Common Law and Case Precedent in Texas: How Courts Shape the Law

Texas law derives from multiple sources — enacted statutes, constitutional provisions, administrative rules, and the accumulated body of court decisions known as common law. This page examines how judge-made law operates within the Texas legal system, how appellate courts create binding precedent, and where common law authority ends and statutory or constitutional authority begins. Understanding this framework is foundational to interpreting how legal disputes are resolved across civil, criminal, and administrative contexts in Texas.

Definition and scope

Common law refers to legal principles and rules established through judicial decisions rather than through legislative enactment. In Texas, common law fills gaps where the Legislature has not spoken and operates as the default legal framework for broad areas including tort liability, contract formation, and property rights. The Texas Supreme Court has recognized this inherited body of law since statehood, drawing on English common law as it existed before 1840 — the benchmark established by the Texas legislature in the adoption statutes codified at Texas Civil Practice and Remedies Code § 5.001.

The principle of stare decisis — adherence to prior decisions — gives common law its structural coherence. When the Texas Supreme Court or the Texas Court of Criminal Appeals issues a ruling, that decision binds every lower court in the state on the same legal question. Intermediate Courts of Appeals — 14 geographic courts operating under Texas Government Code § 22.201 — issue decisions that bind trial courts within their own districts, though conflicts between courts of appeals can arise and require resolution by the higher courts.

Scope, coverage, and limitations of this page: The analysis here is confined to Texas state common law as applied in Texas state courts. Federal common law — developed through decisions of the Fifth Circuit Court of Appeals and the U.S. Supreme Court — operates under separate doctrine and is not covered here. Matters governed exclusively by federal statute, the U.S. Constitution, or federal agency regulation fall outside the scope of this page. Readers dealing with Texas state vs. federal jurisdiction questions should consult that dedicated reference.

How it works

Texas courts create and refine common law through a structured process that begins at the trial level and moves upward through the appellate hierarchy. The mechanism operates in distinct phases:

  1. Trial court application — A trial court applies existing precedent to the facts of a case. If no controlling precedent exists, the court reasons by analogy from related decisions or first principles.
  2. Appellate review — A party dissatisfied with the legal ruling may appeal. The intermediate Court of Appeals reviews questions of law de novo, meaning without deference to the trial court's legal conclusions.
  3. Supreme Court or Court of Criminal Appeals review — The Texas Supreme Court has jurisdiction over civil matters; the Texas Court of Criminal Appeals holds exclusive final jurisdiction over criminal matters (Texas Constitution, Art. V, §§ 3–5). Either court may grant review to resolve conflicts, clarify unsettled doctrine, or abrogate outdated rules.
  4. Publication and binding effect — Once published, a high-court opinion becomes mandatory authority throughout the state court system. Unpublished opinions generally lack precedential value under Texas Rule of Appellate Procedure 47.7.
  5. Legislative response — The Legislature may override a common law ruling by enacting a statute. When statute and common law conflict, the statute controls.

The distinction between mandatory and persuasive authority is critical. Mandatory authority must be followed; persuasive authority — such as sister-state decisions, law review commentary, or Restatement provisions from the American Law Institute — may inform reasoning but does not compel a result. Texas courts have, for example, cited the Restatement (Second) of Torts while simultaneously declining to adopt it wholesale.

The conceptual overview of the Texas legal system addresses how common law fits within the broader hierarchy of legal authority alongside constitutional provisions, statutes, and administrative rules.

Common scenarios

Common law principles surface most frequently in three broad contexts within Texas litigation:

Tort law — The foundational duties of care in negligence actions, the elements of fraud, defamation standards, and products liability doctrine all originate substantially in common law. The Texas Supreme Court's 1987 decision in Greenman lineage and its direct treatment of strict products liability evolved through decades of case-by-case adjudication before the Legislature codified portions of it in Texas Civil Practice and Remedies Code Chapter 82.

Contract law — Formation, consideration, breach, and remedy for contracts not governed by the Uniform Commercial Code (UCC) — which Texas has adopted in Texas Business and Commerce Code Title 1 — remain largely common law domains. Courts regularly apply common law rules on implied covenants, including the implied duty of good faith in certain employment and insurance relationships.

Property law — Easements by implication, adverse possession elements, and nuisance doctrine trace directly to common law lineage, even where Texas statutes have added procedural requirements. Readers seeking terminology grounding should consult the Texas legal system terminology and definitions reference.

A notable contrast exists between common law development and statutory codification: common law evolves incrementally through individual disputes and can be changed by a single high-court ruling, whereas statutory law requires legislative action through a formal process described at Texas legislative process and law creation. The speed differential matters — courts respond to novel fact patterns faster than the biennial Texas legislative session allows.

For practitioners and researchers, the regulatory context for the Texas legal system provides the administrative law overlay that frequently intersects with common law claims, particularly where agency action affects private rights.

Decision boundaries

Common law authority in Texas operates within defined limits. Four boundaries constrain its reach:

Constitutional supremacy — Both the Texas Constitution and the U.S. Constitution override any common law rule. Courts cannot create or sustain common law doctrine that violates constitutional guarantees. The Texas Constitution, Article I (the Bill of Rights), and the Texas due process protections framework take precedence over judge-made rules.

Statutory preemption — When the Texas Legislature enacts a comprehensive statutory scheme, courts generally hold that common law claims in that domain are preempted or displaced. The Texas Workers' Compensation Act, codified in Texas Labor Code Title 5, is a standard example: it substitutes a statutory remedy for common law tort claims against covered employers, extinguishing the worker's common law negligence suit in exchange for no-fault benefits.

Sovereign immunity — The state and its subdivisions retain immunity from suit unless the Legislature has expressly waived it. Common law cannot independently override governmental immunity. The Texas Tort Claims Act (Texas Civil Practice and Remedies Code Chapter 101) marks the outer boundary of permissible claims against governmental entities. The Texas sovereign immunity and governmental liability reference addresses this boundary in detail.

Jurisdictional limits — Common law developed in state courts does not bind federal courts sitting in diversity. Federal courts apply Texas common law as interpreted by the Texas Supreme Court, but the Erie doctrine (established in Erie Railroad Co. v. Tompkins, 304 U.S. 64 (1938)) directs federal courts to follow state high court precedent, not create independent federal common law on state-law questions.

A comparison across case types is illustrative. In civil litigation, the Texas Supreme Court controls final common law development; a losing party cannot appeal a Texas Supreme Court ruling on a state common law question to the U.S. Supreme Court unless a federal constitutional issue is present. In criminal matters, the Texas Court of Criminal Appeals holds equivalent finality — its interpretations of state criminal common law principles, such as the common law elements surviving into the Texas Penal Code, are unreviewable by federal courts absent constitutional error.

The central reference for navigating the structure of courts that generate and apply these rules is the Texas court system structure page, which maps each court's jurisdictional reach and precedential role. Readers examining how statutes interact with judge-made rules across the full system will find the home reference index a useful orientation point.
