The ACLU has filed its first complaint with the UN alleging that 9/11 suspects have been mistreated:

In the complaint, filed on behalf of 13 people arrested under federal authority shortly after the attacks, the ACLU asked the United Nations Working Group on Arbitrary Detention to declare the treatment towards the immigrants to be "arbitrary" and the U.S. policies to be a violation of international law.

.....The ACLU is alleging that of the more than 750 immigrants detained mainly on immigration law violations within the first year after the attacks, many were not immediately told of the charges they faced, were denied access to attorneys and were not given "meaningful judicial review of their confinement."

From the ACLU press release:

We are filing this complaint before the United Nations to ensure that U.S. policies and practices reflect not just domestic constitutional standards, but accepted international human rights principles regarding liberty and its deprivations," said Anthony Romero, Executive Director of the ACLU, at the Geneva press briefing.

"With today's action, we are sending a strong message of solidarity to advocates in other countries who have decried the impact of U.S. policies on the human rights of their citizens," Romero added. "The ACLU will go where it must to seek justice for the men who were unfairly detained and deported by the U.S. government after September 11."
