Question

I'm not really good at business law

the question is
"You are advising a client who is the managing partner of a 6 person partnership engaged in a property development in NSW. The partnership is considering doing something which while legal, may not be morally correct (unethical). Write an essay setting out the theoretical framework you would use to discuss with the client what they should do in such a situation.

(My Question is what Kind of framework is needed?)

In your answer, you are to discuss the importance of ethical decision making and give two examples of relevant corporate ethical scandals that have occurred over the past decade in Australia.

(give me some relevant examples)
