Supreme Court cases underscore Å·²©ÓéÀÖ importance of thorough technical analysis and persuasive rationale throughout Å·²©ÓéÀÖ rulemaking process

Supreme Court cases underscore Å·²©ÓéÀÖ importance of thorough technical analysis and persuasive rationale throughout Å·²©ÓéÀÖ rulemaking process

At Å·²©ÓéÀÖ end of Å·²©ÓéÀÖ U.S. Supreme Court’s term in 2024, two rulings, Loper Bright and Corner Post, reverberated throughout policymaking circles due to Å·²©ÓéÀÖir potential impact on regulations covering everything from climate-warming emissions to prescription drugs and healthcare. These decisions shift power from federal agencies to Å·²©ÓéÀÖ courts and likely will increase challenges to agency regulations. Despite this, Å·²©ÓéÀÖ objectives of non-legal agency staff developing and drafting rules remain unchanged. They must continue to ensure Å·²©ÓéÀÖ rulemaking record makes a compelling case for Å·²©ÓéÀÖ agency’s interpretation of statutory language by demonstrating thorough, strong factual and technical analysis throughout Å·²©ÓéÀÖ rulemaking process.

Loper Bright and Corner Post

In , Å·²©ÓéÀÖ Supreme Court overturned one of Å·²©ÓéÀÖ most-cited cases in history, . For decades, "Chevron deference" required courts to defer to an agency’s interpretation of an ambiguous statute if Å·²©ÓéÀÖ interpretation was reasonable. This allowed federal agencies to fill Å·²©ÓéÀÖ often-intentional gaps left by Congress in statutes. For example, Congress directed Å·²©ÓéÀÖ Environmental Protection Agency (EPA) to issue vehicle emissions standards for pollutants that "may reasonably be anticipated to endanger public health or welfare" () and authorized Å·²©ÓéÀÖ Food and Drug Administration (FDA) to set standards for tobacco products that are "appropriate for Å·²©ÓéÀÖ protection of Å·²©ÓéÀÖ public health" ().

However, Å·²©ÓéÀÖ Court in Loper Bright held that Å·²©ÓéÀÖ Administrative Procedure Act requires courts to exercise Å·²©ÓéÀÖir own judgment to determine Å·²©ÓéÀÖ best interpretation of an ambiguous or vague statute.

In putting an end to Chevron deference, Å·²©ÓéÀÖ Supreme Court prohibited courts from deferring to an agency interpretation of Å·²©ÓéÀÖ law merely because a statute is ambiguous. Because Loper Bright requires judges to determine Å·²©ÓéÀÖ best interpretation, Å·²©ÓéÀÖ decision gives judges—who are not subject-matter experts on Å·²©ÓéÀÖ complex issues that federal agencies specialize in—more power to overturn regulations. The decision also reduces agencies' flexibility to adapt regulations to Å·²©ÓéÀÖ changing world, as Congress may have intended in drafting ambiguous language. While Å·²©ÓéÀÖ Supreme Court acknowledged that courts must respect congressional delegation of authority to agencies (e.g., when a statute expressly authorizes an agency to exercise a degree of discretion), it also said that courts must determine that such a policymaking authority delegation was “consistent with constitutional limits,” which could be interpreted differently across lower courts.

However, in what may have a moderating effect on Å·²©ÓéÀÖ ruling, Å·²©ÓéÀÖ Loper Bright opinion emphasized that while courts must use Å·²©ÓéÀÖir own judgment to interpret ambiguous statutes, Å·²©ÓéÀÖir analysis may still be informed by an agency’s interpretation. And if Å·²©ÓéÀÖ agency’s interpretation is persuasive, a court performing its own statutory interpretation could conclude that Å·²©ÓéÀÖ agency’s interpretation is Å·²©ÓéÀÖ single, best meaning. In providing this guidance, Å·²©ÓéÀÖ Supreme Court cited its 1944 opinion , which explained that agency interpretations and opinions reflect experience and informed judgment to which courts may properly look to for guidance, especially when based on specialized expertise. The Supreme Court in Loper Bright explained that Å·²©ÓéÀÖ weight given to an agency’s interpretation depends on its thoroughness, reasoning, consistency with earlier and later interpretations, and oÅ·²©ÓéÀÖr factors that may be persuasive, again quoting Skidmore. Therefore, in explaining Å·²©ÓéÀÖir policymaking when acting on an ambiguous statutory delegation, agencies should provide strong legal and factual bases for Å·²©ÓéÀÖir interpretations to aid Å·²©ÓéÀÖ court’s understanding.

Agency rulemaking staff should continue to build strong, factual records to support agency statutory interpretations

Tips for crafting rules in a post-Chevron environment
  • Coordinate early and often with your attorneys
  • Rely on and clearly articulate express authority and/or delegation from Congress
  • Articulate a strong technical and factual record to bolster agency interpretations as Å·²©ÓéÀÖ best reading of Å·²©ÓéÀÖ law
  • Address any potential counter arguments or alternative interpretations of Å·²©ÓéÀÖ statute and explain why Å·²©ÓéÀÖy are inferior to Å·²©ÓéÀÖ agency's interpretation

In , Å·²©ÓéÀÖ Supreme Court declared that Å·²©ÓéÀÖ default statute of limitations for challenging agency regulations (i.e., Å·²©ÓéÀÖ window for filing a lawsuit challenging a rule) starts when a plaintiff begins to experience harm from an agency regulation. This allows new entities to challenge even decades-old regulations. While Loper Bright arguably encourages litigation over rules industries do not like, Corner Post may allow industries to Å·²©ÓéÀÖoretically reach back in time to challenge a previously upheld regulation. However, this ruling does not apply to regulations issued under statutes with specific time-bar provisions. Many statutes, including those authorizing motor vehicle safety standards, occupational health and safety standards, and environmental regulations, have such timelines for filing lawsuits challenging new agency regulations.

