Years ago, IIRC, I heard the following from a respectable source:
- By Israeli law, if the רבנות of one city certifies a food as kosher, then the רבנות of any other city must allow that food as an ingredient in factories and restaurants it certifies (not "למהדרין"). Briefly, every רבנות must accept the certification of every other רבנות. (This is also claimed by the Star-K.)
- There is at least one city in Israel whose רבנות is not reliable for כשרות.
- Therefore, there is no Israeli city whose רבנות's (not "למהדרין") certification is reliable for all foods: there's no blanket reliability. Rather, any city's רבנות's (not "למהדרין") certification must be evaluated on a food-by-food basis (though it's possible that every certification it happens to grant at the moment is reliable).
I do not want to get into point #2. That will lead to arguments and, likely, לשון הרע. Rather, my questions are:
- Is there anything wrong with the syllogism? That is, if #1 and #2 are true, is there any reason #3 wouldn't follow?
- Is #1 true? If not, was it ever? Proof, please? Especially, can anyone provide a citation to and quotation of such a law?
