US Constitution

The same ban, printed twice

Article I forbids bills of attainder and ex post facto laws in Section 9. Section 10 forbids them again, in almost the same words. That is not sloppy drafting. Section 9 lists what Congress may not do, and Section 10 lists what the states may not do, so the two paragraphs restrain two different governments. Land on the wrong one in a brief and you have told the court the wrong thing about who is bound.

Nothing on the page says any of that. The Constitution carries no index and no headings, and a Section number announces nothing about its subject. What organizes the document is the order the framers put things in, and that order is the only guide you get. Learn it and you find a provision in seconds. Skip it and every search is a scroll through the text (opens in a new tab), hoping something looks familiar. The activity drills the finding, ten rounds against a senior paralegal who will not hand you an answer. This reading is the map that drill assumes you already have.

One sentence of purpose, then seven Articles of machinery

The Preamble is a single sentence, and it is the only place the document states a purpose for itself. It names who is acting, the People of the United States, and what they mean to accomplish. What it does not do is grant anyone power. The distinction shows up in practice: a brief can open on the Preamble to frame what the document is for, and it cannot rest a claim of authority there. The authority is always somewhere in the Articles.

Then the machinery. The seven Articles run in an order that shows what the framers were most worried about. Article I creates Congress and runs to ten Sections. Article II creates the presidency in four. Article III creates the courts in three, and it is the shortest of the branch Articles by a wide margin. The lawmaking power comes first and takes the most text, and most of that text goes to hedging it.

Inside Article I the pattern repeats one level down. Section 8 lists the powers Congress has. Section 9 lists the powers it does not. Section 10 turns to the states and lists what they may not do. Powers, then limits on the grantee, then limits on the states. See that sequence once and you can predict where a rule about Congress lives before you go looking.

The back four Articles are short, and they are where students never think to look. Article IV governs how the states deal with one another: full faith and credit, interstate comity, new states and federal property, and the guarantee of a republican form of government. Article V sets out how the document is changed. Article VI carries the old debts, the supremacy of federal law, and the oath requirement. Article VII says that nine states ratifying is enough. Between them those four Articles hold several of the provisions the drill will ask you for.

A citation points at a paragraph

Look at the parchment and you will not find a clause number anywhere on it. The National Archives transcription (opens in a new tab) marks Articles and Sections, and inside a Section the provisions are paragraphs, one after another. The clauses lawyers cite are those paragraphs, counted. Clause 3 means the third paragraph of that Section. The numbering is an editorial convention that courts and publishers settled into, not something the framers wrote.

Convention or not, it is how the work gets done. Citing Article I, Section 8 tells a court that Congress has some power in the neighborhood. Citing Article I, Section 8, Clause 3 points at one line, the power “to regulate Commerce … among the several States.” That line is the commerce power, entire, and every fight over its reach is a fight about those words. Precision to the clause is what lets a reader check you.

The same counting reaches the provision students misplace most often. The Supremacy Clause is Article VI, Clause 2, the middle of that Article’s three paragraphs. It makes the Constitution, federal law, and treaties the supreme law of the land. Most people look for it in Article I, because Article I is where federal power seems to belong. It is not there. The paragraph right after it holds the oath requirement and the ban on religious tests for federal office, which is a provision readers hunt for in the First Amendment. Article VI runs three short paragraphs, and two of them are places nobody thinks to look.

Twenty-seven changes that sit apart from what they changed

Amendments arrive through the procedure in Article V, and the thing to understand about them is physical. An amendment does not edit the Articles. It is appended at the end, and the language it displaced stays on the page exactly as written in 1787.

So Article I, Section 3 still says the Senate is composed of two Senators from each State, “chosen by the Legislature thereof.” That stopped being the law in 1913, when the Seventeenth Amendment made senators elected by the people of each state. Article I, Section 2 still carries the rule that apportioned representatives by adding “three fifths of all other Persons” to the free population. The Fourteenth Amendment, Section 2 replaced it, apportioning instead by the whole number of persons in each state.

Read the Articles by themselves and you can come away holding a rule that has not been law for a century. The Constitution Annotated (opens in a new tab) marks the superseded passages, and the Archives transcription hyperlinks the changed text to the amendment that changed it. Use one of them. A clean copy of the original parchment is the wrong tool for finding out what the law is now.

The trap runs the other way too. The first ten amendments are the Bill of Rights, and most of the rights a student goes hunting for are there or in the Fourteenth. Not all of them. The guarantee of a jury in criminal cases is in the Sixth Amendment, and it is also in Article III, Section 2, Clause 3, which put it in the original document before any amendment existed.

What the drill is training

The activity runs ten rounds in one direction and at least six in the other. Forward, the drill names a power and you supply the address. In reverse, it names the address and you supply the power. Those are two different acts of memory, and being good at the first does not make you good at the second. Running both is how you find out.

Neither direction rewards a guess, because the drill sends you into the real text on every miss. That is the design working, not the drill being difficult. The provision you read after getting it wrong is the one you will remember, and half an hour of that beats an afternoon of reading the document straight through.

One caution for the debrief. The AI will tell you where provisions live and why they sit where they do, and it will be right most of the time. Most of the time is not good enough for a citation. Verify its locations against the Constitution Annotated (opens in a new tab) yourself. It is the check you would run on a junior colleague’s work, and the one somebody will eventually run on yours.

Start with Part 1. Read the orientation, then read the document start to finish at skim depth. Then open the Navigation Drill. Round 1 comes fast.
