Dispute Resolution analysis: This case concerned the court’s power to grant an injunction to restrain a litigant from sending abusive communications to an opposing party’s legal team. The High Court dismissed the application, stating that there was no ‘sound jurisdictional basis’ for such relief. The Court of Appeal held this was wrong: the court does have inherent jurisdiction at common law to protect the integrity of its own proceedings. However, the court agreed that refusal of the injunction was appropriate, as there was no ongoing risk and other discretionary factors weighed against relief. The judgment provides guidance for practitioners considering how to address disruptive litigation conduct. It clarifies the scope of the court’s inherent jurisdiction where behaviour poses a serious risk to the administration of justice. Where the conduct falls short of contempt, practitioners seeking such injunctions must also consider the impact of Article 10 ECHR, section 12 HRA, and litigation immunity. The case further highlights appropriate procedural routes and key discretionary factors relevant to injunctive relief. Written by Sarah Ellington, partner at Watson Farley & Williams LLP.
