As the debate continues in Japan's Diet this month over a new Antiterrorism Special Measures Law (ASM Law) authorizing Japanese naval force activities in the Indian Ocean, serious attention must be paid to the issues of exactly how such activity is to be limited, and how the Diet can meaningfully monitor compliance with such limitations.
These are not simply political or operational issues, but constitutional issues.
The current draft of the ASM Law purports to authorize the Maritime Self-Defense Force (MSDF) to supply fuel to coalition forces engaged in maritime interdiction operations related to Afghanistan. The law would restrict, among other things, the MSDF's area of operations, its involvement in any use of force, and the purpose for which the fuel it provides may be used. These limitations have been explained as being necessary to ensure that Article 9 of the Constitution is not violated.
