Some #states — including #California, #Maine, #Massachusetts & #NewJersey — have enacted laws along the lines that Prof Amar proposed, though they are largely untested, & #Illinois recently adopted one tailored to address the conduct of #ICE agents.

The IL #law says that lawsuits may be filed “against any person who, while conducting #civil #immigration enforcement, knowingly engages in conduct that violates the Illinois Constitution or the #UnitedStates #Constitution.”
The #Trump admin promptly sued #Illinois, saying the #law violated the #Constitution’s #SupremacyClause, which generally prohibits #states from enacting measures at odds with #FederalLaw. Whether to allow lawsuits against #federal agents for violating the federal #Constitution, the admin’s complaint said, “is a policy choice for Congress.” [ridiculous]
Professor Amar said aspects of the IL #StateLaW might be problematic, but that its core idea is sound.
