#Interference with discretionary decisions on appeal
The appellants established misdirection: the Judge overlooked the supporting affidavit of Anthony Kinyanjui Munyui and the ground on the face of the application regarding a new witness, so interference was warranted.
The Court reiterated the limited grounds for interfering with discretionary decisions. It found the Judge misdirected himself by stating there was no mention of the alleged discovery of a new witness, when the application was grounded on that averment and supported by a further affidavit deponing to the deceased's state of health at the time the Will was made. Since the circumstances of the Will's preparation and the deceased's capacity were central, this misdirection entitled the Court to interfere.
Consistency of the appellants' statements on awareness of the hearing date
The Court agreed with the Judge that the appellants' contradictory claims about awareness of the 14th July 2015 hearing date did not constitute a wrong exercise of discretion.
The application's body said the appellants were aware of the hearing date but the matter was not listed, while the joint supporting affidavit deponed they were unaware of the hearing date and were never served. The Court held these clearly inconsistent statements meant the Judge's finding of laxity and indolence was not a wrong exercise of discretion. However, this did not save the ruling given the misdirection on the review/discovery ground.
Legal principles established
#- The Court of Appeal will not interfere with a discretionary decision unless the judge misdirected himself in law, misapprehended the facts, took into account considerations he should not have, failed to take into account considerations he should have, or the decision is plainly wrong.
- A judgment may be reviewed where a ground of discovery of new evidence is raised on the face of the application and supported by affidavit, even if not deponed in the applicants' own joint affidavit.
