I don't quite agree. Under the 'territorial principle', a state may claim jurisdiction over persons and events inside its own territory. Under the 'nationality principle'. the government of a citizen can obtain jurisdiction over its citizen even when that citizen is abroad. Both principles express a possibility rather than an absolute, and both are generally interpreted more narrowly than a state's full jurisdiction over its own citizens on its own territory. Illegal aliens are potentially subject to US jurisdiction, in the sense that they can be tried for crimes committed while illegally present, but that is far from being subject to the broad jurisdiction of the US government.
This is an interesting distinction you’re making (territorial vs nationality principle), Pollster, & I’m not familiar with it (yet). This is beyond- far more technical, than the simple definition of ‘’jurisdiction’’.
You’re an attorney? Or at least a student/ former of law? These are surely legal nuances unfamiliar to mere mortals. Help us out, please. The better people understand the hows & whys of these invaders & their enablers, the sooner we might figure out the most effective way to stop it.
Thank you for your post!
