One jurists's 'discovery' of the ruling of law for a specific case would not have been invalidated by some other jurist's discovery of a different ruling for that case; only God could choose between them, and until the Resurrection (or in the case of the Shiah, the return of the Twelfth Imam) God had left the matter to the jurists, and the first actual judgment was final, as otherwise there would have been an infinite regress of opinions without any final judgment. For the Shiah, ... resistance to a single written code was even stronger; the jurisconsult's right to describe the law in his own way was the very essence of the doctrine that had revived the jurisconsult school at the end of the 18th century."
