What Is Preemption? How Does It Affect Public Health?

A Public Health Law Academy video short

Good Governance

How does a higher level of government (like federal or state government) limit or even eliminate the powers of lower levels of government (like state or local government)? What are the implications for public health laws? Understanding the legal concept of preemption can help public health practitioners advance community-driven policymaking and health equity.

What Is Preemption? How Does It Affect Public Health? is a short video that explains how preemption prevents state or local governments from passing laws that govern certain issue areas. The video covers the different types of preemption and describes how preemption can be either express (explicit) or implied, depending on the wording of the written law. 

This video includes material from the Public Health Law Academy's full-length training Preemption & Public Health. The video is intended for public health practitioners who want a quick, high-level introduction to preemption. It can also be used by trainers or faculty who want to introduce the concept in a classroom or a training workshop.
