BACKGROUND
5 For a number of days, from around 20 September 2021, protests and demonstrations occurred in Melbourne. The applicants had been reporting on those protests and demonstrations. The applicants' reporting included the use of a helicopter for the purposes of taking aerial footage and using that footage for reporting, including by way of live broadcasting.
6 CASA was established by s 8 of the Civil Aviation Act 1988 (Cth). By s 9 of that Act, among other things, CASA has the function of 'conducting the safety regulation' of civil air operations in Australian territory. Separately, the Airspace Act 2007 (Cth) has the effect of conferring certain functions upon CASA. Section 11(1) of the Airspace Act provides that regulations may make provision for and in relation to conferring functions and powers on CASA that are in connection with the administration and regulation of Australian-administered airspace. The Airspace Regulations were made under the Airspace Act. Regulation 6, which was the key provision in this proceeding, empowers CASA to declare that an area is a 'restricted area' in certain circumstances. As its description makes apparent, aircraft are restricted by such a declaration from flying in a 'restricted area'. Regulation 6 of the Airspace Regulations relevantly provides as follows:
6 Designation of prohibited, restricted or danger areas
(1) CASA may, in writing, make a declaration designating an area of Australian territory to be a prohibited area, a restricted area or a danger area.
…
(3) CASA must not declare an area to be a restricted area unless, in the opinion of CASA, it is necessary to restrict the flight of aircraft over the area to aircraft flown in accordance with specified conditions in the interests of any of the following:
(a) public safety, including the safety of aircraft in flight;
(b) the protection of the environment;
(c) security.
…
(5) A declaration:
(a) must specify an area by reference to its boundaries; and
(b) may specify the boundaries of an area to extend to a volume of airspace.
(6) A declaration made under this regulation does not take effect until published in accordance with regulation 7.
(7) Unless sooner revoked, a declaration ceases to have effect:
(a) on the day, or on the day and time, specified in the declaration; or
(b) on the day, or on the day and time, of the occurrence of an event specified in the declaration; or
(c) in the circumstances specified in the declaration.
Note: A declaration made under this regulation is not a legislative instrument (see paragraph (a) of item 1A of Part 2 of Schedule 1 to the Legislative Instruments Regulations 2004).
7 Relevantly, under reg 6(3)(a) of the Airspace Regulations, CASA may only declare an area to be a restricted area if in its opinion, it is necessary 'to restrict the flight of aircraft over the area to aircraft flown in accordance with specified conditions', in the interests of public safety. Regulation 7 provides that CASA must cause such a declaration to be published, in the case of a declaration to have effect for less than three months, in a 'Notice to Airmen' (NOTAM) as defined in the Air Services Regulations 2019 (Cth). The NOTAM is published in accordance with reg 15 of the Air Services Regulations.
8 On the afternoon of 22 September 2021, a NOTAM was published in the following terms:
MELBOURNE FIR (YMMM)
C1019/21 REVIEW C1018/21
TEMPO RESTRICTED AREA ACT

9 The NOTAM identified that the purpose of the declaration was 'public safety'. The NOTAM provided that there was to be no entry to that airspace without the approval of the 'controlling authority', being Victoria Police. The NOTAM provided the contact phone number of a senior police officer within Victoria Police. There is no reference in the statutory scheme to the concept of a 'controlling authority'.
10 Later in the afternoon on 22 September 2021, a further NOTAM was notified, in the following terms:
MELBOURNE FIR (YMMM)
C1021/21 REVIEW C1020/21

DAILY 2000/0900
11 This second NOTAM was in generally the same terms, and had the same effect, as the first NOTAM, except that there were now two controlling authorities identified: Airservices Australia for 'controlled airspace', and Victoria Police for 'Class G airspace'. Controlled airspace is airspace actively managed and controlled by air traffic controllers. Class G airspace is uncontrolled airspace. Nothing turns on the role of Airservices Australia; the applicants' helicopter flies in Class G airspace, and they only took issue with the designation of Victoria Police as the 'controlling authority' in Class G airspace.
12 The effect of the NOTAMs (and the decision they published) was that the applicants' helicopter, used to obtain aerial footage for news media broadcast, could not be used in the restricted area, without the approval of Victoria Police.
13 It can be seen from the penultimate line in each NOTAM that CASA's declaration was to expire at 9.00 am on Sunday 26 September 2021, four days after the NOTAMs were published.
