General principles
25 A number of the general principles relevant to the strike out application were recently summarised in KTC at [113] - [132] per Wigney J), [329] (per Anastassiou J, in dissent on the outcome, but not on the general principles), [418] (per Jackson J). These principles, together with some additional relevant principles, are as follows.
(1) Rules 16.02 and 16.21 must be interpreted and applied in light of the overarching purpose of the civil practice and procedure provisions identified in s 37M of the FCA Act; namely, to facilitate the just resolution of disputes according to law as quickly, inexpensively and efficiently as possible: KTC at [118].
(2) As to r 16.02(1)(d) and the requirement that the pleading state the 'material facts' relied on, the material facts must be pleaded with a degree of specificity which is sufficient to convey to the opposite party the case that it has to meet and that a 'bare conclusion' is ordinarily not a proper allegation. A pleading that simply pleads a conclusion is embarrassing and should not be permitted to stand: KTC at [114] citing Allstate Life Insurance Co v Australia and New Zealand Banking Group Ltd [1994] FCA 636; (1994) 217 ALR 226 at 235; Young Investments Group Pty Ltd v Mann [2012] FCAFC 107 at [7]; (2012) 293 ALR 537. See, also, H 1976 Nominees Pty Ltd v Galli (1979) 30 ALR 181 at 186-187. The same may be said of a failure to state the provisions of any statute relied on, as required by r 16.02(1)(e), where it results in a failure to give adequate notice of the case to be met.
(3) Rules 16.42 and 16.43 are also relevant. Rule 16.42 provides that a party who pleads fraud, misrepresentation, unconscionable conduct, breach of trust, wilful default or undue influence, must state in the pleading particulars of the facts on which the party relies: KTC at [115]. As noted earlier in these reasons, it is 'fundamental, and long established, that if a case of fraud is to be mounted, it should be pleaded specifically and with particularity': Forrest at [26]; KTC at [116]. Similarly, r 16.43(1) provides that a party who pleads a condition of mind must state in the pleading particulars of the facts at which the party relies.
(4) As to r 16.21(1)(a) (scandalous material), a mere allegation of scandalous fact does not render the pleading liable to be struck out for containing scandalous material. The scandalous material will not be struck out unless it is also irrelevant: Christie v Christie (1873) LR 8 Ch App 499 at 503; Blake v Albion Life Assurance Society (1876) 45 LJCP 663 at 666. Material is 'scandalous' if, as well as being irrelevant, it is indecent or offensive or consists of allegations made for the purpose of abusing or (possibly) prejudicing the opposite party: Cashin v Craddock [1876] 3 Ch D 376 at 378-379. It has also been said that scandal consists in the allegation of 'anything which is unbecoming to the dignity of the Court to hear or is contrary to good manners or which charges some person with a crime not necessary to be shown in the cause, to which may be added that any unnecessary (not relevant to the subject) allegation bearing cruelly upon the moral character of an individual': Hongkong Xinhe International Investment Co Ltd v Bullseye Mining Ltd (No 3) [2021] WASC 260 at [61] citing Legal Practice Board v Said (unreported, WASC, Library No 940003, 12 January 1994) at 3.
(5) As to r 16.21(1)(b) (frivolous or vexatious material), the word 'vexatious' in the context of rules such as r 16.21 is an 'omnibus expression' that includes material which is scandalous, discloses no reasonable cause of action, is oppressive or embarrassing, or the inclusion of which is otherwise an abuse of the processes of the Court: Gallo v Attorney-General (Vic) (unreported, Supreme Court of Victoria, Full Court, Starke J, with whom Crockett and Beach JJ agreed at 12, 4 September 1984), referred to with approval in Mathews v State of Queensland [2015] FCA 1488 at [87]; KTC at [119].
(6) Material in a pleading would also be considered to be vexatious or frivolous if it was included in the pleading with the intention of annoying or embarrassing, or for a collateral purpose, or if it raises matters that are 'obviously untenable or manifestly groundless': Attorney-General v Wentworth (1988) 14 NSWLR 481 at 491; see also Von Reisner v Commonwealth (2009) 177 FCR 531; [2009] FCAFC 97 at [27]; KTC at [119].
