Three cases against the new ban moved forward on Wednesday.

In Maryland, refugee resettlement agencies represented by the American Civil Liberties Union and the National Immigration Law Center argued in court for a restraining order.

Separately, Hawaii’s attorney general sued, arguing the states’ universities and tourist economy would be harmed by the travel restrictions and also asked that the law be enjoined.

In Washington state, a group of plaintiffs applying for immigrant visas asked U.S. District Judge James Robart in Seattle — who suspended the first ban — to stop the new order.

Washington state, joined by California, Maryland, Massachusetts, New York and Oregon, said in court filings they supported the plaintiffs in Seattle.

To move forward with the lawsuits, the states and groups have to prove harm, or “standing,” which some legal experts have said is difficult to prove because of all the exemptions and waivers in the new order.

The government says the new order only applies to people outside the United States who have not entered the country and do not have constitutional rights.

“Who has the standing in this case if anyone?” U.S. District Judge Derrick Watson asked Hawaii’s attorneys.

A group of 58 tech companies, including Airbnb, Lyft and Dropbox, filed a “friend of the court’ brief in the case saying the order hurt their ability to recruit the best talent from around the world. A longer list of companies — that included giants like Apple, Facebook and Google — filed a brief opposing the first ban in a different court challenge brought by Washington state, which is ongoing.

At the court hearing in Greenbelt, Maryland, on Wednesday U.S. District Judge Theodore Chuang pushed on the question of who would be harmed by the order. Chuang said he would try to issue a written ruling on Wednesday, before the order is implemented, but said it might come afterward.
