Part 4 of John's CIPP/US Privacy MaterialsJohn Bandler’s CIPP/US and US Privacy Learning Part 4

Laws on Government and Court Access to Private-sector Information, BoK III

by John Bandler

This is Part 4 of my U.S. Privacy and CIPP/US and privacy learning materials (aligning with CIPP/US BoK Domain III).

+ This page is greatly updated and mostly comprehensive after a recent revamp in August 2026. +

1. To navigate John's CIPP/US pages

2. Topics covered

Here we cover cover issues relating to privacy from government, including law enforcement and national security roles. We should think about how government gets information or data that it needs, and the CIPP/US focus is how it gets data stored by third parties. We also examine the role of the civil courts to compel the exchange of data.

But to get there, we need to understand some basics on law and the Fourth Amendment, which we will recap (having covered it a little in earlier domains). We will cover the Electronic Communications Privacy Act (ECPA), the Foreign Intelligence Surveillance Act (FISA), and more.

This domain is not highly tested but is important to know, especially if you live in the U.S. This domain essentially covers:

  • Law Enforcement and Privacy
    • Electronic Communications Privacy Act (ECPA)
    • Wiretap Act
    • Stored Communications Act (SCA)
    • Pen Register Trap and Trace Devices
    • The Communications Assistance to Law Enforcement Act (CALEA)
    • Privacy Protection Act of 1980
  • National Security and Privacy
    • Foreign Intelligence Surveillance Act of 1978 (FISA)
    • USA-PATRIOT Act: Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001
    • The USA Freedom Act of 2015
    • The Cybersecurity Information Sharing Act of 2015 (CISA)
  • Civil Litigation and Privacy
    • Discovery / Disclosure
    • E-discovery

We see many issues relating to this in the news almost daily.

By now we have a solid foundation in law and U.S. government which helps us as we navigate the issues relating to the U.S. Constitution and Fourth Amendment, separation of powers and checks and balances, and balancing various needs.

Law enforcement needs the ability to investigate and arrest, but it is limited by the Fourth Amendment. Our national security apparatus needs the ability to spy and counterspy, but that also needs limits. Then, a lawsuit between parties means each side needs information to prepare for trial (known as discovery or disclosure) but that can have privacy implications.

In 2026 the federal government started misstating the law about what it took to arrest an individual, and when a home can be searched. I created a video on the Fourth Amendment to try share some legal knowledge with others.

3. Don't forget the overall references for CIPP/US and my courses

  • See my Part 1 webpage for the overall references and additional reading (including IAPP resources)
  • My online courses provide priority coverage of important areas, so if you are in my online course, listen to those first.
  • If you are taking one of my online courses and want to dig deeper into the materials, I provide resources and references here. Prioritize your time, start by learning the basics before digging into the weeds.
  • If you are not taking one of my online courses, that's OK too, I hope they help you, and please consider this.

4. Part 4 specific references

  • See my Part 1 course for the overall references and additional reading (including IAPP resources, the coursebook, etc.)
  • My courses provide priority coverage of important areas. If you want to dig deeper (or are not taking one of my courses) see these resources.

Part 4 prioritization: As always, start with the basics. This part is not heavily tested but it is important for life and being in the U.S. and is in the news a lot.  Part 4 is close to my heart, and I have spent a lot of time in it, so keep that in mind as you review the below, so you can prioritize your time. Keep your focus on the solid basics, don't get too far into the details or my additional references or resources.
