Procedural fairness in UK employment termination explained, including disciplinary procedures, investigation requirements, employee rights, Acas Code of Practice, unfair dismissal claims, tribunal assessments, and compensation rules in England and Wales.

Procedural fairness in employment termination decisions refers to the requirement that an employer must follow a fair and reasonable process when dismissing an employee. In England and Wales, it is a central element of unfair dismissal law under the Employment Rights Act 1996 and is regularly examined by Employment Tribunals.
Even where an employer may have a potentially valid reason for dismissal, the decision can still be legally unfair if the process used to reach it is flawed. Procedural fairness focuses on how the decision is made, not just the outcome itself.
Legal Meaning of Procedural Fairness
Procedural fairness refers to the steps an employer must take to ensure that a dismissal is conducted in a fair and reasonable manner.
It requires that:
- The employee is treated fairly during the decision-making process
- The employer follows a structured and reasonable disciplinary procedure
- The employee is given an opportunity to respond to allegations
- The decision is based on a fair and impartial assessment of evidence
Employment Tribunals assess procedural fairness as part of the overall fairness test under section 98(4) of the Employment Rights Act 1996.
Legal Framework Governing Procedural Fairness
Procedural fairness in termination decisions is governed by:
- Employment Rights Act 1996 (particularly unfair dismissal provisions)
- Case law interpreting “reasonableness” in dismissal decisions
- The Acas Code of Practice on Disciplinary and Grievance Procedures (Acas Code of Practice)
- Contractual disciplinary procedures, where applicable
Tribunals are required to consider whether an employer acted within the “band of reasonable responses” when both the reason for dismissal and the procedure used are examined together.
Core Elements of Procedural Fairness
1. A reasonable investigation
Before making a dismissal decision, the employer must carry out a reasonable investigation into the facts.
This may include:
- Gathering documentary evidence
- Interviewing witnesses
- Reviewing relevant policies or records
- Considering mitigating circumstances
The depth of investigation should be proportionate to the seriousness of the allegations.
2. Informing the employee of the allegations
The employee must be clearly informed of:
- The allegations against them
- The evidence being considered
- The potential consequences, including dismissal
This ensures the employee can prepare a meaningful response.
3. Disciplinary hearing
A fair process normally requires a disciplinary hearing before dismissal.
At the hearing:
- The employee has the right to respond
- The employer must consider the employee's explanation
- Evidence should be reviewed objectively
- The decision-maker should not be the same person who conducted the investigation where possible
The hearing is a key safeguard in procedural fairness.
4. Right to be accompanied
Employees have a statutory right to be accompanied at disciplinary hearings by:
- A trade union representative, or
- A work colleague
This right is set out in section 10 of the Employment Relations Act 1999.
5. Reasoned decision-making
The employer must:
- Consider all evidence fairly
- Avoid bias or pre-determined outcomes
- Apply workplace policies consistently
- Ensure dismissal is proportionate to the misconduct or issue
A dismissal may be unfair if the process is rushed or predetermined.
6. Right of appeal
A fair disciplinary process includes a right of appeal.
The appeal process should:
- Be heard by someone not involved in the original decision
- Reconsider evidence objectively
- Allow the employee to challenge findings or sanctions
Failure to provide an appeal can contribute to procedural unfairness.
Procedural Fairness and Unfair Dismissal Law
Procedural fairness is a key component of unfair dismissal claims under the Employment Rights Act 1996.
Employment Tribunals assess:
- Whether the employer followed a fair procedure
- Whether any procedural defects affected the outcome
- Whether dismissal falls within the range of reasonable responses
Even if there is a valid reason for dismissal (such as misconduct or redundancy), procedural failings can render the dismissal unfair.
The Acas Code of Practice
The Acas Code of Practice on Disciplinary and Grievance Procedures sets out minimum standards for fair disciplinary handling.
Key principles include:
- Acting consistently
- Carrying out prompt investigations
- Informing employees of issues clearly
- Allowing employees to respond
- Providing a right of appeal
While the Code is not legally binding, Employment Tribunals take it into account and may adjust compensation where it is not followed.
Examples of Procedural Unfairness
Procedural unfairness may arise where:
- No investigation is carried out before dismissal
- The employee is not told of the allegations
- The employee is denied a disciplinary hearing
- The decision-maker is biased or previously involved
- The employee is not allowed to be accompanied
- No right of appeal is provided
- New evidence is introduced without opportunity to respond
Even minor procedural defects can be relevant if they affect fairness.
Procedural Fairness in Different Types of Dismissal
Misconduct dismissals
Procedural fairness is particularly important in misconduct cases, where evidence must be carefully tested.
Capability dismissals
Employers must usually show that:
- Performance issues were identified
- Support or warnings were given
- Time was allowed for improvement
Redundancy dismissals
Fair procedure requires:
- Genuine redundancy situation
- Fair selection criteria
- Consultation with affected employees
- Consideration of alternative roles
Legal Consequences of Procedural Unfairness
If procedural fairness is not met, consequences may include:
Unfair dismissal findings
An Employment Tribunal may rule the dismissal unfair even if the employer had a valid reason.
Compensation awards
Compensation may include:
- Basic award (statutory calculation)
- Compensatory award for financial loss
- Possible reductions if procedural fairness would not have changed outcome
Increased awards
Failure to follow the Acas Code of Practice may increase compensation by up to 25%.
Time Limits for Claims
Procedural fairness issues are usually raised in unfair dismissal claims, which must be brought within:
- 3 months less 1 day from the effective date of termination
Before filing a claim, employees must complete Acas Early Conciliation (Acas Early Conciliation), which pauses the limitation period.
Key Legal Principles
Employment Tribunals apply several guiding principles:
- Fairness is assessed objectively based on employer conduct
- Procedure and outcome are considered together
- Minor procedural errors may not make dismissal unfair if outcome would have been the same
- Employers are given a “range of reasonable responses” margin
Key Takeaways
Procedural fairness in employment termination decisions refers to the requirement that employers follow a fair, structured, and reasonable process when dismissing an employee. It includes proper investigation, clear communication of allegations, a disciplinary hearing, the right to be accompanied, impartial decision-making, and a right of appeal. Under UK employment law, procedural fairness is a key element of unfair dismissal claims and is assessed by Employment Tribunals under the Employment Rights Act 1996. Failure to follow fair procedures can result in a dismissal being ruled unfair and lead to compensation awards.
