Supreme Court (Ireland) – Anonymized Summary

Citation: [2026] IESC 10

Judge: Judge Collins (judgment delivered 18 February 2026)

Factual and Procedural Background

The proceedings concerned the ownership of six valuable stained-glass works commissioned in 1927 from an artist’s studio and installed in a long-established café premises in The City in March/April 1928. The works comprised four “Four Orders” windows set into openings on one wall, and two “Swan Yard” windows associated with openings on another wall. The works were designed to function as windows and were originally fitted with mechanisms intended to facilitate opening and ventilation; over time, various alterations occurred, including removal for safekeeping/refurbishment, changes to mechanisms, relocation of the “Swan Yard” works to an internal wall in 1987, and later backlighting.

Company A (the landlord’s successor in title) claimed ownership on the basis that, upon installation, the works became “part and parcel” of the premises (i.e., part of the structure) and therefore belonged to the freehold. Company B (the tenant) had occupied the premises continuously since 1927 (with changes in the tenant’s ownership in 1987). In December 2020, Company B purported to transfer ownership of the works to Company C (its parent company), with a licence back to Company B for continued use; Company A challenged the transfer’s validity, resulting in the litigation. Company C’s claim depended entirely on Company B having owned the works at the time of the 2020 transfer.

In the High Court, Judge McDonald (after a six-day trial) held that Company A owned the “Four Orders” works but that Company B owned the “Swan Yard” works as tenant’s fixtures removable under section 17 of the Landlord and Tenant (Amendment) Act 1860 (Deasy’s Act) ([2023] IEHC 25).

Both sides appealed. The Court of Appeal (majority) allowed Company A’s appeal and dismissed Company B’s cross-appeal, holding Company A owned all six works ([2024] IECA 199). Judge Whelan dissented.

The Supreme Court granted leave to appeal on significant and complex fixtures issues ([2025] IESCDET 15), but the appeal ultimately focused on factual/evidential limits of judicial fact-finding, particularly (i) who paid for the works and (ii) whether the “Swan Yard” works were installed in 1928 as true exterior windows or as an inner decorative layer in a “double fenestration” arrangement.

Legal Issues Presented

1. Whether the six stained-glass works, upon installation in 1928, became “part and parcel” of the premises (i.e., structural parts of the realty) such that they belonged to Company A and could not be removed by Company B.
2. If the works were not “part and parcel” of the premises, whether Company B established the necessary preconditions to treat them as tenant’s fixtures removable under section 17 of Deasy’s Act, including proof that they were affixed by the tenant at the tenant’s sole expense.
3. Whether the evidence was adequate to permit reliable findings on the disputed factual questions, and how the burden of proof should operate where the evidence was fragmentary and ambiguous.

Arguments of the Parties

Defendant’s (Tenant’s) Arguments

• The “fundamental issue” was whether the works were “part and parcel” of the premises or tenant’s fixtures; it contended they were not structural parts of the premises.
• The works were not part of the original structure when the tenant went into occupation; they were readily removable; and they were essentially ornamental, installed to enhance the café trade.
• The “Swan Yard” works were said to have been installed as part of a “double fenestration” arrangement (inside plain-glass windows) such that they were not true exterior windows, but decorative panels (“mock windows”).
• On payment, the tenant relied primarily on a March 1928 board minute (“the Board Minute”) as establishing that expenditure on café fittings/fixtures was the tenant’s liability; it argued this was sufficient to meet the “threshold issue” that the tenant paid for (or should be treated as having paid for) the works.
• It argued it could succeed even if it did not overturn the Court of Appeal’s finding on the 1928 installation method, provided payment was established.

Plaintiff’s (Landlord’s) Arguments

• All six works were commissioned and designed as windows for the premises and, on installation, became “part and parcel” of the premises (structural), and thus belonged to the landlord’s title.
• The “double fenestration” theory lacked reliable evidential support and was inconsistent with the design and ventilation purpose of the works and with expert evidence.
• Even if the works were not structural, the tenant could not claim a right of removal without proving they were tenant’s fixtures, including proof of payment by the tenant (a “threshold” requirement under section 17 of Deasy’s Act), which the tenant had not established.

