Saying that government lawyers let their zeal for victory in a deportation case outweigh their responsibility to be fair, a federal appeals court last week ordered the United States to provide a haven for a woman facing the likelihood of torture in China.

The woman, Jinyu Kang, an ethnic Korean citizen of China who now lives in New York, had fled a Chinese arrest warrant for giving food and shelter to Korean refugees. Others named in the same warrant and caught by the Chinese police had described beatings, suffocation, electric shocks, sleep deprivation and other forms of torture to get them to disclose details about the human rights group to which they all belonged.

“It is disappointing, even shocking, that the government fails to acknowledge that the evidence is not only strongly in Kang’s favor, but, indeed, compels the conclusion that she will likely be tortured,” said the decision, issued by a three-judge panel of the United States Court of Appeals for the Third Circuit, which covers Delaware, New Jersey, Pennsylvania and the United States Virgin Islands.

The decision details “the horrific experiences” suffered by members of the group, and cites testimony that Ms. Kang’s son, who is still in China, was also tortured by the police during interrogation about his mother’s whereabouts. (Ms. Kang declined to talk about the case with a reporter through her lawyer, Man C. Yam.)
