Case law



IPPT20231030, UPC CFI, CD Munich, Nanostring v Harvard

Order to provide security for legal costs and other expenses pursuant to Rule 158.1 RoP to the amount of EUR 300,000. Additional (procedural) burden and uncertainty on the party seeking to enforce a UPC (cost) judgement in the UK compared to other (EU) jurisdictions. This is a factor that weighs in favour of ordering a security. Legitimate concern that the Claimant will not have adequate financial means to cover the legal expenses that it may be liable for. Submitted that the injunction ordered in other case by Munch Local Division would be “existence-threatening”. Claimant has not provided any information as to its own, independent, financial position nor has it pointed at any of its own assets that could be suitable for redress should it be liable for any legal costs. Instead, it relies solely on the cash position of its group of companies. The group, however, in its own words, has never been profitable and therefore relies on money from investors.


IPPT20231020, UPC CFI, LD Helsinki, AIM Sport Vision v Supponor

No security for costs (Rule 158 RoP). No sufficient evidence of  risk of insolvency and evidence indicates that the Applicant will have the financial means to cover any potential legal costs. Not appropriate for the Court of First Instance to order security for the costs of potential future proceedings in the Court of Appeal.


IPPT20230929, UPC CFI, LD Munich, Edwards Lifesciences v Meril

No security for the legal costs and other expenses (Rule 158 RoP) ordered. It requires a showing that the financial circumstances of the other party give rise to fears that any claim for reimbursement of costs cannot be served or that, despite sufficient financial resources, enforcement of a decision on costs appears to be impossible or fraught with particular difficulties. Such a request cannot be made the subject of Preliminary objection (Rule 19 RoP). The possible subjects of a Preliminary objection are exhaustively listed in Rule 19(1) RoP. Motions pursuant to Rule 158(1) RoP are not listed.
