growth of international civil aviation.
- Encourage aircraft design and operation for peaceful purposes.
- Encourage development of airways, airports and air navigation facilities.
- Meet the need for safe, regular, efficient and economical air transport.
- Prevent economic waste caused by unreasonable competition.
- Ensure that Contracting State rights are respected and each has a fair opportunity to operate international airlines.

The five freedoms of the air
A freedom of the air is a traffic privilege between States. The first two are technical freedoms. The next three are commercial freedoms and describe where passengers, mail or cargo are put down or taken on.
The two agreements
| Agreement | Privileges | India in Bali |
|---|---|---|
| International Air Services Transit Agreement, 1944 | First and second freedoms for scheduled international services. | Ratified by India. |
| International Air Transport Agreement, 1944 | First and second freedoms plus the third, fourth and fifth commercial freedoms. | Not ratified by India. |
Freedom by freedom
| Freedom | Privilege | Memory cue |
|---|---|---|
| First | Fly across another participating State without landing. | Overfly. |
| Second | Land in another participating State for non-traffic purposes, such as refuelling or repair. | Technical stop. |
| Third | Put down traffic in another State that was taken on in the aircraft's State. | Carry out from home. |
| Fourth | Take on traffic in another State for carriage to the aircraft's State. | Carry home. |
| Fifth | Carry traffic between two foreign States on a service connected with the aircraft's State. | Foreign to foreign, linked to home service. |
Cabotage is separate
Cabotage is carriage of passengers, mail or cargo between two points in the same country by an aircraft of another State. Article 7 permits a State to refuse it. Do not confuse cabotage with the fifth freedom, which concerns traffic between different foreign States on a service linked to the airline's home State.
Conventions addressing unlawful acts
The security conventions form a chain. Tokyo addresses offences and authority on board, The Hague targets unlawful seizure, Montreal targets acts against aviation safety, later instruments extend coverage to airports, explosives and modern threats.
Tokyo Convention 1963
The Tokyo Convention applies to offences against penal law and to acts that jeopardise aircraft safety, persons, property, good order or discipline on board. It generally applies to acts on an aircraft registered in a Contracting State while in flight, over the high seas or outside any State's territory, and excludes military, customs and police aircraft.
The State of Registry is competent to exercise jurisdiction. Another State may intervene in the stated cases, including effects in its territory, an offence by or against its national or permanent resident, an offence against its security, breach of its flight rules, or action needed to meet a multilateral obligation.
Aircraft commander powers
- Impose reasonable restraint where there are reasonable grounds to believe that a person has committed or is about to commit a covered offence or act.
- Act to protect the aircraft, persons or property, maintain good order and discipline, or enable delivery or disembarkation of the person.
- Require or authorise crew assistance. The commander may request or authorise passenger assistance, but cannot require it.
- Notify the authorities as soon as practicable, preferably before landing, when a restrained person is on board and state the reasons.
For the general scope, the aircraft is considered in flight from application of power for take-off until the landing run ends. For commander powers, the relevant period begins when all external doors close after embarkation and ends when a door opens for disembarkation, with special continuation after a forced landing until competent authorities take over.
The security treaty chain
| Instrument | Main subject |
|---|---|
| The Hague Convention 1970 | Suppression of unlawful seizure of aircraft, with severe punishment and extradition or prosecution obligations. |
| Montreal Convention 1971 | Suppression of violence on board, destruction or dangerous damage to an aircraft in service, placement of destructive devices, damage to navigation facilities, interference with communications and knowingly false information endangering a flight. |
| Montreal Protocol 1988 | Extends protection to airports serving international civil aviation, including serious violence, damage to facilities or aircraft not in service, and disruption of airport services. |
| Montreal Convention 1991 | Marking of plastic explosives for detection. |
| Beijing Convention 2010 | Updates security law for use of civil aircraft as a weapon, biological, chemical or nuclear weapons and substances, cyber attacks on navigation or safety systems, and organisation or contribution to offences. Bali states that India had not signed and ratified it. |
Carrier liability, surface damage and aircraft finance
A separate treaty chain deals with private rights rather than operational safety. It covers contracts and carrier liability, third-party damage on the surface, and legal interests in financed aircraft.
