Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. in Louisiana Law

How Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. applies in Louisiana: state-specific rules, key cases, and bar exam notes for Administrative Law.

State Approach

Louisiana follows the Chevron doctrine, recognizing that administrative agencies possess expertise in their regulatory domain, thus deferring to agency interpretations of ambiguous statutes unless they are unreasonable. This principle is embedded within the Louisiana Administrative Procedure Act.

State Rule
The Louisiana Administrative Procedure Act provides that courts will defer to an agency's interpretation of statutes it administers as long as the interpretation is reasonable and falls within the agency's authority.

Comparison to Federal Law

While Louisiana applies Chevron deference consistent with federal standards, it is important to note Louisiana courts often emphasize the specific statutory language and legislative intent more prominently than some federal courts. Additionally, Louisiana's civil law tradition can introduce unique interpretative elements not found in common law jurisdictions.
