On 5 October 1995, Japanese Prime Minister Murayama stated that
the Treaty of Annexation between the Empire of Japan and the
Empire of Korea of 22 August 1910 was concluded "legally". The
remark was merely a restatement of long-held official stance of the
Japanese government. Yet, it attracted harsh criticism from the
governments of the Republic of Korea (South Korea) and the
Democratic People's Republic of Korea (North Korea), both of which
hold the conviction that the 1910 treaty was concluded illegally.
This article attempts to examine the arguments of both sides in
regard to their legal validity. Hence, full historical analysis is not
within the scope of this paper. However, to understand why the
Korean governments reacted so strongly, it is necessary to view the
dispute in historical context.
-
The fundamental objection of the Koreans to Japan is that it fails to
face sincerely to its sins of the past. It is their conviction that Japan
has continuously avoided admitting its military past and the atrocity
associated with their colonial occupation. They voiced concerns each time
when Japanese politicians and prominent persons made remarks which, in
their view, had intentions to conceal, play down or justify the actions it
committed while it ruled Korea. These remarks, according to Koreans, were
evidences of Japanese people's denial of their history of oppression
against their neighbours and their attempt to glorify their colonialistic
past.[1]
-
Prime Minister Murayama's comment was yet another addition to
this long list of controversial remarks made by Japanese politicians. The
latest incident concerns the status of the 1910 Annexation Treaty. This
treaty established the colonial rule of the Japanese Empire over the
territory of Korea. Japan's official stance has been that the Treaty was
concluded legally and it remained valid until the Japanese colonial rule
was ended as a result of its defeat in the World War II. On the other
hand, both of the Korean governments claim that the 1910 Treaty was
concluded under the coercion of Japanese military power and therefore is
illegal and void ab initio. The reason behind the Korean claim must be
appraised here according to international law principles.
-
To claim that the 1910 Treaty is illegal and void, one must prove the
existence of international law rules to that effect at the time of the
conclusion of the Treaty. On the other hand, arguments opposing the
existence of such a rule in 1910 claims that to argue so would be
tantamount to rejecting the legitimacy of treaties of peace, such as the
Potsdam Declaration of 26 July 1945, the acceptance of which by the
Japanese government ended the World War II.[2]
-
Article 51 of the Vienna Convention on the Law of Treaties provides
that: "The expression by a State of consent to be bound by a treaty which
has been procured by the coercion of the representative of that State
through acts or threats directed against him shall be without any legal
effect."[3] This article is widely regarded as codifying the existing
customary rule of international law.[4] However, scholarly opinions are
divided on the status of Article 52, which states the rule applying the
case of coercion to a State itself, rather than the representative of a
State, as in a military conflict situation. Article 52 states that:"A
treaty is void if its conclusion has been procured by the threat or use of
force in violation of the principles of international law embodied in the
Charter of the United Nations."
- It is understood that, by inserting this clause, the contracting
parties intended to make the provision applicable against treaties
concluded before the adoption of the Charter of the United Nations.[5] The
provision particularly relevant in this case can be found in Article 1
(1), where it reads:
"[The purposes of the United Nations are:] To maintain international
peace and security, and to that end: to take effective measures for the
prevention and removal of threats to the peace, and for the suppression of
acts of aggression or other breaches of the peace, and to bring about by
peaceful means, and in conformity with the principles of justice and
international law, adjustment or settlement of international disputes or
situations which might lead to a breach of the peace; ..."[6]
-
This clause clearly indicates that 'acts of aggression and other breaches
of the peace' are forbidden. In this sense, the Annexation Treaty would
have been clearly in breach of the principles embodied in the Charter.
However, the principle's retroactive effect must be argued with caution.
While international courts have upheld a provision of a treaty that is
clearly intended to have a retrospective effect[7], the provision of the
Vienna Convention lacks the specificity to be applicable to the present
case. Therefore, the principle of intertemporal law should prevail in
this situation.[8]
-
The principle of intertemporal law demands that the validity of legal
rights must be determined by the law in effect when the right is created.
This means that a treaty concluded legally in the light of international
law in effect at the time of its conclusion is legal. The philosophy of
de-legitimisation of war, which is the basis of the 'principles of
international law' mentioned in the quoted provision of the Vienna
Convention, does not go back long enough in history to make Annexation
Treaty which was signed in 1910 illegal.
-
In the nineteenth century, states' right to resort to war was regarded
as inalienable part of their sovereignty. The only international legal
regulation was concentrated on determining what is admissible behaviour in
the act of war (jus in bello). Very early attempts to check the States'
right to resort to war can be seen in the Hague Peace conferences of 1899
and 1907, in which the Convention for the Pacific Settlement of
International Disputes was signed. This Convention established the
Permanent Court of Arbitration, where States with disputes were encouraged
to submit their case instead of resorting to war.
