This is a "theoretical" question, in a sense...
In Esther 8:5, it says:
וַ֠תֹּאמֶר אִם־עַל־הַמֶּ֨לֶךְ ט֜וֹב וְאִם־מָצָ֧אתִי חֵ֣ן לְפָנָ֗יו וְכָשֵׁ֤ר הַדָּבָר֙ לִפְנֵ֣י הַמֶּ֔לֶךְ וְטוֹבָ֥ה אֲנִ֖י בְּעֵינָ֑יו יִכָּתֵ֞ב לְהָשִׁ֣יב אֶת־הַסְּפָרִ֗ים מַחֲשֶׁ֜בֶת הָמָ֤ן בֶּֽן־הַמְּדָ֙תָא֙ הָאֲגָגִ֔י אֲשֶׁ֣ר כָּתַ֗ב לְאַבֵּד֙ אֶת־הַיְּהוּדִ֔ים אֲשֶׁ֖ר בְּכָל־מְדִינ֥וֹת הַמֶּֽלֶךְ׃
Summarizing the above - Esther requests that King Ahashverush issue a decree to have Haman's written decree returned. In that requests she says, "...And if the thing is kosher before the king".
At the end, the king did not issue the decree that Esther requested. So, this raises some questions.
Which kashrut agency would the king have used to certify this process? Was the reason that the king refused the new decree because he didn't trust that agencies kashrut, and if so, why? What was wrong with the kashrut?