Warsaw to Montreal 1999
| Instrument | Purpose |
|---|---|
| Warsaw Convention 1929 | Unifies rules for international carriage of passengers, baggage and cargo, including documentation, carrier liability and jurisdiction. |
| Hague Protocol 1955 | Amends the Warsaw system. |
| Guadalajara Convention 1961 | Extends the system to carriage performed by a person other than the contracting carrier. |
| Guatemala City Protocol 1971 and Montreal Protocols 1975 | Further attempted amendments to the Warsaw system. |
| Montreal Convention 1999 | Creates a modern unified liability system intended to replace the fragmented Warsaw chain. |
| Carriage by Air Act 1972, amended in 2009 | Provides the Indian statutory framework for the rights and liabilities of air carriers. |
Transport documents and liability
Bali notes that the Warsaw system became one of the most widely accepted private-law unifications, with 152 States described as parties in the printed text. A passenger ticket identifies the place and date of issue, departure and destination, agreed stopping places, carrier identity and the applicability of liability rules. Loss or irregularity of the ticket does not itself invalidate the contract of carriage. Checked baggage other than small personal items is covered by a baggage check, with copies for passenger and carrier.
Bali retains a historical 100,000 Special Drawing Rights figure while explaining the earlier liability system, then gives the Montreal 1999 two-tier passenger liability value. Up to 113,100 Special Drawing Rights for injury or death, the carrier cannot defeat the claim by proving absence of negligence. Above that level, the carrier may defend itself by proving that it was not negligent or otherwise at fault. These figures are studied here as Bali's printed examination values.
Ground damage and property interests
| Instrument | Subject | India in Bali |
|---|---|---|
| Rome Convention 1952 | Liability for damage caused by foreign aircraft to persons or property on the surface, with liability related to aircraft weight and compulsory insurance concepts. | Bali states that India had not ratified it. |
| Montreal Protocol 1978 | Amends the Rome Convention and extends its treatment to an operator located in another Contracting State. | Read with the Rome system. |
| Geneva Convention 1948 | International recognition of rights in aircraft bought through hire purchase, lease or mortgage. | Protects recognised property interests. |
| Cape Town Convention and Protocol 2001 | International interests in mobile equipment applied to aircraft objects, with a prompt and legally certain enforcement system supporting aircraft finance. | Bali states that India ratified the Convention and Protocol in 2008. |
Denunciation or withdrawal
A State Party withdraws by written notification to the depositary, which is ICAO for the instruments listed by Bali. Tokyo 1963, The Hague 1970, Montreal 1971, Montreal Protocol 1988 and Beijing 2010 use a six-month notice period. Montreal 1999 uses 90 days.
Indian organisations in the international system
International commitments require national institutions. Bali places the Ministry of Civil Aviation above the aviation bodies, identifies DGCA as the safety regulator and describes AAI as the principal airport and air navigation service organisation within its assigned jurisdiction.
Ministry of Civil Aviation
The Ministry formulates national policy and programmes for development and regulation of civil aviation. It administers national aviation legislation and exercises administrative control over attached and autonomous organisations and public-sector aviation bodies.
DGCA functions listed by Bali
- Register civil aircraft.
- Formulate airworthiness standards and grant certificates of airworthiness.
- License pilots, aircraft maintenance engineers and flight engineers, and conduct the required examinations and checks.
- License air traffic controllers.
- Certify aerodromes and communication, navigation and surveillance facilities.
- Grant Air Operator Certificates and regulate Indian and foreign air transport services operating to, from, within and over India, including required clearances.
- Carry out the safety-regulatory and accident-prevention functions stated in Bali, while formal independent accident investigation is handled under the current Indian investigation framework.
- Process amendments to aviation legislation, Civil Aviation Requirements, Aeronautical Information Circulars and related material, and initiate proposals needed to give effect to international conventions.
- Coordinate flexible use of airspace by civil and military agencies and interact with ICAO on additional routes through Indian airspace.
- Monitor aircraft noise and engine emissions with reference to Annex 16 and coordinate with environmental authorities.
- Promote indigenous aircraft design and manufacture by acting as a catalyst.
- Approve dangerous-goods training programmes and issue relevant carriage authorisations.
Airports Authority of India
AAI was formed on 1 April 1995 by merging the International Airports Authority of India and National Airports Authority. Bali lists the following principal functions.
- Design, develop, operate and maintain international and domestic airports and civil enclaves.
- Control and manage assigned Indian airspace, including accepted responsibilities beyond territorial limits.
- Construct, modify and manage passenger terminals.
