Anonymised Judicial Summary

Factual and Procedural Background

This summary synthesises the two linked appeals heard together under anonymous case labels "Wicked Vision" and "Barton Turns". Both appeals concern applications to amend existing whistleblowing-related unfair dismissal claims so as to add detriment claims based on section 47B of the Employment Rights Act 1996 ("the 1996 Act"), following the 2013 amendments to that section.

Wicked Vision (summary)

In Wicked Vision the claimant (the employee) was employed by Company A as Head of UK Sales from December 2019 until February 2021, when he was dismissed on grounds recorded as redundancy. The claimant alleged that the true reason for dismissal was that he had made protected disclosures and therefore brought a claim of unfair dismissal under section 103A (Part X). Shortly before a case management hearing the claimant sought permission to amend the pleaded case to add complaints that he had been subjected to various detriments contrary to section 47B (Part V), including an allegation that he had been subjected to the detriment of dismissal by an individual closely connected with the employer. The Employment Tribunal (ET) granted permission to amend, leaving any issue of lateness for later determination. On appeal to the Employment Appeal Tribunal (EAT), the employer argued that the amendment was barred by section 47B(2) unless the individual alleged to have caused the dismissal had been joined; the EAT allowed the employer's appeal. The present court considered the appeals and the binding status of a prior Court of Appeal decision (referred to below) before giving its judgment.

Barton Turns (summary)

In Barton Turns the claimant (an employee) brought a complaint of automatically unfair dismissal under section 103A based on protected disclosures (and also under section 100(1)(c)). The claimant applied to amend the claim to add complaints of non‑dismissal detriments under section 47B, some of which were said to include the dismissal. The ET allowed amendments in respect of non‑dismissal detriments (describing the change as a relabelling) but refused to allow the amendment that would add the dismissal itself as a detriment. On appeal to the EAT the claimant relied on the same prior Court of Appeal authority as in Wicked Vision; the EAT held that it was bound by that authority and allowed the claimant's position as to the dismissal‑as‑detriment point. The employer appealed to the Court of Appeal on several grounds including a discrete ground (Ground 3) about some further factual amendments which the ET and EAT had treated as relabelling; that discrete point was also considered.

Legal Issues Presented

1. Whether an Employment Tribunal erred in law in refusing (or in granting) permission to amend an unfair dismissal claim under section 103A (Part X) so as to add a detriment claim under section 47B (Part V) that is based on the detriment of dismissal by a co‑worker or individual associated with the employer.
2. Whether the Employment Tribunal (and this court) are bound by the Court of Appeal decision in the earlier authority addressing the meaning and reach of section 47B(2) and, if so, the consequences for amendment applications of the type at issue in these appeals.
3. In Barton Turns, whether amendments that add an express allegation that previously pleaded events "amounted to a detriment" were permissible as relabelling or instead introduced a new, time‑barred cause of action (Ground 3 of the employer's appeal in that case).

Arguments of the Parties

Claimants / Employees

• The employees submitted that permission to amend to add section 47B detriment claims should have been granted. They argued the tribunals were bound by the prior Court of Appeal decision interpreting section 47B (referred to in the text) and that the facts in these appeals did not distinguish those authorities.
• In both appeals the employees relied on the proposition that the 2013 amendments to section 47B created a right to bring detriment claims against co‑workers and agents (with vicarious liability for the employer), and that such claims could co‑exist with a Part X unfair dismissal claim.
• In Barton Turns the claimant argued the factual amendments at issue were properly described as relabelling and did not introduce a new cause of action out of time.

Employers

• The employers urged that section 47B(2) barred the bringing of a detriment claim that "amounts to dismissal" where the worker is an employee — such detriments should be pursued under Part X only. In particular, they argued that a claim based on dismissal as a detriment could not be advanced against the employer by relying on vicarious liability grounded in section 47B(1B) unless the co‑worker alleged to have committed the act had been joined as a respondent.
• The employers contended that the earlier Court of Appeal decision relied on by the employees did not bind the tribunals on the point at issue or did not go so far as to permit the amendments sought in these appeals; they also challenged whether that authority should bind this court.

Intervener

A whistleblowing charity intervened by written and oral submissions in support of the employees' position. The intervention was permitted and addressed the public interest and statutory protection context for whistleblowers. (No further detailed arguments from the intervener are set out in the provided opinion.)

Court's Reasoning and Analysis

Structure of the analysis:

1. The court examined the statutory text of section 47B(2) of the Employment Rights Act 1996 as amended and the overall architecture of Parts V and X of the Act.
2. It reviewed prior authorities which interpret the relationship between detriment claims (Part V) and unfair dismissal (Part X), notably the pre‑2013 analysis in the authority summarised above (Precedent B) and the post‑2013 Court of Appeal decision central to these appeals (Precedent A).
3. The court then set out its own construction of section 47B(2), explained why it considered that construction to follow plainly from the statutory language and legislative scheme, and explained why that construction differs from the interpretation in Precedent A.
4. Finally, the court addressed whether it was bound by Precedent A notwithstanding its disagreement, applying the doctrine of precedent and evaluating the ratio and consequences of that prior decision for the present appeals.

