Wainaina v Mucheru & another; Kamau (Applicant)
The bottom line
#A Kenyan court refused to appoint a guardian for an elderly land defendant because no medical evidence proved he could not protect his own interests.
What this practically means
#Executive summary
#Key legal issues
#Jurisdiction to inquire into a party's mental infirmity during a pending suit
The court seized of the suit has jurisdiction to conduct the inquiry under Order 32 rule 15; proceedings need not be initiated under the Mental Health Act
The court held that questions of a party's mental capacity arising during the pendency of a suit may be determined by the court seized of the matter, provided they are relevant to the proceedings. Both parties agreed the court had jurisdiction; the dispute was procedural. Order 32 rule 15 covers persons not adjudged of unsound mind but found on inquiry to be incapable of protecting their interests.
Whether the 1st Defendant was incapable of protecting his interests due to memory lapse
No finding of incapacity could be made absent medical evidence; the application was premature
The applicant merely alleged infirmity and attached only the 1st Defendant's identity card showing his age. The court, relying on Mulla and Indian authority, held that a judicial inquiry is required, that proof of absolute lunacy is unnecessary but medical assistance is a proper precaution, and that old age is not synonymous with mental infirmity. Without a medical report the inquiry could not be completed.
Whether the Applicant should be appointed guardian ad litem
Refused as premature; appointment must await the inquiry
Since the court could not yet find incapacity, the applicant could not yet be appointed guardian ad litem. The court, however, invoked its overriding objective powers to direct a medical examination and production of the 1st Defendant for an inquiry, so the question could be properly determined thereafter.
