77 Counsel for Mr McCourt referred only to Renstel Nominees in support of the proposition that the Bank owed a duty of good faith. However, the Bank made no submissions in response to those provided by Mr McCourt on the good faith ground. Accordingly, I do not propose to look beyond Renstel Nominees on the question of whether an obligation of good faith and fair dealing can or should be implied into a commercial facility. An interlocutory application is not, in any event, the proper occasion to explore the controversies surrounding the possible implication of the obligation into commercial contracts, particularly as the search in this instance is only for a prima facie case (and see generally, Seddon NC and Ellinghaus MP, Cheshire and Fifoot's Law of Contract (9th Australian ed, 2008) [10.43] and see also, Paterson JM, 'Limits on a Lender's Right to Repayment on Demand: Construction, Implication and Good Faith?' (1998) 26 Australian Business Law Review 258 for a discussion of whether it is commercially desirable to condition a lender's right to demand repayment by a duty of good faith). I would only add that the reasoning of Byrne J in Renstel Nominees does not go so far as establishing that it is becoming 'increasingly accepted' that on-demand facilities attract an obligation of good faith and fair dealing.
