Abe looks through legal loophole for collective self-defence

Reading Time: 5 mins

In Brief

In his quest to make constitutional reform a reality, Japan’s Prime Minister Shinzo Abe is now looking to invoke a controversial court ruling from 1959 as a pretext for reinterpreting the country’s constitution and authorising the exercise of collective self-defence.

The Supreme Court’s verdict in the ‘Sunagawa case’, as it has come to be known, states that the Japanese constitution does not prevent Japan from taking ‘defensive measures that are necessary in order to maintain the peace and security of Japan’. According to Abe’s advisory board this ruling can be interpreted as allowing collective self-defence. The move has been heavily criticised by Japanese legal scholars and ordinary citizens who are feeling increasingly uncomfortable with Abe’s unabashed desperation for changing and reinterpreting the constitution.

The Sunagawa case came about after, in July 1957, seven Japanese demonstrators were arrested for illegally entering the premises of a US air base in the city of Sunagawa (now, Tachikawa), in protest against the base’s expansion.

The judgment delivered by the Tokyo District Court in 1959 found the presence of the US army in Japan to be unconstitutional. Judge Akio Date ruled that the US army’s presence constituted ‘war potential’, violating the second paragraph of Article 9, which states that ‘war potential … will never be maintained’. The seven defendants were subsequently set free.

The ‘Date verdict’ sent shockwaves through Japan and the United States. Had this ruling been allowed to stand the US-Japan Security Treaty would have been thrown into jeopardy.

Realising the gravity of the situation the Americans took expeditious action. Telegrams (declassified in 2008) between the US ambassador to Japan, Douglas MacArthur II, and the then US Secretary of State, Christian Herter, reveal American interference in the legal procedures of the Sunagawa case. The emerging picture raises questions about Japanese autonomy and judicial integrity, and for the Abe administration to now uphold this case as authority for strengthening Japan’s autonomy is an irony of history.

The cables reveal, among other things, that MacArthur on several occasions met privately with Japanese foreign minister Aiichiro Fujiyama. In the first meeting — the very day after the District Court’s verdict — MacArthur urged Fujiyama to convince the cabinet to appeal to the Supreme Court. Four days later, they did.

But more problematic is MacArthur’s frequent secret meetings with his ‘friend’ the Supreme Court chief justice Kotaro Tanaka who presided over the appeal. The full extent of these exchanges is not known, but it seems clear that Tanaka breached legal confidentiality by revealing vital information about the positions and inclinations of the 14 other justices. It is also speculated that he pressured them to fall in line. Both the Japanese foreign minister and the chief justice were thus unduly influenced by MacArthur.

The US also instructed the Japanese prosecutor’s office to tell misleading half-truths. A Japanese foreign ministry official informed MacArthur that the defence was planning to demonstrate the unconstitutionality of US forces in Japan by arguing that Japan-based units of the US fleet were used in the Taiwan Strait crisis of 1958. The US subsequently told the prosecutor’s office to say that although the Seventh Fleet was used in the Taiwan Strait crisis, it did not operate from Japanese bases (which was true enough) — an argument that was successfully put forward by the prosecution. Comment about other Japan-based US military units that actually did participate in the crisis was avoided, however.

The Supreme Court overturned the Date verdict in December 1959. This would have major implications for Japan as a constitutional state. The American military presence in Japan was ruled neither constitutional nor unconstitutional. In fact, the judgment stated that deciding on the constitutionality of ‘highly political matters’ appertaining to the security of Japan, ‘such as the Security Treaty’, was outside the judiciary’s purview. A dangerous precedent was thus set that, if taken advantage of, would give the government unwarranted leeway for ignoring the constitution.

Abe now looks to use the Sunagawa case as a pretext for exercising collective self-defence.

While the Japanese constitution does not say anything specifically about collective self-defence, the consistent interpretation by all Japanese post-war governments has been that Article 9 prohibits Japan’s participation in collective security arrangements. By blowing the dust off the Sunagawa case, Abe now thinks he has found a loophole.

Abe risks, however, opening Pandora’s box. The Sunagawa case after all originally ruled the US military presence in Japan to be unconstitutional. American interference and Japanese servility is suspected of playing a major role in overturning this original judgment at the Supreme Court. By championing the Sunagawa case, Abe may inadvertently direct attention to the dubious proceedings through which the final verdict was ultimately reached, reopening long-forgotten questions about the constitutionality of the US military presence in Japan.

But the greatest fear is that the Sunagawa case will allow Abe to simply ignore questions of constitutionality on the basis of ‘political importance’, and that collective self-defence marks the beginning of the emasculation of Japan’s constitution. The Sunagawa case would be far better left in the dustbin of history.

  1. I didn’t know the historical facts about the Sunagawa case, so I’m really shocked. It has always been the topmost priority on the LDP’s agenda to abolish the present Constitution, which, according to them, was imposed on the country by the U.S. in the disadvantageous situation after the WWII.

    This should naturally mean that the LDP is trying to get out of the overwhelming influence of the U.S.

    The fact is, however, the party has always done things to the opposite effect. They have followed the U.S. to wherever it went, and when doing so was difficult because of the Constitution, they paid money to support the superpower.

    And now, it seems to me they are about to do the same again; they are so eager to provide military support to the U.S.’s international operations.

    They say the U.S.-Japan Security Treaty is unilateral in that only the U.S. has the obligation to protect Japan, which is preventing Japan from becoming a responsible member of the international society.

    But we should remember that the U.S. is not such a simply good-natured friend, but rather a clever actor playing on the stage with various diplomatic techniques imaginable.

    Does it hope to maintain the Treaty if the one-sided obligation is what it is all about? There should be certain fruit that they can reap from it and they are not yet ready to give up in the present international situation.

    This article has given me a clear account of what the Abe administration is intending to do, and I think now I know where the uncomfortable feeling comes from that I get seeing the prime minister’s “brave” vision about this country.

    Thank you for such a revealing article.

    • Thank you very much for your kind words. I’m glad to hear that the piece could contribute to your understanding of the Abe administration’s intentions (even though it is a rather unpleasant understanding).

      The US’ meddling in the Sunagawa case was of course highly inappropriate, but it is the verdict which is most worrisome for today’s Japan.

      I find the outcome of the Sunagawa case downright scary since it puts so much power in the hands of those who define what constitutes a ‘highly political matter’. A litteral interpretation of the Sunagawa verdict would render the courts almost powerless to rule something unconstitutional as long as the government insists on the political importance of a matter, such as CSD, for the security of Japan. And, unfortunately, that seems to be the card Abe is looking to play.
