Tamoo v Tamoo & 3 others
The bottom line
#A Kenyan court confirmed that once a judgment is quashed, all orders built on it collapse too, and unappealed rulings cannot be reopened.
What this practically means
#Executive summary
#Key legal issues
#Whether substitution/locus standi/abatement issues were open on this appeal
Not open; conclusively determined in the unappealed Ruling of 7th April 2025
The appeal challenged only the Ruling of 13th October 2025. The earlier Ruling of 7th April 2025 had not been appealed or reviewed and had attained finality. A party cannot indirectly invite an appellate court to reopen findings in an unchallenged decision; finality of litigation precludes re-litigation.
Whether setting aside orders of 11th July 2024 was erroneous
No error; orders were founded on a judgment quashed by the High Court and could not remain in force
Once certiorari quashed the underlying judgment, it ceased to exist in law and consequential orders lost legal efficacy. The trial court possessed inherent jurisdiction to correct an apparent illegality and restore legality, without reopening the merits of land ownership, which were collateral to the application.
Ownership of Parcel Cis-mara/Olposimoru/1328 and Mary Ngoiri Tamooh's interest
Collateral; the application sought substitution and setting aside, not declaration of ownership
The impugned application did not seek a declaration of ownership or cancellation of title. Whether the parcel formed part of the deceased's estate did not answer the legal question of whether orders founded on a quashed judgment could lawfully remain in force.
