Greg King's death is a tragic illustration of one of the burdens of the "standard conception" of the lawyer's role, a conception which at least occasionally requires lawyers to defend clients and causes for which neither they nor others have much sympathy - and to bear the psychological costs of doing so.
The conception consists of three principles. The principle of partisanship requires lawyers to give complete priority to their client's interests. The principle of neutrality says that lawyers cannot pick and choose their clients - other than for reasons such as expertise and workload - and cannot calibrate their efforts according to their own view of the client's cause. Whether clients have legal rights - to plead provocation, for instance - is up to the legislature and the courts, not lawyers. The third principle, non-accountability, is a consequence of the first two: if lawyers must give priority to the interests of clients they do not choose and if they cannot calibrate their efforts according to their own views of those clients or their causes, then they should not be held accountable for the clients or the cause.
The conception does not require or allow lawyers to pursue unlawful advantages for their clients but the law often allows citizens to pursue interests that seem immoral. Should someone who acknowledges that they have savagely killed a young woman be allowed to claim that they were provoked by her wish to end their relationship? Many of us thought no, but when Clayton Weatherston was on trial the law said yes, and so the standard conception required his lawyers to put the defence.
It is easy to see how the conception imposes significant ethical and psychological burdens on lawyers. We all tolerate things we wish were otherwise. Lawyers may be required to zealously bring them about. Of course, the principle of nonaccountability says that lawyers should not be held accountable for the interests the legal system allows clients to pursue but Greg King shows that even lawyers occasionally find it hard to draw this line.
