“(1) The court may make an order under this section for the purpose of securing, in the case of any existing or proposed proceedings in the court—(a) the preservation of evidence which is or may be relevant, or (b) the preservation of property which is or may be the subject-matter of the proceedings or as to which any question arises or may arise in the proceedings. (2) A person who is, or appears to the court likely to be, a party to proceedings in the court may make an application for such an order. (3) Such an order may direct any person to permit any person described in the order, or secure that any person so described is permitted—(a) to enter premises in England and Wales, and (b) while on the premises, to take in accordance with the terms of the order any of the following steps. (4) Those steps are—(a) to carry out a search for or inspection of anything described in the order, and (b) to make or obtain a copy, photograph, sample or other record of anything so described. (5) The order may also direct the person concerned—(a) to provide any person described in the order, or secure that any person so described is provided, with any information or article described in the order, and (b) to allow any person described in the order, or secure that any person so described is allowed, to retain for safe keeping anything described in the order. (6) An order under this section is to have effect subject to such conditions as are specified in the order. (7) This section does not affect any right of a person to refuse to do anything on the ground that to do so might tend to expose him or his spouse or civil partner to proceedings for an offence or for the recovery of a penalty. (8) In this section— "court" means the High Court, and "premises" includes any vehicle; and an order under this section may describe anything generally, whether by reference to a class or otherwise.”
"(1) the Court may grant the following interim remedies ... (h) an order referred to as a 'search order' under section 7 of the [1997 Act] (order requiring a party to admit another party to premises for the purposes of preserving evidence et cetera)."
“Although in the Anton Piller case Lord Denning spoke of “an extreme case”, in practice orders are granted far too routinely for them to be regarded as exceptional. However, the court still insists on a clear showing of fraud, dishonesty, contumacy, or imminent removal or destruction of property or evidence. The overriding principle is that of necessity. No order ought to be made unless it is necessary in the interests of justice. The so-called “balance of convenience” test, which plays a leading role in most decisions to grant interlocutory injunctions, has little, if any role to play in an application to grant a search order. Consistent with the principle of necessity, the cases have established the following conditions for the making of an order (see 1992 Consultation Paper, paras 2.4, et seq., and the summary in Indicii Salus Ltd v. Chandrasekaran[2006] EWHC 521 (Ch) , February 15, 2006, unrep. (Warren J.)). (1) There must be a strong prima facie case of a civil cause of action. Suspicion that there may be a cause of action should not be enough. A scrutiny of the merits of the claimant’s case is an essential preliminary to the grant of a search order. It is not sufficient for the applicant to show merely a “serious question to be tried” (as is sufficient in applications for orthodox interlocutory injunctions). (2) The danger to the claimant to be avoided by the grant of an order must be serious. If an order is sought in order to forestall the destruction of evidence, the evidence in question must be of major, if not critical, importance. (3) There must be clear evidence that the defendants had in their possession incriminating documents or things. (4) The risk of destruction or removal of evidence must be a good deal more than merely possible. (In Booker McConnell v. Plascow Plc[1985] RPC 425 at 441, CA, Dillon LJ referred to “a real possibility”, which he contrasted with “extravagant fears which seem to afflict all claimants who have complaints of breach of confidence, breach of copyright or passing-off”.) The fact that a respondent can be shown to have behaved improperly will not always justify an order. There must be a real reason to believe that the respondent will disobey an injunction for the preservation of the evidence in question. (5) The harm likely to be caused by the execution of the order to the respondent and his business affairs must not be excessive or out of proportion to the legitimate object of the order. This precondition is particularly relevant where the seizure of trading stock or the perusal by the claimant of confidential commercial documents will be the effect of execution of the order and is strongly analogous to the principle of proportionality as applied by the European Court of Human Rights. If any of these pre-conditions is absent, the weight of judicial authority suggests that an application for the grant of a search order should be refused. If each of these preconditions appears to be present, an order will not necessarily be justified. The court will still have to weigh in the balance the claimant’s need for the order against the injustice to the respondent in making the order ex parte without any opportunity for the respondent to be heard. The judge who hears the application