CASA 43/25 — Interception of Civil Aircraft (CASA 73/17) Amendment Instrument 2025

Purpose

This instrument amends instrument CASA 73/17 — Civil Aircraft in Australian Territory (Interception) Direction 2017 (CASA 73/17), which would otherwise expire at the end of 31 July 2025, to continue its operation in relation to foreign registered aircraft. The purpose of the amendment is to continue to enable the enforcement of procedural requirements established by international agreement to be followed by the pilot in command of a foreign registered aircraft operating in Australian territory under a foreign air transport Air Operator’s Certificate (AOC) or New Zealand AOC with Australia New Zealand Aviation (ANZA) privileges, in the event of an aircraft interception by the Australian Defence Force or Australian Federal Police acting under the authority of the Commonwealth.

 

Legislation

Section 98 of the Civil Aviation Act 1988 (the Act) empowers the Governor-General to make regulations for the Act and in the interests of the safety of air navigation. Relevantly, the Governor-General has made the Civil Aviation Safety Regulations 1998 (CASR).

 

Section 3A of the Air Navigation Act 1920 provides for the approval of ratification of the Convention on International Civil Aviation (the Chicago Convention) of 1944.

 

Section 22 of the Act provides for the interception of an aircraft registered in Australia or operated by an Australian operator that is in flight over the territory of a foreign country.

 

Subpart 11.G of CASR provides for the Civil Aviation Safety Authority (CASA) to issue directions in relation to matters affecting the safety of air navigation. Under paragraph 11.245(1)(a) of CASR, CASA may, by instrument, issue a direction about any matter affecting the safe navigation and operation of aircraft. Subregulation 11.245(2) of CASR provides that CASA may issue such a direction only if CASA is satisfied that it is necessary to do so in the interests of the safety of air navigation, only if the direction is not inconsistent with the Act, and only for the purposes of CASA’s functions.

 

Under paragraph 11.250(a) of CASR, a direction under regulation 11.245 ceases to be in force on the day specified in the direction. Under regulation 11.255, it is an offence of strict liability (with a maximum penalty of 50 penalty units) to contravene a direction under regulation 11.245.

 

Regulation 91.695 of CASR makes it an offence if an aircraft is intercepted by another aircraft and the pilot in command does not comply with requirements prescribed in the Part 91 Manual of Standards. Section 23.02 of the Part 91 Manual of Standards prescribes, for that purpose, interception procedures set out in Annex 2 of the Chicago Convention. Under regulation 91.020, regulation 91.965 does not apply in relation to:

(a) a foreign registered aircraft that is operated in Australian territory under a foreign air transport AOC; or

(b) a foreign registered aircraft that is operated in Australian territory under a New Zealand AOC with ANZA privileges that is in force for Australia.

 

The Acts Interpretation Act 1901 (the AIA)

Under subsection 33(3) of the AIA, where an Act confers a power to make, grant or issue any instrument of a legislative or administrative character (including rules, regulations or bylaws), the power shall be construed as including a power exercisable in the like manner and subject to the like conditions (if any) to repeal, rescind, revoke, amend, or vary any such instrument. Under subsection 13(1) of the LA, subsection 33(3) of the AIA applies to legislative instruments as if each provision of the instrument were a section of an Act.

 

Background

CASA 33/22 — Interception of Civil Aircraft (CASA 73/17) Amendment Instrument 2022 (CASA 33/22) extended the duration of CASA 73/17 from 31 July 2022 to 31 July 2025. Also, CASA 33/22 made some other amendments of CASA 73/17. Those other amendments are described in the Explanatory Statement for CASA 33/22, under the headings “Overview of instrument” and “Content of instrument”.

 

Overview of instrument

The instrument extends by a period of 3 years the duration of CASA 73/17. The instrument also includes a note immediately below paragraph 1(b) specifying that, for regulation 11.250 of CASR, the directions in section 4 continue to be in force until the repeal of CASA 73/17.

 

The Explanatory Statement for CASA 33/22 includes the following assessment by CASA of the impact of that instrument on aviation safety:

CASA considers that the amended instrument mitigates against any adverse risks to the safety of air navigation by ensuring that interception aircraft follow globally recognised procedures and limitations.

 

Because the only amendment that the instrument makes to CASA 73/17 extends its duration and includes the note below paragraph 1(b), CASA considers that the assessment mentioned in the preceding paragraph continues to apply.

 

Documents incorporated by reference

The instrument doesn’t include a provision that incorporates any documents by reference.

 

Content of instrument

Section 1 names the instrument.

 

Section 2 mentions when the instrument commences.

 

Section 3 mentions that Schedule 1 amends CASA 73/17.

 

Schedule 1  Amendment

Item [1] substitutes paragraph 1(b) of CASA 73/17. Substituted paragraph 1(b):

(a) extends the duration of CASA 73/17 to 31 July 2028; and

(b) includes a note below paragraph 1(b) specifying, for regulation 11.250 of CASR, the intended duration of the directions in section 4.

