Mary Kiarie v Kenneth Mwangi Kiarie
The bottom line
#Kenya's Court of Appeal refused to excuse a 13–15 month delay in filing an appeal, ruling that even a strong appeal cannot cure unexplained delay.
What this practically means
#Executive summary
#Key legal issues
#Whether the reasons advanced (counsel's maternity leave and financial constraints) sufficiently explained the approximately thirteen to fifteen month delay
The explanation was general and insufficient; no evidence showed when the applicant became aware of the ruling or what steps she took thereafter
The court accepted that Rule 4 confers a wide discretion, but held that inordinate delay requires a plausible and well-supported explanation. Attribution to counsel's leave and financial hardship did not excuse the entire period, because a litigant must remain vigilant over the progress of their case, and finality in litigation weighs heavily against unexplained delay.
Whether the arguability of the intended appeal could outweigh the delay
The draft grounds were not frivolous and might warrant consideration on appeal, but the prolonged and unexplained delay overrode arguability
The court identified two arguable grounds in the draft memorandum: the threshold for review including sufficient cause, and the period of dependency. It nonetheless held that where the delay is prolonged and unexplained, arguability alone cannot persuade the court to exercise its discretion in the applicant's favour.

#- A litigant bears a duty of vigilance to follow up on the progress of their case and cannot rely wholly on counsel's inaction

- Arguability of an intended appeal cannot cure an inordinate and unexplained delay