for the order should keep in mind that, in as much as audi alteram partem is a requirement of natural justice, the making of an ex parte mandatory order always risks injustice to the absent and unheard respondent. The order should not be made unless it appears that, without the order, the claimant will be likely to suffer a greater injustice than that which the court, by making the order, will be inflicting on the respondent (see Columbia Picture Industries v. Robinson[1987] Ch 38 ;[1986] 3 WLR 542 ;[1986] 3 All ER 338 ). The court requires proportionality between the perceived threat to the claimant’s rights and the remedy granted. The fact that there is overwhelming evidence that the defendant has behaved wrongfully in his commercial relationships does not necessarily justify a search order. People whose commercial morality allows them to take a customer list will not necessarily disobey an order of the court requiring them to deliver it up. Not everyone who is misusing confidential information will destroy documents in the face of a court order requiring him to preserve them (Lock International Plc v. Beswick[1989] 1 WLR 1268 ,[1989] 3 All ER 373 ) (Hoffmann J.)).”
“(1) a combination of two or more persons wilfully to injure a man in his trade is unlawful and, if it results in damage to him, is actionable. (2) if the real purpose of the combination is not to injure another but to forward or defend the trade of those who enter into it, then no wrong is committed and no action will lie, although damage to another ensues.”
"Legitimate and illegitimate objects 24-109 ... a genuine belief that [legitimate] objectives are the object and likely result of the combination is now enough to validate it. It is worthy of note that in some cases trade union officials have escaped liability for conspiracy to injure by reason of the fact that they acted in order 'to forward what they believed to be the interests of the union and fundamental trade union principle' [Stratford & Son Ltd v Lindley [1965] A.C. 269 at 323]. That genuinely held belief is sufficient to establish pursuit of a legitimate interest even if damage to the employer is known to be inevitable and is even intended. 24-110 The action taken should not exceed what is necessary for the protection of such legitimate interest and although liability is not to be determined by asking whether the damage inflicted is disproportionate to the objective 'this had may throw doubt on the bona fides of the avowed purpose' [Crofter at 447 per Viscount Simon]. To be legitimate it is not necessary that the interests should be material in that they can be exchanged for cash ... 24-111 On the other hand, Quinn v Leathem [1901] A.C. 495 shows that a combination is wrongful if the real object is an intention to injure ... if the object is to injure the claimant by way of punishing him or by way of compelling him to pay a debt, it is an actionable conspiracy ... action taken in pursuit of political goals (other than those which are proscribed by legislation) might possibly be seen as pursuit of a legitimate objective ... Mixed objectives and predominant purpose 24-112 It is plain that a combination may have more than one object or purpose. If so 'liability must depend on ascertaining the predominant purpose'. If that predominant purpose is to damage another person and damage results, that is a tortious conspiracy. If the predominant purpose is the lawful protection or promotion of any lawful interests of the combiners (no illegal means being employed) it is not a tortious conspiracy, even though it causes damage to another person [Crofter at 447 per Viscount Simon]. In ascertaining the predominant purpose the Court can have regard to both the short and the long-term objectives of the combiners. Disparity of interests and objects 24-113 To be legitimate there need not be 'a complete identity of interest between parties to a combination', but there must be 'sufficient identity of object, though advantage to be derived from that same object may not be the same' [Crofter at 479 per Lord Wright] ... it has been said however that if a conspiracy be once established 'the actions of any one of them (ie the conspirators) in furtherance of the objects of their conspiracy will be treated as the actions of all of them' [EC Thompson & Co Ltd v Deakin[1952] Ch. 646 at 674 per Evershed MR]. But where the aims or objects of the combiners are distinct and certainly where their knowledge of the facts differs, the Court does not adopt that approach to the extent of imputing the motives of one conspirator to all of the others [eg Huntley v Thornton[1967] 1 WLR 321 at 343]. A party to a combination who had a separate and predominantly vindictive or mercenary object of his aim other than trade interests might not be protected [per Lord Thankerton in Crofter at 460], but in such a case if the other parties have predominantly lawful objects of their own and he commits no unlawful act or threat, he will, even though malicious, incur no liability at all [Allen v Flood [1898] A.C. 1]. If, however, the other parties know of and countenance his vindictive purpose, they will, it is submitted, be jointly responsible with him for wrongful conspiracy [Lord Porter in Crofter at 495]. Onus of proof 24-114 The burden of proving both the combination and the purpose of damaging the claimant is normally on the claimant himself ..."
