A federal court has blocked President Donald Trump’s executive order on sanctuary cities on the grounds that it is unconstitutional, in another legal setback for the administration.

美国一家联邦法院以违宪为由，封杀了总统唐纳德•特朗普(Donald Trump)关于庇护所城市(sanctuary cities)的行政令，这是特朗普政府遭遇的又一个法律挫折。

The nationwide injunction granted on Tuesday by a federal judge in San Francisco will prevent the executive order, signed just days after Mr Trump’s inauguration, from being enforced while its legal merits are debated.

旧金山一名联邦法官周二颁发的这项全国性禁制令，将禁止该行政令在其法律理据目前存在争议的情况下付诸实施。特朗普在就职仅数天后就签署了这项行政令。

“This is a very aggressive use of the injunction authority,” said Leon Fresco, an immigration lawyer who served in the Department of Justice under President Barack Obama, “ . . . using the president and attorney-general’s statements to presume the worst possible interpretation of the sanctuary city executive order.”

曾在巴拉克•奥巴马(Barack Obama)担任总统期间供职于美国司法部(DoJ)的移民律师利昂•弗雷斯科(Leon Fresco)表示：“这是一种对禁制令权力的非常激进的使用……利用总统和司法部长的声明，来假定对庇护所城市行政令的可能最坏的解读符合现实。”

The executive order threatened to cut federal funding from “sanctuary cities” that do not co-operate with federal immigration authorities, as part of the president’s plan to crack down on illegal immigration.

特朗普的这项行政令威胁要对不与联邦移民当局合作的“庇护所城市”断供联邦资金，此举是他遏制非法移民的计划的一部分。

The decision marks another stinging courtroom defeat for the president and attorney-general Jeff Sessions, a former federal prosecutor. Like earlier court rulings rejecting Mr Trump’s controversial travel ban, the sanctuary cities decision underscores the damage Mr Trump’s own words have done to his legal position.

上述法官作出的裁决，是特朗普和曾任联邦检察官的司法部长杰夫•塞申斯(Jeff Sessions)遭遇的又一个难堪的法庭挫败。正如早先的法庭裁决否决了特朗普备受争议的旅游禁令一样，这项庇护所城市裁决凸显出，特朗普自己所说的话已对其法律地位造成多么大的伤害。

“This decision clearly and convincingly puts the president on notice that anything they say can and will be used against them in a court of law,” said Mr Fresco, a partner at Holland & Knight in Washington.

弗雷斯科表示：“该裁决明确无疑地提醒总统，他们说的任何话，都可能且将会在法庭上被用来陷他们于不利。”弗雷斯科现为律所Holland & Knight驻华盛顿的合伙人。