14 After the second NOTAM was published, at about 5.51 pm on 22 September 2021, Victoria Police issued the following media release:
Earlier today Victoria Police made an application to CASA to temporarily restrict air space in the Melbourne CBD.
While this decision was made for operational and safety reasons in relation to the protest activity, we acknowledge the concerns raised by the media.
As a result, Victoria Police will include a provision for media outlets to operate their aircrafts over the CBD.
As part of the conditions, pilots will need to obtain approval from Victoria Police airwing before taking off to ensure there are no safety risks.
Media outlets will also be required to delay publishing any livestream footage from the air by 60 minutes or at the conclusion of the operation.
This is because protestors were actively monitoring aerial livestreams, compromising the police operation and putting the safety of members at risk.
(Emphasis added.)
15 The applicants note that the 'provision' and requirements referred to in Victoria Police's media release were not reflected in either NOTAM, nor were they referred to in the decision that the NOTAMs published.
16 At about 6.00 pm on 22 September 2021, after some preliminary conversations with the Court, the applicants notified the Associate to the Duty Judge, Rofe J, that they sought to have the matter listed the next morning. At 9.30 pm that evening, and in correspondence that followed, the applicants notified CASA that they were seeking urgent judicial review of its decision. The Court listed the matter for an urgent hearing at 9.00 am the next morning, 23 September 2021.
17 The applicants prepared an application overnight and filed and served it, together with a short supporting affidavit, shortly before the hearing commenced at 9.00 am. At the time the application was filed, the applicants did not have access to the actual decision that had been notified in the NOTAMs. Indeed, they did not know whether there had been one or two decisions made by CASA. However, it now appears from an affidavit filed on behalf of CASA that there was only one decision, reflected in the second NOTAM. Again, nothing turns on this, but it explains why the application and reasons for the interlocutory judgment by Rofe J each refer to two decisions.
18 In their application, the applicants invoked the Court's jurisdiction under the Administrative Decisions (Judicial Review) Act 1977 (Cth) (ADJR Act), and sought judicial review of CASA's decisions. They sought orders:
(a) quashing the decisions by CASA purportedly made on 22 September 2021 to declare the area within a three nautical miles radius of coordinates 374900S 1445800E to be a restricted area; and
(b) declaring that the decisions were of no force or effect.
19 The grounds for their application were set out in the originating application. In brief, the applicants alleged under s 5(1) of the ADJR Act that:
(a) CASA did not have jurisdiction to make the decisions that it did, in that it had not complied with reg 6 of the Airspace Regulations;
(b) CASA's purported decisions were an improper exercise of power. This was put on two bases. One basis was that CASA acted at the behest or direction of Victoria Police. The other was legal unreasonableness;
(c) CASA had impermissibly delegated its power to Victoria Police and did not give independent attention to the discretion which is conferred upon it;
(d) a breach of the rules of natural justice occurred in connection with the decision;
(e) there was no evidence to justify the making of the decision; and
(f) the decision was otherwise contrary to law.
20 The applicants sought urgent interlocutory relief to suspend and/or stay the operation of the decisions until the hearing and determination of the proceeding.
21 At the hearing on 23 September 2021, senior counsel for the applicants made submissions in support of their application for interlocutory relief. Senior counsel for CASA appeared, and requested until 4.30 pm that day for his client to put on evidence. He also made some brief submissions. The hearing was adjourned until 12.00 pm at which time Rofe J delivered judgment on the interlocutory application: Nine Network Australia Pty Ltd v Civil Aviation Safety Authority [2021] FCA 1160 (Nine Network v CASA). Her Honour found that (at [6]):
For the reasons articulated in [senior counsel's] submissions this morning, I consider that there is a serious question to be tried on the application. I consider that on the material presently before the court, the balance of convenience lies with the stay of the Decisions until a substantive hearing of the application can take place.
22 Her Honour granted the stay until further order and indicated that a substantive hearing could be accommodated the following week. Since that time, I have granted at the joint request of the parties who were in negotiation, adjournments of the substantive hearing.
23 The applicants say that while the relief granted by Rofe J was interlocutory, the effect of her Honour's decision was to grant the applicants final relief. That is because the decision sought to be challenged would expire on Sunday 26 September 2021, and therefore the stay would cover the entire period in which the decision was in effect.
24 Very shortly after her Honour's orders were made, on the same day, CASA revoked the decision.
