“The statement of facts on the evidence before me was a package deal: both parties negotiated and agreed its terms in an endeavour to secure the more expeditious ... and ... advantageous determination of the arbitration. Each party agreed the facts ... in consideration of the like agreement by the other party and, as I see it (for I see nothing to indicate the contrary), intended it to be legally binding. The agreement accordingly does constitute a binding contract. But since it is a contract intended only to be a tool in the conduct and determination of the existing arbitration, it is a contract of a special character. It is a contract which can be enforced or given effect to only in the arbitration, and it seems to me on principle and as a matter of common sense that the very nature of the contract requires as a special incident of such contract that the arbitrator should be entitled either to enforce it or to release the parties from it as the demands of justice require.”
“that there should be finality in litigation and that a party should not be twice vexed in the same matter”. (4) It is the first of these aspects which has been applied in wider circumstances in what has become known as the rule in Henderson v Henderson (1843) 3 Hare 100 in which Sir James Wigram V-C said at pp114-115: “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 6 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.”
“while ... the doctrine of res judicata in all its branches may properly be regarded as a rule of substantive law, applicable in all save exceptional circumstances, the doctrine now under consideration [i.e. the rule in Henderson’s case] can be no more than a procedural rule based on the need to protect the process of the court from abuse and the defendant from oppression.”
“... Henderson v Henderson abuse of process, as now understood, although separate and distinct from cause of action estoppel and issue estoppel, has much in common with them. The underlying public interest is the same: that there should be finality in litigation and that a party should not be twice vexed in the same matter. This public interest is reinforced by the current emphasis on efficiency and economy in the conduct of litigation, in the interests of the parties and the public as a whole. The bringing of a claim or the raising of a defence in later proceedings may, without more, amount to abuse if the court is satisfied (the onus being on the party alleging abuse) that the claim or defence should have been raised in the earlier proceedings if it was to be raised at all. I would not accept that it is necessary, before abuse may be found, to identify any additional element such as a collateral attack on a previous decision or some dishonesty, but where those elements are present the later proceedings will be much more obviously abusive, and there will rarely be a finding of abuse unless the later proceeding involves what the court regards as unjust harassment of a party. It is, however, wrong to hold that because a matter could have been raised in earlier proceedings it should have been, so as to render the raising of it in later proceedings necessarily abusive. That is to adopt too dogmatic an approach to what should in my opinion be a broad, merits-based judgment which takes account of the public and private interests involved and also takes account of all the facts of the case, focusing attention on the crucial question whether, in all the circumstances, a party is misusing or abusing the process of the court by seeking to raise before it an issue which could have been raised before.”
“It is one thing to refuse to allow a party to relitigate a question which has already been decided; it is quite another to deny him the opportunity of litigating for the first time a question which has not previously been adjudicated upon. This latter (though not the former) is prima facie a denial of the citizen's right of access to the court conferred by the common law and guaranteed byarticle 6 of the Convention for the Protection of Human Rights and Fundamental Freedoms (1953).”
