There is an author, Charles Stross, who has a pair of books set in the near future where things like corporate audits are done not to evaulate money expenses but corporate ethical behaviors. (Halting State and Rule 34). Fall out from the NEXT mortgage bubble scam I think. Interesting things to read but not like it would ever get enacted. The idea being if corporations are 'people' then they need to behave in a socially acceptable manner.