(7) A proceeding is not frivolous if there is a triable issue; it is frivolous if it is obviously not sustainable: Young v Holloway [1895] P 87 at 90-91. An obviously unsustainable claim may also be characterised as vexatious: Peruvian Guano Co Ltd v Bockwoldt (1883) 23 Ch D 225 at 230. Proceedings that are foredoomed to fail (i.e., frivolous and (or) vexatious) may also be characterised as an abuse of the process of the Court: Walton v Gardiner (1993) 177 CLR 378 at 392-393. However, the concept of abuse of process is not confined to proceedings that are untenable.
(8) As to r 16.21(1)(d) (prejudice, embarrass or delay), a pleading is likely to cause prejudice or embarrassment if it is susceptible to various meanings, contains inconsistent allegations, includes various alternatives which are confusingly intermixed, contains irrelevant allegations or includes defects which result in it being unintelligible, ambiguous, vague or too general: Bartlett v Swan Television & Radio Broadcasters Pty Ltd [1995] ATPR 41-434 at 40,889; Spiteri v Nine Network Australia Pty Ltd [2008] FCA 905 at [22]; Fair Work Ombudsman v Eastern Colour Pty Ltd [2011] FCA 803 at [18]; Shelton v National Roads and Motorists Association Ltd (2004) 51 ACSR 278; [2004] FCA 1393 at [18]; KTC at [120]. Such a pleading could equally be characterised as evasive or ambiguous for the purposes of r 16.21(1)(c): KTC at [120].
(9) A pleading may also be struck out as embarrassing if it is plain that the pleading party cannot lawfully call any evidence at the hearing to substantiate the pleading: J C Techforce Pty Ltd & Steinhardt v Pearce, Neville & Oke Industrial Pty Ltd (1996) 138 ALR 522 at 531; KTC at [122]. Such a pleading may also be struck out under r 16.21(1)(b) (frivolous or vexations) or 16.21(1)(f) (abuse of the process) on the ground that the allegations are foredoomed to fail if they are not able to be proved: Pihiga Pty Ltd v Roche [2011] FCA 240 at [71], [76] - [79] see, also, DC Payments Pty Ltd v Next Payments Pty Ltd [2016] VSC 315; (2016) 51 VR 151 at [82] - [85].
(10) While a point of law may be raised in accordance with r 16.02(3), it is not necessary to plead assertions or conclusion of law. Further, there is authority for the proposition that conclusion of law should not be pleaded, except by way of clarification of a case already pleaded by reference to material facts: Allstate at 235. Nonetheless, it is common to plead assertions or conclusions of law as a means of identifying the cause(s) of action alleged to support the relief claimed or defence. In other words, it may be necessary in complicated or complex cases to plead conclusions of law fairly to inform the other party of the case to be met. However, epithets such as 'wrongfully', 'unlawfully' and 'improperly' add nothing to a pleading. Any legal conclusion of wrongfulness, unlawfulness or impropriety is to be derived from the pleaded material facts alone. In the absence of such material facts, the pleading is bad and liable to be struck out for pleading unsupported conclusions: Day v Brownrigg (1878) 10 Ch D 294 at 302.
(11) As to r 16.21(1)(e) (failure to disclose a reasonable cause of action), a 'reasonable cause of action' is a cause of action that has some chance of success having regard to the allegations pleaded. A cause of action cannot be struck out merely on the basis that it appears to be weak: KTC at [123], citing Polar Aviation Pty Ltd v Civil Aviation Safety Authority (2012) 203 FCR 325; [2012] FCAFC 97 at [42]-[43]; Allstate at 236.
(12) A pleading may be struck out for disclosing no reasonable cause of action if, accepting all material facts pleaded as true and that on all other points (except points of law) the pleading is unassailable, it would not be open to the party upon the pleading to prove facts at trial that would constitute a cause of action or defence: Pancontinental Mining Ltd v Posgold Investments Pty Ltd (1994) 121 ALR 405 at 414; Mutual Life & Citizens' Assurance Co Ltd v Evatt [1970] UKPCHCA 2; (1970) 122 CLR 628 at 631.
(13) Inevitably, there is overlap between applications to strike out a pleading on the ground that it fails to disclose a reasonable cause of action under r 16.21(1)(e) and the grounds in r 16.21(1)(c) and r 16.21(1)(d) where pleadings omit material facts and (or) plead conclusions that are not supported by material facts. Depending on the nature and degree of the omission such deficiencies may be characterised as one or more of a failure to disclose a cause of action or defence, evasive or ambiguous or likely to prejudice, embarrass or delay the proceedings.
