Arizona v. City and County of San Francisco

The case grows out of fights over the federal government's 2019 immigration "public charge" rule. The Supreme Court is being asked whether Arizona and other states can step in to defend that rule after the federal government stopped defending it, and, if so, whether the rule was lawful or the lower-court judgment should be erased as moot (no longer live).

The case is still pending, and no oral argument has been scheduled yet. Arizona and other states say they should be allowed to defend the 2019 rule if the United States stops defending it.

The dispute could shape who gets to defend a federal policy in court when a new administration changes course. That matters for states, immigrants affected by the public charge rule, and federal agencies trying to revise immigration policy.

The next major step is a scheduling move from the Court, such as setting oral argument or taking other action in the case. No decision window is available yet.

The main fight is whether Arizona and other states can defend the 2019 public charge rule after the federal government stopped defending it. The case also raises whether the rule was lawful or whether the lower-court judgment should be wiped away as moot.

It could affect whether states can keep defending federal policies when presidential administrations change position. That can shape immigration rules and who must follow them while court fights continue.

Watch for the Supreme Court to schedule oral argument or make another procedural move. The record does not show any decision date yet.
