“The phrase “good cause” was used in Pet Plan Limited by Nicholls LJ at p.41. Nicholls LJ said that what are “good grounds” will depend upon all the circumstances of the case; see p.40. Although Buckley LJ in Chanel v Woolworth had not put the matter as broadly as this, instead saying (at p.492-3) that there had to be a significant change of circumstances or the discovery of some new facts which could not reasonably have been known about when the undertaking was given, I accept, following Pet Plan Limited, that what is “good cause” will depend upon all the circumstances of the case, though typically a change of circumstances or the discovery of some new fact will be required. In Secretary of State for Trade and Industry v Bell Davies Trading [2005] 1 AER 324 at §104 the Court of Appeal put the matter this way: “The normal procedure would be for the party, who had given the undertaking, to apply to the court, to which he had given the undertaking, on a specific ground, usually changed circumstances making the continuation of the undertaking unnecessary, oppressive or unjust.”
“Care must be taken if a defendant consents to give undertakings but wishes to preserve his right to apply to be released from them at a later date. Where a defendant chooses not to seek an adjournment of an application for an interim injunction, but instead accepts that it should be dealt with there and then by his offering undertakings until trial or further order, there must be good grounds before he can apply to modify or change them.”
“the Fourth Respondent may make any application to modify or release the Return Date Undertakings without showing good cause for making any such application, without prejudice to the Applicants’ right, as expressly reserved at the hearing, to assert that any such application would be an abuse of process.”
“All this is complex, and we need to write it all up quickly and calmly, we’re really tilting at windmills, I think, to be frank. Because, well, I think that there will be no problems overall. Respectively, we have a proposal, that if our terms in the amendments to the offer not the issue are not accepted through no fault of ours, then we will extend for a maximum of 6 months to rectify the problem, and if that does not happen, we will take it back.”
“(1) Where the court accepts that there is a good arguable case that a respondent engaged in wrongdoing against the applicant relevant to the issue of dissipation, that holding will point powerfully in favour of a risk of dissipation. (2) In such circumstances, it may not be necessary to adduce any significant further evidence in support of a real risk of dissipation; but each case will depend upon its own particular facts and evidence.”
“2. What arguable causes of action arise against the Mints family as a matter of Russian civil law and what are the ingredients for establishing those causes of action?[…]”
“Rix J. was careful to limit his remarks to legal professional privilege and it is far from obvious that these concerns should be added to the heavy responsibilities already undertaken by lawyers who are making a without notice application, except perhaps in circumstances where the evidence in question is of central importance to the application. Even when the evidence is of central importance (for example, evidence as to the sale of contraband goods in a case of piracy of intellectual property rights) “trap orders” and other conduct involving impersonation or deception have been commonplace in the Chancery Division for a century or more, and do not seem to have attracted censure.”
