What was the case here? The whole story from all sides, not just hearsay.
Let’s look at all the property records on the sale. We know from Bezalel’s posting who was in charge of the sale. Let that person provide all the documentation he has and let’s hear from the rabbonim (if any) who approved the sale as well as those who objected to it. If there were rabbonim on the Vaad Halacha who should have been consulted about the sale but were not, how did it go forward?
There are too many unanswered questions about this sale. Let’s hear those answers and have an independent Chacham determine if there was impropriety.
