3.1 Precedents Cited
(a) IBRC v Comer [2014] IEHC 671
This was the controlling authority on substitution. Barr J adopted Kelly J’s formulation that a substitution application is a procedural step: the court does not finally determine the validity
of the underlying sale/assignment at that stage, but must be satisfied that there is prima facie evidence of a transmission of interest sufficient to justify substitution.
The judgment in IBRC v Comer was particularly relied upon for the proposition that disputes over redactions, full inspection of documents, and deeper validity challenges are “for another day”
(i.e., for the substantive hearing rather than the interlocutory substitution motion).
In practical effect, Comer framed substitution as a threshold inquiry: does the moving party show enough to be treated as the proper plaintiff, without foreclosing the defendant’s ability to contest
enforceability later?
(b) Tanager DAC v Doyle [2025] IEHC 275
The judgment uses Tanager DAC v Doyle to re-state a key procedural limit in mortgage repossession litigation: discovery is ordinarily not available in summary proceedings unless the matter is
adjourned to plenary hearing and pleadings have been exchanged. Barr J expressly accepted Roberts J’s approach that discovery applications are typically premature at the summary stage.
The decision also preserves a narrow safety valve: there may be “very exceptional” cases where discovery could be ordered in summary proceedings, but the Court found no exceptional feature here.
(c) ACC Loan Management Limited v Kelly [2017] IEHC 304
Cited through Tanager, this authority supports the proposition that discovery is not part of the normal toolkit of summary procedure. Barr J’s reliance on it reinforces that defendants cannot obtain discovery
merely by styling a request as necessary to mount a remittal application; rather, discovery follows the structure of pleadings and defined issues typical of plenary proceedings.
(d) Start Mortgages DAC v Larkin and Anor [2026] IEHC 377
Barr J referenced O’Higgins J’s earlier judgment for background procedural context and, more pointedly, for judicial concern about the use of sweeping allegations in motion practice. While not determinative of the legal rules,
the reference underscores the Court’s intolerance of motion-driven attempts to derail summary proceedings through collateral accusations.
3.2 Legal Reasoning
(a) The substitution test: prima facie transmission, not final adjudication
Barr J treated substitution as governed by IBRC v Comer: the Court must be satisfied there is prima facie evidence that the applicant has acquired the relevant interest such that it is
“necessary and expedient” to reflect that change in the proceedings. The Court emphasised that substitution does not cleanse defects nor resolve contested issues on assignment, notice, or enforceability; it simply places
the likely current holder of the rights in the position of plaintiff, subject to challenge at the substantive hearing.
(b) Statutory architecture: Registration of Title Act 1964 and registration as evidential cornerstone
The Court placed considerable weight on the statutory scheme governing registered charges:
-
Registration of Title Act 1964, s.62(7): once principal money is due, the registered owner of the charge may apply in a summary manner for possession.
-
Registration of Title Act 1964, s.64(1): a registered owner may transfer the charge; the transferee is to be registered as owner.
-
Registration of Title Act 1964, s.64(4): on registration, the transfer operates as a conveyance by deed and the transferee has the same enforcement rights as if the charge had been created in its favour.
-
Land Registry Rules (SI 483/2012), Rule 52: prescribed forms are to be used (relevant to the reliance on Form 56 to transfer the charge).
On the evidence, Mars was shown on the folio as registered owner of the charge (following a Form 56 transfer and registration with Tailte Éireann). That registration, in conjunction with the exhibited transfer documentation and
notification letters, comfortably satisfied the Comer threshold.
(c) Procedural containment: affidavits are evidence; particulars target pleadings
The defendant/appellant sought “particulars” directed to an affidavit used for an interlocutory application. Barr J drew a sharp doctrinal line:
pleadings define issues and attract notices for particulars; an affidavit is evidence and is not a pleading. The attempted “notice for particulars” was therefore misconceived,
and the Court characterised it as an impermissible effort to cross-examine on paper.
(d) Discovery: timing and the summary/plenary boundary
Applying Tanager DAC v Doyle, the Court held discovery is generally unavailable at the summary stage. The logic is structural:
discovery presupposes that the issues for trial have been crystallised through pleadings; summary proceedings, by design, seek a determination without the full panoply of plenary steps unless a bona fide defence
necessitates remittal.
Barr J nonetheless left the door open in the orthodox way: if remitted to plenary hearing and pleadings close, discovery may be sought in the ordinary manner by reference to relevance and necessity.
(e) Redactions: relevance, privacy, and commercial sensitivity
Consistent with the Comer approach (deferring granular disputes to a later stage where appropriate), Barr J accepted that redactions were justified to protect
(i) third-party borrower privacy and (ii) commercially sensitive deal terms. The Court’s key finding was that the redacted material was irrelevant to what had to be shown on the substitution motion:
prima facie transmission and entitlement to be plaintiff.
(f) Cross-examination: proportionality and relevance to the interlocutory issue
The Court refused liberty to cross-examine the solicitor-deponent on substitution, holding it unnecessary for the narrow procedural question. Importantly, Barr J indicated that cross-examination may be pursued
at the substantive hearing stage (or in plenary proceedings, if remitted), preserving fairness without allowing interlocutory procedure to become a proxy trial.
