Judge Jon S. Tigar of the US District Court for the Northern District of California said the proclamation issued on November 9 by President Donald Trump was an effort on the president's part to rewrite immigration laws.
President Donald Trump issued the proclamation earlier in November as a matter of what he called national security as a caravan of thousands of Central American migrants made its way through Mexico towards the U.S. border.
Immigrant-rights groups sued, arguing the roundup was unfair after so many years and urging that the migrants be given a new chance to claim protections here.
Migrants from across Central America have been travelling north for weeks towards the US-Mexico border.
The judge did not immediately issue a nationwide "Temporary Restraining Order" that would block the reforms, as hoped by the pro-immigration groups.
Two Fridays ago, Trump promulgated rules that would deny asylum to the marching horde of migrants who "intend to enter the United States unlawfully" and seek asylum even though most "will not be eligible".
Tigar serves as a judge on the U.S. District Court for the Northern District of California. The method should, in principle, only at official border crossings. Trump announced the move earlier this month, apparently in response to the Central American migrant caravans that he turned into a major flashpoint in the run-up to the midterm elections.

Air sirens sound in Hof Ashkelon region, Hamas fires at southern Israel
Israel and Palestinian fighters in Gaza have fought three wars since 2008, and recent months have raised fears of a fourth. Israeli Prime Minister Benjamin Netanyahu convened his Security Cabinet Tuesday to plot a way forward amid the fighting.
"Let me be clear: This court, from a chamber in San Francisco, has replaced the President's judgment with regard to the fully delegated authority to determine what is a true national security threat to our nation's sovereignty.
If you try to enter our country without authorisation, you have broken the law of the United States, you will be detained, prosecuted and repatriated". "Today the courts were clear: Trump's attempt to obliterate decades-old US and worldwide law ensuring a right to safe haven from persecution and violence will not stand". "Every case that gets filed in the 9th Circuit, we get beaten and then we end up having to go to the Supreme Court, like the travel ban, and we won".
The agencies also said that military, foreign affairs and other needs exempted them from the normal Administrative Procedure Act requirements for public notice and comments about the rules changes.
"There is no justifiable reason to flatly deny people the right to apply for asylum, and we can not send them back to danger based on the manner of their entry", Gelernt said.
At the same time, officials are also limiting the number of migrants who can apply for asylum each day at the official ports of entry.
Administration officials said the asylum law changes were meant to funnel migrants through official border crossings for speedy rulings instead of having them try to evade such crossings on the almost 2,000-mile (3,200-kilometer) border.
Some have already arrived at Tijuana, a Mexican city on the border with California, where many locals are protesting against their arrival, screaming at the migrants to "Get out!"
The Trump administration is vowing to continue fighting for new policies that only allow asylum seekers to enter the United States at official ports of entry.
"The crisis is real and it is just on the other side of this wall", she said.
