LA HB1140

Requires telecommunications providers to implement STIR/SHAKEN call authentication technology, maintain robocall mitigation plans, and take reasonable steps to prevent unlawful caller ID spoofing on their networks

Prohibits providers from knowingly transmitting spoofed caller ID information with intent to defraud or cause harm, and from continuing to carry unlawful traffic after receiving written notice from the attorney general unless corrective action is taken within 30 days

Authorizes the attorney general to bring civil actions for injunctive relief, restitution, and penalties up to $10,000 per knowing violation or $1,000 per negligent failure to implement mitigation measures

Provides a safe harbor from liability for providers that implement required authentication technology, act in good faith to block unlawful traffic, and do not knowingly facilitate spoofing

Requires interpretation consistent with federal law including the Truth in Caller ID Act and TRACED Act, and explicitly does not impose strict liability for spoofed traffic merely transiting a provider's network
