Procedural Fairness in Australian Workplace Investigations

Why Procedural Fairness Determines Investigation Outcomes

Procedural fairness, also called natural justice, is the principle that decisions affecting a person’s rights or interests must be made through a fair process. In Australian workplace investigations, procedural fairness is not optional. It is a legal requirement that the Fair Work Commission actively tests in unfair dismissal proceedings.

The consequence of procedural fairness failures is concrete: the FWC regularly overturns dismissals where the investigation process was procedurally unfair, even when the underlying misconduct is substantiated. An employer can have strong evidence of serious misconduct and still lose an unfair dismissal claim because the investigation did not afford the respondent a fair process.

This means that procedural fairness is not just an ethical obligation. It is a practical requirement that determines whether investigation outcomes are defensible.

What Procedural Fairness Requires

The Hearing Rule

The respondent must be given a genuine opportunity to respond to the allegations before a decision is made. This requires:

• Notice of allegations: the respondent must be informed of the specific allegations, in sufficient detail that they can meaningfully respond
• Adequate time: the respondent must be given reasonable time to prepare their response (what is “reasonable” depends on complexity, but typically 5-10 business days for serious matters)
• Opportunity to respond: the respondent must be given an opportunity to respond to the allegations, either in writing, in an interview, or both
• Consideration of response: the decision-maker must genuinely consider the respondent’s response before reaching findings

The Bias Rule

The decision-maker must be impartial and free from actual or apprehended bias. This requires:

• No predetermined outcome: the investigation must be genuinely open to all possible findings, not conducted to confirm a predetermined conclusion
• No conflict of interest: the investigator and decision-maker must have no personal interest in the outcome
• Separation of roles: in serious matters, the investigator and the decision-maker should be different people

The Evidence Rule

Findings must be based on evidence and reasoned analysis, not assumption or speculation. This requires:

• Evidence collection: relevant evidence must be collected and considered
• Corroboration: findings should not rest solely on one person’s account where corroborating evidence is available
• Adverse evidence: evidence that contradicts the preferred finding must be addressed and explained, not ignored
• Balance of probabilities: workplace investigations apply the civil standard of proof (balance of probabilities), not the criminal standard (beyond reasonable doubt)

Fair Work Commission Expectations

The FWC assesses procedural fairness under section 387 of the Fair Work Act 2009, which requires consideration of whether:

• The employee was notified of the reason for dismissal
• The employee was given an opportunity to respond
• The employee was allowed a support person
• The employee was warned about unsatisfactory performance (if performance-related)
• The size of the employer’s enterprise is relevant
• Any other relevant matters

What FWC Looks For

In practice, the FWC examines:

Was the respondent told what the specific allegations were? A vague statement like “inappropriate conduct” is insufficient. The respondent must be informed of the specific conduct alleged, with enough detail to respond meaningfully.

Was the respondent given adequate time to respond? Presenting allegations and demanding an immediate response is procedurally unfair. The respondent should be given reasonable time, and in serious matters, should be advised of their right to seek legal or union advice.

Was the respondent offered a support person? Under the Fair Work Act, an employee is entitled to have a support person present during discussions about dismissal. The support person’s role is to provide emotional support, not to act as an advocate, but the right must be offered.

Did the decision-maker actually consider the respondent’s response? If the decision was made before the respondent was given an opportunity to respond, or if the respondent’s response was dismissed without genuine consideration, the process is procedurally unfair.

Was the investigation conducted by someone without bias? If the investigator or decision-maker had a personal interest in the outcome, the process may be tainted by apprehended bias.

Common Procedural Fairness Failures

Failure 1: Vague Allegations

The respondent is told they are being investigated for “misconduct” or “inappropriate behaviour” without specifics. They cannot meaningfully respond to allegations they do not understand. The FWC consistently finds this to be procedurally unfair.

Failure 2: Ambush Interviews

The respondent is called into a meeting with no prior notice, presented with allegations, and asked to respond immediately. Without time to prepare, consider the allegations, and potentially seek advice, the respondent’s opportunity to respond is illusory.

