Statement
Writing responsa (singular: responsum) was probably the chief means by which a Gaon exercised authority over long distances: a 'justice by correspondence' in which he drafted a legal opinion answering a specific inquiry and thereby set a precedent. The responsum has been a major part of Jewish law ever since, dealing with the order of prayers, dietary laws, marriage and divorce, that personal injury and business liability.
