What the question is asking: which constitution is meant

When and where the Constitution was written and ratified
The foundational work on the United States Constitution occurred at the Philadelphia Convention, where delegates met to revise the Articles of Confederation and instead drafted a new federal charter in 1787; the commonly cited signing date is September 17, 1787, and states completed ratification during 1788 National Archives transcription of the Constitution.
That drafting setting, often called the Philadelphia Convention, produced the short Preamble and seven Articles that formed the original text, and the National Archives provides the authoritative transcription historians and lawyers use when citing the document National Archives transcription of the Constitution.
Core structure: Preamble, Articles I to VII
The Constitution opens with a brief Preamble that states purposes such as to “form a more perfect Union” and then lays out seven Articles that organize the branches of federal government and assign powers National Archives transcription of the Constitution.

Articles IV through VII cover state relations, the process for adding amendments, federal supremacy, and procedures for ratification, together forming the structural backbone that modern constitutional interpretation builds on Legal Information Institute overview of the Constitution.
The Bill of Rights and the later Amendments

How the Constitution can be changed: Article V and amendment mechanics
Article V sets out two methods for proposing amendments and two for ratification, creating a two-step process that the states and Congress have used to produce all 27 amendments to date National Archives transcription of the Constitution.
One common route is proposal by two thirds of both houses of Congress followed by ratification by three quarters of the state legislatures or state conventions; a second route is a convention called by two thirds of state legislatures for proposing amendments, though that route has never produced an amendment to date Legal Information Institute overview of the Constitution.
The Article V procedure has produced amendments that change who may vote and how government operates, and the constitutional amendment process remains the formal path for durable structural change rather than rhetorical claims about what the Constitution says Legal Information Institute overview of the Constitution.
Judicial review and the role of the Supreme Court
The practice of judicial review, whereby courts assess whether laws are consistent with the Constitution, was established in practice by the Supreme Court in Marbury v. Madison in 1803 and has shaped how federal and state laws are enforced against constitutional limits Oyez summary of Marbury v. Madison.
Judicial review means that the meaning of the Constitution is applied by courts using the text, precedent, and interpretive methods; the Supreme Court often frames its decisions with reference to constitutional clauses and historical practice when determining whether a statute fits the Constitution Legal Information Institute overview of the Constitution.
Why the Preamble matters but is not a source of enforceable powers
The Preamble articulates goals and general purposes, with phrases such as to “form a more perfect Union” serving as interpretive context rather than a grants clause that confers specific powers National Archives transcription of the Constitution.
Courts and legal commentaries treat the Preamble as helpful when interpreting ambiguous provisions, but they do not use it by itself to create a new constitutional power that the text elsewhere does not support Legal Information Institute overview of the Constitution.
Quick checklist to assess whether the Preamble is being used correctly for legal claims
Use primary texts for verification
