Summary: HB 519 (Louisiana, 2026) – Courts: Provides relative to the appointment of a special master by a trial court

Purpose and core idea
- The bill adds a requirement that a special master appointed by a trial court in complex civil litigation must comply with the Code of Judicial Conduct.
- It clarifies that for complex civil actions, when a special master is appointed in accordance with existing law, the procedural rules of the Federal Rules of Civil Procedure (Fed. R. Civ. P. 53) apply to the appointment and disqualification of the master, to the extent those federal requirements are not inconsistent with Louisiana law.
- The bill retains, and explicitly links, state and supreme court rules for complex cases.

Key provisions and changes
- Enacts new R.S. 13:4165(G) to address special masters:
- For complex causes of action with multiple cases sharing common questions of fact, when consolidated by order or Supreme Court rules, any trial-court appointment of a special master must:
- Comply with the ethical requirements of the Code of Judicial Conduct (as applicable).
- Comply with the requirements of Fed. Civ. R. 53 regarding appointment and disqualification of a master, except where those federal requirements conflict with state law.
- Also be subject to the provisions of Paragraphs (2) and (6) of Subsection F of the same section (the bill references these existing provisions; the exact mechanics are governed by the existing statute).
- Relationship to existing law:
- The bill does not replace existing authority to appoint a special master; it adds a requirement that such appointments in complex cases adhere to judicial ethics and federal procedural standards (to the extent not inconsistent with Louisiana law).
- Clarifying amendments:
- House committee amendments specify that cases designated as complex under Louisiana Supreme Court rules fall under the Supreme Court’s rules and the provisions of the bill.

Who is affected
- Trial courts that appoint special masters in civil actions, particularly in complex litigation with multiple cases sharing common factual questions.
- Special masters themselves, who would be subject to the Code of Judicial Conduct in these scenarios.
- Litigants in complex civil actions where a special master is appointed (ensuring ethical standards and alignment with federal procedures when applicable).

Procedural/timeline aspects
- The bill is a state statute proposal adding new subsection G to R.S. 13:4165.
- It references existing procedural structures:
- Appointment processes under Section 4165 and Federal Rule 53 for guidance, with state law taking precedence if there is a conflict.
- Supreme Court rules for complex cases, which would govern the designation of cases as “complex.”
- The bill was introduced in the 2026 Regular Session, with amendments and floor actions noted in the legislative history (Committee amendments to tie complex designations to Supreme Court rules).

Effective date
- The bill’s text does not specify an explicit effective date beyond passage; as a Louisiana statute, it would take effect per standard constitutional provisions for new laws (typically upon enactment or a specified effective date in the final version, if provided).

Notable considerations
- Emphasizes ethical compliance (Code of Judicial Conduct) for special masters in complex cases.
- Aligns Louisiana practice with federal procedures (Fed. Civ. R. 53) for appointment/disqualification, to the extent not inconsistent with state law.
- Creates a more standardized framework for the use of special masters in complex civil litigation.

Prognosis
- If enacted, Louisiana trial courts would have clearer ethical and procedural guardrails for appointing special masters in complex actions, promoting consistency with federal practice and Supreme Court rules.
