A commerce power held by both state and federal governments is often referred to as concurrent powers. One example of such a commerce power is the ability to regulate the sale of goods and services within their respective jurisdictions. Both the federal government and state governments can enact laws and regulations pertaining to commerce, such as taxation on sales, regulation of businesses and trade practices, and enforcement of consumer protection laws.
While the federal government has the authority to regulate interstate commerce (commerce between states), states have the power to regulate intrastate commerce (commerce within their own borders). This overlapping authority allows both levels of government to play a role in managing economic activities.
