1. They got a restraining order from a Texas District Court, not a Federal District Court. Texas Civil courts only have jurisdiction in the state of Texas, which in itself is limited.
2. A business can be sold for any value, over or under. Under a democracy, this is perfectly legal.
3. The Texas court is putting a restraining order when the club would be under administration for not paying back the loans; thus, officially owned by the banks itself.
4. Liverpool is in England, Great Britain, which is not a district of the United States, thus any local court does not have jurisdiction over it.
5. The majority of the loans are owed to Royal Bank of Scotland, or RBS, which is controlled by Her Majesty's Treasury; which in itself is a part of the British government. Which, again, is not part of the United States.
6. Other loans are owed to Wells Fargo, which is a California company. Again, a Texas District Court has no power over it.
