History
The oldest NSL provisions were created in 1978 as a little-used method of circumventing the Right to Financial Privacy Act. Used in terrorism and espionage investigations, it was limited to foreign powers or persons who the FBI had reasonable cause to believe were agents of a foreign power. Compliance was voluntary, and states' consumer privacy laws often allowed institutions to decline these requests.[citation needed]
In 1986, the Act was amended to compel disclosure, and the Electronic Communications Privacy Act was created with similar provisions in place. Still, neither act identified any penalties for failing to comply with the letter.
A 1993 amendment relaxed the restriction regarding "foreign powers" and allowed the use of an NSL to obtain information on persons not under direct investigation.
In 2001, section 505 of the USA PATRIOT Act greatly expanded the use of the NSL. See below.
