- What it's about
This case arose from challenges to the federal government's 2019 immigration "public charge" rule. The main dispute at the Supreme Court was whether Arizona and other states could 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 wiped away as moot.
Question presented
1. Whether States with interests should be permitted to intervene to defend a rule when the United States ceases to defend. 2. Whether the Rule is contrary to law or arbitrary and capricious. 3. Alternatively, whether the decision below as to the Rule should be vacated as moot under Munsingwear.
