As the federal government pursues a deregulatory agenda, state regulators are increasing their enforcement activities to fill perceived gaps in oversight. They pursue their own regulatory agendas under state regulatory regimes that are often less developed than similar federal laws. This lack of existing state-level precedent opens the door for states to employ novel and aggressive legal theories that increase risk and uncertainty for private actors. Businesses should respond by evaluating opportunities to leverage the more comprehensive body of federal law as persuasive authority for previously unresolved questions of state law.
