TEMPLE OF PREAH
V.
Location of the
Temple
INITIAL OF THE CONFLICT
• The present boundary is the result of treaties which were negotiated in
1904-07 and which determined that the line was generally to follow a
specified watershed in this area.
• The watershed line at Preah Vihear followed the edge of the escarpment,
with the natural result geographically of enclosing the temple within
Thailand.
• However, the maps which were later produced by a French firm, at the
request of the Siamese Government, deviated from the watershed line at
Preah Vihear so that the temple was shown as being in Cambodia which,
until 1953, was a part of French Indo-China.
•In 1949, the French Government protested on learning
that Thai troops had been stationed at Preah Vihear. No
explanation resulted and Cambodia, having become
independent in 1953, instituted the present proceeding
before the International Court of Justice in 1959, asking
that it be declared the sovereign of the area in question.
CASE CONCERNING THE TEMPLE OF PREAH VIHEAR
(CAMBODIA V. THAILAND) [1962]
• The Court ruled in favour of Cambodia by a vote of nine to three.
• The watershed was probably due to a topographical mistake.
• The Court give 2 alternative:
(1) that the two countries adopted the maps at the time of their publishing as
officially delimiting the international boundary; and
(2) that the concept of preclusion now prevents Thailand from claiming sovereignty
over the territory.
THE CONCEPT OF ACQUIESCENCE
• The Court concluded that the circumstances were such as to impose on
Thailand a duty to inspect the maps, and a failure to protest was to be taken
as a tacit adoption. This conclusion was based on the concept of
"acquiescence" which protects a country having taken a position adverse to
the interest of another, where the other fails to protest within a reasonable
time.
• The theory is that the first country may have relied on its own position and the
other country ought to be estopped to contest the result at a later time. This is
said to be "an essential requirement of stability" in the international sphere.
THE CONCEPT OF ACQUIESCENCE CONT..
• Acquiescence may have relevance either with respect to changes in the status
of international rights and customs, or with respect to modification of treaties,
as in the instant case. However, for the acquiescence to be effective, it must be
under circumstances from which consent on the part of the adversely affected
nation could reasonably be inferred
A PLEA OF ERROR
• Thailand's duty to inspect the maps also prevented it from claiming that any
adoption at the time of publication was vitiated by the undetected error.
• A plea of error will not be allowed in international law where the parties
could have avoided it, and here the circumstances were such as to put
Thailand on notice of possible error.
PRECLUSION THEORY
•"Preclusion" in international law is the process by which
one nation acquires sovereignty over an area by long
possession adverse to the real sovereign.
•The assertion of sovereignty in the publication of the maps
by Cambodia, and continued acts in relation to the temple
amounting to a continued claim to ownership.
RESULT
CAMBODIA WINS
