Challenge to State Law

20 proceedings tracked · Active

The Trump administration filed a wave of offensive lawsuits against individual states, seeking to preempt state laws on immigration enforcement, climate liability, in-state tuition for undocumented immigrants, and voter roll access. Unlike typical defensive postures, the federal government here is the plaintiff, using litigation as a policy enforcement tool. Several fossil-fuel and climate suits have been decided; sanctuary city, tuition, and voter roll suits remain active.
