Background
5 The proceeding (NSD423/2021) was commenced on 10 May 2021. It concerns work carried out by the respondent on a Cessna Citation X aircraft, which the applicant owns.
6 On 23 November 2020, prior to commencing the proceeding, the applicant's lawyer wrote to the respondent, stating amongst other things:
1. My client understands that you are presently in possession of his aircraft and that you have been performing work on the aircraft.
2. My client has not engaged your company to perform any work on his aircraft.
3. My client has not entered into a contract with your company in respect of any matters relating to the aircraft.
4. My client understands that a former employee of Mineralogy Pty Ltd, Mr Carlo Filingeri has been giving instructions to you regarding work to be performed on the aircraft.
5. My client has not authorised Mr Filingeri to give any instructions on his behalf. Mr Filingeri is employed by Mineralogy, not Mr Palmer.
6. Mr Palmer has not authorised Mineralogy (nor Mr Filingeri) to act on his behalf in respect of work to be performed on the aircraft.
7 On 4 December 2020, the respondent's lawyers responded, stating amongst other things:
It is sufficient to point out at this stage that Mr Filingeri was authorised to act on behalf of Mineralogy and in all likelihood on instructions given by Mr Palmer. In any event, the work that has been carried out was pursuant to written agreements between PremiAir and Mineralogy and that Mr Palmer, if he is the owner of the aircraft as you contend, entrusted the aircraft to Mineralogy. The scope of the work to be undertaken was dictated by the instructions given by your clients and the circumstances including, in particular, the fact that the aircraft had not been operated for many years and had been left in the open for most of that time, and obviously was not in an airworthy condition.
Relevantly, you have referred … in your letter of 23 November 2020 to the costs that Mr Palmer will incur in having the aircraft repaired and made airworthy. The confirmation that Mr Palmer wants to have the aircraft made airworthy is consistent with the instructions given by Mr Filingeri. The work that PremiAir has undertaken is necessary to achieve that end. The suggestion that your client can have the benefit of the work carried out to make the aircraft airworthy without paying for the work is absurd.
8 In a Concise Statement filed on 10 May 2021, the applicant alleged, somewhat inconsistently with the position stated in the letter of 23 November 2020 that, in 2020, Mr Filingeri was, in fact, his agent and that Mr Filingeri had entered into contracts with the respondent to carry out work on the aircraft. The applicant alleged, however, that Mr Filingeri had entered into the contracts outside the authority and scope of the agency he had been given. The applicant alleged that the contracts were entered into on 22 June 2020, 27 July 2020, 19 October 2020, and 5 November 2020. He alleged that, between about June and November 2020, the respondent obtained possession of the aircraft in accordance with the terms of the contracts, and dismantled it. He alleged that this constituted damage. He advanced claims in trespass and conversion, detinue, and unconscionable conduct within the meaning of s 21 of the Australian Consumer Law. Amongst other relief, he claimed the estimated cost of reassembling the aircraft ($932,107.92) or, alternatively, its value if not returned ($2,000,000.00).
9 In its response to the Concise Statement, filed on 11 June 2021, the respondent alleged that the applicant had appointed Mineralogy Pty Ltd (Mineralogy) to be the operator of the aircraft. It also alleged that the applicant had appointed Mr Filingeri, who was Mineralogy's chief pilot, to enter into contracts on behalf of Mineralogy for inspections, maintenance, and repairs in respect of the aircraft, which had not been operated since about 2016, to return it to an airworthy condition.
10 Prior to the commencement of proceeding NSD423/2021, Mineralogy had, itself, commenced a proceeding against the respondent (proceeding NSD46/2021). Proceeding NSD46/2021 also concerned the work carried out on the aircraft by the respondent. In a Concise Statement filed on 21 January 2021, Mineralogy alleged that, between 10 July 2020 and 22 October 2020, the respondent had invoiced it for work carried out on the aircraft, and that it had paid amounts in respect of those invoices in the mistaken belief that it was legally obliged to do so. Mineralogy alleged that it did not own the aircraft and that it had not authorised the respondent to carry out the work. It sought repayment of the amounts it had paid in that regard.
11 On 15 October 2021, the applicant's lawyer wrote to the respondent's lawyers in respect of both proceedings, stating amongst other things:
1. On 2 August 2021, my clients discovered to you documents in the above proceedings. At that time there remained, and still remains, categories of document which are outstanding. My clients had not at that time, and still have not, certified final document lists.
2. In undertaking further investigations prior to finalising discovery, including having regard to the documents requested by your client pursuant to the outstanding categories of document, my client identified and provided to me for the first time the enclosed additional document, being an Aircraft Lease Agreement naming Clive Palmer as the lessor and Mineralogy Pty Ltd as lessee, dated 25 August 2020 (Lease). I now disclose to you the Lease.
3. The Lease is plainly relevant to both proceedings and, having now been made aware of the document, my view is that it necessarily has implications for both proceedings. The implications and next steps follow:
(a) In my and my client's view, it is now necessary that NSD 423 be discontinued. I hold my client's instructions to discontinue the proceedings and I seek your client's consent to that discontinuance. I include as an enclosure a Notice of Discontinuance for your signature. Please let me know if your client has any difficulties in consenting to the discontinuance. If there are no issues, then I will file the signed Notice of Discontinuance once received.
(b) Aspects of NSD 46 now require amendment (both as a result of the identification of the Lease itself, and also as a result of discontinuance of the related proceeding NSD423). The amendments to the concise statement in NSD 46 will necessarily have flow through effects for the defence and reply, and your client's cross-claim, and for the scope of discovery and any required lay and expert evidence. …
12 The Lease granted by the applicant conferred sole and exclusive responsibility for the operation and control of the aircraft on Mineralogy. It also imposed the following obligations (amongst others) on Mineralogy:
Lessee shall, during the Term, at its own cost and expense, maintain, inspect, service, repair, overhaul and test or cause the Aircraft to be maintained, inspected, serviced, repaired, overhauled and tested so as to keep the Aircraft in good operating condition, ordinary wear and tear excepted, and in compliance with all Applicable Law, including applicable provisions of relevant regulations and the manufacturer's recommended inspection and maintenance program for the Aircraft.
The Lessee shall maintain the Aircraft in an airworthy condition with a current and valid airworthiness certification where required from the relevant authority and maintain registration of the Aircraft where required on the relevant civil aircraft registry.
