The order was duly served on the defendants and, without asking for any time in which to exercise their right to take legal advice and without applying to the judge to vary or discharge the order, they complied with it. They could, if they had wished, have refused immediate compliance and instead have made an urgent application to have the order asset aside. This, in my judgment, i implicit in the final paragraph of the order which I have just read. However, I must emphasise, as did Buckley LJ in Hallmark Cards Inc v Image Arts Limited [1977] FSR 150, that defendants who take this line do so very much at their peril. If they succeed in getting the order discharged, all well and good. But if they fail, they will render themselves liable for penalties for contempt of court. If they fail and there is any reason to believe that, in the period between the time when the order has been served on them and the time they eventually comply with the order, they had taken any steps which were inconsistent with the order, they had, for example, destroyed any records, the consequences to them would be of the upmost gravity.
Subsequently (at 594), his Lordship continued:
As I have said, ex parte orders are essentially provisional in nature. They are made by the judge on the basis of evidence and submissions emanating from one side only. Despite the fact that the applicant is under a duty to make full disclosure of all relevant information in his possession, whether or not it assists his application, this is no basis for making a definitive order and every judge knows this. He expects at a later stage to be given an opportunity to review his provisional order in the light of evidence and argument adduced by the other side, and, in so doing, he is not hearing an appeal from himself and in no way the appeals inhibit him from discharging or varying his original order…In the instant case the Anton Pillar order is spent in the sense that it has been executed. However, the defendants seek to go back to the beginning of the action saying that, regardless of whether the fruits of the order are such as to show that it was abundantly justified, the judge has insufficient material to justify his action at the ex parte stage. They therefore invite us to set the ex parte order aside and order the return of the affidavits to the two personal defendants and the seized material to the defendant's solicitors. I regard this as wholly absurd. The courts are concerned with the administration of justice, not with playing a game of snakes and ladders. If it were now clear that the defendants had suffered any injustice by the making of the order, taking account of all relevant evidence, including the affidavits of the personal defendants and the fruits of the search, the defendants would have their remedy and the counter undertaking as to damages. But this is a matter to be investigated by the High Court judge who is seized of the matter and only when he has reached a decision, can this court be concerned.
13 Dunn LJ agreed, and added:
It was said on behalf of the defendants that that evidence [namely the material obtained pursuant to the order] was irrelevant and inadmissible in any application to review the order either by way of an application to discharge it or by of appeal, and that on such an application, the court should confine itself to the evidence before the judge who made the order. I do not agree with that submission. Hallmark Cards Inc v Image Arts Limited [1977] FSR 150, to which Sir John Donaldson MR has referred, shows that the court looks at the reality of the situation, including any evidence filed or statement made by counsel by way of admissions after the execution of the Anton Pillar order. If consequent on the grant of the Anton Pillar order, the applicant shows that the order was in fact justified, then the fact that the evidence before the judge was not as strong as it ultimately became does not in my view provide a ground for challenging the order itself. It does not, of course, affect the situation if the order was obtained malafide or by some material non-disclosure, but none of those matters are alleged in this case, and I too would dismiss the appeal for the reasons given by Sir John Donaldson MR.
14 Purchas LJ agreed with both of the other judgments, and added:
This appeal is concerned with the order made on 26 January 1983. For my part, I doubt that on an application to set aside an ex parte order which has become entirely spent, even if made to the court which made that order, let alone by way of appeal, the party against whom the order had been made can succeed save only in those very exceptional circumstances to which Sir John Donaldson MR and Dunn LJ have referred. I agree that if in so far as this motion purports to involve proceedings which took place on 26 January 1983 or on subsequent occasions, on those grounds it is misconceived.
