A US judge has sided with a woman challenging the federal government's no-fly policy and ruled that existing procedures to correct mistakes on that list do not provide adequate due process protections.
US District Judge William Alsup in San Francisco ruled on a lawsuit brought by Rahinah Ibrahim, a Malaysian citizen.
The US no-fly policy excludes individuals from commercial air travel if they are suspected of having ties to terrorism, but critics say it is practically impossible to be removed from the list once on it.
US Department of Justice spokesman Wyn Hornbuckle said the government is reviewing the ruling and declined to comment further.
An attorney for Ms Ibrahim, Elizabeth Pipkin, said: "Justice has finally been done for our client, an innocent woman who was ensnared in the government's flawed watch listing system."
The no-fly list is the subject of multiple legal challenges. Ms Ibrahim's case is believed to have been the first to go to trial. The trial took place last month.
Ms Ibrahim attended Stanford University on a student visa, according to court filings. In early 2005, she was detained for two hours at San Francisco's airport because authorities believed she was on the no-fly list.
Eventually, she was allowed to travel to Malaysia. However, her US visa was revoked under a legal provision relating to suspected terrorist activities, though she was not told the specific factual basis for that action. She has not been allowed to return to the United States.
Ms Ibrahim petitioned US authorities to clear her name but received a letter that did not say whether she was still on the no-fly list. She filed a lawsuit, claiming that her inability to return to the United States damaged her professionally.
Ms Ibrahim is currently the dean of architecture at University Putra Malaysia.
In today's ruling, Judge Alsup said the government has conceded that Ibrahim is not a national security threat. She is entitled to be informed whether she is still on the no-fly list, Judge Alsup wrote, and for any mistaken information about her to be corrected.
"The government's administrative remedies fall short of such relief and do not supply sufficient due process," Alsup wrote.
The judge also ordered authorities to disclose more information to Ibrahim relating to the denial of her visa application.
Ibrahim's case proceeded amid continuous litigation over what information about the no-fly list could be made public, and the judge reviewed several pieces of evidence in private at the government's request.
Judge Alsup provided the outlines of his decision in a three page public explanation, though a more detailed order is still under seal. The judge said he believed all of that order should be made public but delayed its release so both sides could propose redactions.
