Summary

Anyone who, in good faith and with a reasonable suspicion, reports possible terrorist activity or other suspicious behavior involving passenger transportation to an authorized official is protected from civil lawsuits. That protection does not apply if the person knew the report was false or made it with reckless disregard for the truth. Authorized officials who see or get reports of such activity and take reasonable, good-faith steps to respond get legal protection from civil suits. If an official can’t use the usual “qualified immunity” defense, they are still immune from lawsuits so long as their response was reasonable and in good faith. People and officials found immune can recover reasonable legal costs and attorney fees from the person who sued them. Authorized official: employees or agents tied to passenger transportation security, certain federal agency staff, or police. Covered activity: suspicious acts against passenger transport that threaten safety or involve possible terrorism. Passenger transportation: public transit, buses, intercity rail, passenger vessels and other scheduled waterborne service of at least 20 gross tons, and air travel. Vehicle: as defined in 18 U.S.C. 1992(16). The rule took effect October 1, 2006, and applies to actions and claims from that date onward.
