The Director of Public Prosecutions v Flanagan (Approved)
Factual and Procedural Background
Respondent was arrested on suspicion of drink-driving after providing two breath samples to an evidenzer. The machine recorded a reading substantially above the statutory limit, and Respondent was convicted under s.4(4) of the Road Traffic Act 2010. Respondent appealed and sought access to the evidenzer for examination by an expert. [1][2][3][4]
The Circuit Court granted inspection facilities, including access to the machine’s hardware and software. Applicant subsequently obtained leave to challenge that decision by judicial review. [5][6][7][8]
Legal Issues Presented
- Whether the Circuit Court made a fundamental error of law in interpreting Oates v Brown as recognising an accused’s entitlement to inspect breath-testing apparatus. [9][10]
- Whether the Circuit Court unlawfully treated that entitlement as requiring inspection at the level sought by Respondent’s expert, thereby fettering its discretion. [9][11][12]
- Whether the Circuit Court failed to consider proportionality, the claimed confidentiality of the software, and the potential cost of the inspection. [9][13][14]
- Whether the Circuit Court failed to give adequate reasons. [9][15]
Arguments of the Parties
Applicant’s Arguments
- Applicant argued that Oates v Brown established, at most, a right to seek inspection, and that relevant observations in the judgment were obiter. [16][17][18]
- Applicant submitted that the Circuit Court conflated a right to seek inspection with a right to inspection at whatever level Respondent’s expert considered necessary. [19]
- Applicant argued that the Circuit Court failed to exercise its discretion properly and did not adequately assess proportionality, including the possible loss of the machine, estimated at approximately €12,000 per machine and potentially €1.032 million nationally. [20][21]
- Applicant relied on a contractual non-disclosure provision preventing disclosure of the software codes and argued that the Circuit Court failed to take this into account. [22]
- Applicant submitted that the Circuit Court gave inadequate reasons. [23]
Respondent’s Arguments
- Respondent argued that the Circuit Court had recognised and exercised a discretion both as to whether inspection should occur and as to its level. [24]
- Respondent submitted that the Circuit Court had properly assessed the oral and documentary evidence, including the expert evidence concerning the necessity of examining the hardware and software. [25][26]
- Respondent argued that the Circuit Court had considered proportionality, the alleged confidentiality restriction, and the cost evidence, and had reached conclusions open to it on the evidence. [27]
- Respondent submitted that Applicant had not demonstrated an error of law sufficiently serious to justify judicial review relief. [28]
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Sweeney v Judge Fahy [2014] IESC 50 | Judicial review concerns lawfulness rather than correctness; where jurisdiction exists, only a sufficiently fundamental error may render the decision unlawful. | The Court applied this distinction to reject an attempt to use judicial review as an appeal on the merits of the inspection decision. [29][30][31] |
| McGonnell v The Attorney General [2007] 1 IR 400 | An accused is entitled to seek inspection of apparatus used to produce a statutory certificate benefiting from a rebuttable presumption. | The Court relied on the case, together with Whelan v Kirby, to explain the importance of inspection as a safeguard. [32][33] |
| Whelan v Kirby [2004] IESC 17 | The statutory presumption was rebuttable, and an accused could apply to inspect the apparatus to investigate its reliability. | The Court treated this principle as supporting the availability of inspection facilities. [32] |
| Oates v Brown [2016] 1 IR 481 | The case recognised, at minimum, an accused’s right to seek inspection and the practical importance of investigating the machine where its printout enjoys a rebuttable presumption. | The Court held that the Circuit Court’s description of a right to inspect was a permissible summary of the relevant dicta and did not show that the judge considered herself automatically bound to order inspection at a particular level. [34][35][36][37][38] |
Court’s Reasoning and Analysis
The proceedings were judicial review proceedings, not an appeal. Because the Circuit Court had jurisdiction, its decision could be quashed only for a fundamental error of law sufficiently grave to deprive it of jurisdiction. [30][31][29]
Applicant had expressly conceded in the Circuit Court that Respondent should receive some inspection facilities. The dispute therefore concerned the extent of inspection, rather than whether inspection should occur at all. [39][40]
The evidenzer’s statutory printout benefited from a rebuttable evidential presumption under ss.13 and 20(1) of the Road Traffic Act 2010. The inspection safeguard was therefore important because it enabled an accused to investigate the reliability of the machine and potentially rebut the presumption. [41][42][43][32][44]
The Court rejected the argument that the Circuit Court had misunderstood Oates v Brown. The Circuit Court had expressly referred to a right to seek inspection, recognised that the matter involved judicial discretion, reserved judgment, and considered the evidence and submissions. These matters demonstrated that it had not treated inspection as an automatic entitlement. [45][46][47]
The Court also rejected the argument that the Circuit Court had automatically equated the right to inspection with the level demanded by Respondent’s expert. The Circuit Court had heard extensive conflicting evidence and was entitled to conclude that examination of the hardware and software was necessary to assess forensic integrity. Its conclusion was open to it on the evidence and was not reviewable merely because Applicant disagreed with it. [48][49][50][51]
The reference to the applicable EU disclosure instrument did not establish an unlawful fettering of discretion. The Circuit Court had considered the competing arguments and had not treated the instrument as requiring inspection at any predetermined level. [52][53]
The software objection did not establish a legal error. The alleged contractual restriction was supported only by an assertion from the relevant public agency, and the contract itself was not produced. The Circuit Court considered the objection and reached a conclusion open to it on the evidence. [13][54][55][56]
The cost issue had also been considered. The Circuit Court addressed the possible effect of removing components and allowed for the parties to return to court if a genuine issue concerning the machine’s viability arose. The High Court held that the Circuit Court was entitled to accept or reject the evidence on this issue. [57][58][59][15]
Finally, the High Court rejected the reasons challenge. The Circuit Court had delivered a substantial reserved judgment explaining what had been decided and why. Disagreement with those reasons did not make them inadequate. [60][61]
Holding and Implications
Applicant failed to establish any fundamental error of law warranting certiorari. The High Court proposed refusing the reliefs sought against the Circuit Court judgment and order. [62][63]
The direct consequence was that the order permitting Respondent’s expert to inspect the evidenzer remained undisturbed, subject to the making of final orders. The parties were invited to provide written submissions on the form of the final order, costs, and related matters, with the case listed for mention on a later date. [64][65]
The opinion did not identify any broader implication or establish a new precedent.
