Legal Principles
16 Rule 26.12 of the Rules relevantly states:
26.12 Discontinuance
(1) A party claiming relief may discontinue a proceeding in whole or in part by filing a notice of discontinuance, in accordance with Form 48.
(2) The party may file the notice of discontinuance:
(a) without the leave of the Court or the other party's consent:
(i) at any time before the return date fixed in the originating application; or
(ii) if the proceeding is continuing on pleadings - at any time before the pleadings have closed; or
(b) with the opposing party's consent - before judgment has been entered in the proceeding; or
(c) with the leave of the Court - at any time.
…
(7) Unless the terms of a consent or an order of the Court provide otherwise, a party who files a notice of discontinuance under subrule (2) is liable to pay the costs of each other party to the proceeding in relation to the claim, or part of the claim, that is discontinued.
17 In Lo v Australian Community Pharmacy Authority [2013] FCA 639, Katzmann J stated at [60]:
This rule, which in substance is the same as r 42.19 of the Uniform Civil Procedure Rules 2005 (NSW), establishes a default or prima facie position (Armstrong v Australian Community Pharmacy Authority [2012] FCA 577 per Rares J at [9]). It does not create a presumption that costs will be awarded against the discontinuing party, but it puts an onus on it to make an application to the Court where, absent an agreement to the contrary, it does not propose to pay the costs of the other parties (Foukkare v Angreb Pty Ltd [2006] NSWCA 335 at [65]). And the Court will require "some sound positive ground or good reason for departing from the ordinary course": Australiawide Airlines Ltd v Aspirion Pty Ltd [2006] NSWCA 365 at [54], Bitannia Pty Ltd v Parkline Constructions Pty Ltd [2009] NSWCA 32 at [54].
18 In El-Debel v Secretary, Department of Immigration and Border Protection (2014) 141 ALD 611; [2014] FCA 474, Foster J expressed the policy behind r 26.12(7) as follows at [17]:
[Rule] 26.12(7) reflects a more general policy of the law to the effect that a party should always be permitted to discontinue its proceedings but, in the modern setting, should usually have to pay the costs of the other parties occasioned by the bringing of the proceedings and their subsequent abandonment. This is not to gainsay the broad discretion in respect of costs given to the Court by s 43 of the Federal Court of Australia Act 1976 (Cth). Nonetheless, the Court should give effect to this general policy when making costs orders unless there is some good reason for declining to do so.
