Multiple Amoraim dispute whether Jewish legal procedure mirrors Persian procedure: some hold that it does, citing rules about which judge speaks first in different cases, while others hold it does not, and instead explain Memukhan's initiative as driven by personal motives unrelated to legal protocol.

“Memukhan said before the king and the princes: It is not against the king alone that Vashti the queen has sinned; rather, it is against all the princes and all the peoples who are in all the provinces of Aḥashverosh the king” (Esther 1:16). What did Memukhan see that led him to leap and offer counsel first? [One can learn] from here that the ignorant leap first. Rabbi Pinḥas and Rabbi Ḥilkiya in the name of Rabbi Simon, and Rabbi Elazar, and Rabbi Yoḥanan. One said: Our legal system is like their legal system, and one said: Our legal system is not like their legal system. The one who said our legal system is like their legal system, it is as we learned (Sanhedrin 32a): In monetary laws, and in matters of ritual impurity and purity, one commences from the greatest judge. In capital laws, one commences from the side. The one who said that our legal system is not like their legal system, what is the significance of “Memukhan said?” [It is comparable to:] The statement of Rabbi Yehuda appears to be correct. [Likewise:] The statement of Memukhan appears to be correct. Rabbi Yoḥanan said there are three amora’im [who explained why Memukhan sought to depose Vashti]. One said: Because she would slap him with her slippers on this side and that. Another said: Because she did not invite his wife to the women’s banquet. And the other said: Because he had a daughter and he sought to marry her to royalty. The one who said: Because she would slap him with her slippers on this side and that, it is as he said: “It is not against the king alone that Vashti has committed an offense” (Esther 1:16). And the one who said: Because she did not invite his wife to the women’s banquet, it is as he said: “For the queen’s deed will get out to all the women, rendering their husbands contemptible in their eyes” (Esther 1:17); that [indicates that] she was not there. And the one who said: Because he had a daughter and he sought to marry her to royalty, as he said: “And may the king grant her queenship to another who is worthier than she” (Esther 1:19).
