The federal government for years has claimed expansive powers under the authority to regulate commerce - so much, that the most innocent private activity can now come under federal control simply because it might have an influence on “interstate commerce.” Our system of government has become so dysfunctional and judicially corrupt that today Congress could simply outlaw liquor and thereby prohibiting its sale without the fuss of having to amend the Constitution all over again in the name of regulating commerce.
The Commerce Clause deals solely with exchanges of trade between Nations or States, which in return has absolutely nothing to do with regulating internal industries, labor or transactions. Regulating trade with another country has never been construed to mean to make and enforce laws that regulate the internal industries or labor of that country under the ruse such activity might have an effect on commerce with the United States.
As Thomas Jefferson put it: “To make a thing which may be bought and sold is not to prescribe regulations for buying and selling. Besides, if this were an exercise of the power of regulating commerce, it would be void, as extending as much to the internal commerce of every state, as to its external.”
The word “commerce” was always understood to mean the “exchange of commodities” through imports or exports, or simply, trade between different governments, which made regulating the slave trade awkward because it would have required treating human beings as commodities. Records of the constitutional convention shows James Madison felt it was “wrong to admit in the Constitution the idea that there could be property in men. The reason of duties did not hold, as slaves are not like merchandise, consumed &c.” This prompt a separate clause that specifically dealt with the foreign importation of slaves - not domestic trade.
The term “to regulate commerce” had a very definite and well-understood meaning before and after the American Revolution. The phrase had become popularized by disputes between the Colonies and England, as well with the Colonies themselves. It was never understood to embrace any of the offices between ship and shore, such as pilotage, wharfage, quarantine, etc., all of which were regulated by colonial law and not by the laws of England. It was also not understood to embrace the right to levy duties for revenue, upon either persons or articles, which explains why there are separate provisions in the Constitution for revenue.
Note that Article 1, Sec. 9 clearly distinguishes between the “regulation of commerce” and revenue.
The power to regulate commerce was, in the full sense of the meaning of the term and usage of the day, meant the right to impose a tariff on articles of imports in order to protect domestic manufactures or encourage manufactures. President James Monroe re-affirmed this understanding in 1822:
Commerce between independent powers or communities is universally regulated by duties and imposts. It was so regulated by the States before the adoption of this Constitution, equally in respect to each other and to foreign powers. The goods and vessels employed in the trade are the only subjects of regulation. It can act on none other.
Monroe’s explanation of regulating commerce makes it easy to understand why the Constitution speaks only of the method of laying duties, imposts or of vessel tonnage instead of legislative authority over industries. During the August 1787 convention, Madison noted that Col. Mason observed the “particular slates might wish to encourage, by impost duties, certain manufactures, for which they enjoyed natural advantages, as Virginia [in] the manufacture of hemp, &.c.”
Madison responded by saying the “encouragement of manufactures in that mode requires duties, not only on imports directly from foreign countries, but from the other states in the Union, which would revive all the mischiefs experienced from the want of a general government over commerce.”
Oliver Ellsworth during the convention clearly stated the object of the language: “It is best as it stands—The power of regulating trade between the States will protect them agst each other—Should this not be the case, the attempts of one to tax the produce of another passing through its hands, will force a direct exportation and defeat themselves.”
In Federalist No. 42, Madison explains the objective behind the regulation of commerce among the States as to prevent the laying of duties on other States imports and exports:
A very material object of this power was the relief of the States which import and export through other States, from the improper contributions levied on them by the latter. Were these at liberty to regulate the trade between State and State, it must be foreseen that ways would be found out, to load the articles of import and export, during the passage through their jurisdiction, with duties which would fall on the makers of the latter, and the consumers of the former. We may be assured by past experience, that such a practice would be introduced by future contrivances; and both by that and a common knowledge of human affairs, that it would nourish unceasing animosities, and not improbably terminate in serious interruptions of the public tranquility.
James Wilson said to deny the common Government the power to tax the exports of the States would remove “half the regulation of trade.” Delegate John Langdon insisted the regulation of tonnage through duties “was an essential part of the regulation of trade.” In an 1827 letter to Joseph Carrington Cabell, Madison explained the meaning of the words this way:
The meaning of the power to regulate commerce is to be sought in the general use of the phrase; in other words, in objects generally understood to be embraced by the power when it was inserted in the Constitution.