Failure 3: Predetermined Outcomes

The investigation is conducted to confirm a decision already made. Evidence supporting the preferred outcome is collected; evidence contradicting it is ignored or minimised. The investigation report reaches the conclusion that management wanted, not the conclusion the evidence supports.

Failure 4: No Support Person

The respondent is not offered the opportunity to have a support person present during investigation interviews or disciplinary discussions. This is a basic Fair Work Act requirement that is frequently overlooked.

Failure 5: Insufficient Documentation

The investigation is conducted fairly, but the documentation does not demonstrate fairness. The respondent was given an opportunity to respond, but the invitation was verbal and not recorded. The response was considered, but the decision document does not reference it. Without documentation, the FWC must rely on contested recollections.

Failure 6: Unreasonable Timelines

The investigation takes months, leaving the respondent in limbo. While there is no statutory deadline for workplace investigations, unreasonable delay can itself be a procedural fairness failure, particularly when the respondent is suspended during the investigation.

How to Document Procedural Fairness

Documentation is the evidence that procedural fairness was afforded. Without documentation, procedural fairness claims become the employer’s word against the employee’s.

Document these steps in your investigation audit trail:

1. Allegation notice: a copy of the written allegations provided to the respondent, the date provided, and the method of delivery
2. Response timeframe: the deadline given for the respondent’s response, evidence that the timeframe was reasonable
3. Support person offer: evidence that the respondent was offered a support person, their response, and any support person attendance
4. Interview records: interview notes or recordings, attendees, date, time, and location
5. Response consideration: the decision document must reference the respondent’s response and explain how it was considered
6. Conflict of interest checks: documentation that the investigator and decision-maker were assessed for conflicts
7. Evidence consideration: the decision document must reference the evidence considered, including adverse evidence

SentinelOps enforces documentation of these procedural fairness steps through configurable workflow prompts. The immutable audit trail ensures that procedural fairness documentation cannot be created or modified after the fact.

Procedural Fairness and Positive Duty

Positive Duty obligations intersect with procedural fairness requirements. Under Standard 6 (Reporting and Response), the AHRC expects organisations to investigate complaints thoroughly and fairly. This includes affording procedural fairness to respondents, even in matters involving serious allegations of sexual harassment or discrimination.

The tension between supporting complainants (Positive Duty Standard 5) and affording procedural fairness to respondents is a real challenge for investigation teams. Both obligations must be met. SentinelOps supports this by maintaining separate, access-controlled records for complainant support activities and respondent procedural fairness activities within the same case.

Frequently Asked Questions

Does procedural fairness apply to preliminary assessments?

Procedural fairness obligations are strongest when a decision that affects someone’s rights or interests is being made. During preliminary assessment, the obligation may be less extensive. However, if the preliminary assessment could itself result in adverse action (e.g., suspension), procedural fairness should be afforded.

Can we dismiss someone during an investigation?

Summary dismissal during an investigation is possible for serious misconduct, but the employer must still afford procedural fairness, including giving the employee an opportunity to respond before the dismissal decision is made. Dismissing without this opportunity is likely to result in an unfair dismissal finding.

What if the respondent refuses to participate?

If the respondent declines to participate in the investigation, document the invitation, the refusal, and any reasons given. The investigation can proceed based on available evidence. The decision document should note that the respondent was given an opportunity to respond and declined.

Is a support person the same as a legal representative?

No. Under the Fair Work Act, an employee is entitled to a support person, someone present for emotional support. The support person does not have the right to answer questions on the employee’s behalf or act as an advocate. Legal representation during workplace investigation interviews is not a statutory right, though some organisations permit it.

How does procedural fairness differ from WHS psychosocial hazard investigations?

The procedural fairness requirements are the same regardless of the investigation type. However, WHS psychosocial hazard investigations may involve additional obligations around hazard identification, risk assessment, and control measures that go beyond the individual investigation outcome.