(14) As to r 16.21(f) (abuse of process), the High Court has said that what amounts to an abuse of the process of the Court is 'insusceptible of a formulation comprising closed categories' and 'the possible varieties of abuse of process are only limited by human ingenuity': Batistatos v Roads Traffic Authority (NSW) [2006] HCA 27; (2006) 226 CLR 256 at [9]; Sea Culture International Pty Ltd v Scoles (1991) 32 FCR 275 at 279. There are many other authorities to the same or similar effect.
(15) In general, abuse of process will exhibit at least one of three characteristics: PNJ v The Queen [2009] HCA 6; (2009) 252 ALR 612 at [3]:
(a) the court's process is invoked for an illegitimate or collateral purpose;
(b) use of the court's procedures would be unjustifiably oppressive to a party; or
(c) use of the court's procedures would bring the administration of justice into disrepute.
The concept extends 'to all those categories of cases in which the processes and procedures of the court, which exist to administer justice with fairness and impartiality, may be converted into instruments of injustice or unfairness': Walton at 392-393.
(16) Although evidence may be, and often is, adduced in support of an application to strike out a pleading or proceeding on the ground of abuse of process, it is not necessary for an abuse of process to be proven by admissible evidence. An abuse of process may be manifest on the face of a pleading or other document filed in the Court. A document that 'contains matter that is scandalous, vexatious or oppressive' may be struck out of the document: r 6.01(b) of the Rules. Likewise, a pleading that 'contains' scandalous, frivolous or vexatious material or that is 'otherwise' an abuse of the process of the Court may be struck out in whole or in part: rr 16.21(1)(a) - (b), (f) of the Rules. Thus, the Court may strike out a pleading or proceeding as an abuse of process without evidence of abuse: e.g., Manolakis at [3] - [6] and [28] (insufficient information to support allegations of fraud or criminal conduct); Hodson v Pare [1899] 1 QB 455 (alleged defamation pleaded in circumstances of absolute privilege).
(17) An applicant that has commenced proceedings founded on information obtained or used in breach of a duty of confidence may be restrained from continuing with or utilising the information in the proceedings: Glencore International AG v Federal Commissioner of Taxation [2019] HCA 26; (2019) 265 CLR 646 at [6]; Lord Ashburton v Pape [1913] 2 Ch 469 at 472-477; Moorgate Tobacco Co Ltd v Philip Morris Ltd (No 2) (1984) 156 CLR 414 at 437-438; Commonwealth v John Fairfax & Sons Ltd (1980) 147 CLR 39 at 50; Pihiga at [76], [77], [97], [109] - [111]; Sullivan v Sclanders [2000] SASC 273; (2000) 77 SASR 419 at [1], [3], [31], [71]; AG Australia Holdings Ltd v Burton [2002] NSWSC 170; (2002) 58 NSWLR 464 at [129] - [163], [168], [169], [214], [215], [222], [223] (as to the form of orders made, see AG Australia Holdings Ltd v Burton [2002] NSWSC 454 at [59]). A third party whose conscience is relevantly affected may also be restrained: Johns v Australian Securities Commission (1993) 178 CLR 408. That may include, in appropriate circumstances, restraining a party's legal advisors from acting in proceedings where the legal advisors have received confidential information: Michael Smith Real Estate Pty Ltd t/as Raine & Horne Marrickville v Chmait [2021] NSWSC 1160. The duty of confidence may arise from agreement (express or implied) or equity: AG Australia at [73].
(18) In keeping with the overarching purpose identified in s 37M of the FCA Act, it is not necessary to commence separate proceedings or make an interlocutory application for injunctive relief if alternative orders that sufficiently protect and maintain the confidentiality of the information can be made: Expense Reduction Analysts Group Pty Ltd v Armstrong Strategic Management and Marketing Pty Ltd [2013] HCA 46; (2013) 250 CLR 303 at [56] - [63], [69].
(19) A pleading founded on misuse of confidential information may be struck out on the ground that the order should be made to deny the wrongdoer the benefit of using the confidential information and to ensure that no advantage is obtained in the litigation arising from the breach of confidence: DC Payments at [74] - [81], [85]; Sullivan at [1], [3], [31], [71]. An order striking out a pleading on the ground that it was drawn in breach of a duty of confidence may also be justified on the ground that to permit such a pleading to stand would involve an abuse of the process of the Court.
