"90. At end of cross-examination, C was asked by counsel for D1 and D2 whether there was any arrangement between the parties other than one for a sale at£1.35 million . C said there was not. Counsel pressed him: if he was not believed on this, then was he sure there was nothing else, no other discussions other than for a sale. C confirmed that the only arrangement with D1 was for a sale."
"[21] In my view the judge was not entitled to find for the claimant on the basis of the third man theory. It is fundamental to our adversarial system of justice that the parties should clearly identify the issues that arise in the litigation, so that each has the opportunity of responding to the points made by the other. The function of the judge is to adjudicate on those issues alone. The parties may have their own reasons for limiting the issues or presenting them in a certain way. The judge can invite, and even encourage, the parties to recast or modify the issues. But if they refuse to do so, the judge must respect that decision. One consequence of this may be that the judge is compelled to reject a claim on the basis on which it is advanced, although he or she is of the opinion that it would have succeeded if it had been advanced on a different basis. Such an outcome may be unattractive, but any other approach leads to uncertainty and potentially real unfairness."
"[242] In the adversarial system of litigation in this country, the task of the courts is to do justice between the parties in relation to the way in which they have framed and prosecuted their respective cases, rather than to carry out some wider inquisitorial function as a searcher after truth."
"[7] Apart from certain basic facts, almost everything else was disputed. Documents were alleged to have been forged and fabricated, and witnesses to have given false evidence, and the Judge indeed found much of the oral evidence (on both sides) unreliable. In those circumstances there were few secure footholds for him as he picked his way through the allegations. Such a case poses particular difficulties for a trial judge, and requires careful findings of fact, firmly set in the context of what each party alleges, and which of the allegations have either been admitted or proved to the requisite standard. Regrettably, as will appear, this is not what happened here."
"[35] This is not therefore a case, as sometimes happens, where one or other of the parties seeks to run a different case at trial from that pleaded. That itself is unsatisfactory and can cause difficulties, as has been said recently by this Court more than once: see UK Learning Academy Ltd v Secretary of State for Education[2020] EWCA Civ 370 at [47] per David Richards LJ where he said that statements of case play a critical role in civil litigation which should not be diminished, and Dhillon v Barclays Bank plc[2020] EWCA Civ 619 at [19] per Coulson LJ where he said that it was too often the case that the pleadings become forgotten as time goes on and the trial becomes something of a free-for-all. As both judges say, the reason why it is important for a party who wants to run a particular case to plead it is so that the parties can know the issues which need to be addressed in evidence and submissions, and the Court can know what issues it is being asked to decide. That is not to encourage the taking of purely technical pleading points, and a trial judge can always permit a departure from a pleaded case where it is just to do so (although even in such a case it is good practice for the pleading to be amended); in practice the other party often, sensibly, does not take the point, but in any case where such a departure might cause prejudice he is entitled to insist on a formal application to amend being made: Loveridge v Healey[2004] EWCA Civ 173 at [23] per Lord Phillips MR."
"[36] The present case however is not one of a party seeking to depart from his pleaded case, but one where the parties addressed in their evidence and submissions the cases that had been pleaded, but the Judge decided the case on a basis that had neither been pleaded nor canvassed before him. In our system of civil litigation that is impermissible, and a misunderstanding of the judge's function which is to try the issues the parties have raised before him. The relevant principles were stated by this Court in Al-Medenni v Mars UK Ltd[2005] EWCA Civ 1041 . There the trial judge had rejected the claimant's pleaded allegation of how she had sustained an accident but nevertheless found the defendant liable on the basis of his own theory of what had happened (referred to as the "third man theory"), which had never formed any part of either party's pleaded case. [ The paragraph then quotes para 21 of Al-Medenni ] [37] In that case the Judge had in fact raised the third man theory with counsel in the course of closing submissions, and there was a "rather faint-hearted" espousal of it by the claimant's counsel, but that was far too late for the claimant to take the point as it had not been explored with any of the witnesses: see at [23]-[24]. Dyson LJ said that the judge, having rejected the claimant's pleaded case, should have dismissed the claim, and by making findings for which the claimant was not contending, had crossed the line which separates adversarial and inquisitorial systems; what he did might have been legitimate in an inquisitorial system but was impermissible in our system: see at [25]. [38] In the present case, the possibility that the Croydon Properties were held on trust for Mr V Sharma does not appear to have been even canvassed by the Judge during the hearing, but, as far as we know, first emerged fully-formed in the Judgment. That, for the reasons given by Dyson LJ in Al-Medenni , was not a course that was open to him. Judges may sometimes think – and may even sometimes be right – that their own theory better fits the facts than that of either party, but if it is wholly outside the scope of the pleaded issues, that is nothing to the point, and to decide a case on a basis that has not been explored in evidence or addressed in submissions is likely to leave at least one, if not both, parties with a profound sense of unfairness."
