AIB PLC & Ors v Diamond & Ors
Factual and Procedural Background
The proceedings arise against the backdrop of the collapse of the Irish banking system, notably involving Company A, a banking group that became almost wholly state-owned due to financial difficulties. As part of a strategy to recapitalise, Company A sought to sell non-core assets, including an international financial services unit and related operating companies (collectively "the operating companies"). A management buyout ("MBO") proposal emerged from senior employees within these units, while a third party, Company B, also made an offer and was declared the preferred bidder. A significant reduction in the sale price was attributed, according to Company A, to a plan implemented by the defendants to transfer business and personnel from Company A's international financial services unit to a corporate entity referred to as Centralis. This plan allegedly involved defendants soliciting customers and using confidential information improperly.
Company A sought interlocutory injunctions to restrain the defendants from soliciting customers, concluding contracts, soliciting employees, and using confidential information, along with orders for the return of such information. The proceedings commenced on 6 September, with an initial limited interim injunction granted to preserve confidential materials. Subsequent interlocutory hearings were adjourned to allow further affidavits and mediation, which proved unsuccessful. Certain defendants provided undertakings leading to the discontinuance of injunction applications against them. The remaining interlocutory application concerned several personal defendants and Centralis. The court was tasked with determining the applicable law and whether interlocutory relief in the form of a springboard injunction was appropriate.
Legal Issues Presented
- Whether the applicable law governing the contractual and non-contractual obligations of the defendants is Irish law or the law of the jurisdictions where the defendants operated or where the corporate defendants are established, pursuant to Regulation (EC) No 593/2008 ("Rome I") and Regulation (EC) No 864/2007 ("Rome II").
- Whether Company A has established a strong arguable case that the defendants breached their contracts or committed tortious acts warranting interlocutory relief.
- The appropriate scope and duration of any interlocutory springboard injunction to prevent the defendants from enjoying an unlawful competitive advantage.
- The adequacy of damages as a remedy and the balance of convenience in granting or refusing interlocutory relief.
- The nature and definition of confidential information subject to injunction and return orders.

Court's Reasoning and Analysis
The court commenced by addressing the threshold issue of applicable law, considering the international elements and the parties' submissions under the Rome I and Rome II Regulations. It concluded that procedural matters, including interlocutory injunctions, are governed by Irish procedural law (lex fori), and that the applicable substantive law question should not be definitively decided at interlocutory stage but rather treated as part of the fair issue to be tried assessment. The court found a strong arguable case that Irish law governed the contracts of the personal defendants despite their foreign assignments. Regarding Centralis, the court accepted Company A's argument that the claim was primarily to protect property rights (confidential information and goodwill) rather than unfair competition, supporting the application of Irish law.
The court then analysed the nature of springboard injunctions, emphasizing their limited purpose to neutralize an unlawful head start without restraining competition per se. It underscored the requirement for a strong arguable case given the interlocutory injunction's potential to substantially resolve the dispute before trial.
On the facts, the court found credible evidence supporting Company A's contention that certain personal defendants engaged in unlawful acts while still employed, including soliciting customers, downloading confidential information, and preparing documents facilitating the transfer of business to Centralis. It distinguished between lawful preparatory steps and unlawful conduct, concluding that the evidence, if accepted at trial, would support a breach of duty by some personal defendants and corresponding liability for Centralis. The court did not find sufficient evidence against one personal defendant to warrant injunction relief.
Regarding damages, the court held that damages would not be an adequate remedy for Company A due to the irremediable nature of the loss of property rights and the practical difficulty of undoing the head start. Similarly, damages would not fully compensate defendants if injunctions were wrongly granted. The court weighed the balance of convenience, considering the impact on Centralis's business but noting the limited duration of the injunction proposed.
In defining the scope of the injunction, the court applied jurisprudence limiting injunctions to what is reasonably necessary to offset unlawful advantage, rejecting overly broad restraints. It held that injunctions should cover solicitation of customers as of a specified date, use of confidential information defined with precision, and return of such information, but declined to restrain solicitation of employees given the likelihood that any improper solicitation had already occurred. The court set the injunction duration to six months from the date of undertakings given by the defendants, ensuring proportionality.
Finally, the court found that the definition of confidential information must be precise to avoid vagueness and that some information, such as client names, was not confidential, while commercial terms were. It indicated a need for further submissions on the schedule of confidential information subject to the injunction.
Holding and Implications
The court's final decision is that Company A is entitled to an interlocutory springboard injunction against certain personal defendants and Centralis, restraining them from:
- Soliciting customers of Company A as of August 2010, with customers to be specified in a schedule;
- Concluding business with those customers where solicitation has occurred;
- Using confidential information, to be precisely defined in a schedule;
- Returning confidential information as per the agreed or ordered schedule.
The injunction is to last until the earlier of the trial determination or 20 March 2012. One personal defendant is released from undertakings and not subject to injunction due to insufficient evidence. The court emphasises the importance of securing an early trial date given the injunction's onerous nature and the reputational issues involved.
IMPLICATIONS: The order protects Company A's property rights during the interlocutory period without imposing an unlawful restraint on competition. It establishes that springboard injunctions require a strong arguable case and must be narrowly tailored in scope and duration. No new legal precedent is set, but the judgment clarifies the application of existing principles in a complex international context involving multiple jurisdictions and parties.
