Quote from Spearhead:
If I'm the residential owner that sold out to the guy, and my real estate broker didn't tell me about the zoning change, I probably have grounds for a lawsuit.
I do think this is one of the ways for corrupt politicians to enrich themselves. Happens a lot in developing nations.
but it is not illegal and the person buying it would not go to jail. Besides, the realtor would have no idea, because it is not public information yet.
also, inside information cases arent easy to prosecute, specially for hedge funds that are in and out of positions all day... these cases are prbably brought forth by wistle blowers
