International Agreements and Organizations — Page 39, Lesson 71

We're moving into a new area now: international agreements and organizations, specifically the legal framework that protects civil aviation from acts of unlawful interference. I want to walk you through the Montreal Convention of 1971, its 1988 Supplementary Protocol, and the security standards that came out of them. Let's start with the core offences defined by the 1971 Montreal Convention. These are the acts that the international community agreed to criminalize. The first is destroying or damaging any air navigation facility, or interfering with its correct operation. So this isn't just about the aircraft itself — it covers the ground infrastructure that guides and supports flights, like radar stations, navigation beacons, and control towers. If someone damages those, or disrupts how they work, that's an offence under this convention. The second offence is the communication of information known to be false which endangers the safety of an aeroplane in flight. That's a bomb hoax, essentially — a false threat that puts an aircraft at risk. The key phrase is "known to be false." The person making the communication must know it's untrue. And the information must endanger the safety of an aeroplane in flight. So a prank call that causes a diversion or an emergency response falls squarely within this. Now, the 1971 Convention dealt with offences on board aircraft and against aircraft in flight. But there was a gap: what about violence at airports? That's where the Protocol Supplementary to the Montreal Convention of 1971 comes in. This protocol was adopted by a conference that met at Montreal in 1988. Its purpose is to extend the definition of offence given in the 1971 Convention to include specified acts of violence at airports serving international civil aviation. Let me be precise about what those acts are. The first is the intentional and unlawful use of any device, substance or weapon in performing an act of violence against a person at an airport serving international civil aviation, which causes or is likely to cause serious injury or death. So we have three elements: it's intentional, it's unlawful, and it involves a device, substance, or weapon. The act of violence is against a person, and it must cause or be likely to cause serious injury or death. The second category is the intentional and unlawful use of any device, substance or weapon to do three things. First, to destroy or seriously damage the facilities of an airport. Second, to destroy or seriously damage aircraft not in service at the airport. Note that phrase — "not in service" — because the 1971 Convention already covered aircraft in service. This protocol fills the gap for parked or grounded aircraft. And third, to disrupt the services at an airport. So even if no one is physically hurt and nothing is destroyed, if you disrupt airport operations — say, by forcing a shutdown or an evacuation — that's an offence. Now, enforcement. Contracting States — that is, the countries that have signed up to these instruments — have undertaken to make these offences punishable by severe penalties. So it's not enough to just declare these acts illegal; the penalties must be severe. The protocol also contains provisions on jurisdiction. That means it sets out which states have the legal authority to prosecute these offences — for example, the state where the offence occurred, or the state of nationality of the offender. Now, how does this all connect to ICAO? The measures taken by ICAO have resulted in the adoption of Standards and Recommended Practices — SARPs — detailed in Annex 17, which is titled "Security." The provisions of these SARPs are applicable to all Contracting States. So this is binding on every state that's a member of ICAO, not just the ones that signed the Montreal instruments. Annex 17 requires all Contracting States to do four things. First, establish national civil aviation security programmes. So each state must have its own documented plan for securing its civil aviation. Second, designate an authority responsible for security. There has to be a specific body or agency that owns this responsibility. Third, keep the level of threat under constant review. This is a continuous process — threat levels aren't static, they change, and the state must monitor them. And fourth, co-ordinate activities with other relevant national agencies and liaise with the corresponding authority in other States. So security isn't a silo — the aviation authority must work with police, customs, immigration, and other agencies domestically, and with the equivalent authorities in other countries internationally. That brings us to the final heading in this passage: Programmes and Plans. And that's where the text cuts off. But you can see the direction — the SARPs in Annex 17 are implemented through national programmes and plans, which is exactly what the first requirement I just mentioned refers to. Let me just recap the thread so it's clear in your mind. The 1971 Montreal Convention criminalizes attacks on air navigation facilities and false information endangering aircraft in flight. The 1988 Protocol extends that to violence at international airports, including against persons, against facilities, against aircraft not in service, and disruption of airport services. States must impose severe penalties and the protocol sets out jurisdiction. And ICAO has translated all of this into binding SARPs in Annex 17, which require every Contracting State to have a national security programme, a designated authority, constant threat review, and coordination with other agencies and states. That's the legal skeleton of international aviation security.
