more than one, was deemed to have admitted that he had no other answer or reply than that to which he had to confine himself, and this is the ratio decidendi of the two cases on which reliance was placed for the respondent.
Thus explained, they in no way derogate from the general principles of law.
It is seen from this citation of authority that, if in any Court of competent jurisdiction a decision is reached, a party is estopped from questioning it in a new legal proceeding. But the principle also extends to any point, whether of assumption or admission, which was in substance the ratio of and fundamental to the decision. The rule on this subject was set forth in the leading case of Henderson v. Henderson (1) by Wigram V.C. as follows -"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." This authority has been frequently referred to and followed, and is settled law.
"I think," said Williams J. in Howlett v. Tarte (2), 'it is quite clear upon the authorities to which our attention has been called, and upon principle, that, if the defendant attempted to put upon the record a plea which was inconsistent with any traversable allegation in the former declaration, there would be an estoppel."
This passage has been accepted expressly over and over again, as, for instance, by Phillimore J. (now Lord Phillimore) in Humphries
