"Third-party" or "non-party" discovery is provided for under Irish court rules. It is an extension of the scope of discovery in that it allows the court to order a non-party or stranger to the proceedings to make discovery of documents in certain circumstances.

Basis and Standing

Order 31 Rule 29 of the Rules of the Superior Courts (RSC) governs the procedure in the superior courts, while similar provisions are also contained in the Circuit Court Rules and District Court Rules.

The test applicable to an application for non-party discovery was summarised by the Supreme Court in Edward Keating v Radio Telefís Éireann and Others[2013] IESC 22. The applicant must establish that:

• the third party has or is likely to have in its possession or power of possession documents falling within the parameters of the type of documents sought;
• the documents are relevant to an issue or issues in the action;
• an order for discovery is necessary for disposing fairly of the cause or matter or for saving costs; and
• any order made, by reference to its scope, is not oppressive.

The Supreme Court also emphasised the discretionary nature of the court's jurisdiction in non-party discovery applications.
