650 international law
International law accepts that a state may levy taxes against persons not
within the territory of that state, so long as there is some kind of real link
between the state and the proposed taxpayer, whether it be, for example,
nationality or domicile.

A state may nationalise foreign-owned property
situated within its borders,
18
but it cannot purport to take over foreign-
owned property situated abroad. It will be obvious that such a regulation
could not be enforced abroad, but the reference here is to the prescriptive
jurisdiction, or capacity to pass valid laws.
The question of how far a court will enforce foreign legislation is a
complicated one within, basically, the field of conflict of laws, but in
practice it is rare for one state to enforce the penal or tax laws of another
state.
19
Although legislative supremacy within a state cannot be denied, it may
be challenged. A state that adopts laws that are contrary to the provisions
of international law, for example as regards the treatment of aliens or
foreign property within the country, will render itself liable for a breach
of international law on the international scene, and will no doubt find
itself faced with protests and other action by the foreign state concerned. It
is also possible that a state which abuses the rights it possesses to legislate
for its nationals abroad may be guilty of a breach of international law.
For example, if France were to order its citizens living abroad to drive
only French cars, this would most certainly infringe the sovereignty and
independence of the states in which such citizens were residing and would
constitute an illegitimate exercise of French legislative jurisdiction.

Executive jurisdiction relates to the capacity of the state to act within
the borders of another state.

Since states are independent of each
other and possess territorial sovereignty,
22
it follows that generally state

See e.g. Cheshire and North, Private International Law, chapter 8. English courts in general
will not enforce the penal laws of foreign states. It will be for the court to decide what a
foreign penal law is. See also Huntington v. Attrill [1893] AC 150, and Marshall CJ, The
Antelope 10 Wheat 123 (1825). As far as tax laws are concerned, see Government of India v.
