It is long settled that a consent judgment or order made by a court to give effect to the compromise of a legal claim by the parties may be set aside, not only on the ground of fraud, but for any other reason which would afford a good ground for setting aside the agreement on which the judgment or order is based, e.g. on the ground of a common mistake, fraudulent misrepresentation or misconception. See Attorney-General v. Tomline (1877) 7 Ch. D. 388, Huddersfield Banking Company Ltd. v. Henry Lister and Son Ltd. (1895-99) All E.R. 868 (C.A.) … It is thus clear that apart from fraud which, if established in any judgment or order, necessarily invalidates the same, a consent judgment or order may be set aside for cogent and sufficient reason which in law would constitute a ground for setting aside the agreement on which such consent judgment or order was based. As Lindley, LJ. put it in Huddersfield-Banking Company Ltd. v. Henry Lister and Son Ltd. (supra) at Page 871:- “A consent order, I agree, is an order, and so long as it stands, it must be treated as such, and so long as it stands I think it is as good an estoppel as any other order. I have not the slightest doubt on that point. But that a consent order can be impeached not only on the ground of fraud but upon any grounds which invalidate the agreement it expresses in more formal way than usual. I also have not the slightest doubt.”