Legislation Act 2003 (the LA)

Paragraph 10(1)(d) of the LA provides that an instrument will be a legislative instrument if it includes a provision that amends or repeals another legislative instrument. The instrument amends CASA 73/17 that was registered as a legislative instrument. Therefore, the instrument is also a legislative instrument, subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LA.

 

Sunsetting

Part 4 of Chapter 3 of the LA (the sunsetting provisions) does not apply to the instrument, because the instrument relates to aviation safety and is made under CASR (see item 15 of the table in section 12 of the Legislation (Exemptions and Other Matters) Regulation 2015).

 

In this case, the instrument amends CASA 73/17 and is almost immediately spent and repealed in accordance with the automatic repeal provisions in section 48A of the LA. CASA 73/17 is itself repealed at the end of 31 July 2028 by virtue of the terms of paragraph 1(b) of CASA 73/17 (as amended by the instrument). Therefore, in practice, no sunsetting avoidance issues arise and there is no impact on parliamentary oversight.

 

Consultation

Consultation under section 17 of the LA has not been undertaken in this case.

 

The Explanatory Statement for CASA 33/22 includes the following information about consultation:

The instrument continues the effect of an existing instrument and ensures Australia continues to meet its international obligations under the Chicago Convention regarding the interception of civil aircraft. The instrument does not alter the Part 91 interception procedures but provides a mechanism for the enforcement of those procedures.

 

The only amendment that the instrument makes to CASA 73/17 extends its duration and includes a note below paragraph 1(b) specifying, for regulation 11.250 of CASR, the intended duration of the directions in section 4. For that reason, CASA considers that the information about consultation continues to apply. Therefore, CASA is satisfied that no further consultation is appropriate or reasonably necessary for this instrument under section 17 of the LA.

 

Sector risk, economic and cost impact

Subsection 9A(1) of the Act states that, in exercising its powers and performing its functions, CASA must regard the safety of air navigation as the most important consideration. Subsection 9A(3) of the Act states that, subject to subsection (1), in developing and promulgating aviation safety standards under paragraph 9(1)(c), CASA must:

(a) consider the economic and cost impact on individuals, businesses and the community of the standards; and

(b) take into account the differing risks associated with different industry sectors.

 

The cost impact of a standard refers to the direct cost (in the sense of price or expense) which a standard would cause individuals, businesses and the community to incur. The economic impact of a standard refers to the impact a standard would have on the production, distribution and use of wealth across the economy, at the level of the individual, relevant businesses in the aviation sector, and the community more broadly. The economic impact of a standard could also include the general financial impact of that standard on different industry sectors.

 

The instrument only extends an expiring instrument (CASA 73/17) with the same provisions and includes a note below paragraph 1(b) specifying, for regulation 11.250 of CASR, the intended duration of the directions in section 4. Therefore, there will be no change of economic or cost impact on individuals, businesses or the community.

 

Impact on categories of operations

The instrument only extends an expiring instrument (CASA 73/17) with the same provisions and includes a note below paragraph 1(b) specifying, for regulation 11.250 of CASR, the intended duration of the directions in section 4. Therefore, there will be no change of impact on categories of operations.

 

However, CASA has assessed that if a foreign registered aircraft conducting an operation of a kind mentioned in regulation 91.020 of CASR were intercepted and escorted to a different landing destination, it could result in economic (direct cost) impacts on the operator of the aircraft, or the persons on board the aircraft due to:

(a) increased fuel to the alternative destination and fuel to move the aircraft to a future departure destination, or

(b) increased costs for the persons on board the aircraft to get to their originally intended destination.

 

However, CASA has assessed that – if incurred – those costs would be a reasonable consequence in the context of the national security concerns that would underpin that kind of interception and escorting of a foreign registered aircraft by an Australian authority.

 

Impact on regional and remote communities

The Explanatory Statement for CASA EX33/22 includes the following information about the impact on regional and remote communities:

CASA assesses that the direction to foreign registered aircraft to comply with interception procedures when operating in Australian territory would not have any negative consequences for regional or rural areas. The normal landing destinations of such aircraft are aerodromes in capital cities. If a significant national security event did necessitate the widespread interception and escort of such aircraft to alternative landing destinations, some of these destinations are likely to be in regional or rural areas (due to the relative scarcity of capital city major aerodromes). This could result in limited but positive economic benefits to the regional or rural area.

 

The only amendment that the instrument makes to CASA 73/17 extends its duration and includes a note below paragraph 1(b) specifying, for regulation 11.250 of CASR, the intended duration of the directions in section 4. Therefore, CASA considers that the assessment mentioned in the preceding paragraph continues to apply.

 

Office of Impact Analysis (OIA)

An Impact Analysis (IA) is not required in this case, as the instrument is covered by a standing agreement between CASA and OIA under which an IA is not required for directions (OIA reference number: OIA23-06252).

 

Statement of Compatibility with Human Rights

The Statement of Compatibility with Human Rights at Attachment 1 has been prepared in accordance with Part 3 of the Human Rights (Parliamentary Scrutiny) Act 2011.

 

Making and commencement

The instrument has been made by a delegate of CASA relying on the power of delegation under subregulation 11.260(1) of CASR.

