Consistency in Disciplinary Proceedings

Consistency in disciplinary treatment is a key factor in fair dismissal. Treating similar cases differently raises fairness concerns.

Why Consistency Matters

Fairness Principle

Employees expect:

• Similar cases treated similarly
• No favouritism
• Predictable outcomes
• Equal standards applied

Legal Significance

Tribunals consider:

• How comparable cases were handled
• Whether treatment was consistent
• If differences were justified

Inconsistency can make dismissal unfair.

What Consistency Means

In Practice

Aspect	What's Expected
Investigation	Similar thoroughness
Process	Same procedures followed
Standards	Same behaviour standards
Sanctions	Comparable outcomes

Not Identical Treatment

Consistency doesn't mean:

• Exactly the same outcome every time
• Ignoring individual circumstances
• Mechanical application of rules

It means similar cases shouldn't produce wildly different outcomes without good reason.

Using Comparators

Finding Comparators

Look for cases where:

• Similar misconduct occurred
• Same or similar role
• Same or similar circumstances
• Different outcome

Good Comparators

Factor	Should Be Similar
Type of misconduct	Same category
Severity	Comparable seriousness
Timing	Reasonably recent
Role level	Similar position

Weak Comparators

Less persuasive if:

• Different type of misconduct
• Very different circumstances
• Long ago
• Different part of organisation
• Different decision-maker (sometimes)

When Differences Are Justified

Legitimate Reasons

Factor	Why It Matters
Severity	More serious = harsher sanction
Previous record	Clean record may mitigate
Length of service	Long service may mitigate
Attitude/remorse	Shows understanding
Position	Seniority brings higher standards
Circumstances	Context matters

Example

Two employees caught sleeping:

• Employee A: First offence, 10 years' service, admitted it, apologised - Final warning
• Employee B: Previous warning, 2 years' service, denied it despite evidence - Dismissal

Difference may be justified by different circumstances.

Challenging Inconsistency

At Disciplinary Hearing

Raise concerns:

"I'm aware that [Name] was given a warning for the same misconduct. Why am I being treated differently?"

At Appeal

Grounds for appeal:

• Inconsistent with similar cases
• Others not dismissed for same
• No justification for difference

At Tribunal

Argue:

• Comparable employee treated more leniently
• No reasonable explanation for difference
• Shows dismissal outside reasonable range

Evidence of Inconsistency

What You Need

• Details of comparator case
• What the misconduct was
• What sanction was given
• Why cases are similar
• Source of information

Getting Information

You can:

• Ask about previous similar cases (at hearing)
• Request through subject access (GDPR)
• Use knowledge from colleagues (carefully)
• Request disclosure (at tribunal)

Limitations

You may not be entitled to:

• Confidential details of others' cases
• Complete disciplinary files
• Names in all circumstances

Employer's Position

Defending Consistency

Employer should document:

• Why cases are different
• What factors distinguished them
• Why different outcome was justified

Common Defences

Defence	Argument
Different circumstances	Not truly comparable
Previous record	Employee had warnings
Position/role	Higher expectations
Attitude	Different response to allegations
Evidence	Stronger evidence in this case

Tribunal Approach

What Tribunal Examines

• Were cases genuinely similar?
• Did employer treat them differently?
• Was there justification?
• Was decision within reasonable range?

Band of Reasonable Responses

Tribunals allow for:

• Some variation in outcomes
• Employer discretion
• Consideration of circumstances

But not:

• Arbitrary differences
• Obvious inconsistency
• Unjustified disparity

Practical Tips

For Employees

1. Identify comparators - similar cases you know of
2. Document similarities - why cases are comparable
3. Raise at hearing - put employer on notice
4. Use at appeal - grounds for appeal
5. Preserve evidence - for potential tribunal

Questions to Ask

• How have similar cases been handled?
• Why is my case being treated differently?
• What justifies a different outcome?
• Can you provide examples of comparable cases?

For Employers

1. Keep records - of how cases were handled
2. Document reasoning - for each decision
3. Consider precedent - before deciding
4. Justify differences - explain why outcomes vary
5. Train managers - on consistent approach

Managing Consistency

Policy Role

Policies should:

• Set clear standards
• Guide decision-making
• Promote consistency
• Allow for individual circumstances

Record Keeping

Keep records of:

• All disciplinary cases
• Outcomes and reasoning
• Selection criteria used
• Factors considered

Training

Ensure managers:

• Understand expectations
• Know the policy
• Apply consistent standards
• Document their reasoning

Limitations of Consistency Arguments

When It Won't Help

Consistency argument may fail if:

• You can't identify comparator
• Cases are genuinely different
• Your case is more serious
• Previous cases wrongly decided
• Long time between cases

Previous Leniency Not a Defence

If employer was too lenient before:

• Doesn't mean they must always be
• Can correct and apply properly
• But should warn of change

Balance

Consistency vs Individual Assessment

Good practice:

• Similar cases, similar outcomes
• But consider individual circumstances
• Document reasoning
• Explain any differences

Avoiding Problems

Employers should:

• Apply standards consistently
• Document decisions
• Explain departures
• Review for patterns
• Train decision-makers
