Today I saw another way to make it clear that you want a party to waive the implied duty of good faith:
Shipper, at its sole discretion and not subject to a reasonableness standard, may determine whether the goods may be salvaged, and if salvageable, the value of such salvage.
For reasons I explain in MSCD and in this 2011 article, I’m not a fan of waiving the implied duty of good faith, although it’s an option available in some jurisdictions. Saying And we can be as unreasonable as we wanna be! be isn’t a good look, particularly if what’s at stake is an issue you could address directly.
I share your distaste for attempted waivers of the implied duty of good faith. My favoured workaround, if possible, is to draft the affected subject matter out of the contract: ‘The Shipper is not required to salvage the goods, to determine whether the goods are salvageable, to determine the goods’ salvage value, if any, or to share with any person the benefit, if any, of salvage’.