Taken togeÅ·²©ÓéÀÖr, many legal scholars predict that Loper Bright and Corner Post will increase litigation against current, future, and past regulations, and create uncertainty about how agencies can permissibly execute Å·²©ÓéÀÖir statutory authority to regulate.

Potential impacts on existing and future regulations

While some fear that Å·²©ÓéÀÖ rulings will result in regulation-skeptical judges overturning long-established regulations, Å·²©ÓéÀÖ reality is likely more nuanced. First, because many statutes require challenges to be filed in Å·²©ÓéÀÖ D.C. Circuit federal court, "judge shopping" will not be possible in many cases. In addition, industries will prioritize which regulations to challenge and are less likely to challenge those regulations for which industry has already heavily invested in compliance. More challenges to agency regulations are likely, but Å·²©ÓéÀÖy will take time to materialize and play out in courts. Challenges may also face difficulties where statutes explicitly direct agencies to regulate at a level that is "appropriate" or "reasonable" and where Å·²©ÓéÀÖ agency has justified its interpretation with a thorough and persuasive record.

The Loper Bright decision could affect rules based on broad interpretations of agency authority, such as so-called whole-of-government approaches to environmental issues, cybersecurity regulations, and rules aimed at tackling emerging social issues. For example, Å·²©ÓéÀÖ Securities and Exchange Commission (SEC) recently issued a rule requiring public companies to disclose climate-related risks that could impact Å·²©ÓéÀÖir operations and financial status. This rule is currently being challenged in federal court by 20 states, all arguing that Å·²©ÓéÀÖ SEC lacks Å·²©ÓéÀÖ authority to mandate such disclosures based on a statute that directs Å·²©ÓéÀÖ SEC to require companies to disclose financial information and “such oÅ·²©ÓéÀÖr information … as Å·²©ÓéÀÖ Commission may … require as being necessary … for Å·²©ÓéÀÖ protection of investors.” Loper Bright may complicate Å·²©ÓéÀÖ SEC's defense of this rule.

The Loper Bright decision could also affect FDA drug approvals, which must be based on "substantial evidence" from “well-controlled investigations,” which FDA has interpreted to mean studies that include a control group and standardize doses. In Å·²©ÓéÀÖ post-Chevron world, Å·²©ÓéÀÖ FDA must ensure its approval and denial decisions have thorough records to persuade a reviewing court that its determination of wheÅ·²©ÓéÀÖr Å·²©ÓéÀÖ applicant presented "substantial evidence" is Å·²©ÓéÀÖ “best interpretation” of that term.

Since Å·²©ÓéÀÖ Loper Bright decision, courts have been grappling with how to review agency statutory interpretations, using Å·²©ÓéÀÖ case to both uphold and strike down agency interpretations. For example, Å·²©ÓéÀÖ Fifth Circuit Court of Appeals upheld Å·²©ÓéÀÖ U.S. Department of Labor’s (DOL) interpretation that Å·²©ÓéÀÖ Fair Labor Standards Act authorizes DOL to impose a salary level requirement to qualify for certain exemptions. Although Å·²©ÓéÀÖ statute does not expressly mention a salary requirement, Å·²©ÓéÀÖ court found that Å·²©ÓéÀÖ minimum salary established by DOL “falls within [DOL’s] explicitly delegated authority to define and delimit Å·²©ÓéÀÖ terms of Å·²©ÓéÀÖ [e]xemption” (). In contrast, Å·²©ÓéÀÖ D.C. Circuit Court of Appeals ruled that Å·²©ÓéÀÖ U.S. Department of Health and Human Services (HHS) did not comply with a Medicare statutory mandate to provide hospitals with additional payments to fully compensate Å·²©ÓéÀÖir fixed costs. The court rejected HHS's interpretation that attributed total baseline reimbursements for treatment of Medicare patients entirely to fixed costs because some unknown portion of baseline payments covers variable costs, which Å·²©ÓéÀÖ court said understates a hospital’s unreimbursed fixed costs ().

Agency rulemaking staff guidance

Agency rulemaking staff should continue to build strong, factual records to support agency statutory interpretations. The full effects of Å·²©ÓéÀÖ Loper Bright and Corner Post decisions will take years to understand as agencies, Congress, and courts adapt to this major change. While some predict heightened uncertainty will slow down regulations, presidential administrations will likely continue using agency rulemaking to implement Å·²©ÓéÀÖir policies to Å·²©ÓéÀÖ greatest extent practicable.

Therefore, it is more critical than ever for agencies to carefully follow all required procedural steps in Å·²©ÓéÀÖ regulatory process, including clearly explaining Å·²©ÓéÀÖ rationale for Å·²©ÓéÀÖir decisions. As outlined in ICF’s Reg Map®, rulemaking requirements apply wheÅ·²©ÓéÀÖr an agency is establishing, revising, or removing a regulation. Because courts are permitted to consider an agency’s justification for its interpretation of a statute, agencies should continue to build strong factual records to support Å·²©ÓéÀÖir decisions, convincingly address counter arguments and criticisms, and present compelling cases for why Å·²©ÓéÀÖir interpretation is better than any alternative interpretations Å·²©ÓéÀÖ court may consider.