-
Other important legal documents on legal restriction of war include
the Covenant of the League of Nations of 28 June 1919 and the so-called
Briand-Kellogg Pact of 1928. The Covenant of League of Nations provides
that Member States were obliged to take their disputes to the Permanent
Court of International Justice, established by the Covenant, or the
Council of the League of Nations.[9] In the Briand-Kellogg Pact,
contracting States agreed to renounce generally recourse to war for the
solution of international controversies, and as an instrument of national
policy.[10]
-
While these documents witness important philosophical background to
the principle of peace and non-aggression proclaimed in the United Nations
Charter, they alone do not create legal obligation on States to refrain
from exercising military pressure. In the League of Nations system,
States were permitted to recourse to war when the council failed to reach
a unanimous recommendation on the resolution of conflict between them.
The general prohibition of war provided by the Briand-Kellogg Pact is
solely concerned with war stricto sensu, and cannot be interpreted as to
prohibit an act of oppression using threat of war.[11] Therefore, there is
no evidence in international legal documents that, in 1910, an act of
aggression, as the Japanese imposition of annexation on Korea was, did not
possess the legal effect of making a treaty concluded under such situation
illegal and void under contemporary international law principles.
-
Having thus rejected the existence of general international law
principles, we must now turn to the question whether there is a
special circumstance or agreement that supports Korean allegation of
nullity of the Annexation Treaty. Article 2 of the Treaty of Basic
Relations between Japan and the Republic of Korea of 22 June 1965 reads:
"It is confirmed that all treaties or agreements concluded between the
Empire of Japan and the Empire of Korea on or before August 22,
1910 are already null and void".[12]
-
This article was included by the strong insistence of the Korean
delegation and reflects its official stance that the Annexation Treaty was
void before the conclusion of the Basic Relations Treaty. There is a
slight difference of nuance between the Japanese and Korean texts of this
article. While the Korean text is true to the above mentioned stance of
its government, the Japanese text employs the expression that permits the
interpretation that the Annexation Treaty was 'no longer valid' at the
time of conclusion of the Basic Relations Treaty.[13] However, the end
paragraph of the Treaty provides that, in case of conflict of
interpretation between Japanese and Korean texts, the interpretation of
the English text, which is of the same authenticity as the other two,
shall prevail. Therefore, the stance of the Korean government shall be
upheld on the question of interpretation of this article: the 1910
Annexation Treaty was null and void at least sometime before the
conclusion of the 1965 Treaty. The official stance of Japan on this issue
is that the Annexation Treaty was legally concluded and remained in effect
until Korea's independence from Japan.[14] This position is not
inconsistent with the interpretation of Article 2 of the Basic Relations
Treaty discussed above. However, another difficult question arises from
this stance. The date of independence of the Republic of Korea is 15
August 1948 and that of the Democratic People's Republic of Korea is 9
September 1948. Japan maintains that, in relation to South Korea, the
Annexation Treaty became void on 15 August 1948; and in relation to North
Korea, on 9 September 1948. However, the Basic Relations Treaty, citing
the United Nations General Assembly resolution 195(III), recognised that
the government of the Republic of Korea is 'the only lawful Government in
Korea'. Therefore, Japan's stance that the Annexation Treaty remained
valid until 15 August 1948 in the South and until 9 September 1948 in the
North is questionable.[15]
-
The provision of Article 2 of the Basic Relations Treaty does not
witness the existence of agreement between the parties that the 1910
Annexation Treaty was null and void ab initio. However, as the above
discussion reveals, there is no ground to uphold the Japanese government's
interpretation either. The matter is left for the governments concerned
to sort out. In the meantime, the danger of occasional controversy like
the recent one will persist.

[15] For Japanese delegation, the reference to the UN General Assembly
Resolution 195 (III) was crucial. In paragraph 2 of the resolution,
the General Assembly declares that there has been established a
lawful government having effective control and jurisdiction over that
part of Korea [south of 38 parallel] ... (Emphasis added) Japan
stresses that this resolution recognises that the jurisdiction of the
government of the Republic of Korea is limited to the part of Korea,
now called South Korea. Following this interpretation, Japanese
government maintains that unrecognised government of the
Democratic People's Republic of Korea holds de facto jurisdiction over
the part of Korean peninsula north of 38 parallel. The government of
the Republic of Korea disputes this interpretation. See, Osato, "The
Problem of Two Koreas", 18 Japanese Ann. Int'l L. 51, 58 (1974).
