Louisiana Civilian Law: A Defense Practitioner's Primer on Delictual Liability

Louisiana is the only US state that operates under a civilian law tradition rather than the common law. The Louisiana Civil Code, derived from the Napoleonic Code and adapted through Louisiana legislative practice, governs delictual liability in the state. For defense counsel handling Louisiana matters, the civilian framework produces both substantive and procedural distinctions from common law tort practice that require attention from the first phase of any matter.

This piece is a defense practitioner's primer on Louisiana civilian delictual liability. It addresses the civilian tradition's structural foundations, the core Civil Code provisions governing delictual liability, the operational differences between civilian and common law tort frameworks, and the practical implications for out-of-state counsel handling Louisiana matters. The piece is not exhaustive. It is a working introduction for practitioners who need to engage Louisiana delictual practice without prior civilian law training.

The Civilian Law Tradition

Louisiana's civilian law tradition derives from the legal frameworks of France and Spain, both of which exercised colonial control over Louisiana before its transfer to the United States in 1803. The Louisiana Civil Code, first enacted in 1808 and substantially revised in subsequent decades, codifies the substantive law of the state on matters including obligations, property, family, and successions. The Code is the primary source of substantive law in Louisiana, with jurisprudence (case law) serving an interpretive rather than precedential function under traditional civilian doctrine.

The practical operation of the civilian system in Louisiana is more nuanced than the doctrinal description suggests. Louisiana courts apply the Civil Code as the primary substantive authority, but jurisprudence constante (the practice of following well-established lines of judicial interpretation) produces an effective form of precedent in many areas. For defense counsel handling Louisiana matters, the working framework requires engagement with both the Code provisions and the developed jurisprudence applying them.

Delictual Liability: The Civilian Framework

Delictual liability in Louisiana is governed primarily by Civil Code articles 2315 through 2324. These articles establish the framework for what common law systems would call tort liability, but the civilian terminology and structural organization differ in ways that affect operational practice.

Article 2315: The Foundation

Civil Code article 2315 is the foundational delictual provision. It states that every act of a person that causes damage to another obliges the person through whose fault it happened to repair it. The article serves as the source of delictual liability for negligent conduct and is the starting point for any Louisiana delictual analysis. Defense counsel evaluating a Louisiana matter should begin with article 2315 and work outward through the more specific provisions that follow.

Article 2316 and Negligence-Based Delict

Article 2316 extends article 2315 to negligence, imprudence, and want of skill, establishing the negligence-based delictual framework. The article operates similarly to common law negligence in many respects, with the elements of duty, breach, causation, and damages applying in functionally equivalent terms. The civilian terminology differs (delictual liability rather than tort, fault rather than negligence) but the substantive analysis often produces results that common law counsel would recognize.

Article 2317 and Strict Liability

Article 2317 establishes a form of strict liability for damage caused by persons or things in one's custody. The provision has been the subject of significant interpretive development through Louisiana jurisprudence, with the contemporary framework requiring a showing of custody, defect or vice in the thing, and a causal connection between the defect and the damage. Defense counsel handling claims under article 2317 should engage both the Code provision and the developed jurisprudence on custody and defect.

Comparative Fault in Louisiana

Louisiana applies pure comparative fault under Civil Code article 2323. The article reduces the recovery of a person damaged by their own fault by the percentage of fault attributable to the damaged person. The framework allows recovery regardless of plaintiff fault percentage, with the percentage of fault determining the proportion of damages the plaintiff recovers. The article is the civilian equivalent of common law pure comparative fault frameworks, with the same substantive operation but the civilian doctrinal framing.

Civil Code article 2324, in its current form, abolished joint and several liability for negligence-based delictual claims. Under the 1996 revisions to article 2324, defendants in negligence cases are responsible only for their proportionate share of damages. The framework produces a pure comparative and several-only architecture that closely parallels Arizona's framework under A.R.S. §§ 12-2505 and 12-2506, with the civilian doctrinal overlay being the primary distinguishing feature.

Operational Differences from Common Law

For defense counsel trained in common law tort practice, several operational differences from common law practice warrant attention when handling Louisiana matters.

1. Code-based substantive analysis. Louisiana substantive analysis begins with the Civil Code provisions rather than common law doctrines. Defense counsel should ground analysis in the specific Code articles rather than rely on common law tort principles imported from other states.
2. Jurisprudence as interpretive rather than precedential. Louisiana courts treat jurisprudence as interpretive of the Code rather than as a source of binding precedent in the common law sense. Well-established jurisprudence constante operates similarly to common law precedent in practice, but the doctrinal framing differs.
3. Civilian terminology. Louisiana practice uses civilian terminology that differs from common law usage. Delict rather than tort. Fault rather than negligence in some contexts. Solidary obligations rather than joint and several in some contexts. Defense counsel should use the correct civilian terms in pleadings and briefs.
4. Procedural distinctions. Louisiana civil procedure operates under the Louisiana Code of Civil Procedure, which incorporates civilian doctrinal features alongside procedural mechanics that may resemble or differ from common law civil procedure. Defense counsel should engage Louisiana procedure on its own terms.
5. Prescriptive periods rather than statutes of limitations. Louisiana uses civilian terminology of prescription to describe what common law systems call statutes of limitations. The substantive framework and the operational mechanics often parallel common law SOL frameworks, but the terminology and certain doctrinal features differ.

Procedural Mechanics

Louisiana's court system operates through 42 Judicial District Courts at the trial level, five Courts of Appeal at the intermediate appellate level, and the Louisiana Supreme Court at the high court level. The substantive law applied across all levels is the Civil Code (for substantive matters) and the Code of Civil Procedure (for procedural matters). Federal courts sitting in diversity jurisdiction in Louisiana apply Louisiana substantive law under Erie principles, requiring federal practitioners to engage civilian substantive frameworks even in federal proceedings.

Practical Implications for Out-of-State Counsel

For out-of-state defense counsel handling Louisiana matters, the civilian framework produces several practical implications. Pleadings should ground claims and defenses in the specific Civil Code articles rather than common law doctrines. Motion practice should engage the Code provisions and the relevant jurisprudence directly. Discovery and expert designation should reflect the civilian substantive framework. Trial mechanics should incorporate civilian procedural features where applicable. The operational reality is that Louisiana practice requires civilian doctrinal engagement, not common law tort practice transplanted into a Louisiana caption.

Looking Forward

Louisiana's civilian law tradition will continue to govern delictual practice in the state. The Civil Code provisions covered in this primer (articles 2315 through 2324) operate as the substantive foundation, with jurisprudence developing the interpretive frameworks across the multi-tier Louisiana court system. For defense counsel with Louisiana matter exposure, ongoing engagement with Louisiana doctrinal developments is the operational requirement, supported by Louisiana co-counsel or in-house civilian law expertise where appropriate.