(20) A person may also be restrained from relying upon or using confidential without prejudice communications in legal proceedings in breach of the express or implied agreement to maintain the confidentiality of and not adduce evidence of the communications: Pihiga at [71], [76], [77], [97], [109] - [111].
(21) If substantial parts of a pleading are struck out, the Court may strike out the entire pleading on the basis that the 'residue would be confusing': Trade Practices Commission v Australian Iron & Steel Pty Ltd (1990) 22 FCR 305 at 323: KTC at [124].
(22) Where summary dismissal of the whole or part of a proceeding would result, the power to strike out should be exercised only in plain and obvious cases, where no reasonable amendment could cure the alleged defect or deficiency. The power is discretionary and should be employed sparingly and only in a clear case lest a party is deprived of a case which in justice it ought to be able to bring: KTC at [125], citing Allstate at 236; Trade Practices Commission v Pioneer Concrete (Qld) Pty Ltd (1994) 52 FCR 164 at 175.
26 As Mr Pigozzo placed considerable reliance and emphasis on the last general principle referred to above and submitted, in effect, that the Court should not strike out any part of the statement of claim unless satisfied that there was no real question to be tried and that any defect could not be cured by reasonable amendment, it is necessary to identify an important qualification to that principle where, as here, the power to strike out a pleading will not have the effect of summarily dismissing a cause of action or defence of a party. The statement of principle in KTC (and the many other authorities to the same or similar effect) is to be understood in the context that the order under appeal in KTC was the dismissal of an application for leave to amend a statement of claim to re-plead a cause of action that had been struck out as the result of a previous order of the Court. Therefore, the effect of the decision to refuse leave to amend was to 'to strike out' and 'summarily dismiss' the cause of action in the proposed amended statement of claim. Other authorities in which the same or a similar statement of principle has been made were also concerned with striking out pleadings coupled with summary dismissal of all or part of the proceedings.
27 Subsection 31A(2) of the FCA Act relevantly provides that the Court may give judgment for a party if the Court is satisfied that the other party has no reasonable prospect of successfully prosecuting the proceeding. Rule 26.01 of the Rules, which also deals with summary judgment, provides that a party may apply to the Court for an order that judgment be given against another party on grounds that essentially mirror the grounds for striking out a pleading in r 16.21(1) of the Rules: KTC at [127].
28 The relevant principles in relation to summary judgment or dismissal under s 31A of the FCA Act were considered by the High Court in Spencer v The Commonwealth [2010] HCA 28; (2010) 241 CLR 118; and have been discussed in numerous judgments in this Court. In KTC they were summarised as follows (at [128] - [132]).
(1) Section 31A of the FCA Act authorises summary disposition of proceedings 'on a variety of bases under its general rubric', including, but not limited to: where the pleading discloses no reasonable cause of action and the deficiency in that regard is 'incurable'; where 'there is unanswerable or unanswered evidence of a fact fatal to the pleaded case and any case which might be propounded by permissible amendment'; and the 'longstanding category of cases which are "frivolous or vexatious or an abuse of process"': Spencer at [22] (French CJ and Gummow J).
(2) The power to summarily dismiss a proceeding is to be distinguished, in its application to deficient pleadings, from rules such as r 16.21 of the Rules: Spencer at [23] (French CJ and Gummow J). Where the evidence shows that a person may have a reasonable cause of action or reasonable prospects of success, but the person's pleading does not disclose that to be the case, the Court may be empowered to strike out the pleading under r 16.21, but is not empowered to summarily dismiss the proceeding under s 31A of the FCA Act: see White Industries Aust Ltd v Commissioner of Taxation [2007] FCA 511; (2007) 160 FCR 298 at [47], referred to in Spencer at [23]. That said, a 'failure after ample opportunity to plead a reasonable cause of action may suggest that none exists and therefore that the applicant has no reasonable prospects of success': White Industries at [47].
(3) An applicant may have no reasonable prospect of successfully prosecuting the proceeding even if it cannot be concluded that the proceeding is hopeless or bound to fail: Spencer at [17] (French CJ and Gummow J). The inquiry required under s 31A is 'not an inquiry directed to whether a certain and concluded determination could be made that the proceeding would necessarily fail': Spencer at [52] (Hayne, Crennan, Kiefel and Bell JJ).
