Summary

The Twentieth Amendment, ratified in 1933, is often called the “Lame Duck Amendment.”
It shortened the period between election and inauguration, moving the start of congressional and presidential terms
to January rather than March — a reform born from the inefficiencies of a slower, pre-industrial era.

Before its adoption, outgoing officials often lingered in office for months after being replaced by the voters’ will,
a delay that risked stagnation and mismanagement in moments of crisis.
The amendment brought the machinery of democracy into closer rhythm with the voice of the people,
ensuring that leadership transitions occurred swiftly and responsibly.

It also clarified the line of presidential succession should the President-elect die or fail to qualify before taking office —
a safeguard of continuity in the Republic’s highest command.

Text of the Amendment

Section 1.
The terms of the President and Vice President shall end at noon on the 20th day of January,
and the terms of Senators and Representatives at noon on the 3d day of January,
of the years in which such terms would have ended if this article had not been ratified;
and the terms of their successors shall then begin.

Section 2.
The Congress shall assemble at least once in every year,
and such meeting shall begin at noon on the 3d day of January,
unless they shall by law appoint a different day.

Section 3.
If, at the time fixed for the beginning of the term of the President,
the President elect shall have died, the Vice President elect shall become President.
If a President shall not have been chosen before the time fixed for the beginning of his term,
or if the President elect shall have failed to qualify,
then the Vice President elect shall act as President until a President shall have qualified;
and the Congress may by law provide for the case wherein neither a President elect
nor a Vice President elect shall have qualified, declaring who shall then act as President,
or the manner in which one who is to act shall be selected,
and such person shall act accordingly until a President or Vice President shall have qualified.

Section 4.
The Congress may by law provide for the case of the death of any of the persons
from whom the House of Representatives may choose a President whenever the right of choice shall have devolved upon them,
and for the case of the death of any of the persons from whom the Senate may choose a Vice President
whenever the right of choice shall have devolved upon them.

Section 5.
Sections 1 and 2 shall take effect on the 15th day of October following the ratification of this article.

Section 6.
This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution
by the legislatures of three-fourths of the several States within seven years from the date of its submission.

“Amendment XX refined the rhythm of the Republic —
proving that even the march of liberty requires its calendar to keep pace with the conscience of the people.”
