Law of the United States
A volume on the Foreign Relations Law of the United States, released in 2018, was the first in the Restatement, Fourth, series to be completed; however, rather than being a complete update to the previous volume from the third series on the same subject, it is instead limited to selected topics in treaties, jurisdiction, and sovereign immunity. Other new projects are currently underway as part of the Restatement, Fourth, series on Property.
