Popoviciu v Curtea De Apel Bucharest (Romania)

Factual and Procedural Background

The Appellant (the Romanian judicial authority) issued a European Arrest Warrant (“EAW”) on 3 August 2017 seeking the extradition of Respondent, who had been convicted in Romania of offences related to the allegedly unlawful transfer of state-owned land and associated bribery. After hearings in the Westminster Magistrates’ Court, District Judge Zani ordered extradition on 12 July 2019.

The High Court allowed the Respondent’s appeal on 11 June 2021, discharged him and quashed the extradition order, holding that fresh evidence raised “substantial grounds for believing” there was a real risk that his Romanian trial had been flagrantly unfair. A point of law was certified, and permission to appeal was ultimately granted by the Supreme Court.

Argument was heard in May 2023. After the hearing, the designated authority notified the Supreme Court that the EAW had been withdrawn. Pursuant to s. 43(4) of the Extradition Act 2003, the Supreme Court dismissed the appeal on 24 July 2023 but nevertheless delivered judgment to answer the certified question and clarify the law.

Legal Issues Presented

1. In a conviction extradition case, must a requested person prove on the balance of probabilities that his prior foreign trial was a flagrant denial of Article 6 ECHR rights, or is it sufficient to show “substantial grounds for believing” there is a real risk that it was flagrantly unfair?
2. Whether an exception to the usual standard of proof should be extended beyond evidence obtained by torture to encompass allegations of judicial corruption or bias.
3. Whether, if extradited, the Respondent would have an effective remedy in Romania to challenge the legality of his detention in light of the alleged unfairness.

Arguments of the Parties

Appellant's Arguments

• The High Court applied the wrong standard; past events (the Romanian trial) must be proved on the balance of probabilities, not assessed on a forward-looking “real risk” basis.
• The exception recognised by the European Court of Human Rights (“ECtHR”) for evidence obtained by torture is unique and should not be extended to corruption/bias allegations.
• The Respondent failed, on the evidence, to prove that his trial was in fact flagrantly unfair.
• Romanian law provides procedures (extraordinary appeal/revision and possible constitutional avenues) capable of remedying any injustice, so Article 5 concerns are unfounded.

Respondent's Arguments

• Fresh evidence admitted by the High Court showed a “real risk” that the trial judge had a corrupt, undisclosed relationship with a key prosecution witness, vitiating the trial.
• Imposing a balance-of-probabilities burden is inappropriate where corruption is inherently difficult to prove and the State alone controls much of the evidence.
• The ECtHR’s reasoning in Othman (torture evidence) should be extended to corruption/bias cases because of their seriousness and evidential difficulties.
• Romania offers no effective post-conviction remedy if the allegations are true; extradition would therefore breach Articles 5 and 6.

Court's Reasoning and Analysis

1. Past fact vs. future risk. Referencing domestic authorities such as Mallett, Fernandez and In re B, the Court held that determining whether a past trial was flagrantly unfair requires proof on the balance of probabilities; the “substantial grounds/real risk” test is reserved for future events (e.g. accusation warrants or post-extradition treatment).

2. Consistency with Strasbourg jurisprudence. Reviewing Soering, Ahorugeze, and many subsequent ECtHR cases, the Court found that, save for the narrow Othman torture-evidence exception, Strasbourg requires alleged past violations to be proved, normally “beyond reasonable doubt” in its own lexicon. The High Court’s “real-risk” approach therefore diverged from both UK and ECtHR authority.

3. Rejection of a new corruption/bias exception. The Respondent argued that allegations of judicial corruption warrant the same relaxed standard as torture evidence. The Supreme Court declined, reasoning that torture occupies a uniquely abhorrent position in international law (jus cogens) and that no Strasbourg decision supports extending the exception to corruption or bias.

4. Fresh-evidence framework. Applying Fenyvesi, further material proffered by the Respondent (statements from additional Romanian witnesses) did not satisfy the criteria of unavailability or decisiveness; therefore, even had the EAW remained live, remittal for that purpose would have been refused.

5. Prospective remedy in Romania. The Court acknowledged an arguable question whether Romanian procedure offers an effective mechanism to challenge detention if undisclosed judicial bias is later discovered. Were the warrant still in force, this discrete issue would have been remitted to the High Court for factual determination, consistent with Article 5(4) as explained in Etute.

Holding and Implications

DISMISSED (statutory dismissal following withdrawal of the European Arrest Warrant).

Although the appeal was dismissed procedurally, the Supreme Court answered the certified question: in conviction-based extradition requests, a requested person must prove on the balance of probabilities that a flagrant denial of Article 6 occurred; showing a mere real-risk is insufficient, save for the established torture-evidence exception. The judgment clarifies the applicable standard across UK extradition cases and rejects extension of the Othman exception to alleged judicial corruption or bias. No new precedent on remedies was set because the warrant’s withdrawal mooted further directions, but the Court signalled that effective post-conviction remedies in the requesting state remain an important consideration under Articles 5 and 6.
