The United Nations is preparing the questions for John Kerry’s Global Test: U.N. panel to frame guidelines on legality of pre-emptive strike. (Hat tip: aboo-Hoo-Hoo.)

Members of an international panel studying United Nations’ operations say the group hopes to lay down clear rules declaring when it is legal for a nation to use pre-emptive military force in its own defense.

The issue grows out of the international controversy over the Bush administration’s decision to invade Iraq without a final U.N. Security Council resolution explicitly authorizing the war, said panel member Gareth Evans, a former foreign minister of Australia.

“I expect the panel to be giving close consideration to what those rules are and how they should be applied and whether an effort should be made to identify generally agreed criteria for the legitimate use of force, whatever the context,” Mr. Evans said during a recent appearance at the Woodrow Wilson International Center for Scholars in Washington.

He made his remarks before last week’s presidential debate in which Democratic nominee Sen. John Kerry’s call for a “global test” on when pre-emptive action is justified became a campaign issue.

U.N. Secretary-General Kofi Annan established the 16-member High-Level Panel on Threats, Challenges and Change in November to study ways to reform the 59-year-old organization so it can better address 21st-century threats to security and peace.

But Mr. Evans, currently president of the International Crisis Group think tank, said much of the panel’s work has focused on establishing detailed guidelines for the use of military force.

“A central reason for our appointment was concern that the U.N., and indeed the whole multilateral security system, was really at a crossroads with the resurgence of unilateralism from you know whom, and increasing willingness to bypass the Security Council,” Mr. Evans said in a clear reference to the Bush administration.
