Preamble
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
In plain language: The Preamble states the Constitution's purposes. It introduces the document but does not itself grant a specific power.
Article I, Section 1
All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.
In plain language: Congress makes federal law. Its powers are those granted by the Constitution, subject to constitutional limits.
Article III, Section 2 (excerpt)
The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority.
In plain language: Federal courts decide cases within the jurisdiction described by the Constitution and federal statutes.
Article VI (Supremacy Clause excerpt)
This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land.
In plain language: Valid federal law takes priority over conflicting state law. Whether a law is valid and preempts another can depend on the specific text and case law.
First Amendment (excerpt)
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
In plain language: The First Amendment protects several freedoms from government restriction, subject to doctrines developed by courts.
Fourth Amendment (excerpt)
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.
In plain language: The Fourth Amendment limits unreasonable government searches and seizures. Warrant rules and exceptions are fact-specific.
Fifth Amendment (excerpt)
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury ... nor be deprived of life, liberty, or property, without due process of law.
In plain language: Among other protections, the Fifth Amendment includes grand-jury provisions for certain federal prosecutions and a due-process guarantee.
Sixth Amendment (excerpt)
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury ... and to have the Assistance of Counsel for his defence.
In plain language: The Sixth Amendment provides procedural rights to people accused of crimes, including counsel and a public, speedy trial.
Fourteenth Amendment, Section 1 (excerpt)
No State shall ... deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
In plain language: The Fourteenth Amendment applies due-process and equal-protection requirements to state governments. Its application depends on the legal issue and precedent.