“24-98 This form of the tort is committed where two or more persons combine and take action which is unlawful in itself with the intention of causing damage to a third party who does incur the intended damage. It is not necessary for the injured party to prove that causing him damage was the main or predominant purpose of the combination but that purpose must be part of the combiners’ intentions. The main issues raised by this form of the tort are first the degree of intention required and second the ambit of unlawful means … 24-101 There is no good reason why the ambit of “unlawful means” in this form of conspiracy should not be coterminous with its scope in the other economic torts. It has been held that whenever an act is itself tortious, a combination to do that act is a tortious conspiracy [Crofter at 462, per Lord Wright] … While not all equitable wrongs appear to be unlawful means, where a serious contravention occurs it is still open to the court to regard such wrongs as unlawful means for the purposes of conspiracy [Belmont Finance Corp v. Williams Furniture Ltd (No.2)[1980] 1 All ER 393 ]. If however the overt acts alleged are not actionable in a civil action the claimant will fail to establish a cause of action for conspiracy … Other forms of unlawful means 24-106 Although the “general” approach, which finds unlawful means whenever defendants have done acts which they are not at liberty to commit such as contempt of court or even intentional misuse of confidential information to damage the claimant [Spermolin Ltd v. Winter, The Guardian,22nd June 1962 ], should not be permitted after the House of Lords decision in Lonrho v. Shell [[1982] AC 173 ], that decision does not deal directly with the treatment of wrongs other than breach of statute as unlawful means … Where a combination uses breach of confidence as part of the method of achieving its objective, that may be sufficient [Faccenda Chicken Ltd v. Fowler[1984] ICR 589 at 602, per Goulding J] …”
"Requirements 27-06 Traditionally there are three elements for liability for breach of confidence. These principles are derived from Coco v AN Clark Engineers Limited [[1969] RPC 41 ] per Megarry J [at 47]. First, the information in respect of which relief is sought must have the necessary quality of confidence about it. Secondly, the information must have been imparted in circumstances importing an obligation of confidence. The use of the word 'imparted' however is now clearly too limited for the modern action, it now being established that there is no need for an initial confidential relationship. Thirdly, there must be an unauthorised use or disclosure of that information ... Limiting principles 27-07 In Attorney General v Guardian Newspapers (No. 2) [1991] A.C. 109, Lord Goff identified three limiting principles on the duty of confidence [at 280]. First, the principle of confidentiality only applies to information to the extent that it remains confidential and once it has entered the public domain, which means no more than that the information in question is so generally accessible that in all the circumstances it cannot be regarded as confidential, then the principle of confidentiality can have no application to it. Secondly, the duty of confidence applies neither to useless information nor to trivia. Thirdly, the public interest that confidence should be preserved may be outweighed by some other countervailing public interest which favours use or disclosure, either to the world at large, or at least appropriate authorities. That may require the Court to carry out a balancing operation weighing the public interest in maintaining confidence against the public interest favouring use or disclosure. Where free speech is a concern, the impact ofArticle 10 of the ECHR will have to be addressed so that the issue becomes whether restraining disclosure of the confidential information is a justifiable interference with the Article 10 right to freedom of expression."
