(Original Review, 1980-11-28)
In response to a SF fan query about computers that can interpret law, I just finished "Why Call Them Back from Heaven" by Clifford Simak. Although a minor feature of the story, the law of the land dictates the use of jury trials in which the jury is a machine. A couple of paragraphs is devoted to a discussion of how the use of machines has caused lawyers to stick strictly to the letter of the law and objective facts instead of the "sympathy tricks" and other appeals to emotion that are often used in modern day jury trials.
