Those who are responsible for choosing the recipient of the Isaac Ray Award have rung the bell again. They invited another lawyer; and the results are on the high level established by the first three holders of the Award.

Weihofen discusses the M'Naghten and the New Hampshire Rule (the Ray Rule) in reference to a complicated case, and this device illuminates the true subtlety of the question facing a jurist or a physician. He is willing to go along with the abandonment of M'Naghten and the acceptance of the 'product' test. But in a valuable chapter on The Search for Certainty he argues forcefully against overestimating the impact of verbal formulae, citing in this connection the preliminary report of the University of Chicago Jury Project. The facts of the Durham case were presented to a number of mock juries drawn from the Chicago Municipal Court Jury Pool. Many factors were demonstrated to affect the outcome.
