Fair enough!You're asking how it would work across dozens of Civil Law jurisdictions when I'm not even French. I'm not going to attempt to answer that.![]()
I had a colleague who worked on the CISG, and so was into comparative Civil and Common Law contract law. Her view was that there was more overlap on good faith in contracting than is sometimes thought, once common law doctrines that govern pre-contractual negotiations are fully taken into account (eg estoppel, undue influence, unconscientious dealing/"catching bargains", misrepresentation, fiduciary law in some cases, etc).
But as I said it's not something I've ever really tried to get my head around.
