“... first ... that once a cause of action has been held to exist or not to exist, that outcome may not be challenged by either party in subsequent proceedings. This is “cause of action estoppel”

“... 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 on 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.”
“... these various defences are all designed to serve the same purpose: to bring finality to litigation and avoid the oppression of subjecting a defendant unnecessarily to successive actions. While the exact relationship between the principle expounded by Sir James Wigram V-C and the defences of res judicata and cause of action and issue estoppel may be obscure, I am inclined to regard it as primarily an ancillary and salutary principle necessary to protect the integrity of those defences and prevent them from being deliberately or inadvertently circumvented.”
“I can confirm I have processed your request for judgment on this case and it is now with the Master awaiting directions. Once the Master comes back with their response, I will let you know.”
“... an order (or its extension) ... [is] necessary in order (a) to protect litigants from vexatious proceedings against them and/or (b) to protect the finite resources of the Court from vexatious waste.”
“4.1 ... where the party against whom the order is made persists in issuing claims or making applications which are totally without merit, in circumstances where an extended civil restraint order would not be sufficient or appropriate.”
