[2023] EWHC 2885 (TCC)
Henderson v Henderson principle: A party must bring their whole case against another party in a single action.
Henderson v Henderson (1843) 3 Hare 100
Johnson v Gore Wood principle: Abuse of process requires a broad, merits-based judgment considering public and private interests and whether a party is misusing court process.
Johnson v Gore Wood [2000] UKHL 65
Aldi guidelines: In ongoing litigation, a party with potential connected claims must raise them with the court. Breach of these guidelines increases the risk of the second action being struck out as abuse of process.
Aldi Stores Ltd v WSP Group PLC [2007] EWCA Civ 1260
Denton v TH White: When considering striking out applications, especially with Aldi guideline breaches, consider the seriousness of the breach, reasons for it, and all circumstances (including consequences of sanction).
Denton v TH White Limited [2014] EWCA Civ 906
Appeal dismissed.
The Court of Appeal held that while MW breached the Aldi guidelines, the judge at first instance correctly applied a broad merits-based assessment. The absence of significant overlap between the Main Action and the new claims, the hypothetical possibility of the misrepresentation claims being dealt with separately even if raised earlier, and the existence of similar claims related to other projects meant that the new proceedings did not constitute an abuse of process.
