Critical Legal Distinction

South Carolina state courts do NOT use the Daubert standard. Many attorneys mistakenly assume SC follows federal Daubert standards. This guide explains SC's actual expert witness standard—the Jones-Council test—and when Daubert applies in federal court.

Introduction: The Critical Distinction Attorneys Must Understand

If you're an attorney preparing to introduce forensic accounting expert testimony in South Carolina, understanding the applicable legal standard is not just important—it's critical to your case. Many legal professionals mistakenly assume South Carolina follows the federal Daubert standard for expert witness admissibility. This assumption can lead to inadequate preparation and potentially unsuccessful challenges or defenses.

What You Need to Know Immediately

  • South Carolina state courts do NOT use Daubert or Frye
  • SC uses its own Jones-Council standard under Rule 702
  • Federal courts in SC (U.S. District Court) DO use Daubert
  • This distinction significantly impacts expert preparation

This comprehensive guide examines South Carolina's actual expert witness standards, explains the critical differences between state and federal practice, and provides practical guidance for attorneys working with forensic accounting experts throughout Upstate South Carolina.

South Carolina's Expert Witness Standard — The Jones-Council Test

Does South Carolina Use Daubert or Frye?

The Direct Answer: Neither.

South Carolina explicitly rejected both the Frye "general acceptance" test and the Daubert standard, choosing instead to develop its own approach through common law interpretation of SC Rule of Evidence 702.

The Foundation: State v. Jones (1979)

The genesis of South Carolina's expert witness standard comes from State v. Jones, 273 S.C. 723, 259 S.E.2d 120 (1979). The South Carolina Supreme Court established a more liberal approach than the restrictive Frye test, focusing on whether the testimony will genuinely assist the jury.

Key Principles from Jones:

  • • Expert testimony does NOT require "general acceptance" to be admitted
  • • Focus is on whether testimony assists the jury
  • • Trial judges have discretion in assessment
  • • Standard applies flexible, case-by-case approach

The Modern Framework: State v. Council (1999)

The seminal case defining South Carolina's current expert witness standard is State v. Council, 335 S.C. 1, 515 S.E.2d 508 (1999). The Court established a three-part test for expert admissibility:

The Three-Part Council Test

  1. 1. Will the evidence assist the trier of fact?

    The testimony must help the jury understand evidence beyond common knowledge.

  2. 2. Is the witness qualified as an expert?

    The witness must possess specialized knowledge, skill, experience, training, or education.

  3. 3. Is the underlying science or methodology reliable?

    The expert's methods and principles must meet a threshold of reliability.

The Jones Reliability Factors

To assess reliability under the third prong, South Carolina courts consider four factors:

1. Publications & Peer Review

Has the technique been subject to peer review and publication?

2. Prior Application

Has the method been previously applied to similar evidence?

3. Quality Control

What measures ensure reliability and accuracy?

4. Recognized Standards

Is the methodology consistent with established principles?

Critical Quote from Council: "While this Court does not adopt Daubert, we find the proper analysis for determining admissibility of scientific evidence is now under the SCRE."

South Carolina Rule of Evidence 702

The Statutory Text

"If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise."

Comparing SC Rule 702 to Federal Rule 702

South Carolina Rule 702

  • • Original text (pre-Daubert)
  • • Never amended post-Daubert
  • • Reliability via case law
  • • More flexible interpretation

Federal Rule 702 (Post-Daubert)

  • • Amended in 2000
  • • Codifies Daubert requirements
  • • Explicit reliability standards
  • • More stringent application

Jones Reliability Factors Applied to Forensic Accounting

Factor 1: Publications and Peer Review

Forensic accounting benefits from extensive professional literature and standards:

  • • AICPA forensic accounting practice guides and standards
  • • NACVA peer-reviewed standards for business valuation
  • • ACFE methodologies for fraud detection
  • • Academic journals with peer-reviewed research

Example Qualifying Questions:

"Mr. Mueller, are the methodologies you used to calculate economic damages described in professional literature?"

Factor 2: Prior Application to Similar Cases

Most forensic accounting methodologies have extensive prior application:

  • • Economic damage calculations
  • • Business valuations
  • • Fraud analyses
  • • Court acceptance nationwide

Key Point: Distinguish between established methodology and case-specific application. The former satisfies this factor; the latter goes to weight.

Factor 3: Quality Control Procedures

Quality control is particularly strong in forensic accounting:

  • • AICPA documentation requirements
  • • Verifiable calculations
  • • Internal peer review processes
  • • Discovery and opposing expert scrutiny

Factor 4: Consistency with Recognized Standards

Forensic accounting has clear, established standards:

  • • Generally Accepted Accounting Principles (GAAP)
  • • Generally Accepted Auditing Standards (GAAS)
  • • AICPA forensic accounting standards
  • • NACVA business valuation standards
  • • IRS regulations and guidance

Federal Court Practice — When Daubert Applies

Critical Distinction

State Court (SC Court of Common Pleas)

→ Jones-Council standard applies

Federal Court (U.S. District Court)

→ Daubert standard applies

The Daubert Standard

Federal courts apply the standard from Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1993), extended to all expert testimony by Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999).

The Five Daubert Factors

  1. 1. Testing: Can the theory or technique be tested?
  2. 2. Peer Review: Has it been subject to peer review and publication?
  3. 3. Error Rate: What is the known or potential rate of error?
  4. 4. Standards: Do standards exist controlling the technique?
  5. 5. General Acceptance: Has it gained acceptance in the relevant community?
