Issue estoppel and res judicata
23 The defendant referred me to Henderson v Henderson [1843-60] All ER 378, Wigram VC said at p 382:
"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 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 pleas 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."
24 A more often quoted case on the topics of res judicata and issue estoppel is that of the High Court in Port Melbourne Authority v Anshun Pty Limited (1981) 147 CLR 589, where Gibbs CJ, Mason and Aickin JJ said:
"The distinction between res judicata (in England called 'cause of action estoppel') and issue estoppel was expressed by Dixon J in Blair v Curran (20) in these terms: "in the first the very right or cause of action claimed or put in suit has in the former proceedings passed into judgment, so that it is merged and has no longer an independent existence, while in the second, for the purpose of some other claim or cause of action, a state of fact or law is alleged or denied the existence of which is a matter necessarily decided by the prior judgment, decree or order.'
The distinction was restated by Fullagar J in his dissenting judgment in Jackson v Goldsmith (21). His Honour expressed the rule as to res judicata by saying: 'where an action has been brought and judgment has been entered in that action, no other proceedings can thereafter be maintained on the same cause of action. This rule is not, to my mind, correctly classified under the heading of estoppel at all. It is a broad rule of public policy based on the principles expressed in the maxims "interest reipublicae ut sit finis litium" and "nemo debet bis vexari pro eadem causa".' His Honour went on to discuss issue estoppel, citing the comment of Dixon J in Blair v Curran (22 ): 'A judicial determination directly involving an issue of fact or of law disposes once for all of the issue, so that it cannot afterwards be raised between the same parties or their privies.'
