Danske Bank A/S v Coyne

Factual and Procedural Background

The case concerns the enforceability of a guarantee dated 9th April 2008, entered into as security for substantial borrowings by a company ("the Principal Debtor"). The Defendant provided the guarantee in favor of National Irish Bank Limited, an entity which had ceased to exist under that name at the time of the guarantee. The Defendant contended that the guarantee was unreliable due to disputed timing and circumstances of signing, the incorrect bank name used, and the scope of the guarantee's terms.

An earlier loan with limited security was replaced by a €4 million loan in December 2006, secured in part by a guarantee from the Defendant signed in January 2007. The disputed guarantee of April 2008 was drafted by a bank manager from an old template containing the outdated bank name. The Plaintiff, Danske Bank A/S, is the lawful successor to National Irish Bank's rights and liabilities.

On 2nd April 2008, the Principal Debtor was loaned €8.15 million secured by a floating charge, a letter of guarantee from the Defendant for €8 million, and legal mortgages over certain development sites. The guarantee was a condition of this loan facility.

The Defendant’s signing of the guarantee was contested: the bank manager stated it was signed on 9th April 2008 in his office, while the Defendant claimed it was signed later, on 21st July 2008. The Defendant’s evidence did not establish that he intended to contract with an entity other than National Irish Bank or that he was unaware of the guarantee’s purpose.

A letter from the bank dated 27th October 2009 acknowledged the error in the bank name on the guarantee and explained the correct intention was for the guarantee to benefit the bank under its trading name "National Irish Bank". A formal demand for repayment under the guarantee was made on 24th November 2009.

The Plaintiff’s statement of claim asserted the guarantee was intended to secure the loan and that the bank name error was a mistake not affecting the parties' common intention. The Defendant denied this and argued the guarantee was unenforceable as written.

Legal Issues Presented

1. Whether the guarantee dated 9th April 2008 is enforceable despite the misnomer of the bank's name.
2. Whether the Defendant intended to contract with the predecessor entity of the Plaintiff despite the name discrepancy.
3. Whether the guarantee’s terms operate to secure the liabilities of the principal debtor as intended.
4. Whether rectification of the guarantee document is necessary or whether the contract can be construed to correct the mistake by construction.

Arguments of the Parties

Plaintiff's Arguments

• The guarantee was intended to secure the loan facility extended to the Principal Debtor.
• The naming of "National Irish Bank Limited" was a clerical error and did not reflect the parties' common intention.
• The Plaintiff is the lawful successor to National Irish Bank and thus entitled to enforce the guarantee.
• The guarantee should be enforced as written or rectified to reflect the true intention.

Defendant's Arguments

• The guarantee was signed under disputed circumstances, including the timing and presence of witnesses.
• The guarantee named a non-existent entity, National Irish Bank Limited, thus making it unenforceable.
• The Defendant did not intend to contract with the Plaintiff or its predecessor under the terms stated.
• The mortgages secured the loan, and in the absence of a proper guarantee, the Defendant's liability should be limited.

Court's Reasoning and Analysis

The Court examined the guarantee’s enforceability by applying established principles of contract construction and rectification. It acknowledged the guarantee was drafted using an outdated template containing a misnomer of the bank’s name, which was no longer in use at the time of signing. The Court found the Plaintiff to be the lawful successor of National Irish Bank and thus entitled to enforce the guarantee.

The Court relied on the principle that contracts are to be construed in light of the factual matrix known to the parties, not merely by the literal text. It applied the doctrine of "correction of mistakes by construction," whereby an obvious and clear mistake in a contract can be treated as corrected if the parties’ common intention is evident.

The Defendant’s evidence did not establish any contrary legal intention to contract with an entity other than the Plaintiff’s predecessor. The Court found the misnomer to be a shared mistake that did not affect the enforceability of the guarantee. It further held that formal rectification was not necessary given the clarity of the parties’ intention and the availability of correction by construction.

Accordingly, the guarantee secured the Defendant’s liability for the Principal Debtor’s borrowings up to €8 million plus interest. The Court also addressed the timing and circumstances of signing but found no sufficient grounds to invalidate the guarantee on those bases.

Holding and Implications

The Court rendered judgment in favor of the Plaintiff, holding that the guarantee dated 9th April 2008 is enforceable despite the misnomer of the bank’s name.

Holding: The guarantee is valid and enforceable against the Defendant for the sums owed by the Principal Debtor under the loan facility.

The Court awarded judgment for a total sum of €8,225,171.84, comprising principal, interest, and amounts related to a separate overdraft facility. Interest was ordered payable from the date of judgment perfection until payment. The Court declined a stay pending appeal due to lack of arguable grounds and exercised discretion to deny costs to the Plaintiff, noting the litigation arose from an avoidable error and reflecting on broader lending failures.

There are no indications that this decision sets new legal precedent beyond affirming established principles on contract construction and rectification in the context of misnomers in guarantees.
