Why internal dismissal appeals matter

When an employee is dismissed, most UK employers provide an internal appeal process. This procedure allows the dismissal decision to be reviewed before any external legal action is taken. In many cases, an appeal is a critical step in challenging a dismissal outcome, particularly where procedural errors, incorrect facts, or unfair reasoning may have influenced the decision.

Internal appeals are also relevant in Employment Tribunal claims, as tribunals often consider whether an employee used available internal processes when assessing overall fairness.

Legal framework governing dismissal appeals

ACAS Code of Practice

The ACAS Code of Practice on Disciplinary and Grievance Procedures sets out minimum standards for fair workplace discipline processes. It states that employees should be given the right to appeal any disciplinary decision, including dismissal. Employment tribunals take compliance with the Code into account when assessing fairness.

Failure to provide or properly conduct an appeal can contribute to a finding of unfair dismissal and may increase compensation.

Employment Rights Act 1996

Under the Employment Rights Act 1996, fairness is assessed based on whether the employer acted reasonably in all circumstances. A fair appeal process is often a key part of demonstrating overall procedural fairness.

Why appealing a dismissal is important

An internal appeal can:

  • Correct factual or procedural errors
  • Challenge unfair or inconsistent decisions
  • Provide new evidence not previously considered
  • Reduce or overturn a dismissal decision
  • Strengthen a later Employment Tribunal claim if the appeal is mishandled

Tribunals often examine whether an appeal was offered and whether it was conducted fairly.

Step-by-step process for appealing a dismissal outcome

Step 1: Review the dismissal letter and appeal rights

The first step is to examine the dismissal outcome letter, which should include:

  • Reason for dismissal
  • Effective date of termination
  • Confirmation of appeal rights
  • Deadline for submitting an appeal
  • Procedure for submitting the appeal

Many employers set strict time limits, often between 5 and 10 working days.

Step 2: Check the employer's disciplinary policy

Most organisations have a disciplinary or HR policy outlining:

Appeals should follow the employer's internal procedure unless there is a clear reason not to.

Step 3: Identify grounds of appeal

A dismissal appeal should clearly set out the reasons why the decision is being challenged. Common grounds include:

1. Procedural unfairness

  • Failure to follow disciplinary procedure
  • Lack of proper investigation
  • Bias or conflict of interest in decision-making

2. Incorrect facts

  • Misinterpretation of evidence
  • Reliance on inaccurate information
  • Ignoring relevant evidence

3. Disproportionate sanction

  • Dismissal too severe for the alleged misconduct or performance issue
  • Failure to consider alternative sanctions

4. New evidence

  • Information not previously available
  • Witness evidence not considered earlier
  • Documents overlooked during investigation

Step 4: Submit the appeal in writing

Appeals should normally be submitted in writing, including:

It is important to keep a copy of the submission and proof of sending.

Step 5: Prepare for the appeal hearing

If a hearing is held, the employee may:

  • Be accompanied by a colleague or trade union representative (in many cases this is a statutory right in disciplinary hearings)
  • Present arguments against the dismissal decision
  • Refer to documents and evidence
  • Respond to management's justification

The appeal is typically conducted by a manager not previously involved in the case, although this is not always guaranteed.

Step 6: Attend the appeal hearing

During the hearing:

  • The employer explains the original decision
  • The employee presents their case
  • Questions may be asked by the appeal panel
  • Evidence is reviewed

The focus is usually on whether the original decision was reasonable based on available information at the time.

Step 7: Receive the appeal outcome

Possible outcomes include:

  • Dismissal upheld
  • Dismissal overturned and employee reinstated
  • Reduced sanction (e.g. written warning instead of dismissal)
  • New disciplinary hearing ordered

The outcome should be confirmed in writing with reasons.

Legal importance of internal appeals in tribunal claims

Impact on unfair dismissal claims

Employment Tribunals consider:

  • Whether an appeal was offered
  • Whether the appeal was conducted fairly
  • Whether errors in the original decision were corrected

A fair appeal process can reduce the likelihood of a finding of unfair dismissal.

Timing and procedural relevance

Failure to appeal is not always fatal to a claim, but it may:

  • Affect credibility
  • Limit opportunities to correct errors internally
  • Be considered when assessing overall fairness

Common issues in dismissal appeal processes

1. Lack of independence

Appeals heard by the same decision-maker or someone involved in the investigation may be considered unfair.

2. No meaningful review

An appeal that simply confirms the original decision without reconsideration may be procedurally weak.

3. Ignoring new evidence

Failure to consider relevant new information can undermine fairness.

4. Poor documentation

Inadequate records of appeal reasoning can be problematic in tribunal proceedings.

Strategic considerations when appealing a dismissal

  • Focus on clear, structured grounds rather than emotional arguments
  • Identify procedural and factual errors specifically
  • Reference employer policies and inconsistencies
  • Include evidence rather than assertions where possible
  • Maintain consistency with any later tribunal claim

Time limits for appeals

Internal policies usually impose short deadlines, commonly:

  • 5 to 10 working days from dismissal notification

Missing the deadline may result in loss of appeal rights, although employers sometimes accept late appeals in exceptional circumstances.

Relationship between appeal and Employment Tribunal claims

An internal appeal is separate from legal proceedings but can affect them by:

  • Providing additional evidence for tribunal use
  • Demonstrating attempts to resolve dispute internally
  • Clarifying employer reasoning
  • Potentially resolving the dispute without litigation

Key Takeaways

Appealing a dismissal through internal procedures is a key step in challenging termination decisions in UK employment law. The process involves reviewing dismissal reasons, identifying grounds of appeal, submitting a written challenge, attending an appeal hearing, and receiving a final outcome.

A well-prepared appeal focuses on procedural errors, factual inaccuracies, and proportionality of the sanction. Internal appeals are also significant in Employment Tribunal proceedings, where they form part of the overall assessment of fairness.
