Avodah Zarah 37: The Not-So-Permissive Court

Note: Previously labeled Daf 37, "A King's Table," was really the Daf 38 episode, sadly on account of human error. This episode the real Daf 37, "The Not-So-Permissive Court."[Who's Who: Rabbi Yehudah Nesiah, not to be confused with Rabbi Yehudah HaNasi] With a case in his name - regarding the discussion of oil that originates with non-Jews, and when that was then permitted for use by Jews, and a question about permitting the bread of non-Jews. But the sages were concerned that they would labeled a "permissive" court. [Who's Who: Yosi ben Yoezer and the Zugot] Plus, a divorce issued on condition of, for example, the husband not returning in X amount of time, or example more than a year. Also, vegetables that are boiled by non-Jews are prohibited to Jews, but why? Is changing the food (through cooking or grinding) the issue?
