Common card · No. 463230

In Jewish law, a posek (Hebrew: פּוֹסֵק, romanized: pôsēq; pl. poskim פּוֹסְקִים, pôsəqîm) is a legal scholar who determines the application of Halakha, the Jewish religious law derived from the written and Oral Torah, in cases of Jewish law where previous authorities are inconclusive, or in those situations where no clear halakhic precedent exists. The decision of a posek is known as a psak halakha ("ruling of law"; pl. piskei halakha) or simply a "psak". Piskei halakha are generally recorded in the responsa literature.
