Riordan v. An Taoiseach

Factual and Procedural Background

The Applicant previously litigated two sets of proceedings against the Respondents (Record Nos. 381/97 and 108/99). Both actions were dismissed—first by the High Court and then, on appeal, by the Supreme Court. Although an earlier order prohibited the Applicant from initiating fresh proceedings against the same parties without leave, he nevertheless filed three new motions in the concluded Supreme Court matters: two seeking to set aside the earlier Supreme Court judgments and one seeking discovery to support those efforts. The Respondents, in turn, filed a fourth motion requesting that the Applicant’s motions be struck out as an abuse of process.

Legal Issues Presented

1. Whether the Supreme Court has jurisdiction to reopen and set aside its own final judgments at the behest of a dissatisfied party.
2. Whether the Applicant’s motions constitute an abuse of the process of the Court warranting a stay or strike-out.
3. Whether alleged bias or “corruption” on the part of individual judges—raised without supporting evidence—creates a basis to revisit the earlier judgments.

Arguments of the Parties

Applicant's Arguments

• The earlier Supreme Court judgments contain fundamental legal and constitutional errors amounting to a “repudiation of the Constitution.”
• The size and nature of the alleged errors demonstrate judicial corruption and bad faith.
• Certain members of the Court (e.g., Judge Costello and the former Chief Justice) had interests—such as prior involvement in divorce legislation or tribunals—that rendered them incapable of impartial judgment.

Respondents' Arguments

• The issues have already been fully litigated; the Applicant has exhausted his judicial remedies.
• No legal mechanism exists to reopen final Supreme Court decisions by way of motion in the same proceedings.
• The new motions are frivolous, vexatious, and an abuse of process.

Court's Reasoning and Analysis

The Court affirmed its inherent jurisdiction to prevent abuse of process, referencing Barry v. Buckley. Even accepting the Applicant’s allegations of error at face value, the Court emphasized that Article 34.4.6 of the Constitution makes Supreme Court decisions “final and conclusive,” a principle designed to secure the finality of litigation and the proper administration of justice. Re-litigating settled issues would undermine both.

On the bias allegations, the Court held that a judge’s prior exercise of judicial or statutory functions does not create a disqualifying interest. The Applicant provided no rational or evidential basis for claims of judicial corruption or partiality; those assertions were deemed “manifestly ill-founded and bound to fail.”

Accordingly, the Court concluded that the Applicant’s motions seeking to revisit the prior judgments are “clearly bound to fail” and amount to an abuse of process. The related discovery motion therefore served no purpose.

Holding and Implications

The Court stayed the Applicant’s motions as an abuse of process, struck out the associated discovery motion, prohibited any further motions in these proceedings without leave of the Court, and awarded costs to the Respondents.

Implications: The decision reinforces the constitutional and common-law principle of finality in litigation, underscoring that the Supreme Court will not entertain efforts to reopen concluded cases absent a recognized legal basis. It also signals the Court’s readiness to curb repetitive or vexatious applications by imposing leave requirements and cost sanctions.
