Witness Immunity for Financial Experts in Australia

What Witness Immunity Addresses

Witness immunity addresses exposure to a civil suit arising from evidence-related conduct. In Cabassi v Vila, the High Court rejected a civil action alleging a conspiracy to give false evidence. The protection supports the administration of justice, including witnesses’ freedom to give evidence without threatened suits.

Keep the other legal questions distinct. Legal professional privilege concerns protection from compulsory disclosure. Admissibility determines whether evidence can be received. Confidentiality concerns permitted use or disclosure of information. None of those questions is answered by finding that a civil suit meets an immunity defence.

An immunity also gives no assurance that the underlying calculation is correct. A court’s evaluation of an opinion and a later civil action against its author ask different questions.

Identify the Act and Its Connection to Evidence

Identify the particular act before assigning a legal conclusion to the engagement. Build a chronology that separates testimony from report preparation and any earlier advisory instruction.

For each act, record the instruction, proceeding and intended use. Then identify how the work actually connects to evidence given or prepared. An invoice headed “litigation support” cannot supply the missing connection by itself.

Distinguish these common records:

• Oral evidence identifies what the expert said and the questions they answered.
• An adopted report identifies the opinions placed before the court and their supporting calculations.
• Preparatory work shows how source records became the analysis used for evidence.
• A separate advisory instruction records a different task, such as an internal commercial decision before litigation was contemplated.

Preserve the retainer and later instructions alongside these records. The same spreadsheet can appear at different stages. Record which version was used, what changed and whether the pleaded complaint concerns an earlier calculation or the later opinion.

Match the Claim to Current Australian Authority

Match the pleaded conduct to the relevant Australian authority, including any statutory provision affecting the claim. The claimant’s label alone does not decide immunity.

Commonwealth of Australia v Griffiths [2007] NSWCA 370 addresses an expert’s testing preparatory to evidence. The Court of Appeal recognised protection beyond courtroom testimony, while requiring a connection to evidence to be given. Its reasoning distinguishes preparation from the broader investigation of facts.

In Young v Hones [2014] NSWCA 337, the court examined the work’s connection with the case in court. The engineers’ participation in an expert conclave and costs evidence formed part of the context. The decision applied Griffiths and upheld immunity on the claims before it.

Later, Qasim v Mitchell [2022] NSWSC 698 applied witness immunity to complaints about an engineer’s reports for earlier proceedings. That later application supports an Australian assessment through the evidence connection. It does not decide the position of every financial adviser.

Identify the cause of action, alleged wrong and relief sought separately. Ask which act must be proved and whether deciding the claim would revisit evidence or its preparation. Where a statute is relied on, examine its operation alongside the immunity authorities. Griffiths recognises that a clear statutory provision can displace immunity.

Apply Australian decisions to an Australian proceeding. An overseas account of expert liability does not establish that an Australian court has adopted the same rule. Equally, the solicitor’s separate role and solicitor negligence authorities cannot simply be transferred to a financial witness.

Keep Discipline and Criminal Conduct Separate

Assess a professional complaint and a civil damages claim under their respective legal routes. A successful civil immunity argument does not settle professional discipline.

In Health Care Complaints Commission v Lucire [2022] NSWCATOD 74, the tribunal rejected reliance on expert-report status as protection from disciplinary proceedings. The decision concerns medical regulation. For a financial expert, identify the applicable professional body’s powers, rules and alleged breach before drawing a disciplinary conclusion.

Griffiths expressly recognises exceptions for perjury, contempt and perverting the course of justice. Preserve any allegation of that conduct for separate legal assessment. A calculation error alone does not establish one of those offences or contempt.

Continue to work within competence, give an independent opinion and comply with the court’s directions. The Federal Court’s expert evidence practice note requires impartial assistance and explains the expert’s continuing duties. The expert witness code of conduct addresses those obligations in more detail.

An asserted immunity is therefore no reason to conceal an error, retain an opinion no longer held or disregard a direction. Deal with the evidence issue through the applicable court process while the responsible adviser assesses civil exposure separately.

Build the Financial Expert’s Assessment File

Build an act-by-claim record from the original instructions and work product. The following fictional example separates two instructions to the same forensic accountant.

Fictional Advisory Calculation and Later Report

A business first asks the accountant to calculate a recoverable debt for an internal funding decision. Proceedings are later commenced. A solicitor then asks the accountant to prepare an independent report on the debt and interest for use in those proceedings.

The first spreadsheet contains an alleged duplicated receipt. The later report uses a revised ledger and adopts a different balance. The allegation must identify which calculation caused which claimed loss.

Act	Instruction and intended use	Alleged wrong	Evidence connection to assess
Initial calculation	Estimate the debt for an internal funding decision	Duplicate receipt affects the funding decision	Preserve the original commercial purpose and any evidence that litigation was contemplated
Report preparation	Analyse the debt for identified proceedings	Wrong balance adopted in the opinion	Connect the revised ledger to the signed report and instructions
Expert evidence	Explain and adopt the report	Opinion alleged to misstate the debt	Identify the report adopted, transcript and pleaded complaint

These entries organise the assessment. They do not declare that the first act is unprotected or that the later acts are protected. The responsible adviser must apply the authorities to the actual pleaded conduct.

Keep the original ledger and its source statements. Preserve report versions, correspondence and the record explaining corrections. The working papers establish what the expert did. A financial expert witness report shows the reasoning the expert ultimately adopts.

Where statement review creates the underlying transaction record, FinTrace supplies a searchable ledger and findings cited to PDF filenames and pages. That gives the accountant direct access to the source evidence. The accountant owns the professional opinion adopted in the report.

Give the responsible adviser a separate row for each alleged act and claim, with its supporting documents and unresolved factual questions. That record allows an immunity argument to be assessed without treating the whole engagement as one protected or unprotected event.
