Suppose that Sam Scientist has just invented some technology with potential for great commercial value. Lacking the resources to develop the technology, she approaches BigCorp. It's in the best interest of both Sam and BigCorp to make a deal.
Sam is an expert in this technical field but has very little expertise in evaluating attorneys. Meanwhile, BigCorp has many attorneys who are specialized in this particular area of tech. Even though no one will be negotiating in bad faith, everyone understands that it's important for Sam to have a good lawyer for this process.
Would it be ethical for a lawyer employed by BigCorp to recommend someone to represent Sam in her negotiation with BigCorp? Should Sam accept such a recommendation if one were offered?
