First, the essence of the action is fraud. As in all actions based on fraud, particulars of the fraud claimed must be exactly given and the allegations must be established by the strict proof which such a charge requires.
Secondly, it must be shown, by the party asserting that a judgment was procured by fraud, that there has been a new discovery of something material, in the sense that fresh facts have been found which, by themselves or in combination with previously known facts, would provide a reason for
setting aside the judgment. ...
Thirdly, mere suspicion of fraud, raised by fresh facts later discovered, will not be sufficient to secure relief. The claimant must establish that the new facts are so evidenced and so material that it is reasonably probable that the action will succeed. This rule is founded squarely in the public interest in finality of public litigation and in upholding judgments duly entered at the termination of proceedings in the courts.
Fourthly, although perjury by the successful party or a witness or witnesses may, if later discovered, warrant the setting aside of a judgment on
the ground that it was procured by fraud, and although there may be exceptional cases where such proof of perjury could suffice, without more, to warrant relief of this kind, the mere allegation, or even the proof, of perjury will not normally be sufficient to attract such drastic and exceptional relief as the setting aside of a judgment. The other requirements must be fulfilled. ...
Fifthly, it must be shown by admissible evidence that the successful party was responsible for the fraud which taints the judgment under challenge. The evidence in support of the charge ought to be extrinsic. It is not sufficient to show that an agent of the successful party was convicted of giving perjured evidence in the former proceeding, the result of which it is sought to impeach. It must be shown that the agent, in so acting, was in concert with the party who derived the benefit of the judgment.
Sixthly, the burden of establishing the components necessary to warrant the drastic step of setting aside a judgment, allegedly affected by fraud or other relevant taint, lies on the party impugning the judgment. It is for that party to establish the fraud and to do so clearly. In summary, he or she must establish that the case is based on newly discovered facts; that the facts are material and such as to make it reasonably probable that the case will succeed; that they go beyond mere allegations of perjury on the part of witnesses at the trial; and that the opposing party who took advantage of the judgment is shown, by admissible evidence, to have been responsible for the fraud in such a way as to render it inequitable that such party should take the benefit of the judgment.
