If Equity can develop new orders when necessary, can it develop anti-SLAPP orders? Part 2: SLAPPs, abuse of process, and anti-SLAPP injunctions
1. Introduction: strategic lawsuits against public participation
In an earlier post on this blog, I argued that Equity can develop new orders and injunctions when necessary, and that there was space for it to develop a new order or injunction to prevent strategic lawsuits against public participation (anti-SLAPP orders). There have been several subsequent developments which compel me to revisit that post and make good on my promise in it to return to the topic.
First, the jurisdiction to develop new equitable injunctions has continued to evolve. In Pepper Finance Corporation (Ireland) DAC v Persons Unknown [2023] IESC 21 (31 July 2023), the Supreme Court held that, in exceptional cases, proceedings may be issued against persons unknown. Once such proceedings were properly issued, Hogan J (O’Donnell CJ, and Dunne, Charleton and O’Malley JJ concurring) assumed that an injunction could be ordered against persons unknown, and he proceeded directly to a consideration of the procedural steps to enforce it by means of the contempt jurisdiction, untroubled by any discussion of the basis of this heretofore unspotted injunction. The jurisdiction to award injunctions against persons unknown had been considered by the Court of Appeal of England and Wales in Canada Goose UK Retail Ltd v Persons Unknown [2020] EWCA Civ 303 (05 March 2020), which Hogan J cited with approval in Pepper Finance, so it may be that he felt that it was not necessary to revisit the question.…
