“Their Lordships therefore consider that a judge should not entertain an application of which no notice has been given unless either giving notice would enable the defendant to take steps to defeat the purpose of the injunction (as in the case of Mareva or Anton Piller order) or there has been literally no time to give notice before the injunction is required to prevent the threatened wrongful act.”
“should only be made where it is essential that the plaintiff should have inspection so that justice can be done between the parties: and when, if the defendant were forewarned, there is a grave danger that vital evidence will be destroyed, that papers will be burnt or lost or hidden, or taken beyond the jurisdiction, and so the ends of justice be defeated: and when the inspection would do nor real harm to the defendant or his case… We are prepared, therefore, to sanction its continuance, but only in an extreme case where there is grave danger of property being smuggled away or of vital evidence being destroyed.”
“There are three essential preconditions for the making of such an order, in my judgment. First, there must be an extremely strong prima facie case. Secondly, the damage, potential or actual, must be very serious for the applicant. Thirdly, there must be clear evidence that the respondents have in their possession incriminating documents or things, and that there is a real possibility that they may destroy such material before any application inter partes can be made.”
“The phrase ‘a real possibility’ [used by Ormond L.J] is to be contrasted with the extravagant fears which seem to afflict all plaintiffs who have complaints of breach of confidence, breach of copyright or passing off. Where the production and delivery up of documents is in question, the courts have always proceeded, justifiably, on the basis that the overwhelming majority of people in this country will comply with the court’s order, and that defendants will therefore comply with orders to, for example, produce and deliver up documents without it being necessary to empower the plaintiff’s solicitors to search the defendant’s premises.”
“Even in cases in which the plaintiff has strong evidence that an employee has taken what is undoubtedly specific confidential information, such as a list of customers, the court must employ a graduated response. To borrow a useful concept from the jurisprudence of the European Community, there must be proportionality between the perceived threat to the plaintiff’s right 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 an Anton Piller order. People whose commercial morality allows them to take a list of the customers with whom they were in contact while employed 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. In many cases it will therefore be sufficient to make an order for delivery up of the plaintiff’s documents to his solicitor or, in cases in which the documents belong to the defendant but may provide evidence against him, an order that he preserve the documents pending further order, or allow the plaintiff’s solicitor to make copies. The more intrusive orders allowing searches of premises or vehicles require a careful balancing of, on the one hand, the plaintiff’s right to recover his property or to preserve important evidence against, on the other hand, violation of the privacy of a defendant who has had no opportunity to put his side of the case. it is not merely that the defendant may be innocent. The making of an intrusive order ex parte even against a guilty defendant is contrary to normal principles of justice and can only be done when there is a paramount need to prevent a denial of justice to the plaintiff. The absolute extremity of the court’s powers is to permit a search of a defendant’s dwelling house, with the humiliation and family distress which that frequently involves.”
“The principal dilemma about the grant of interlocutory injunctions, whether prohibitory or mandatory, is that there is by definition a risk that the court may make the “wrong” decision, in the sense of granting an injunction to a party who fails to establish his right at the trail (or would fail if there was a trial) or alternatively, in failing to grant an injunction to a party who succeeds (or would succeed) at trial. A fundamental principle is therefore that the court should take whichever course appears to carry the lower risk of injustice if it should turn out to have been “wrong” in the sense I have described. The guidelines for the grant of both kinds of interlocutcry injunctions are derived from this principle.”
“The order which I was asked to make by the present plaintiffs is a strong order, albeit less stringent than that ordered in Anton Piller by the Court of Appeal. It does not involve entry on C’s premises, but that C should hand over the infringing articles for save custody. It is a form of relief which the court will grant with great reluctance and which should seldom be sought and more seldom granted.”
“In particular, as was made clear by Hoffmann J in Lock v Beswick, the balancing act that must be undertaken prior to the grant of an order may more easily fall in favour of an applicant where the Defendant’s premises are not being searched and his privacy not being invaded.”
“In my view the principles to be applied are these: First, this being an interlocutory matter, the overriding consideration is which course is likely to involve the least risk of injustice if it turns out to be “wrong” in the sense described by Hoffmann J. Secondly, in considering whether to grant a mandatory injunction, the court must keep in mind that an order which requires a party to take some positive step at an interlocutory stage, may well carry a greater risk of injustice if it turns out to have been wrongly made than an order which merely prohibits action, thereby preserving the status quo. Thirdly, it is legitimate, where a mandatory injunction is sought, to consider whether the court does feel a high degree of assurance that the plaintiff will be able to establish his right at a trial. That is because the greater the degree of assurance the plaintiff will ultimately establish his right, the less will be the risk of injustice if the injunction is granted. But, finally, even where the court is unable to feel any high degree of assurance that the plaintiff will establish his right, there may still be circumstances in which it is appropriate to grant a mandatory injunction at an interlocutory stage. Those circumstances will exist where the risk of injustice if this injunction is refused sufficiently outweigh the risk of injustice if it is granted.”
“133. The Confidential information which Aris, Ali, Ismail and Stephen have taken is wider ranging, highly sensitive and would cause very serious damage to our business if it was provided to a competitor. The JK Foods supplier and customer portfolio has taken my family 40 years to build up; the Hyperama customer and product list has been built and refined for over 25 years. If this confidential information is provided to a competitor it would cause very serious harm to those businesses. 134. Our Industry is very competitive and margins are relatively low. If a competitor had access to the information taken by Aris and Ali (and Stephen and Ismail) it would allow them to compete with us in a way that would make it very difficult for us to compete. As such the potential loss is significant and we bring this application in the hope of restraining the unlawful use of our confidential information.”
