Supreme Court Gives Guidance On Modular Trials


Modular trials can be a feature of litigation in Ireland before the Commercial List of the High Court. Numerous authorities have set down the rationale for imposing modular trials and have determined the test to be applied when considering whether a particular case is appropriate for or susceptible to modular trials. However, the Supreme Court recently issued its views on the holding of modular trials in the context of an appeal from a Commercial Court decision of Judge Charleton in Weavering Macro Fixed Income Fund Ltd v PNC Global Inv Servicing (Europe) Ltd.1

In that case, the Supreme Court observed that:

"this Court should only intervene if there is demonstrated a degree of irremediable prejudice created by the relevant case management directions such as could not reasonably be expected be remedied by the trial judge (or at least where the chances of that happening were small) and where therefore, unusually, the safer course of action would be for this Court to intervene immediately to alter the case management directions."3

It further noted its decision in PJ Carroll & Co v...
