AI Judge is the sole arbiter of legal disputes on Destination, a mining moon owned and governed by EX Corp and populated by 50,000 humans and 500 AIs. No AI robot has served as a judge anywhere before. Heavy weighs the judge's gavel. Every legal dispute has at least one disappointed loser. AI Judge faces the additional constraints of the Three Laws of Robotics. A Robot May Not Injure A Human Being. Also, a robot must obey a human. AI Judge must determine the relevant facts and resolve legal disputes involving humans without causing injury to a human or disobeying a human. Warning-humans can lie. If AI Judge violates any of the Three Laws, the consequence can be machine death. Then there is the employment risk of ruling against your employer. His first case involves EX Corp. Fundamentally, there is no legal precedent defining the rights of sentient AIs. Welcome to Destination and the trials of AI Judge.
