Jurisdiction
State Jurisdiction over Territory
Territory
Oppenheim:
a defined portion of surface
of the earth subjected to the sovereignty of a state
state w/out territory
impossible but it may be very small
importance of state territory is that
it is the space within which state exercises supreme authority
Land territory is the essential requirement (sine qua non) of statehood & the most potent display of state sovereignty.
Principal Modes of Acquisition of Territory: Roots of
Title
Conquest
Cession
Occupation
Acquisitive
Prescription
Accretion, Avulsion & Erosion
All of these modes of acquisition must be accompanied by the intent to assert or exercise sovereignty (animus possidendi).
Conquest (valid until 1928):
assertion of effective
sovereign control over territory through military conquest
requires actual
possession (factum) and intention to take over (animus)
rendered obsolete
by Kellogg-Briand Pact & reinforced by Declaration on the Rights and Duties
of States (1949) & Friendly Relations Declaration (1970)
cannot even
acquire in self defence
Israeli occupation of territory after 1967 war
illegal force cannot give good title'
likewise denunciation of Iraqi
attack on Kuwait
Occupation:
means of establishing title over terrae
nullius
occupation follows discovery' discovery insufficient to
establish title
discovery must be accompanied by animus' (intention) to
exercise sovereignty
tribal peoples do not live in terrae nullius
Western Sahara (1975)
effective, continuous & peaceful display of
exclusive territorial sovereignty
not necessary to prove activity at all
points in time to give rise to presumption sufficient to show some state
activity but existence of competing claims will entail stricter proof
requirements: Island of Palmas (1928)
Acquisitive Prescription:
displacement of
sovereign through competing displays of sovereignty which ultimately overtake
the former sovereign's title
where occupation can only work re terrae
nullius, AP can take place over any territory by continuous display of de facto
sovereignty
requires evidence of a great deal of state activity
Cession:
transfer of sovereignty over territory by
agreement
requires change in law (treaty) & change in fact (transfer of
possession)
usually in a peace treaty after war
distinguish from
"renunciation" (unilateral renunciation of territory) & "abandonment"
(unilateral withdrawal leaving terra nullius)
emergence of principle of
self-determination has made cession less likely
Accretion, Avulsion & Erosion:
natural processes
which result in extension/reduction of land thereby extend/reduce extent of
sovereignty
Principal Legal Regimes Re: Relation of States to "Territory"
Full Sovereignty
territory over which a state
exercises all of the jurisdictional competencies permitted by international
law
Res Communis
no state is sovereign but all states
can exploit the area for individual benefit (e.g. high seas, outer space)
some states enjoy greater entitlements or jurisdiction (e.g. coastal)
Terra/Res Nullius
land which is capable, but is not
presently subject to state sovereignty
Common Heritage of Humankind (CHH)
not subject to
state sovereignty or exploitation for individual benefit exploitation allowed
only for benefit of international community (e.g. deep seabed & subsoil,
Moon, celestial bodies)
Territorial Sovereignty: 3D
"Territory" (thus sovereignty) is broader than land, & includes subsoil, waterways & territorial sea, & airspace.
Subsoil:
Principle of Appurtenance:
territorial
sovereignty extends to subsoil
Lakes & Rivers:
sovereignty extends to all
lakes, canals, & rivers bounded by land territory
in the case of bodies
of water between adjacent riparian states, the international boundary is set by
treaty or by application of a median line (customary rule)
rights in
waterways are exclusively held by riparian states free to establish regimes to
the extent of their sovereignty
riparian states on internationalised
watercourses (e.g. Danube, Rhine) have resisted any encroachment on their
exclusive riparian rights, choosing instead to permit access/use through
treaties
Airspace
Whatever rule applies to the land applies to the airspace
above
territorial sovereignty extends to airspace
other states may
only use airspace with agreement/authorisation of the state, regardless of type
of use emerged in wake of military/civilian aviation
there is no agreement
on an upward limitation, but 100-110 km above sea level has been
suggested
Chicago Convention of International Civil Aviation
(1944)
unscheduled civil flights may enter without permission (provided
they acquiesce to requests to land)
prior authorisation is required for
scheduled civil flights to enter
state maintains privilege to revoke
permission for national security or emergency reasons
1980 Protocol to Chicago Convention:
no use of force
against civilian aircraft instead, interception, escort, etc. required
codification of customary prohibition on use of force to deny civilian
entry
such prohibition was clearly acknowledged by 1983 downing of Flight
KL007 denounced by international community
established International Civil
Aviation Organisation
almost universal
affirms customary rule of
absolute sovereignty over airspace, but sets out permissive regime for its use
by foreign aviators engaged in civil & innocent use
Jurisdictional Airspace Rights
Jurisdictional airspace rights extend beyond land, but do not constitute an extension of territorial sovereignty. State practice shows that coastal states may extend a limited functional jurisdiction into the high seas for security reasons.
Jurisdiction over Persons
Jurisdiction: denotes the exercise of powers by a state over events, persons, and property
A state has sovereign authority within its borders, therefore its power to legislate cannot be denied. May exercise its jurisdiction over the subject matter of anything within its territory.
Bases for Criminal Jurisdiction
There are 6 basis for jurisdiction not all universally accepted
Because of the several bases, there may be concurrent jurisdiction.
1. Territorial Principle: state where crime committed has
jurisdiction. This is the primary working rule. Territory includes the land
mass
subjective (or initiatory principle): the act may be deemed to have
been committed in the place where it commenced.
objective/effects (or
terminatory) principle: the state where the act is consummated or where the last
constituent element of the offence occurs has jurisdiction (Lotus
Case)
2. Nationality Principle (active): The nationality of the
offender as the basis for jurisdiction is used extensively in civil law
countries. Common law countries, however, have been reticent in their use of
this principle. Canada uses this principle only for treason, war crimes, crimes
against humanity, and various international terrorist offences.
3.
Nationality Principle (passive): (seldom used) claim to jurisdiction over
foreign nationals on alien soil for crimes committed against the claimant
country's nationals not many countries pursue this rule generally. Mexico
followed in Cutting case ICJ opposed this principle in Lotus case.
4
Protective Principle: A state may exercise its jurisdiction over acts committed
abroad that are prejudicial to its security, territorial integrity and political
independence. (i.e. espionage) problem of states broadly interpreting
security'
5. Universality Principle: A state claim jurisdiction over all
crimes anywhere (generally considered contrary to intl law) generally seen as
less objectionable when applied to acts that are generally considered
universally criminal (war crimes, terrorism, hijacking, piracy, war
crimes)
6. By Agreement: Jurisdiction of one state with in the territory of
another state may always be granted by agreement. Ex. Am. criminal laws operate
on Am. military bases in Canada.
