Ethics

Via Leiter's Law School Reports, here's a story about a university challenging a decision by a university-based law clinic to represent unionizing workers at another university.  Here in the US we've had some controversies along those lines but I haven't followed them closely.  It's an interesting scenario to ponder from an ethics point of view.  We have plenty of rules designed to protect the independence of the lawyer, and in particular rules to protect the attorney-client relationship from interference from the non-clients who are paying the lawyer.  But the university setting makes a difference, doesn't it?  Is it clear in the US that the clinic itself, as opposed to the university administration, decides what kind of cases the clinic will handle? Who decides?
