Holding

The Court of Appeal allowed the appeal. It held that seizure of the appellants' computers upon arrest may have been lawful, but searching and forensically extracting data from them while in state custody, without obtaining a search warrant from a magistrate as required by section 28 of the Computer Misuse Act, violated article 27 of the Constitution. URA officers were not 'authorised officers' under the Act, and section 7 of the EACCMA conferred no such power for a Computer Misuse Act charge. The illegally obtained electronic evidence formed the core of the prosecution case and was excluded. As a retrial was impracticable after roughly ten years, the convictions and sentences were set aside and the appellants acquitted.

Facts

The appellants were among persons arrested on 19 June 2012 near URA premises, suspected of hacking into the URA computer system. URA enforcement officers (not police) impounded their vehicle and seized laptops, an external hard drive, a flash disk and phones, without a search warrant. The seized computers were later subjected to forensic analysis using Encase software, generating mirror images and reports tendered as exhibits. Investigations had begun around March 2011. The appellants were indicted on six counts under the Computer Misuse Act 2011 and the EACCMA, convicted on five counts and sentenced to terms of imprisonment and a fine. After an earlier appeal led to an order for retrial which the Supreme Court set aside (reinstating the High Court conviction), the Court of Appeal heard the outstanding grounds on the merits. The computers were not returned within 72 hours and no search warrant was obtained to examine their contents, which formed the core of the prosecution evidence.

Issues

  1. Whether electronic evidence seized from and extracted from computers without a search warrant, contrary to section 28 of the Computer Misuse Act and article 27 of the Constitution, was admissible.
  2. Whether failure to disclose the Encase forensic software tool and mirror images to the defence occasioned a miscarriage of justice.
  3. Whether the trial was a nullity because assessors did not take the oath of impartiality as required by section 67 of the Trial on Indictments Act.
  4. Whether convicting the appellants under both the Computer Misuse Act and the EACCMA amounted to double jeopardy.
  5. Whether the URA officers were authorised under section 7 of the EACCMA to conduct the search and seizure under the Computer Misuse Act.
  6. Whether ordering a retrial was appropriate given the time the appellants had spent in custody.

Orders

  • Ground 1 of the appeal allowed.
  • Appeal against conviction and sentence allowed.
  • Appellants acquitted.
  • Appellants to be set free unless held on other lawful charges.

Key headnotes

Criminal Evidence — Electronic Evidence — Search and Seizure of Computers Without a Warrant
While computers and electronic devices may lawfully be seized upon arrest, searching and extracting data from them while in state custody requires a separate search warrant under section 28(3) of the Computer Misuse Act; evidence so extracted without a warrant is unlawfully obtained and inadmissible.
Right to Privacy — Article 27 — Unlawful Search of Property
A search of seized computers conducted without judicial authorisation, where there was sufficient time to obtain a warrant, is an unlawful search forbidden by article 27 of the Constitution and is not justifiable under article 43 as the exigencies of the situation had ceased once the items were in state custody.
Computer Misuse Act — 'Authorised Officer' — Powers of URA Officers
An 'authorised officer' under section 28(9) of the Computer Misuse Act is a police officer holding a warrant; URA enforcement officers exercising powers under section 7 of the EACCMA cannot conduct searches and seizures under the Computer Misuse Act, which is a national law governed solely by its own terms.
Criminal Evidence — Illegally Obtained Evidence — Exclusion Where Core of Prosecution Case
Where unlawfully obtained electronic evidence forms the foundation of the prosecution case, its exclusion renders consideration of evidence evaluation and inconsistencies unnecessary, as the remaining evidence has no independent foundation.
Retrial — Discretion — Lapse of Time and Prejudice to Accused
An appellate court may decline to order a retrial where, given the lapse of time and the period already spent in custody, ordering one would be impracticable and prejudicial to the accused.
