The Supreme Court has given the Trump administration a big win on a controversial immigration rule. The rule called the “public charge” rule would make it harder for immigrants who use or could use public assistance to obtain green cards.

According to The Hill:

The Supreme Court ruled in favor of the Trump administration on Friday night in a case that contested the president’s “public charge” rule, which critics have called a “wealth test” for legal immigrants.

The policy in question, the Immigration and Nationality Act, would make it harder for immigrants who are “likely at any time to become a public charge” to obtain green cards. The policy discourages legal immigrants in the process of obtaining permanent legal status or citizenship from using public assistance, including Medicaid, housing vouchers and food stamps.

The case heard by the court, Wolf v. Cook County, sought to reject the policy’s effect in Illinois. The district court filed a preliminary injunction, which temporarily halted the policy in the state and sent the case to the Supreme Court. On Friday, the five conservative justices ruled in favor of the stay, while the liberal justices opposed it.

The Supreme Court ruled 5-4 in January to lift a nationwide injunction imposed by a federal judge in New York while the case played out in appeals court. Last week, Solicitor General Noel Francisco sent a request asking the court to do the same for an injunction imposed by an Illinois district court.

Justice Sotomayor issued the dissent arguing that the conservative majority is posing a danger by rubber-stamping Trump policies without critically examining the cases before them.
