The bottom line
#The Environment and Land Court allowed a widow to join an eviction case as a defendant because her land claim was too connected to ignore.
What this practically means
#Executive summary
#Key legal issues
#Whether the 1st Applicant should be joined as a party to the proceedings
The 1st Applicant's presence is necessary for the effectual and complete adjudication of the dispute; she was granted leave to appear as a Defendant
The 7th Defendant derives his claim to the suit property from the 1st Applicant, who purchased the land from the Plaintiff's father before selling it to the 7th Defendant. The Plaintiff seeks eviction and permanent injunction against the 7th Defendant, substantive orders that may prejudice the 7th Defendant if the 1st Applicant is not joined. Joinder also prevents multiplicity of suits since the 7th Defendant would otherwise seek recourse against her.
Locus standi of the 1st Applicant as contended by the Respondent
The Respondent's objection on locus standi did not prevent the joinder, since her interest in the land was intertwined with the dispute
The Respondent argued the 1st Applicant had no locus standi as she was not a party and the land did not form part of her late husband's estate. The court nevertheless found the respective claims intertwined from a similar set of facts, involving a series of sale agreements between 1992 and 2011, which the court had not yet adjudicated upon, making her presence necessary.