The objects embraced by the power was that “no state be at liberty to impose duties on any goods, wares, or merchandise, imported, by land or by water, from any other state, but may altogether prohibit the importation from any state of any particular species or description of goods, wares, or merchandise, of which the importation is at the same time prohibited from all other places whatsoever.” [Madison’s resolution for empowering Congress to regulate trade, November 30, 1785]
James Madison draws attention to Connecticut’s levying of duties on other Colonies imports/exports but not foreign nations in an 1832 letter to Professor Davis of the University of Virginia:
The power to regulate commerce among the States was well known and so explained by the advocates of the Constitution when before the people for their consideration, to be as a necessary control on the conduct of some of the importing States toward their non-importing neighbors. A recurrence to the angry legislation produced by it among the parties, some of whom had passed commercial laws (tariff’s) more rigid against others than against foreign nations, will well account for the constitutional remedy.
Mr. Madison said it was “very certain” that the power to regulate commerce among the States “grew out of the abuse of the power by the importing States in taxing the non-importing, and was intended as a negative and preventive provision against injustice among the States themselves, rather than as a power to be used for the positive purposes of the General Government, in which alone, however, the remedial power could be lodged.”
How could the regulation of commerce among the states be considered a “negative and preventive provision” as well as not any “power to be used for the positive purposes” of the general government? The answer is simple under Article I, Section 10 of the Constitution where the States are directly prohibited “without the Consent of the Congress, lay any Imposts or Duties on Imports or Exports, except what may be absolutely necessary for executing it’s inspection Laws.” Additionally, Congress is forbidden to tax the exports of a State, give preferences to ports where vessels “enter, clear, or pay duties in another.”
If both the colonies and the text of the clause intended to give Congress exclusive legislative powers over all internal matters of trade between the States, then one must ask how is “to regulate commerce” different between foreign nations and among the States? In other words, if Congress can make laws for buying and selling under the clause, could they also impose laws with on buying and selling within other countries? Of course the regulation of commerce could not accomplish that, but the imposing of duties on imports of goods from other countries once arriving here could.
Joseph Story said if such expansive powers under the power to regulate commerce could be exercised, then it would be a demolition of all constitutional boundaries:
The question comes to this, whether a power, exclusively for the regulation of commerce, is a power for the regulation of manufactures? The statement of such a question would seem to involve its own answer. Can a power, granted for one purpose, be transferred to another? If it can, where is the limitation in the constitution? Are not commerce and manufactures as distinct, as commerce and agriculture? If they are, how can a power to regulate one arise from a power to regulate the other?
It is true, that commerce and manufactures are, or may be, intimately connected with each other. A regulation of one may injuriously or beneficially affect the other. But that is not the point in controversy. It is, whether congress has a right to regulate that, which is not committed to it, under a power, which is committed to it, simply because there is, or may be an intimate connexion between the powers…
If this were admitted, the enumeration of the powers of congress would be wholly unnecessary and nugatory. Agriculture, colonies, capital, machinery, the ages of labour, the profits of stock, the rents of land, the punctual performance of contracts, and the diffusion of knowledge would all be within the scope of the power; for all of them bear an intimate relation to commerce. The result would be, that the powers of congress would embrace the widest extent of legislative functions, to the utter demolition of all constitutional boundaries between the state and national governments.
What about navigation? Nothing had changed in regards to navigation between the old and new Constitution. Under the old Articles of Confederation, Congress had no jurisdiction over transportation from State to State save as conducted by coasting navigation. Interstate transportation was left to the States and Congress was just as forbidden then as they are today to tax articles exported from any State.
Charles Pinckney, a man who would know what he is talking about on this subject since he was involved in the framing of the Constitution, sums up the entire issue with this statement in the House of Representatives on February 14, 1820:
I will only mention here, as it is perfectly within my recollection, that the power was given to Congress to regulate the commerce by water between the States, and it being feared, by the Southern, that the Eastern would, whenever they could, do so to the disadvantage of the Southern States (impose tariff’s), you will find, in the 6th section of the 1st article, Congress are prevented from taxing exports, or giving preference to the ports of one State over another, or obliging vessels bound from one State to clear, enter, or pay duties in another; which restrictions, more clearly than any thing else, prove what the power to regulate commerce among the several States means.
Pinckney simply points out that the restrictions placed upon Congress effectively nullifies the regulation of commerce between the States. Also, Pinckney brings up a very important point that defines the power to regulate commerce among the States that many ignore: The very purpose sought from the insertion of the words. Moreover, the answer to this question has always been without controversy to prevent one State from laying imposts or duties on another States imports as it transits through its limits.
In other words, it was inserted as a preventive measure and never as any kind of authoritative power.
