The bottom line
#A Kenyan court ruled that someone claiming money from a lawsuit must join as a full defendant, not just an interested party, and cannot file a counter-claim first.
What this practically means
#Executive summary
#Key legal issues
#Whether the applicant qualifies as an interested party
The applicant has a recognizable stake but his claim is substantive, so joinder as an interested party is inappropriate.
Applying the Supreme Court's Muruatetu and Fanikiwa criteria, the court found the applicant has a recognizable stake in the money claimed. However, he seeks specific remedies against the plaintiff and introduces a new and separate cause of action. An interested party's role is limited to protecting an identifiable interest; one who seeks substantive relief must be joined as a party with substantive claims.
In what capacity should the applicant be joined
The applicant should be joined as 2nd defendant, with the plaintiff directed to amend the plaint; the draft response and counter-claim cannot be admitted as filed.
The plaintiff has no claim against the applicant, so he cannot be joined simply to answer a claim; nor can he file a response or counter-claim before being made a party. Since the subject matter directly affects his rights and the defendant has named him in its defence, the effectual and complete adjudication of all questions requires joinder as 2nd defendant, followed by amendment of the plaint.
Jurisdiction of the Environment and Land Court over the suit
Obiter: the suit is essentially a commercial contract claim over money and ought not to have been filed in the Environment and Land Court.
Exercising section 13(2) of the Environment and Land Court Act, the magistrate observed that although the agreements concern land transactions, the reliefs claimed concern money, not any interest in land. The court suggested the plaintiff may withdraw and file the suit in the proper forum, but made no order striking out the suit.
Legal principles established
#- A person seeking substantive relief against a plaintiff cannot be joined merely as an interested party; the proper course is joinder as a defendant.
- A counterclaim is ordinarily a claim brought by a defendant against a plaintiff; a person not sued cannot as of right file a counterclaim.
