This ruling was expected. The judge had been stalling on making a ruling to make it take time to work its way through the appeals courts and get to the Supreme Court where the policy might actually get ruled unconstitutional.
If I were a betting man, I'd put the odds north of 2:1 that this will be overturned if the current SCOTUS sees it.

Apart from anything else a waste of taxpayer money.
If the judge makes the ruling based on previous rulings made by the higher court, while knowing that the higher court is likely to now overturn those rulings, it is still absurd?
The way the US system works is that lower courts are generally bound by previous higher court decisions, assuming those decisions are germane to the case in question.
