It is only in relatively recent times that the courts have endeavoured to impose some coherent scheme on these disparate areas of law. The starting point is the statement of principle of Wigram V-C in HENDERSON v. HENDERSON [1843] 3 Hare 100, 115. This was an action by the former business partner of a deceased for an account of sums due to him by the estate. There had previously been similar proceedings between the same parties in Newfoundland in which an account had been ordered and taken, and judgment given for sums found due to the estate. The personal representative and the next of kin applied for an injunction to restrain the proceedings, raising what would now be called cause of action estoppel. The issue was whether the partner could reopen the matter in England by proving transactions not before the Newfoundland court when it took its own account. The Vice-Chancellor said: S/N nd6oq8B3sEyZ4s4xbFUJRg 10 | P a g e "In trying this question I believe I state the rule of the Court correctly when I say that, where a given matter becomes the subject of litigation in, and of adjudication by a Court of competent jurisdiction, the Court requires the parties to that litigation to bring forward their whole case, and will not (except under special circumstances) permit. the same parties to open the same subject of litigation in respect of matter which might have been brought forward as part of the subject in contest, but which was not brought forward, only because they have, from negligence, inadvertence, or even accident, omitted part of their case. The plea of res judicata applies, except in special cases, not only to points upon which the Court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation, and which the parties, exercising reasonable diligence, might have brought forward at the time... Now, undoubtedly the whole of the case made by this bill might have been adjudicated upon in the suit in Newfoundland, for it was of the very substance of the case there, and prima facie, therefore, the whole is settled. The question then is whether the special circumstances appearing upon the face of this bill are sufficient to take the case out of the operation of the general rule." [83] There are a few points to be noted which are as follows: i. The doctrine of merger concerns a matter that has been decided upon and culminates in a court judgment raises an effective defence called "estoppel". ii. the Court requires the parties to that litigation to bring forward their whole case, and will not (except under special circumstances) permit the same parties to open the same subject of litigation in respect of matter which might have been brought forward as part of the subject in contest, but which was not brought forward, only because they have, from negligence, inadvertence, or even accident, omitted part of their case. iii. The plea of res judicata applies, except in special cases, not only to points upon which the Court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation, and which the parties, exercising reasonable diligence, might have brought forward at the time. iv. This doctrine arises from the same facts and the same cause of action. [84] However, it must be distinguished from a matter arising from the same facts but different cause of action is NOT caught by this Doctrine. It is only when there are not only the same set of facts but also the same set of cause of actions, then the suit is caught by the Doctrine of Merger. S/N nd6oq8B3sEyZ4s4xbFUJRg 11 | P a g e [85] The House of Lords in ARNOLD v. NATIONAL WESTMINSTER BANK PLC[1991] 2 AC 93. The question at issue in that case was whether in operating a rent review clause under a lease, the tenants were bound by the construction given to the very same clause by Justice Walton in earlier litigation between the same parties over the previous rent review. The Court of Appeal had subsequently, in other cases, cast doubt on Justice Walton's construction, and the House approached the matter on the footing that the law (or perhaps, strictly speaking, the perception of the law) had changed since the earlier litigation. Lord Keith of Kinkel began his analysis by restating the classic distinction between cause of action estoppel and issue estoppel: "Cause of action estoppel arises where the cause of action in the later proceedings is identical to that in the earlier proceedings, the latter having been between the same parties or their privies and having involved the same subject matter. In such a case the bar is absolute in relation to all points decided unless fraud or collusion is alleged, such as to justify setting aside the earlier judgment. The discovery of new factual matter which could not have been found out by reasonable diligence for use in the earlier proceedings does not, according to the law of England, permit the latter to be re-opened.(104D-E) Issue estoppel may arise where a particular issue forming a necessary ingredient in a cause of action has been litigated and decided and in subsequent proceedings between the same parties involving a different cause of action to which the same issue is relevant one of the parties seeks to re-open that issue."(105E) [86] The Federal Court in TINDAK MURNI SDN BHD v. JUANG SETIA SDN BHD & ANOTHER APPEAL [2020] 4 CLJ 301 has this to say, inter alia, [87] The other submission that the doctrine of merger prevents an arbitration clause from 'severing' a judgment because the cause of action has merged in the judgment and the judgment acquires a higher status (per Lord Sumption in VIRGIN ATLANTIC AIRWAYS LIMITED (RESPONDENT) v. ZODIAC SEATS UK LIMITED [2013] UKSC is similarly inapplicable in the instant appeal. A cursory reading of the case discloses that it is a judgment relating to the adjudication of patents which went through a full trial in the English courts. The appeal in the Supreme Court of the United Kingdom relates primarily to the problems arising from the system of parallel jurisdiction for determining the validity of European patents. Its relationship to the instant appeals is completely obscure. A passage mid-way in the judgment of Lord Sumption appears to have been selected and randomly cited. S/N nd6oq8B3sEyZ4s4xbFUJRg 12 | P a g e At para. 16 of the judgment, the issue in the appeal is set out, namely that an order of the Court of Appeal upholding the validity of the patent and directing an enquiry as to damages may only be varied by way of an appeal. However, no further avenues of appeal were open. The issue before the court was whether one of the parties was entitled to contend in the inquiry that there were no damages because the patent had been retrospectively amended so as to remove the claims held to have been infringed. This in turn depended upon whether the Court of Appeal was correct to state that its order declaring the patent to be valid continued to bind the parties per rem judicatum notwithstanding that the patent was later amended on the basis that it was not valid in the relevant aspects. It is in this context that Lord Sumption made a statement on the doctrine of merger, in relation to res judicata. He explained the doctrine of merger as treating a cause of action as extinguished, once a judgment has been given upon it, and the claimant's sole right as being a right upon the judgment. He also stated that this principle is a substantive rule about the legal effect of an English judgment which is regarded as of a higher nature and therefore as superseding the underlying cause of action, premised upon a decision dating back to 1844 (KING v. HOARE [1844] 13 MW). [88] Reverting to the issue of advocacy, written or oral, it bears reiterating that if a passage in a judgment is sought to be relied upon, it is incumbent upon counsel to set out and explain:
