The correct answer is (a) Lord Develin.
Lord Develin was a British judge who served on the Judicial Committee of the Privy Council from 1956 to 1962. He is best known for his decision in the case of United Dominions Trust Ltd v Kirkwood, in which he held that “redemption is the heart of mortgage”. This means that the right of the mortgagor (the borrower) to redeem the mortgage (repay the loan) is fundamental to the mortgage contract.
Lord Davey was a British judge who served on the Judicial Committee of the Privy Council from 1887 to 1909. He is best known for his decision in the case of In re Hallett’s Estate, in which he held that a mortgagee (the lender) is entitled to the proceeds of sale of the mortgaged property if the mortgagor defaults on the loan.
Lord Haisburry was a British judge who served on the Judicial Committee of the Privy Council from 1913 to 1922. He is best known for his decision in the case of Re Ames, in which he held that a mortgagee is not entitled to the proceeds of sale of the mortgaged property if the mortgagor has paid off the loan in full.
In conclusion, the correct answer is (a) Lord Develin.
