HKSAR v. TAN CHIN TENG

Citation

[2025] HKCA 179
Court

Court of Appeal
Case number

CACC61/2024

Leave to appeal out of time was refused because the judge had correctly applied sentencing guidelines: the applicant and co-defendant were properly classified as storekeepers, starting points and a justified enhancement for coming to Hong Kong were correctly applied, and the reductions for cooperation and guilty plea were lawfully calculated; the applicant's comparative disparity complaint lacked factual and legal foundation.

Citation

[2019] HKDC 889
Court

District Court
Case number

DCCC718/2017

Applying the objective fair‑minded and informed observer test, the judge found no firmly established real possibility of bias arising from his prior conduct at the co‑defendant's plea; however, because the prosecution subsequently joined the defence application and to avoid further delay and costs, the judge granted leave to recuse himself and vacated and refixed the trial dates.

Citation

HKSAR v. CHEUK YUNG KAN AND ANOTHER
Court

Court of Appeal
Case number

CACC203/2007

The judge correctly adopted a 3‑year starting point for domestic burglary; the 1st applicant's application for leave to appeal sentence and his request for adjournment were refused as not justified and unfair to co‑defendants; the 2nd applicant, despite inconsistencies, was entitled to some additional discount for cooperation and giving evidence and his sentence was reduced from 24 to 21 months.

Citation

HKSAR v. GUILLERMO, MILAGROS COSTALES
Court

Court of First Instance
Case number

HCMA1166/2005

Although the learned Magistrate was entitled to impose immediate custody given the seriousness of the offence, the Court allowed the appeal on humanitarian and situational grounds — pregnancy, health concerns, clear record, delay in charging and cooperation with authorities — and substituted the immediate custodial sentence with a three month sentence suspended for two years in the special circumstances of the case.

HKSAR v. KWONG SHING CHEONG STEPHEN

Citation

HKSAR v. KWONG SHING CHEONG STEPHEN
Court

Court of Appeal
Case number

CACC555/2002

The Court refused leave to appeal and upheld the two-year sentence because the offences were serious, involved three transactions totalling about $7.8 million, and the applicant was not entitled to additional discount for an unfulfilled promise to testify; the sentencing judge acted within acceptable bounds and the sentence was not manifestly excessive.

HKSAR v. CHU KA SHING

Citation

HKSAR v. CHU KA SHING
Court

Court of Appeal
Case number

CACC104/2001

The court held that a 24-month starting point was justified because of implied threats and courtroom intimidation, but the applicant was entitled to a 50% overall discount reflecting guilty plea, prior cooperation and that his evidence was instrumental in securing the foremans conviction; given impracticality of clemency, leave to appeal out of time was granted and the sentence was reduced from 15 months to 12 months imprisonment.

HKSAR v. FAN CHI KEUNG

Citation

HKSAR v. FAN CHI KEUNG
Court

Court of Appeal
Case number

CACC248/1997

The trial judge correctly set an 11-year starting point for trafficking 161.66 grams of heroin hydrochloride, properly allowed a four-year reduction for the guilty plea and cooperation relevant to the prosecution of the co-defendant, and correctly refused to credit information about third parties that predated the offence; therefore the seven-year sentence was not excessive and the application for leave to appeal is refused.

R. v. YAN IM KUN

Citation

R. v. YAN IM KUN
Court

Court of Appeal
Case number

CACC680/1996

Where an offer to give evidence was genuine but rendered unnecessary by co-accused pleading guilty, and where the offer likely influenced those pleas, the offender is entitled to a reduction in sentence; accordingly the Court reduced the sentence from six years to five years while confirming the need to apply the standard guilty-plea discount in normal cases.

R v. CHUN YEUNG

Citation

R v. CHUN YEUNG
Court

Court of Appeal
Case number

CACC89/1995

The court exercised its discretion to grant a limited adjournment—to enable the police to explore the applicant's prospective cooperation—but refused to adjourn the hearing indefinitely pending the completion of any future criminal proceedings; the hearing was adjourned to be listed as soon as convenient after 1 March 1997 and marked not part-heard, balancing public interest in expedition against potential relevance of cooperation to sentence and confiscation order.

R. v. KO WING SHING

Citation

R. v. KO WING SHING
Court

Court of Appeal
Case number

CACC720/1995

The Court held that the 9‑year starting point was at the top of the proper range but not outside it; however, because the applicant had shown genuine cooperation unknown to the trial judge he was entitled to additional credit, and the sentence was reduced from six years to five years.
