The parties were former joint investors in two real estate properties.
The defendant paid the plaintiff $195,000, which the defendant claimed was a full settlement for both properties, while the plaintiff claimed it was only for one.
Three years into the litigation, the defendant brought a motion to amend his statement of defence, withdraw admissions, and add a counterclaim alleging he overpaid the plaintiff.
The court dismissed the motion, finding that the admissions were advertent and that allowing the amendments would fundamentally alter the factual narrative, causing prejudice to the plaintiff that could not be remedied by costs.
