In Ziglar v. Abbasi, the Supreme Court in a 4-2 decision granted a number of high level federal executive agency officials qualified immunity related to a claim they conspired to violate the equal protection rights of a number of undocumented immigrants held on suspicion of a connection to terrorism after September 11, 2001.
State and local government officials can be sued for money damages in their individual capacity if they violate a person’s constitutional rights. Qualified immunity protects government officials from such lawsuits where the law they violated isn’t “clearly established.”
This case doesn’t involve any state or local government officials. But every qualified immunity case matters.
