Article 1, Section 4 of the Constitution does two jobs. It sets the ground rules for who regulates federal elections, giving state legislatures the default authority while letting Congress step in and override them. And it requires Congress to meet at least once a year so the legislative branch cannot be shut down by a president or blocked by inaction. The election half of the section is known as the Elections Clause; the meeting half is the Assembly Clause, and its December meeting date has since been replaced by the 20th Amendment’s January 3 start.
What the Section Actually Says
Clause 1, the Elections Clause: “The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.”
Clause 2, the Assembly Clause: “The Congress shall assemble at least once in every Year, and such Meeting shall be on the first Monday in December, unless they shall by Law appoint a different Day.”1Congress.gov. Article I Section 4
What States Get to Decide About Federal Elections
The Elections Clause puts state legislatures in charge of the everyday mechanics of federal elections. Each state decides when polls open, where voting takes place, and the procedures voters follow. A rural state with a handful of counties has different logistical problems than a state with millions of voters, and the framers recognized that local governments handle those details better than a central authority could.
The word “Manner” carries most of the weight in the clause. In Smiley v. Holm (1932), the Supreme Court read it to cover essentially the entire election process: voter registration, supervision of voting, fraud prevention, vote counting, the duties of election officials, and publication of results. The Court described the authority as power to create “a complete code for congressional elections.”2Legal Information Institute. Smiley v. Holm
Smiley also settled a second question: “Legislature” here means the state’s ordinary lawmaking process, not the legislative body acting alone. A governor can veto an election bill the same way any other bill can be vetoed, and voter-approved ballot initiatives can set election rules too. The clause doesn’t create a special channel that bypasses the rest of state government.
How Congress Can Override State Election Rules
The second half of the Elections Clause is a federal override switch. Congress can “at any time by Law make or alter” the regulations states have adopted for federal elections. The framers added this backup because they feared a state might refuse to hold elections at all, effectively withdrawing itself from the national government. Without a federal override, a handful of uncooperative states could have crippled the new republic.
The Supreme Court confirmed how broad this power runs in Ex parte Siebold (1879), holding that Congress can add new duties for election officials, impose penalties for fraud, and send federal officers to polling places. When federal rules conflict with state rules, federal law wins, because the power to “make or alter” includes the power to supersede.3Justia Law. Ex Parte Siebold, 100 US 371 (1879) Congress does not need to take over the whole election system to use this authority; it can change specific rules and leave the rest of a state’s framework in place.
A modern example is Arizona v. Inter Tribal Council of Arizona (2013). The Court struck down Arizona’s demand that federal voter registration applicants provide documentary proof of citizenship, holding that when the National Voter Registration Act told states to “accept and use” a standardized federal registration form, that command preempted Arizona’s extra requirement.4Justia Law. Arizona v. Inter Tribal Council of Arizona Inc., 570 US 1 (2013)
Federal Laws Passed Under This Power
Congress has used the Elections Clause repeatedly. Most of these laws are still in effect.
A Single Election Day and Single-Member Districts
Federal law sets one national election day: the Tuesday after the first Monday in November in every even-numbered year.5Office of the Law Revision Counsel. 2 USC 7 – Time of Election Before the uniform date was imposed in 1872, states voted on different days, and results in earlier states influenced voters in later ones. Congress had also acted in 1842 to require that House members be elected from single-member districts rather than at-large, and that rule remains in force.6United States Census Bureau. Apportionment Legislation 1840-1880 Later apportionment acts added contiguity and rough population-equality requirements, partly as early anti-gerrymandering measures.
The National Voter Registration Act
The National Voter Registration Act of 1993, known as the motor voter law, requires states to offer registration at motor vehicle offices, public assistance agencies, and disability services offices, and to accept a standard federal mail-in registration form.7Department of Justice. The National Voter Registration Act of 1993 It applies to 44 states and the District of Columbia; six states with Election Day registration or no registration requirement are exempt. The Act also regulates how states clean up voter rolls, with a 90-day “quiet period” before a federal primary or general election during which bulk removals are barred.8United States Department of Justice.

