The government might leave judgment on whether to legalize Japan's use of the right to collective self-defense to future debate and avoid mentioning plans to reinterpret the pacifist Constitution when the Cabinet revamps security policy later this month, sources said Monday.

The government is likely to state that the right to collective self-defense is allowed under international law and Japan will "study" how to exercise it, the government sources said.

The ruling coalition, led by the Liberal Democratic Party, has started discussions on reviewing Japan's security framework, but the junior member, New Komeito, remains opposed to reinterpreting the Constitution to lift the long-standing ban on collective self-defense.