Key points of the court's textual and statutory analysis (based on the provided opinion):

• Plain meaning: Section 47B(2) states that the whole of section 47B "does not apply where (a) the worker is an employee, and (b) the detriment in question amounts to dismissal (within the meaning of Part X)". The court emphasised that this is an unambiguous exclusion of Part V remedies in cases where the substance of the complaint is a dismissal by the employer within Part X.
• Three‑element inquiry: The court explained that determining whether the exclusion applies requires asking (i) whether the detriment complained of is, in substance, a dismissal; (ii) whether the compensation sought arises from losses consequential on the dismissal (i.e. within Part X) or instead relates to pre‑dismissal loss; and (iii) whether the employer dismissed the employee (the court noted that a dismissal is, by definition, an act of the employer, even if implemented through an individual co‑worker or agent).
• Legislative design and consistency: The court observed that the draftsman had chosen, in other parts of Part V, to disapply whole sections or particular subsections when Part X applied. When section 47B was amended in 2013 to add individual and vicarious liability provisions, the court noted that the subsection 47B(2) was not altered to carve out those new subsections — a deliberate drafting position that supports a textual reading that the whole of section 47B remains disapplied where the detriment "amounts to dismissal".
• Responses to the arguments in Precedent A: The court set out why it considered the earlier Court of Appeal decision (Precedent A) had adopted a purposive construction that departed from the clear wording of section 47B(2). The court explained three principal objections to the reasoning in Precedent A as to statutory interpretation: (a) it treated the statutory language as ambiguous or in need of remedial gloss when the court considered it was clear; (b) it relied on an expectation that Parliament would have intended "identical remedies" across Parts V and X even though the statutory scheme expressly provides different remedies; and (c) it treated dismissal by a co‑worker as conceptually distinct from dismissal by the employer when, for the purpose of Part X, dismissal is an employer act and section 47B(1B) already treats co‑worker acts as done by the employer for vicarious liability purposes.
• Doctrine of precedent: Despite its disagreement with Precedent A, the court concluded that the present tribunals and the Court of Appeal were bound by the ratio in Precedent A. The court analysed the ratio and scope of that earlier decision and determined that it must be followed in these cases. As a result, even though the court provided its own construction and stated why it would have reached a different outcome if free to depart, it applied the binding precedent.

Application to the two appeals:

• Because Precedent A was binding and had been applied by the EAT in the related case, an ET considering an application to amend an unfair dismissal claim under section 103A so as to add a section 47B(1A)/(1B) detriment claim (based on dismissal by a co‑worker) would, subject to ordinary discretionary considerations (including time limits and prejudice), be bound to allow such an amendment.
• The court therefore concluded that the ET decisions in the two appeals had to be resolved by reference to Precedent A: in Wicked Vision the earlier refusal was wrong and the employee's appeal had to be allowed; in Barton Turns the employer's appeal against the ET's allowance of the relevant amendment had to be dismissed (the EAT had already declined to follow the divergent EAT decision in Wicked Vision and had applied Precedent A).
• On the discrete procedural point in Barton Turns (Ground 3), the court accepted the ET and EAT approach that the specific late amendments were relabelling of matters already pleaded and thus properly allowed under established principles governing amendments (weighing prejudice and the connection to originally pleaded facts).

Holding and Implications

Holding:

• Wicked Vision — APPEAL ALLOWED: The court held that, because it is bound by the earlier Court of Appeal authority (Precedent A), the ET should have permitted the proposed amendment to add a section 47B detriment claim grounded on dismissal by a co‑worker (with vicarious liability against the employer), subject to any discretionary bars such as time limits.
• Barton Turns — APPEAL DISMISSED: The employer's appeal against the ET's permission to amend (to add detriment allegations, including those asserting detriment in the form of dismissal) was dismissed. On the discrete contention (Ground 3) that some pleaded amendments were out of time or introduced a new cause of action, the court held the ET and EAT were correct to treat those particular amendments as relabelling arising from the same pleaded facts and therefore properly allowed.

Implications:

• Because this court considered itself bound by the earlier Court of Appeal decision (Precedent A), Employment Tribunals and the Employment Appeal Tribunal must follow that interpretation when faced with similar amendment applications: an employee who has pursued a Part X unfair dismissal claim may, subject to ordinary procedural defences (including limitation and prejudice), be permitted to amend to add a section 47B(1A)/(1B) detriment claim based on dismissal by a co‑worker without necessity to join that co‑worker as a respondent.
• The court recorded its disagreement with the construction in Precedent A and explained why, on textual and structural grounds, it would have reached a different view if free to do so; however, because of the doctrine of precedent, it applied the binding authority. The court noted that the present state of conflicting decisions at different levels can only properly be resolved by the Supreme Court or by legislative amendment.
• No new precedent altering the statutory meaning of section 47B(2) was established by this judgment: the court applied existing precedent (Precedent A) even while providing a detailed, dissenting textual analysis for future consideration by a higher appellate court or by Parliament.

Practical note for tribunals and practitioners (as derived from the judgment): Where an employee who has brought a Part X automatic unfair dismissal claim seeks to amend to add a Part V section 47B detriment claim based on acts of a co‑worker that are said to amount to dismissal, tribunals must consider (i) whether they are bound by the earlier Court of Appeal authority on point; (ii) whether the amendment is otherwise barred on discretionary grounds (delay, prejudice, time limits); and (iii) whether any pleaded detriment in substance amounts to dismissal (in which case the textual construction in the court's preferred analysis would treat section 47B as disapplied, although that preferred analysis was not followed because of binding precedent).
