WANG YUNHE v ATTORNEY-GENERAL

Facts

Mr Wang Yunhe was indicted in the US District Court for the Eastern District of Texas for conspiracy to commit computer fraud, aiding and abetting computer fraud, conspiracy to commit wire fraud and conspiracy to commit money laundering. The US alleged he developed malware to infect residential computers worldwide and sold customers access to the compromised network's IP addresses, which they used to hide their identities while committing crimes. On 14 February 2024 the US asked Singapore's Minister for Law for his extradition and for seizure of related articles. He was arrested on 24 May 2024, and the police seized bank cards, phones, drives, a laptop and a computer from his home.

Before the committal hearing, he asked the District Judge, sitting as a Magistrate under the Extradition Act 1968, to rule the seizure unlawful and to order the State to provide the originals or other primary evidence of documents it would rely on. Both applications were dismissed. In Originating Application No 969 of 2025 he sought permission to apply for quashing orders against those decisions.

Issues

1. Whether the Magistrate's decisions under the Extradition Act were susceptible to judicial review
2. Whether the applicant had to exhaust the alternative remedy of revision before seeking judicial review
3. Whether the challenge to the documents ruling was premature and whether the application was an appeal in disguise

Holding

The High Court (Chua Lee Ming J) dismissed the application for permission to seek judicial review and ordered the applicant to pay costs fixed at $8,000 including disbursements. The applicant has appealed.

Reasoning

The court held that the Magistrate was acting judicially as a court, not as a separate statutory tribunal, but the parties came to agree that her decisions were reviewable because a Magistrate's court is an inferior court. Permission still required an arguable case of reasonable suspicion, and the applicant fell short.

First, judicial review is a remedy of last resort. The High Court's broad supervisory and revisionary jurisdiction over subordinate courts under s 27 of the Supreme Court of Judicature Act 1969 was available, with nothing to exclude extradition proceedings, and he had not used it.

Second, the challenge to the documents ruling was premature. The seizure ruling was a stand-alone decision, but the documents ruling was interlocutory to the committal hearing, and he could raise it in a review under s 17 of the Act if he was committed. None of the exceptions applied: access to documents would be dealt with at the committal case conference, so there was no real risk of irreparable harm or wasted costs, and novel questions of law are not enough on their own; the issue was one of timing.

Third, both challenges were appeals in disguise. The Magistrate had expressly summarised and rejected his arguments on the seizure, and his complaint that she ignored them was described as mischievous and made in desperation. On the documents, the Evidence Act argument had not actually been put to her, and her reasons on the efficiency of extradition proceedings and the trial in the requesting country being the proper forum for production showed she had weighed his case management point. Whether her decisions were correct was not a matter for judicial review.
