The Dekagram: 4th August 2025
This week John Schmitt brings you a further reminder that judgments must be adequately reasoned, but that the responsibility for eliciting adequate reasoning rests (at least partly) on the parties’ representatives. It would seem that the Court of Appeal takes the view that not only should litigators be gracious losers, when they do lose they should give the judge not one but two opportunities to get his or her judgment right. Insult to injury, some may feel.
Inadequate Reasoning In Judgments: a Reminder, and a Note of Caution for Litigators
In GLAS SAS (London Branch) v European Topsoho SARL [2025] EWCA Civ 933, the Court of Appeal has given important guidance to practitioners (and judges) about the issue of inadequate reasoning in judgments and the need to address it contemporaneously.
The First Instance Decision
The first instance decision centred on a party that had been added as the fourth defendant (“D4”) in circumstances where certain conditions were imposed on it (regarding transfer of shares and payment into court). D4 challenged the conditions as well as the inadequate judicial reasoning for the imposition of the conditions.
The Dismissing of the Appeal
The Court of Appeal found no reason to set aside the first instance order but did find the judge had erred in failing to provide adequate reasoning. The judge in essence reached a sensible decision but without providing a detailed rationale; it is notable the hearing ran for under half its time estimate and the first instance ex tempore ruling invited parties to understand it “in the context of the discussion during the hearing itself. Elements of the reasoning can be gleaned from that discussion.”
The Guidance for Practitioners and Judges
The Court of Appeal emphasised that the parties, especially the losing party, should be left in no doubt as to why they have won or lost; there is a minimum level of reasoning that is required.
Lady Justice Falk proceeded to give summary advice on the core principles for judicial reasoning for case management decisions, stating that these points should come as no surprise to experienced judges, but they may assist those at earlier stages of their judicial careers:
Comment
It seems likely that the parties at first instance were aware they had been given a sparse, perhaps hurried judgment, and one that would open the door for D4 to argue it was not properly reasoned. The Court of Appeal deprecate the practice of a party challenging a decision in an opportunistic way without first giving the first instance judge (in the immediate aftermath of the judgment) the opportunity to provide fuller detail and to address why the losing party’s arguments were rejected. The hint from the Court of Appeal is that such opportunism could be punished in adverse costs orders at the appeal stage.
The final principle (at (f)) appears to give the first instance judge scope to “perfect” a judgment in a far-reaching way, to include conveying “what the judge intended to say” and “further reasoning” that was in the “judge’s mind but was omitted in error” by means of a post-script. This seems to give a judge an opportunity to provide much more comprehensive reasoning at the point a judgment is being challenged and to do so in written form in order to assist the appeal court. This might seem surprising and a generous further opportunity, but it must also be consistent with the overriding objective.
The tenor of the guidance in the Court of Appeal is to grasp issues with the reasoning of case management decisions at first instance, especially following a seemingly scant judgment, and to plug any gaps in rationale before the matter reaches the appeal stage. This would be to avoid what happened here: the appeal court leaving undisturbed the first instance decision but having to spend a day understanding why it had been made.
As my Maths teacher used to say, “don’t just write the answer: show your working!”.