The Help America Vote Act
After the contested 2000 presidential election exposed problems with outdated equipment, Congress passed the Help America Vote Act in 2002. HAVA set minimum standards for election administration, funded voting-system upgrades, and guaranteed provisional ballots for voters whose eligibility is in question at the polls.9U.S. Election Assistance Commission. Help America Vote Act If your name doesn’t appear on the rolls at your polling place, officials must let you cast a provisional ballot and give you a way to check afterward whether it was counted.10Office of the Law Revision Counsel. 52 USC 21082 – Provisional Voting and Voting Information Requirements
The Carve-Out for Places of Choosing Senators
The Elections Clause has one exception: Congress can override state rules on the times and manner of elections, but not “the Places of chusing Senators.” That exception made sense under the original design, where state legislatures picked senators rather than voters. Article 1, Section 3 originally provided that the Senate would be “composed of two Senators from each State, chosen by the Legislature thereof.”11Constitution Annotated. Article I Section 3 – Senate The framers worried Congress could otherwise harass state legislatures by forcing them to convene in inconvenient places to pick senators.
The 17th Amendment, ratified in 1913, largely made the exception a relic. By requiring that senators be “elected by the people thereof,” it moved Senate elections from statehouse floors to ordinary polling places.12U.S. Senate. Landmark Legislation: The Seventeenth Amendment to the Constitution The clause is still in the constitutional text, but it no longer functions as a meaningful limit on federal power.
Do State Legislatures Answer to State Courts?
A major constitutional dispute over the Elections Clause reached the Supreme Court in Moore v. Harper (2023). The “independent state legislature theory” argued that the phrase “Legislature thereof” gives state legislatures exclusive, unchecked authority over federal election rules, free from state courts or state constitutional constraints. If accepted, state courts could not have struck down gerrymandered maps or other election laws under state constitutional rights.
The Court rejected the theory. It held that the Elections Clause “does not vest exclusive and independent authority in state legislatures to set the rules regarding federal elections,” and that state legislatures remain subject to state judicial review when they write election laws.13Justia Law. Moore v. Harper, 600 US ___ (2023) The Court noted that federal courts could intervene if a state court dramatically overstepped the ordinary bounds of judicial review, but said such federal review should be deferential and rare.
Partisan Gerrymandering and Where the Fight Sits Now
In Rucho v. Common Cause (2019), the Supreme Court ruled that federal courts cannot hear challenges to partisan gerrymanders, because they present political questions without manageable judicial standards. The Court pointed out that the Elections Clause gives Congress the authority to act, and Congress has used that authority before: the single-member district requirement and the historical compactness standards were both enacted under this clause.14Supreme Court of the United States. Rucho v. Common Cause, No. 18-422 (2019) Whether Congress will pass new anti-gerrymandering legislation is a political question, not a judicial one.
The Annual Meeting Requirement
Clause 2 required Congress to meet at least once each year. The framers had a specific fear in mind. Under British rule, the king could prorogue Parliament and prevent it from assembling, and several colonial governors had done the same to local legislatures. Writing a mandatory annual session into the Constitution guaranteed that no president could suspend Congress or leave the country without a working legislature.1Congress.gov. Article I Section 4
The original default date was the first Monday in December, with Congress free to pick a different day by law. That December start created a lasting structural problem: members elected in November would not take office until the following March, and the new Congress’s regular session would not begin until December, more than 13 months after Election Day. Meanwhile, the outgoing “lame duck” Congress kept voting from November through March, defeated members included.15U.S. House of Representatives. The Twentieth Amendment
The 20th Amendment, ratified in 1933, fixed this by moving the start of each new Congress to noon on January 3.16Congress.gov. Twentieth Amendment Newly elected members now take their seats about two months after the election. Congress kept its flexibility to choose a different day by law, but January 3 has been the default in every modern Congress.
