The most sophisticated bias audit in the world is worthless under NYC Local Law 144 if the auditor is not independent within the meaning of the DCWP Final Rules. This is not a formality — in an enforcement proceeding the independence challenge is the first attack surface, and an audit that fails the independence test is treated as no audit at all. The per-violation-per-day clock has been running the whole time.
This note is a checklist. It reads the independence rule as it is written and spells out the documentation that makes a defensible answer to each element.
The rule, read carefully
6 RCNY § 5-301 defines an independent auditor as a person or group that meets three criteria:
First, the auditor is not involved in using, developing, or distributing the AEDT. "Involved in using" captures the employer's own staff auditing their own tool. "Involved in developing" captures vendor staff auditing their own product, and also captures third parties who contributed to the model's development (consultants who helped train it, for instance). "Involved in distributing" captures resellers, integrators whose revenue depends on the tool's continued adoption, and partners in the vendor's go-to-market motion.
Second, the auditor does not have an employment relationship with the employer, employment agency, or vendor. This bars in-house audits and bars audits by firms that are, for any relevant portion of their business, the employer's outsourced HR compliance function.
Third, the auditor does not have a direct financial interest, or a material indirect financial interest, in the employer, employment agency, or vendor. The direct financial interest clause is easy — no equity, no compensation tied to outcome, no revenue share. The "material indirect financial interest" clause is where most audits actually fail in practice.
What "material indirect financial interest" means in operation
The DCWP Final Rules do not exhaustively enumerate what counts as a material indirect financial interest. The reading most consistent with the rule's purpose — to ensure the audit's conclusion is not shaped by a business relationship — captures the following situations:
Ongoing consulting revenue from the audited entity. If the auditor firm has a current consulting engagement with the employer, or expects to sign one, and the consulting engagement is materially larger than the audit fee or materially important to the firm's revenue mix, the auditor has an indirect financial interest in maintaining that consulting relationship. An unfavorable audit complicates that relationship. The rule's purpose is defeated.
Cross-client dependence on the vendor. If the auditor firm audits multiple employers who all use the same vendor's AEDT, and the vendor informally refers audit work to the firm, the firm has an indirect financial interest in remaining in the vendor's good graces. This is particularly relevant where vendor-preferred auditor lists exist.
Contingent fee structures. An audit fee that depends on the audit's outcome — or on the employer's continued use of the tool post-audit — is an indirect financial interest in the favorable outcome. Fixed-fee engagements avoid this.
Shared investors or corporate affiliation. An auditor firm that shares investors with the vendor, or is owned by a parent that also owns the vendor, has a clear indirect financial interest. Less obvious: an auditor firm owned by a private equity firm that is in talks to invest in the vendor.
What does not trigger the material indirect financial interest test, in our reading, is the mere fact that an auditor has previously worked with the employer on unrelated matters (say, a tax engagement years ago), where the relationship has clearly ended and there is no expectation of renewal.
The documentation trail a defensible audit needs
Under any enforcement challenge, the auditor and the employer will be asked to produce documentation establishing independence. The following set is what a defensible audit produces at engagement and maintains throughout:
Written conflict check. Before engagement, the auditor performs a written check of relationships with the employer, the vendor, and affiliates of either. The check lists specific queries (current engagements, prior engagements in the last 24 months, shared personnel, shared investors, vendor-referred work, contingent-fee arrangements) and records the answer to each.
Independence attestation in the engagement letter. The engagement letter explicitly attests that the auditor meets the three criteria of 6 RCNY § 5-301, identifies any grey-area relationships considered and the reasoning for why they do not constitute material indirect financial interests, and establishes fixed (non-contingent) fees.
No-consulting covenant. For the duration of the audit engagement and for a defined period after (commonly 12 months), the auditor covenants not to accept consulting work from the audited entity on matters related to the audited AEDT. This is a stronger posture than the rule strictly requires but is the posture that survives challenge.
Auditor independence statement in the audit summary. The public-facing bias audit summary includes a brief statement of the auditor's independence, naming the auditor and affirming the three-criterion test was met. This is standard practice and is expected by DCWP.
Working-paper retention. The auditor retains working papers showing the independence analysis and the conflict check for the period required by DCWP guidance (and in practice a minimum of three years is prudent).
What employers should ask before accepting an auditor
Three questions answer most of the independence question, and should be answered before engagement:
Does the auditor firm currently have, or has it had in the last 24 months, any consulting, advisory, or training engagement with our company or with the vendor of this AEDT — on any matter? If yes, describe.
Does the auditor firm have any financial relationship with the vendor — as a partner, integrator, referral source, or recipient of vendor-referred work? If yes, describe.
Is the audit fee fixed, or does any portion of it depend on the audit's outcome, on our continued use of the tool post-audit, or on any other contingent condition?
An auditor who cannot answer those three questions cleanly — in writing, in the engagement letter — is an auditor whose independence will not survive enforcement challenge. The employer's choice at that point is simple: find a different auditor, or accept the risk that the audit is not an audit at all.
auditll144 operates as a structurally separate auditing practice from Lexara Advisory consulting, precisely to avoid the material indirect financial interest problem. Audit clients of auditll144 are not consulting clients of Lexara, during the audit and for a 12-month window afterward. This is documented in the engagement letter. Read the independence page.
