The doctrine of selective exclusiveness maintains that states can regulate interstate commerce in which of the following cases?
When national security demands it
When federal laws are absent
Whenever they desire
When it concerns to the wellbeing of their citizens
The Correct Answer and Explanation is:
Correct Answer: When federal laws are absent
Explanation (300+ words):
The doctrine of selective exclusiveness, also known as cooperative federalism in some contexts, originates from the U.S. Supreme Court’s interpretation of the Commerce Clause of the Constitution. This clause grants Congress the exclusive power to regulate interstate commerce (Article I, Section 8, Clause 3). However, the doctrine of selective exclusiveness provides a nuanced view of this federal authority and outlines when states may step in to regulate interstate commerce.
This principle was articulated in the landmark case Cooley v. Board of Wardens (1852). The Supreme Court ruled that while Congress has broad power over interstate commerce, not all areas of commerce require national, uniform regulation. Therefore, in the absence of federal legislation, individual states may regulate aspects of interstate commerce, provided that the regulation does not interfere with federal law or place an undue burden on interstate trade.
This doctrine supports a dual-sovereignty approach—recognizing both federal and state authority—but gives preference to federal power when it is exercised. However, if Congress has not enacted a law in a particular area of interstate commerce, states can regulate it, especially when the matter is localized and does not require national uniformity.
Let’s analyze the choices:
- “When national security demands it” – While important, national security falls more under federal jurisdiction, particularly the executive and legislative branches, not this doctrine.
- “When federal laws are absent” – ✅ Correct. This is the essence of the doctrine: states may regulate only when federal regulation is not present and when uniformity is not essential.
- “Whenever they desire” – ❌ Incorrect. States cannot regulate interstate commerce at will due to the Supremacy Clause and Commerce Clause.
- “When it concerns the wellbeing of their citizens” – ❌ While states can regulate for public health and safety, they cannot do so if it interferes with interstate commerce regulated by the federal government.
Thus, states may regulate interstate commerce only in the absence of federal laws, consistent with the doctrine of selective exclusiveness.
