oh Erictheblue~ Get in here, you may well die from funny.
I can't remember the last time I read something that made my head hurt this much. I only managed to get to page 2 before I had to stop.
Is it even theoretically possible to foreclose on a government department?
Yes and no. Property of some kind is required to foreclose. In theory, if the government agency had mortgaged a property they own (like their headquarters building), the bank that owned the mortgage could foreclose if the government agency defaulted. However, that wouldn't close the agency; it would only transfer ownership of the property (i.e. HQ building) to the bank. The agency itself would still exist, since they can only be disbanded by either executive order or act of Congress. (Executive order would only work if the agency was originally created by executive order. I can't think of any agencies like that, but there may be a few.)
