A new South Carolina law shifts the balance of power when transportation companies challenge regulatory enforcement.
Most trucking and transportation owners in South Carolina don't realize that when they challenge a state agency's interpretation of a regulation—say, a DOT safety rule or a fuel tax requirement—the court traditionally starts with a built-in disadvantage. The agency gets the benefit of the doubt. That's about to change.
South Carolina's H3021, the Small Business Regulatory Freedom Act, contains a provision that fundamentally alters how courts review agency regulations and their enforcement. For transportation companies, this is material.
Sections 5 and 6 of H3021 eliminate what lawyers call "judicial deference" to agency interpretations. In plain terms: when your company goes to court to challenge how a state agency has interpreted or enforced a regulation, the court no longer has to assume the agency got it right.
Previously, courts applied a standard called Chevron deference (named after a landmark federal case). Under that framework, if an agency's interpretation of a statute or regulation was reasonable, courts deferred to it—even if the court might have read the rule differently. The agency's reading won unless it was clearly unreasonable.
H3021 changes this. Section 5 amends S.C. Code § 1-23-380(5), and Section 6 amends § 1-23-610(C), requiring courts to conduct "de novo" review. That means the court independently determines what the regulation means, without giving weight to the agency's interpretation simply because the agency issued it.
For a transportation company contesting an agency enforcement action—whether it's a compliance citation, a permit denial, or a fee assessment—this shifts leverage. You're no longer fighting uphill against an assumption that the agency knows best.
Practically, this can lower both the cost and risk of contesting regulatory overreach. If an agency interprets a rule in a way that seems unreasonable or inconsistent with the statute, you have a real chance in court without needing to prove the agency's reading was absurd. The court will decide the question fresh.
This is especially valuable for smaller transportation operations, which often lack the resources to absorb bad regulatory decisions without a fight. A level playing field in court makes it more feasible to defend your interpretation of the rules.
H3021 becomes effective upon approval by the Governor, as stated in Section 11 of the bill. Once signed, the de novo review standard applies to agency regulation challenges going forward.
If your company is currently in a dispute with a state agency over how a rule should be interpreted, consult with counsel about whether this change affects your case—timing and procedural posture matter.
This summary reflects the text of H3021, Sections 5–6, as introduced. For detailed guidance on how this applies to a specific regulatory issue, transportation business owners should consult legal counsel familiar with South Carolina administrative law.
