Posek (Hebrew פוסק, , pl. Poskim, פוסקים) is the term in Jewish law for "legal decisor" - a rabbi who decides the Halakha in cases of law where previous authorities are inconclusive. A posek may often serve as a Dayan ("judge") on a Beth Din ("court of Jewish law").
The decision of a posek is known as a psak din or psak halakha ("ruling of law"; pl. piskei din, piskei halakha) or simply a "psak". In Hebrew, פסק is the root implying to "stop" or "cease" - the posek brings the process of legal debate to finality. Piskei din are generally recorded in the responsa literature.
Formulating a ruling (psak din)
A posek will base a
psak din on a study of all relevant
precedents in light of a careful analysis of the
underlying legal principles. The Posek will therefore be thoroughly versed in
rabbinic literature and must be a master
Talmudist.
In formulating his ruling, the Posek will have studied the application of the halakha through consideration of all relevant legal precedents as recorded in the responsa literature - and all relevant codified law (with an emphasis on the Shulkhan Arukh) - and will have mastered the underlying principles in that area through study of the relevant Talmudic tractates with commentaries.
This analysis will entail tracing the development of the corresponding legal material in the Rishonim (early Middle age rabbinic authorities, such as Maimonides or Rashi) through the Shulkhan Arukh (the "Code of Jewish Law"), and finally a close analysis of the works of the Acharonim (rabbinic authorities from about the 1500s onwards) discussing the halakha as recorded in the Shulkhan Arukh.
The role of the Posek
Orthodox Judaism
In
Orthodox Judaism poskim will not overrule a specific law, unless based on an earlier authority: a posek will generally extend a law to new situations, but will not
change the Halakha; see
further under
Orthodox Judaism. (Thus for example, some Halakhic rulings related to electricity when it was new, were derived from rulings concerning another form of human-managed energy, "fire", but that view was subsequently modified as the nature of electricity was clarified when used as an
electrical circuit.)
Poskim play an integral role in Haredi Judaism and Orthodox Judaism. Particularly in the Haredi world, each community will regard one of its poskim as its Posek HaDor ("Posek of the present Generation"). For Lithuanian-style Haredi world it is probably Rabbi Yosef Shalom Eliashiv. For the Sephardi Jews it is probably Rabbi Ovadia Yosef. Hasidic Jews rely on their own Rebbes or leading posek appointed by their Rebbes. Modern Orthodox Jews may select a posek on a more individual rather than a communal basis, although customs vary.
Conservative Judaism
Conservative Judaism and
Masorti Judaism may re-interpret or even change a law through a formal argument. There are a some poskim in the Conservative movement, e.g. Louis Ginzberg and David Golinkin. In addition, the Conservative movement's
Rabbinical Assembly maintains a
Committee on Jewish Law and Standards, whose decisions are accepted as authoritative within the Conservative movement. The rulings of any one individual rabbi are considered less binding than a consensus ruling.
Reform Judaism
Poskim are not found in
Reform Judaism and
Reconstructionist Judaism, as these movements stress individual autonomy for interpretation of biblical and oral law. Nevertheless, since these movements consider Jewish law for various decisions, responsa on halakhah have been written by some Reform Rabbis, including Solomon Freehof and Walter Jacob. Full text collections of Reform responsa are available on the movement's website.
