One reason some people fail to understand why the State of Texas can protect itself against the illegal immigration invasion is that they lose sight of a basic part of American constitutional federalism. This is the distinction between exclusive powers and concurrent powers.
When I was teaching law-school constitutional law courses, I found that many of my students had trouble with this distinction. And when a hot topic such as immigration triggers your political passions, it can be hard to think straight about any subject, especially a point of law.
Indeed, when political passions rage, even experienced lawyers and judges can become confused.
The People Granted Powers through the Constitution
Before the Constitution was ratified, the 13 “united States” were independent countries in a treaty of alliance called the Articles of Confederation. (In 18th-century English, the term “confederation” meant merely an international alliance or league.) Each state retained sovereignty, limited only by a few grants to Congress.And to prevent future doubt on that point, Congress proposed and the states ratified the Ninth and 10th Amendments.
The Constitution’s Arrangement
Much of the Constitution’s structure follows a pattern common in 18th-century agreements by which “principals” granted enumerated (listed) powers to “agents.”Exclusive and Concurrent Powers
If the Constitution does not grant the federal government authority over a subject, then authority over that subject remains entirely in the states. This is called exclusive state jurisdiction. For example, only states may fix the terms of office for state officials or construct local streets.- Congress has exclusive power over the District of Columbia (Article I, Section 8, Clause 17).
- The U.S. House of Representatives has the “sole Power” of impeaching federal officials (Article I, Section 2, Clause 5) and the Senate the “sole Power” of trying them (Article I, Section 3, Clause 6).
- Besides granting the federal government wide foreign policy and financial powers, the Constitution denies the states certain specific foreign policy and financial powers. For example, only the federal government may make treaties with foreign nations or issue bills of credit (a kind of paper money) (Article I, Section 10, Clause 1).
But—and this is critical to our discussion—in the vast majority of areas where the Constitution grants powers to the federal government, the states still retain authority to act. These are subjects over which federal and state governments have concurrent jurisdiction. They include commerce across political borders; creating and administering courts; imposing trade embargoes against foreign powers; building post roads (intercity highways); governing the militia; and taxing and borrowing.
For a state to have a concurrent power, there is no need for the Constitution to recognize it explicitly; the Ninth and 10th Amendments are sufficient. Yet in some cases, the document does include explicit recognition. Two such cases are the state’s authority to resist invasion (Article I, Section 10, Clause 3) and to control migration across state borders (Article I, Section 9, Clause 1).
The Mistake People Make
On such points, the Constitution and its history are quite clear. Nevertheless, promoters of centralized governance have long tried to muscle out state officials by expanding concurrent federal power into exclusive federal power.Similarly, Congress’s power to “regulate Commerce with ... the Indian tribes” (Article I, Section 8, Clause 3) leaves states with a fair amount of authority over Indian affairs. Yet some commentators and jurists contend that it grants the feds exclusive power over the subject.
Confusion Over Immigration and Invasion Powers
Confusion over exclusive and concurrent jurisdiction is rife in the current illegal immigration–invasion crisis and particularly in the litigation between Texas and the federal government. In a March 19 dissenting opinion, Justice Sonia Sotomayor claimed that the “authority to control immigration—to admit or exclude [noncitizens]—is vested solely in the Federal Government.” However, this proposition is contradicted both by the Constitution’s structure and by the wording of Article I, Section 9, Clause 1.Actually, however, the “strong evidence” is to the contrary: It is highly doubtful that Congress could, by statute, destroy a state by denying it the right of self-defense. In fact, the Constitution’s Guarantee Clause (Article IV, Section 4) and some of the 1787–90 debates suggest the exact opposite.
