Lesson4
All the powers that a government can have are limited to spheres of activity known as jurisdictions. These are described in terms of the location where they operate: soil, land, sea, air. Most recently, the domain of space has been added.
When we speak of “law of the land” we are talking about the law that applies to the land jurisdiction held by a national government, which is different than the law of the sea which is international in nature, or law of the air which is municipal and global. Jurisdictions can overlap like layers of a cake and the same subject matter can be claimed by more than one jurisdiction, however, he/she/it must be operating in a recognizable capacity within that jurisdiction.
For example: Some American nationals go to work for the British Territorial United States (a federal subsidiary) and are required to adopt Dual Citizenship while employed as a federal civilian or military employee. Acting as Americans they are subject to the Law of the Land. Acting as Federal citizens they are subject to the Law of the Sea.
You can see how certain parties might have an interest in dragging you from one jurisdiction to another, in order to obligate and subject you to their laws (and taxes) instead of your own.
