Groongal Pastoral Co Ltd (in liq) v Falkiner

The case of *Groongal Pastoral Co Ltd (in liq) v Falkiner* involved an appeal to the High Court of Australia from the Supreme Court of New South Wales. The dispute arose from a memorandum of mortgage executed by Ralph Sadlier Falkiner in favour of Groongal Pastoral Co Ltd (in liquidation). The mortgagor covenanted to repay a principal sum and interest, with the interest payments to be made "free from exchange, income tax and all other deductions." The mortgagee subsequently brought an action seeking to recover income tax it had paid in respect of the interest received from the mortgagor, arguing that the covenant obliged the mortgagor to indemnify it against such tax. A further issue arose from the subsequent discharge of the mortgage.

The legal issues before the High Court were twofold: first, the proper construction of the mortgage covenant regarding the payment of interest "free from income tax and all other deductions"; and second, the legal effect of a registered discharge of the mortgage on the mortgagor's personal obligations. The mortgagee contended that the covenant required the mortgagor to ensure the mortgagee received the full stipulated interest rate, free from any reduction due to income tax, and that the discharge of the mortgage only released the land from the encumbrance, not the personal liability of the mortgagor. The mortgagor argued that the discharge, being a registered instrument under the *Real Property Act 1900* (NSW), operated to extinguish his personal obligations as well.

The High Court, affirming the majority decision of the Full Court of New South Wales, held that the covenant to pay interest "free from exchange, income tax and all other deductions" meant that the mortgagor was bound to indemnify the mortgagee, if necessary by reimbursement, against any diminution of the interest caused by income tax, so as to leave the specified interest rate clear in the hands of the mortgagee. However, the Court found that the registered discharge of the mortgage, which was in the form of a receipt for the full mortgage debt "being in full satisfaction and discharge of the within obligation," had the effect of a deed by virtue of its registration under the *Real Property Act 1900* (NSW). Consequently, the Court concluded that this discharge operated by its terms to release the mortgagor from his personal obligation, in addition to releasing the land from the encumbrance.

Accordingly, the High Court dismissed the appeal, upholding the decision of the Supreme Court of New South Wales that the mortgagor's personal liability had been discharged by the registered mortgage discharge.
