Working as a contractor in the UK, most contracts stipulate you have Professional Indemnity insurance, which is for exactly this. I doubt anyone has actually made a claim for it though, the amount of other people I've worked with (who are also contractors earning £500+/day) who I wouldn't trust to even watch my laptop is atrocious.

AFAIK, this only really covers gross negligence or outright sabotage. I don't recon anyone trying to pin bad business decisions on their devs are likely to succeed in court.
