Knightsbridge Estates Trust Ltd v Byrne

Facts

• Knightsbridge Estates Trust Ltd (a property company) borrowed money from Byrne, secured by mortgage of their freehold properties
• The mortgage provided that principal would be repaid by half-yearly instalments over 40 years
• The company sought to redeem the mortgage early, arguing that the 40-year term was an unreasonable clog on the equity of redemption

Issue

1. Whether a 40-year repayment term in a company mortgage/debenture constitutes an unreasonable clog on the equity of redemption, rendering it void or unenforceable.

Held

• Sir Wilfrid Greene MR held that the 40-year term was valid. The equitable doctrine that protects mortgagors from oppressive clogs on redemption was developed to protect individual landowners from unconscionable bargains. A company borrowing commercially at arm's length is in a fundamentally different position. The company freely agreed to the term as a commercial bargain and could not escape it by invoking equitable principles designed for a different context.

Ratio Decidendi

The doctrine of clog on the equity of redemption has limited application to companies. A company is an artificial person acting through directors in a commercial capacity. When a company freely negotiates borrowing terms at arm's length, the court will not interfere with the bargain merely because the repayment period is long. The rationale for protecting vulnerable individual mortgagors does not apply to sophisticated commercial borrowers.