Finally, the truth behind what the regulation of commerce means can easily be discovered by how the colonies and other nations regulated their commerce with each other. The truth will be uncomfortable, even embarrassing under current commerce precedent but truth will always be more rewarding than judicial fiction.

Ignoring this truism has indeed caused nothing but conflicts between competing sovereignties. This alone should tell justices their commerce jurisprudence is false.
“The Commerce Clause deals solely with exchanges of trade between Nations or States, which in return has absolutely nothing to do with regulating internal industries, labor or transactions. Regulating trade with another country has never been construed to mean to make and enforce laws that regulate the internal industries or labor of that country under the ruse such activity might have an effect on commerce with the United States.”
That is an absolute truth that needs no Supreme Court ruling to vindicate.
I find the language within the constitution and its history and the framers explanation of regulating commerce far more persuasive then the courts. The courts current precedent is something you would expect from lawless tyrants.
If I understand this correctly the decision in POLAR TANKERS, INC. v. CITY OF VALDEZ, ALASKA was not correct. Valdez was not taxing the tonnage of trade belonging to any state or foreign country, but taxing the dry weight of the ship.
In Reply to Lloyd Benedict:
Technically per strict meaning and operation of the words as employed by the framers, there is nothing for the Feds to regulate under the commerce clause between the states.
The states have always imposed duties on those goods imported whose final designation was the state imposing the tax/duties. They are only prevented from imposing duties on other states imports as those imports pass through.
Hi, great article. I work with hundreds of wineries in the US and many of these people cant ship directly to residents in some states simply because the license and taxes to pay the destination state are ridiculously high. I ‘feel’ this is unconstitutional because these business owners produce a federally regulated good that is licensed at the Federal level, however states are preventing wineries the ability to sell across state lines. Is there any fact to my ‘feeling?’
I’m guessing you libertarian, lol?
It is a fantastic article. I have been researching Constitutional issues myself, and aside from Madison’s notes, Jonathan Elliot’s notes are also extremely helpful, in understanding the original intent of the constitution.
Good work!
I am going to nominate this commerce clause treatise as the greatest ever written.
It’s really funny how some Americans always complain that they have so little freedom while actually living in the most free country in the world. It is even more funny that you expect a 200-years old document to guide government behavior even today. After all it was written for a very different country. Unregulated commerce is not viable because it would run out of political support very fast and that would result in general unrest and instability.
It’s just like the free trade. We have to impose some limitations on it and talk bad about it just so that it can continue to exist. If politicians stop appeasing the protectionist feelings of the public and stop pretending that they’re against outsourcing american jobs, the public might take the matters into its own hands and then we will see a crisis that will dwarf the Great Depression.
I don’t think there is anything “obscure” about the clause, Edlfwood.
It is only obscure if you read it as only saying “To regulate Commerce among the several States,” ignoring the rest of the clause and all other articles under the Constitution.
The framers made a big mistake leaving this clause 1-8-3 so obscure, the misinterpretation of 1-8-3 has cost us all but whats left of our freedoms. The Supreme Court is a political puppet now and it may be time for another revolution, an intellectual one. Great, great article love the quotes to support the argument and agree. Down with 1-8-3!
“Mr. Madison also explained the regulation of commerce among the States was strictly “a negative and preventive provision against injustice among the States themselves, rather than as a power to be used for the positive purposes of the General Government.” “
The hidden tax on Americans aka tax abatements, tax incentives, in my opinion violates the sprirt of free commerce between the states. Government entities sell out their constituants in order to attrack business to town in the form of tax abatements, etc. There is no reason to lure big box retailers, involved in interstate commerece, to locales where they are going to make money. Some thing must regulate these actions which can in some cases give one retailer and unfair advantage over another.
The trouble with regulating corporations is that the corporations control the government…catch 22
Those comments by J. Madison that commerce among the states is a “negative and preventive provision” and served as no “positive purposes of the General Government” is damaging as hell to the credibility of the court.
I would had never accepted this argument prior to reading this. It must be true else as Paul Madison points out, section ten would had directly disabled the states if a positive influence by the federal govt. over commerce was really the purpose of the language.
Gawd, I can’t believe how incompetent the supreme court really is.
This is one helluva analysis.
I really like the final results of this post. What took so long?
I always had this feeling deep inside the commerce clause was by all intents very limited because of the other limitations placed on congress. This post confirms my suspicions and as a bonus, brings harmony to the other powers/limits of congress AND THE STATES… something the supreme court never seemed able to accomplish.
This is the most magnificent explanation of the meaning to regulate commerce I have ever read, and I have read many.
