Pekoske v. Cook County, Illinois

(1) Whether entities that are not subject to the public-charge ground of inadmissibility contained in Immigration and Nationality Act, and which seek to expand benefits usage by aliens who are potentially subject to that provision, are proper parties to challenge the U.S. Department of Homeland Security's final rule interpreting the statutory term "public charge" and establishing a framework by which DHS personnel are to assess whether an alien is likely to become a public charge; and (2) whether the final rule is likely contrary to law or arbitrary and capricious.
