Well, those were the legal principles engaged. What the court did was enunciate.... For example, solicitor-client privilege is well-known and has been accepted for many years as a principle of fundamental justice. But this concept that the state must not undermine a lawyer's commitment to his or her client's cause is a newly expressed principle of fundamental justice, which ties in the independence of the bar and the lawyer's duty to the client and that sort of thing. That was the underlying principle.
