Regina v Secretary of State for the Home Department ex parte Momin Ali: CA 1984

The court discussed the applicability of Ladd -v Marshall principles as to the admission of new evidence in public law proceedings. Sir John Donaldson MR said: ‘the decision in Ladd v Marshall [1954] 1 WLR 1489 has as such no place in that context,’ but ‘the principles which underlie issue estoppel and the decision in Ladd v Marshall, namely that there must be finality in litigation, are applicable subject always to the discretion of the Court to depart from them if the wider interests of justice so require.’
and ‘This fresh evidence was clearly available and should have been placed before Webster J. It is not the function of this court, as an appellate court, to retry an originating application on different and better evidence. We are concerned to decide whether the trial judge’s decision was right on the materials available to him, unless the new evidence could not have been made available to him by the exercise of reasonable diligence or there is some other exceptional circumstance which justifies its admission and consideration by this court. That is not this case.’
