Let's say 20 people own parts of the house in front of yours. It's confusing, so you whine a lot, and suddenly a public auction is triggered?
At the very least, he must understand that he is _not_ the owner, so everything else is kinda moot right?
EDIT: seems like he bought out certain percentages of ownership on these parcels, and there's a law that can help to force a sale when the ownership gets too confusing.
Seems like the sort of law for billionaires wanting to have their own private beach.
