Gordon Smith writes:
In Good Faith and Fair Dealing as an Underenforced Legal Norm, Paul MacMahon of the London School of Economics explores the divide between "the rhetoric of good faith and fair dealing and the reality of judicial enforcement." ... This is a well-researched, well-written, thought-provoking article, and I recommend it highly.
I agree and encourage you to check out both Gordon's excellent summary and the paper itself.
