Separation of powers divides government authority among three branches so that no single branch can dominate. In Texas government, this principle is baked into the state constitution and shapes how the legislature, governor, and courts interact with each other.
Branches of government
The U.S. Constitution creates three distinct branches: legislative, executive, and judicial. Each branch has its own responsibilities, and each operates independently of the others. This structure prevents any one group of officials from holding too much power, and it creates a system where the branches watch over each other through checks and balances.

Legislative branch responsibilities
Congress is a bicameral (two-chamber) body made up of the Senate and the House of Representatives. Its primary job is to make federal laws. Beyond lawmaking, Congress holds several other powers:
- Declaring war, levying taxes, and regulating interstate commerce
- Confirming presidential appointments (Senate)
- Ratifying treaties (Senate)
- Controlling the federal budget
Executive branch responsibilities
The President heads the executive branch and is elected to a four-year term. The executive branch is responsible for implementing and enforcing the laws Congress passes. The President also serves as commander-in-chief of the military and chief diplomat. Key executive powers include appointing federal judges and Cabinet members, negotiating treaties, and vetoing legislation.
Judicial branch responsibilities
The federal judiciary consists of the Supreme Court and lower federal courts. Its core function is to interpret the law and determine whether laws or executive actions violate the Constitution. Federal judges are appointed by the President and confirmed by the Senate, and they serve lifetime terms. Supreme Court decisions are binding on all lower courts and establish legal precedents that shape future cases.
Checks and balances
Checks and balances give each branch specific tools to limit the other two. The goal is cooperation through accountability: no branch can act unchecked, and disagreements get resolved through established constitutional processes.
Legislative checks on executive
- Congress can override a presidential veto with a two-thirds majority in both chambers
- The Senate must confirm presidential appointments and ratify treaties
- The House can impeach the President; the Senate then conducts the trial
- Congress can refuse to fund executive programs or initiatives
Legislative checks on judiciary
- The Senate confirms all federal judges nominated by the President
- Congress can impeach and remove federal judges
- Congress can propose constitutional amendments to effectively overrule Supreme Court decisions
- Congress can change the size and jurisdiction of federal courts
Executive checks on legislative
- The President can veto legislation passed by Congress
- The President can call special sessions of Congress
- The President can recommend legislation and use public influence to pressure Congress
- Executive agencies interpret and implement the laws Congress writes, which gives the executive branch significant influence over how laws actually work in practice

Executive checks on judiciary
- The President nominates federal judges, including Supreme Court justices
- The President can pardon individuals convicted of federal crimes
- The executive branch controls enforcement of court rulings
Judicial checks on legislative
- Courts can strike down laws as unconstitutional through judicial review
- Courts interpret the meaning and scope of statutes
- Courts can issue injunctions blocking enforcement of specific laws
Judicial checks on executive
- Courts can declare executive actions unconstitutional
- Courts can issue injunctions halting executive orders or policies
- Courts can compel executive officials to act or to stop certain conduct
Federalism and state powers
Federalism is the division of power between the national government and state governments. The Constitution grants specific powers to the federal government while reserving others for the states. This arrangement allows states to govern local matters while the federal government handles national concerns.
Federal vs. state authority
The Supremacy Clause (Article VI) establishes that federal law takes precedence over conflicting state law. At the same time, the Tenth Amendment reserves all powers not delegated to the federal government to the states or the people. The tension between these two principles has driven political and legal debates throughout American history and remains central to Texas politics.
Enumerated powers of the federal government
Article I, Section 8 lists the specific powers granted to Congress. These include the power to tax, borrow money, regulate interstate commerce, establish post offices, and declare war. The Necessary and Proper Clause (also called the Elastic Clause) at the end of Section 8 allows Congress to pass laws needed to carry out its enumerated powers, which has been used to expand federal authority over time.
Reserved powers of states
Under the Tenth Amendment, states retain broad authority over areas the Constitution does not assign to the federal government. Common examples include education policy, law enforcement, infrastructure, managing elections, and establishing local governments. These reserved powers are a major reason why laws on issues like criminal justice and public schooling vary so much from state to state.

Concurrent powers
Some powers belong to both levels of government. Both federal and state governments can tax, borrow money, establish courts, and make and enforce laws. When federal and state laws conflict, the Supremacy Clause means federal law wins.
Texas government structure
The Texas Constitution creates a government structure that mirrors the federal model: a bicameral legislature, an executive branch led by the governor, and an independent court system. Separation of powers and checks and balances operate at the state level just as they do nationally, though with some important Texas-specific differences.
Bicameral state legislature
The Texas Legislature has two chambers: the Texas Senate (31 members) and the Texas House of Representatives (150 members). Its primary job is making state law. Unlike Congress, the Texas Legislature meets in regular session only every odd-numbered year for just 140 days. The governor can also call special sessions to address specific issues.
Governor as chief executive
The governor is elected to a four-year term. Unlike the U.S. President, there is no formal term limit for the Texas governor in the state constitution. The governor can veto legislation, appoint state officials, grant clemency (though pardons require a recommendation from the Board of Pardons and Paroles), and call special legislative sessions. The governor also plays a significant role in the state budget process.
One thing that sets Texas apart: the governor's power is relatively weak compared to many other state governors. Several other executive officers (lieutenant governor, attorney general, comptroller, etc.) are independently elected, not appointed by the governor. This fragments executive authority by design.
State court system
Texas has a dual high court system, which is unusual. The Texas Supreme Court is the highest court for civil matters, while the Texas Court of Criminal Appeals is the highest court for criminal cases. Below them sit courts of appeals and various trial courts.
Texas judges at the appellate level are elected to six-year terms in partisan elections, meaning candidates run with party labels. This is a notable difference from the federal system, where judges are appointed and serve for life.
Separation of powers in action
Examples in Texas government
- The Texas Supreme Court has weighed in on the scope of the governor's emergency powers, including disputes over election procedures during the COVID-19 pandemic.
- The Texas Legislature has overridden gubernatorial vetoes on occasion, though this is rare because it requires a two-thirds vote in both chambers.
- Governors have called multiple special sessions to push the legislature on priority issues like property tax reform, school funding, and social policy.
Controversies and challenges
Separation of powers can produce gridlock, especially when branches disagree on policy priorities. Disputes over where one branch's authority ends and another's begins sometimes land in court, creating drawn-out legal battles. The system depends on each branch respecting the boundaries of its own power, and that respect can erode during periods of intense partisan conflict.
Importance for limited government
Separation of powers is central to the concept of limited government, which aims to prevent any single person or faction from controlling the state. By splitting authority across branches and giving each one tools to check the others, the system promotes accountability and transparency. Both the U.S. and Texas constitutions treat this principle as essential to protecting individual liberty while still allowing government to function effectively.
