Second, the court will assess whether the result of this exercise of discretion is so outrageous
that no reasonable decision maker could have reached it.
If the right matters have been taken into account and the result is not outrageous, the discretion will be
deemed to have been exercised rationally.
Expressly Excluding an Implied Duty of Good Faith
In principle, it is possible to expressly exclude an implied duty of good faith when drafting a contract.
This is a further consequence of the duty's basis in the contracting parties' presumed intentions.
As such, it is open to the parties to modify the scope of the duty by express contractual terms and to
exclude it altogether.
In practice, however, it may be commercially difficult to suggest excluding a duty of good faith at the
outset of a contractual relationship.
It may be more acceptable to expressly identify those obligations that are to be subject to a duty of
good faith, thereby implicitly evidencing the contracting parties' intention for other obligations not to
be, or to state expressly that a good faith duty only arises where expressly specified in the contract.
As regards the Braganza duty, this is now well established and will be presumed to apply in the absence
of very clear and unequivocal language to oust it and ensure that a contractual discretion is treated as
an absolute contractual right.
Further, in certain factual circumstances even clear language may not be enough. For example, in recent
cases concerning employment and consultancy contracts purporting to provide employers with absolute
discretion whether to award bonuses, the courts have consistently held that such wording did not in fact
provide an absolute discretion, but rather one subject to the Braganza duty.
A party may, in certain circumstances, want to consider including wording to specify the extent to which
any contractual rights are discretions, or as to exactly how any discretions are to be exercised, e.g., by
outlining examples of conduct that will fall in and out of scope, in defined circumstances.
Additional Obligations a Duty of Good Faith May Impose
There is no single definition of good faith, or universally applicable minimum standards that a duty of
good faith entails.
To the contrary, in Compound Photonics Group, which concerned express good faith provisions but
nonetheless provides guidance relevant to an implied duty of good faith, the court warned against a
formulaic approach that may detract from examination and interpretation of the context in which a
specific good faith provision exists.
Instead, courts should try to identify the shared intention of the parties from the express and implied
contractual terms, applying ordinary principles of construction.
As such, any analysis of what additional obligations may be imposed by a duty of good faith, whether
express or implied, is necessarily very fact-dependent.
