A United Nations legal institution is reporting Turkey to the Security Council because of Ankara's failure to release an international judge who is among thousands of people detained in the aftermath of last year's failed coup.

In January, the Mechanism for International Criminal Tribunals, gave Turkey until Feb. 14 to free Turkish citizen Aydin Sefa Akay and halt legal proceedings against him, saying he is protected by diplomatic immunity.

In a written ruling issued Monday, Judge Theodor Meron says Turkey has not yet complied with the order. Meron says, "this matter shall be reported to the United Nations Security Council."

It is unclear what action, if any, the Security Council will take.

The mechanism deals with appeals and other legal matters left by the U.N.'s tribunals relating to Rwanda and Yugoslavia.