 

The instrument commences at the time that it is registered, and is automatically repealed in accordance with section 48A of the LA.

Civil Aviation Safety Authority

Overview

The Civil Aviation Safety Regulations 1998 (CASR) Amendment Instrument 2025, titled "Interception of Civil Aircraft (CASA 73/17) Amendment Instrument 2025", was enacted to extend the duration of CASA 73/17, which pertains to the interception of civil aircraft in Australian territory. The instrument was introduced to ensure that the enforcement of international procedural requirements for aircraft interceptions remains in effect, specifically concerning foreign-registered aircraft operating under foreign or New Zealand AOCs with ANZA privileges. The purpose of this amendment is to uphold the enforcement of procedures established by international agreements, ensuring safety and compliance during interceptions conducted by the Australian Defence Force or Australian Federal Police. The instrument was enacted by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Act 1988, which empowers CASA to make regulations for the safety of air navigation. The policy objective of this amendment is to maintain compliance with international obligations under the Chicago Convention and to ensure the safety of air navigation. The instrument extends the duration of CASA 73/17 from 31 July 2025 to 31 July 2028 and includes a note specifying that the directions in section 4 will remain in force until the repeal of CASA 73/17. This amendment does not alter the existing interception procedures but ensures that the enforcement mechanism remains active, thereby mitigating any potential adverse risks to aviation safety. The instrument was made under the authority delegated to CASA and is automatically repealed in accordance with the Legislation Act 2003.

Scope and Application

The Civil Aviation Safety Regulations 1998 (CASR) establish the framework for ensuring the safety of air navigation in Australia, with the Civil Aviation Safety Authority (CASA) empowered to issue directions under Subpart 11.G of CASR to enforce these safety standards. The CASA 43/25 — Interception of Civil Aircraft (CASA 73/17) Amendment Instrument 2025 amends CASA 73/17, which otherwise would expire on 31 July 2025, to continue its operation for foreign registered aircraft. The amendment is necessary to ensure the enforcement of international procedural requirements that must be followed by the pilot in command of foreign registered aircraft operating in Australian territory under a foreign air transport Air Operator’s Certificate (AOC) or a New Zealand AOC with Australia New Zealand Aviation (ANZA) privileges, in the event of an interception by the Australian Defence Force or Australian Federal Police acting under the authority of the Commonwealth. The amendment extends the duration of CASA 73/17 until 31 July 2028 and includes a note specifying that the directions in section 4 continue to be in force until the repeal of CASA 73/17. The instrument does not alter the existing interception procedures but ensures the enforcement of these procedures, which are set out in Annex 2 of the Chicago Convention. This amendment does not apply to aircraft registered in Australia or operated by Australian operators. The instrument is made under the authority of the Civil Aviation Act 1988 and the Air Navigation Act 1920, and it is subject to the Legislative Instruments Act 2003, including the requirement for tabling and disallowance in Parliament. The instrument is deemed to be a legislative instrument because it amends an existing legislative instrument, CASA 73/17. The instrument does not require consultation or an Impact Analysis as it maintains the existing regulatory framework and does not introduce new obligations or alter existing safety procedures.

Key Provisions

The primary operative sections of the CASA 43/25 — Interception of Civil Aircraft (CASA 73/17) Amendment Instrument 2025 focus on extending the duration of CASA 73/17 and ensuring that foreign registered aircraft comply with international interception procedures when operating within Australian territory. Section 1 of the instrument names it, while Section 2 details its commencement. The key amendment is in Schedule 1, Item [1], which substitutes paragraph 1(b) of CASA 73/17, extending its duration to 31 July 2028 and including a note specifying the intended duration of the directions in section 4. This amendment ensures that the procedural requirements for intercepting foreign aircraft remain in effect until the repeal of CASA 73/17. The obligations imposed by the Act on the parties it governs primarily revolve around compliance with international interception procedures. Foreign registered aircraft operating in Australian territory must follow the interception procedures set out in Annex 2 of the Chicago Convention if intercepted by the Australian Defence Force or Australian Federal Police. The pilot in command of these aircraft is required to comply with the prescribed interception procedures to maintain the safety of air navigation. There are specific offences and penalties outlined in the Civil Aviation Safety Regulations 1998 (CASR) for non-compliance with these procedures. Regulation 91.695 of CASR makes it an offence if an aircraft is intercepted by another aircraft and the pilot in command does not comply with the requirements prescribed in the Part 91 Manual of Standards. The maximum penalty for contravening a direction under regulation 11.245 is 50 penalty units. Furthermore, under regulation 11.255, it is an offence of strict liability to contravene a direction issued under regulation 11.245. The instrument does not engage any applicable rights or freedoms, and therefore, it is compatible with human rights. The Statement of Compatibility with Human Rights confirms that the legislative instrument does not raise any human rights issues, as it does not engage with any of the rights or freedoms recognised or declared in the international instruments listed in the Human Rights (Parliamentary Scrutiny) Act 2011. The instrument has been made by a delegate of CASA under the power of delegation provided in subregulation 11.260(1) of CASR and will commence upon registration. It is automatically repealed in accordance with section 48A of the Legislation Act 2003.
