Here is an interesting question. A restaurant engages in shady business practices. They might be using stolen merchandise. They might be collecting cash payments and not reporting them. They might be cheating their employees regarding their wages. You get the point. Should the hechsher be withdrawn if these issues come to light? Or do we consider the hechsher limited to the kashrus of the food?
I know of a specific instance where there were such issues, and the hechsher was withdrawn, causing the establishment to fold.
I understood that the intent of the hechsher was to oversee the matters related to food. But a hechsher on an establishment implies that everything there is being done in accordance with halacha. I doubt machshirim examine the books. But if such issues do surface, a hechsher should be withdrawn. It’s not just politics.
