78 Loan CWS 5223 was entered into in June 1988. Under the loan agreement, CWS was required to make two repayments of principal, each of $42,000, the second of which was due on 28 December 1988. The first payment, due on 28 September, had not been paid on 16 November 1988, due to disputes between CWS and the Johnson Group, when Rural Finance wrote to CWS a letter reminding it that "your second (and final) loan repayment... falls due in December, 1988". The letter then offers an interest rebate in the event of early payment of the December payment. In response to this, CWS made the December payment 13 days early and received a refund of $246.82. On the date of this reminder letter, the investor's right of non-recourse had been lost due to the non-payment of the first principal repayment. The investor, therefore, had lost its immunity from personal liability for the repayment of all of the principal and interest as and when they fell due. It was argued that the mention in this letter of the repayment being a final loan repayment meant that the letter should be construed as an offer to release the investor from the obligation to make any other loan repayments, if the December instalment was paid early. The consequence of this and of the early payment, it was said, is that CWS accepted this offer and was released from any further obligation under the loan agreement. This would include its obligation to make payments from the proceeds of sale of farm produce and presumably entitle the release of the security which it had given.