(4) The 'exercise of powers to summarily terminate proceedings must always be attended with caution', whatever may be the basis upon which that disposition is sought: Spencer at [24] (French CJ and Gummow J). It is not a power 'to be exercised lightly': Spencer at [60] (Hayne, Crennan, Kiefel and Bell JJ). There must be a 'high degree of certainty about the ultimate outcome of the proceeding if it were allowed to go to trial in the ordinary way': Batistatos at [46], referred to in Spencer at [24] (French CJ and Gummow J).
29 As striking out a pleading for failing to disclose a cause of action under r 16.21(1)(e) involves a different question to that concerned in an application under s 31A of the FCA Act and (or) r 26.01 of the Rules, a pleading may be struck out under r 16.21(1)(e) even though the defect may be cured by reasonable amendment or there may be a real question to be tried. In Chandrasekaran v Commonwealth of Australia (No 3) [2020] FCA 1629 (at [102]) Wigney J said:
The grounds upon which a pleading can be struck out under r 16.21 of the Rules correspond, to a large extent, with the grounds upon which a proceeding may be summarily dismissed under s 31A of the FCA Act and r 26.01 of the Rules. The Court will proceed to strike out under r 16.21, rather than summarily dismiss the proceeding under r 26.01 of the Rules, where although there are deficiencies in the pleading, a reasonable case may still exist. The granting of leave to replead in those circumstances may allow the applicant to remedy the deficiencies.
30 On an application for summary dismissal of a proceeding under s 31A or r 26.01 of the Rules, evidence may be admitted to demonstrate that there is, or is not, a reasonable cause of action or defence: Dey v Victorian Railways Commissioners (1949) 78 CLR 62 at 109; Thorpe v Commonwealth of Australia (No 3) (1997) 144 ALR 677 at 681-682. However, on an application to strike out on the ground that a pleading fails to disclose a reasonable cause of action (or defence), except for documents referred to in or that from part of the pleading, no evidence is admissible: Day v William Hill (Park Lane) Ltd [1949] 1 KB 632 at 639. Otherwise, all facts alleged in the statement of claim must be accepted as true and on all other points (except points of law) the pleading as unassailable: Niven v Grant (1903) 29 VLR 102 at 106.
31 It follows that the general principles on an application to strike out for failing to disclose a reasonable cause of action, as expressed in KTC (at [125]), in Allstate at 235-236 and Polar Aviation at [42] - [43], are to be read and understood in the context that those decisions involved striking out pleadings and summary dismissal of the proceedings (or equivalent). These authorities demonstrate that a pleading may be struck out on the ground that it fails to disclose a reasonable cause of action or defence with the Court also being satisfied that there is no real question to be tried or no reasonable amendment could cure the defect resulting in summary dismissal of the proceedings.
32 A pleading may also be struck out for failing to disclose a reasonable cause of action or defence, but the party may be given leave to re-plead if the Court is satisfied that the party may be able to plead a viable cause of action or defence with 'reasonable amendment': e.g., Elston v Commonwealth of Australia [2013] FCA 108 at [31] - [32], [47] - [48]. Nonetheless, a 'failure after ample opportunity to plead a reasonable cause of action may suggest that none exists and therefore that the applicant has no reasonable prospect of success': White Industries at [47]. In such a case, leave to re-plead may be refused and (or) the proceedings summarily dismissed: see, e.g., Young Investments Group Pty Ltd v Stripe Capital Pty Ltd [2010] FCA 996 at [37], [45], [54], [60], [62]; Young Investments Group Pty Ltd v Stripe Capital Pty Ltd [2011] FCA 1147 at [49]; Young Investments Group Pty Ltd v Mann [2012] FCAFC 107; (2012) 293 ALR 537 at [2], [61], [62]; Polar Aviation Pty Ltd v Civil Aviation Safety Authority (No 4) [2011] FCA 1126; (2011) 203 FCR 293 at [124] - [125]; Polar Aviation at [85] - [89], [93]; see, also, J & A Vaughan Super Pty Ltd (Trustee) v Becton Property Group Ltd [2014] FCA 581 at [18].
33 MRL and Mr Ellison have not applied or submitted that Mr Pigozzo's causes of action against them should be struck out and summarily dismissed. Therefore, the question for the Court is whether, accepting the pleaded facts as true, it is plain and obvious that the statement of claim should be struck out for failing to disclose a reasonable cause of action or on some other ground in r 16.21(1).
