The U.S. Constitution is the supreme law of the land and governs the federal government, while the Texas Constitution governs state and local government within Texas. When the two conflict, federal law controls—but Texas may provide greater protections for individual rights as long as it does not violate the U.S. Constitution.
Understanding how these two constitutions interact is essential for interpreting your rights, voting on amendments, and understanding how courts decide constitutional disputes in Texas.

What Is a Constitution?
A constitution is a foundational legal document that:
- Establishes the structure of government
- Divides power among branches
- Protects individual rights
- Serves as the highest source of law within its jurisdiction
In the United States:
- The U.S. Constitution governs federal authority nationwide
- The Texas Constitution governs state and local authority within Texas
Both apply to Texans—but in different ways and at different levels.
U.S. Constitution: Overview
The United States Constitution, ratified in 1789, is the oldest written constitution still in use.
It establishes:
- Three branches of the federal government (legislative, executive, judicial)
- A system of checks and balances
- Individual rights through the Bill of Rights (first 10 amendments)
It is intentionally brief and flexible, relying on federal statutes and court interpretation rather than constant amendment.
Texas Constitution: Overview
The current Texas Constitution was adopted in 1876 and is the seventh in Texas history.
It:
- Structures Texas state and local government
- Limits executive power through a plural executive system
- Contains extensive policy detail normally handled by statutes
It has been amended 500+ times, making it one of the longest state constitutions in the U.S. In 2025, Texas voters approved 17 new amendments.
Key Differences Between the Texas and U.S. Constitutions
1. Length and Detail
| Feature | U.S. Constitution | Texas Constitution |
|---|---|---|
| Length | ~7,500 words | 86,000+ words |
| Amendments | 27 | 500+ |
| Articles | 7 | 17 |
| Flexibility | High | Low |
Why this matters: Texas often embeds policy decisions directly into its constitution, requiring voter approval to change laws that would be statutory elsewhere.
2. Amendment Process
-
U.S. Constitution:
2/3 of Congress + ratification by 3/4 of states -
Texas Constitution:
2/3 of the Texas Legislature + majority vote of Texas voters
Result: Texas amends its constitution far more often, often via statewide ballot measures.
3. Structure of Government
Both constitutions create three branches, but Texas adds unique structural limits:
- Plural executive: Multiple independently elected statewide officials
- Elected judiciary: Most Texas judges are elected, not appointed
- Strong local governance provisions
These features intentionally restrict centralized power.
4. Individual Rights
Both constitutions contain a Bill of Rights, but Texas sometimes provides broader protections.
Examples from Texas Constitution Article I:
- Explicit victims’ rights
- Stronger religious liberty language
- Education-related provisions
Texas courts may rely on the Texas Constitution alone to protect rights beyond federal minimums.
Key Similarities Between the Two Constitutions
Separation of Powers
Both divide government into legislative, executive, and judicial branches.
Popular Sovereignty
Both derive authority from the people, as stated in their preambles.
Protection of Fundamental Rights
Speech, religion, due process, and assembly are protected under both documents.
Which Constitution Controls When They Conflict?
This is governed by the Supremacy Clause (U.S. Constitution, Article VI).
Rule:
Federal law overrides state law when the two conflict.
However:
- Texas may expand rights, but cannot restrict federally protected rights
- Texas courts may decide cases on independent state constitutional grounds
- Federal courts intervene only when federal rights are implicated
How Courts Use Each Constitution
Texas Courts
- Apply the Texas Constitution first when state rights are involved
- May resolve cases without reaching federal constitutional issues
Federal Courts
- Apply the U.S. Constitution
- Can invalidate Texas laws or constitutional amendments that violate federal rights
This dual system is a core feature of American federalism.
Real-World Example: Criminal Law & Search Rights
The differences between the two documents can significantly impact criminal laws in Texas. Texas courts sometimes interpret search-and-seizure protections more strictly under the Texas Constitution than under the Fourth Amendment.
This can affect:
- Traffic stops
- Arrests
- Evidence suppression
- Criminal prosecutions

Real-World Example: Marijuana Laws & Preemption
State vs. federal laws can impact how Texas cases are handled. For example, many states have different marijuana laws. However, regardless of local policies, marijuana possession in Texas is considered a drug crime.
- Federal law still classifies marijuana as illegal
- Texas law also prohibits recreational marijuana
- Local cite-and-release policies do not override state law
Even if Texas voters changed state law, federal law could still control under the preemption doctrine.
Why These Differences Matter
Understanding constitutional hierarchy helps you:
- Know which rights apply in a given situation
- Understand ballot propositions and amendments
- Recognize when Texas law is more protective
- Understand how courts resolve constitutional challenges
This is especially important in criminal law, civil rights, education, and voting issues.
Bottom Line
The U.S. Constitution sets the national floor for rights and the scope of government power.
The Texas Constitution governs how Texas operates—and often adds additional layers of protection and restriction.
Understanding both is essential for navigating legal rights, criminal justice issues, and civic participation in Texas.
