What is Preemption?
Congress can expressly reserve an entire area of law for federal regulation. In such a case, the federal law preempts state law.
Generally, the state and federal governments may regulate the same type of conduct. This is known as concurrent power.
However, any state law that prevents or interferes with the accomplishment and execution of the full purposes and objectives of Congress is invalid.
If Congress does not expressly reserve the area of law for federal regulation, the state may also regulate it.
What is the Federal Court's Authority to Review State Laws?
State appellate courts or the US Supreme Court may review a state law and overturn it if it determines that the law conflicts with or violates a federal law.
- Note: Generally the state law can be more restrictive than the federal securities law.
- Example: The Federal Government regulates the immigration process. It expressly preempts states regulating this area of law. The Federal Government also regulates the purchase and sale of securities. States are not preempted from regulating the purchase or sale of securities, but a state law may not conflict with or prohibit the accomplishment of federal law.

Can you think of any recent state laws that were struck down because they conflicted with federal law? Can you think of any areas of law that are regulated by both state and federal law?
- An example of a State law that was struck down because it conflicts with federal law is seen in a case where a Maryland statute that required an importer to obtain a license before reselling in the original package articles imported from abroad . The law was struck down for being in conflict with the federal power to regulate foreign commerce (Art 1, s 8 cl 3) and with the constitutional provision (Art 1 s 10, cl 12) prohibiting States from levying import duties. Asbestos is regulated by both federal and state law. Asbestos has been known to cause conditions such as mesothelioma for many years. As a result, there has been an immense legal history involving the Asbestos materials, as well as many laws and materials that have emerged to control and limit Asbestos exposure. This is the reason why federal law and States law govern Asbestos
The Federal Government passes a statute that regulates certain business practices. Specifically, it requires businesses to seek federal approval through a licensing process. The law does not include a provision that specifically prohibits states from also regulating this conduct. Arizona determines that it wants to regulate this same activity by states within its borders. So, it passes a state statute that requires businesses to also seek a state license prior to undertaking the cover practice. Is this permissible? What if the state is far more stringent than the federal statute? Less stringent? Can the state require that a state license issue before a business may apply for a federal license?
- Federal law regulates businesses across state lines or even multiple countries. States law regulates business activities within its States like employment, insurance, and many others while federal law regulates business like the tax code, employment, and labor, antitrust law, etc. On the issue of whether the state can require that a state license be issued before a business can apply for a federal license, it is likely permissible for the state to pass such a statute that requires a business also to seek a state license prior to undertaking the cover practice. Since the law does not prohibit state law from regulating businesses, it means the state can offer business licensing to small businesses within the state and not outside its state. Business activities take place in a certain state; it is, therefore, possible for the state to require that they licensed business before the federal Government Issue their own license to businesses.
