Whether the Attorney General has absolute immunity from damages suits for allegedly unconstitutional actions taken in performing national-security functions.
Holding
No. The Attorney General is not absolutely immune from damages liability merely because the challenged conduct was undertaken in the interest of national security.
Reasoning
Absolute immunity does not follow simply from the Attorney General's Cabinet rank. Unlike the President, legislators, and certain judicial actors, Cabinet officers do not receive absolute immunity based solely on their position. The Court therefore examined the particular function Mitchell performed rather than his office alone.
The Court found no historical or common-law foundation for absolute immunity for executive officials performing national-security tasks. By contrast, the absolute immunities afforded judges, prosecutors, witnesses, and legislators have deep historical roots and serve functions closely associated with the judicial or legislative process.
National-security work also does not present the same inevitable risk of retaliatory litigation that supports absolute immunity for judges and prosecutors. Judicial proceedings produce identifiable winners and losers who may sue to relitigate their losses, whereas national-security operations are generally secret and are more likely to conceal genuine abuses than to generate baseless suits.
The Attorney General's national-security decisions lack the institutional checks that help justify absolute immunity elsewhere. Political accountability, appeals, and procedural safeguards can correct errors by legislators and judges, but comparable built-in restraints do not reliably protect people subjected to secret surveillance. Because claims of national security can mask serious threats to speech and privacy, the risk of constitutional abuse counseled against complete immunity.
Qualified immunity supplies sufficient protection. Under Harlow, an official is protected unless he violates clearly established statutory or constitutional law. That standard protects officials from insubstantial litigation while still requiring them to hesitate before violating legal rules that a reasonable official should know.
