SCA Packaging Ltd v. Boyle (Northern Ireland)

Smart Summary

Factual and Procedural Background

The Appellee (“Appellee”) was employed by Company A (“Appellant”) and had a history of vocal-cord nodules that previously caused hoarseness. After surgery in 1992 she followed a strict voice-management regime (e.g., sipping water, limiting telephone use, avoiding shouting) which, she asserted, prevented the nodules from returning. In 2000 a workplace alteration threatened higher noise levels. The Appellee launched three consolidated claims under the Disability Discrimination Act 1995 (the “1995 Act”) alleging disability discrimination (and, in later claims, sex discrimination and unfair dismissal) between 2001 – 2002.

The Appellant disputed that the Appellee was a “disabled person” within section 1 of the 1995 Act. A tribunal in Northern Ireland therefore ordered a preliminary hearing restricted to disability status. Five days of medical evidence were heard between November 2005 and February 2006; the tribunal decided in May 2006 that the Appellee was disabled. The Appellant initiated a stated-case appeal to the Court of Appeal of Northern Ireland, which dismissed the appeal in October 2008. The present appeal to the House of Lords concerned only the meaning of the word “likely” in paragraphs 2(2) and 6(1) of Schedule 1 to the 1995 Act and, consequently, whether the Appellee met the statutory definition of disability.

Legal Issues Presented

Whether, for the purposes of paragraphs 2(2) and 6(1) of Schedule 1 to the 1995 Act, “likely” means “more probable than not” or the lower threshold “could well happen.”
Whether the tribunal’s finding that the Appellee was a disabled person during the relevant period was perverse on the evidence.
Whether the prolonged use of a preliminary-issue hearing and the stated-case procedure were appropriate and efficient in discrimination litigation.

Arguments of the Parties

Appellant's Arguments

“Likely” in Schedule 1 requires proof on the balance of probabilities; a mere risk is insufficient.
If that stricter test were applied, no tribunal could reasonably find that the Appellee’s impairment would probably have recurred during the relevant period.
The tribunal therefore erred and its decision was perverse.

Intervener’s (Equality and Human Rights Commission) Arguments

The Court of Appeal correctly held that “likely” means “could well happen,” a standard consistent with the legislation’s protective purpose.
The tribunal in fact applied the stricter “more probable than not” test and still found for the Appellee, so the decision cannot be impugned even on the Appellant’s preferred standard.
Paragraph 2(2) (recurrence) is conceptually distinct from paragraph 6(1) (effect absent treatment); both adopt the same lower threshold of likelihood.

Court's Reasoning and Analysis

1. The Lords unanimously held that in paragraphs 2(2) and 6(1) of Schedule 1 the word “likely” denotes a real possibility—something that “could well happen”—rather than an event that is “more probable than not.”

2. The statutory context is protective: Parliament intended to shield persons whose impairments pose a significant risk of substantial adverse effects if untreated. Requiring proof on the balance of probabilities would undermine that purpose.

3. Medical decision-making rarely employs a strict 51% threshold when prescribing ongoing treatment; the statutory test should mirror that clinical reality.

4. Applying the lower threshold, the tribunal’s factual findings—that cessation of the Appellee’s management regime could well cause recurrence of nodules with substantial impact—were plainly sustainable. Even if the tribunal had adopted the higher test, its conclusion still stood, so no perversity arose.

5. The Court criticised procedural delays: (a) preliminary disability hearings should be ordered only when they present a succinct knock-out point, and (b) the archaic stated-case procedure in Northern Ireland caused unnecessary duplication and delay where the tribunal had already issued a full written decision.

Holding and Implications

APPEAL DISMISSED.

Consequences: (1) A uniform United Kingdom standard now applies: “likely” in Schedule 1 of the 1995 Act means “could well happen.” Earlier authorities such as Latchman and its progeny are overruled or disapproved. (2) The Appellee remains a “disabled person” under the Act, and her substantive discrimination complaints must proceed. (3) Employers must assess risks, not probabilities, when deciding whether an employee’s treated impairment engages the Act, thereby broadening workplace obligations. (4) The decision urges reform of Northern Irish tribunal procedures to replace the stated-case mechanism with a more streamlined appellate route.