Court's Reasoning and Analysis

(1) Governing framework. The Court treated the dispute through the accepted threefold classification of objects as chattels, fixtures, or “part and parcel” of land. It was common case that if the works became “part and parcel” of the premises on installation in 1928 (i.e., structural in the legal sense), they could not be tenant fixtures and could not be removed by the tenant in any circumstances. By contrast, section 17 of Deasy’s Act applies only to tenant fixtures and requires, as a fundamental precondition, that the item was erected and affixed by the tenant “at his sole expense.”

(2) Identification of the key disputed facts. The Court identified two disputed factual issues: (i) who paid for the works, and (ii) how the “Swan Yard” works were installed in 1928 (true windows versus “double fenestration”). It emphasised the severe evidential gaps and the importance of burden of proof where evidence is fragmentary or inadequate.

(3) The “Four Orders” works. The Court accepted the High Court’s finding (also upheld by the Court of Appeal) that these works were installed and functioned as windows from 1928 and were not part of any double-fenestration arrangement. A later video (1998) and physical evidence were treated as strongly supporting this finding. The Court rejected the tenant’s attempt to rely on a witness statement regarding lack of weathering as displacing those findings, and noted the admitted statement did not support the tenant’s double-fenestration theory.

(4) Threshold issue: payment for the works. The tenant accepted it bore the burden of proving it paid for, or undertook liability for, the works. The tenant relied primarily on the March 1928 Board Minute. The Court held the minute was insufficient to discharge that burden: it did not mention the stained-glass works; its listed items were classic café fittings (ovens, tables, chairs, counters) and reliance on a general phrase (“other café fittings and fixtures”) to include the stained-glass works was speculative; the minute was fragmentary amid an evidential void; and parsing it as determinative would give it an unwarranted evidential status. The Court also rejected the inference that a cash payment of £200 in June 1928 was probative of payment by/on behalf of the tenant. Applying the approach endorsed in The Popi M and Quinn, the Court held that where evidence is inadequate to permit a reliable positive finding, deciding against the party with the burden is the only just course. The tenant therefore failed the threshold condition for any tenant-fixture claim, which was fatal to its ownership claim.

(5) The “Swan Yard” installation method (“double fenestration”). Although payment failure was dispositive, the Court addressed this issue and agreed with the Court of Appeal majority. It held the High Court’s “double fenestration” conclusion was unsupported by adequate evidence and was inconsistent with multiple factors: the works were designed to function as windows with ventilation mechanisms; effective ventilation was critical; a dual-window arrangement would severely compromise ventilation; unchallenged expert evidence indicated no known usage of dual systems by the artist or peers of the era; and the artist’s surviving correspondence referred to “windows” and gave no hint of a novel dual system. The Court considered that observations in 1987 did not reliably establish the 1928 configuration given intervening alterations (including a bricked-up opening and later backlighting), and that extrapolation backward was unjustified. It concluded the reasonable inference was that the “Swan Yard” works were installed in 1928 as windows for the purpose for which they were commissioned and designed.

(6) Classification as “part and parcel.” The Court held that both the “Four Orders” and “Swan Yard” works became “part and parcel” of the premises on installation in 1928, were not fixtures (and still less tenant fixtures), and thus belonged to the landlord’s title irrespective of any payment question. It rejected the contention that removability, installation after the café opened, or ornamental character prevented the works from being structural in the relevant legal sense, and distinguished the “ornament cases” because these works were not purely decorative and were site-specific commissions for the premises.

Holding and Implications

HOLDING: APPEAL DISMISSED. The Supreme Court affirmed the order of the Court of Appeal. It held that all six stained-glass works became “part and parcel” of the premises upon installation in 1928 and are the property of Company A (the landlord’s successor in title). The Court further held that, in any event, Company B failed to prove the threshold requirement that it paid for (or undertook liability for) the works, preventing any claim that they were tenant fixtures removable under section 17 of Deasy’s Act.

Implications: The immediate effect was to defeat Company B’s and Company C’s asserted ownership and to uphold Company A’s claim to the works. The judgment emphasised that, where the evidence is fragmentary and ambiguous, courts may be compelled to resolve a disputed factual issue by applying the burden of proof rather than by speculative inference. The decision applied existing fixtures principles to the particular evidential record; it did not purport to create new legal tests.
