HKSAR v. CHUNG LAI TUNG

Citation

[2026] HKCA 210
Court

Court of Appeal
Case number

CACC62/2023

The court granted an extension of time because refusal would have shut out a substantial and plainly arguable ground of appeal where the applicant was sentenced after 18 September 2018; the revised guidelines in Huang Ruifang (No 3) apply and require recalculation of the starting point and application of the same enhancements and discounts previously afforded, resulting in reduction of the sentence to 10 years 7 months' imprisonment.

HKSAR v. SHING YIU FUNG

Citation

[2026] HKCA 199
Court

Court of Appeal
Case number

CACC142/2025

Bail pending appeal was granted because the court gave leave to appeal on substantial and plainly arguable grounds and concluded there was a real possibility the sentence would be reduced (by increasing the guilty plea and assistance discounts) such that the applicant's immediate release would be warranted.

HKSAR v. WONG SAI MAN SIMON

Citation

[2025] HKCA 747
Court

Court of Appeal
Case number

CACC251/2024

The judge did not err: the combined approach to cocktail drugs was properly applied using ketamine as the base and enhancing for cocaine; the two offences were separate occasions with different facts so a partly consecutive sentence was justified; the totality principle and guilty plea discount were correctly applied; accordingly leave to appeal against sentence was refused.

HKSAR v. LAU SIU FUNG

Citation

[2025] HKCA 375
Court

Court of Appeal
Case number

CACC206/2024

Leave to appeal against sentence was granted because there is a legitimate and arguable basis that the sentencing judge erred: the starting point adopted for Counts 1 and 3 may have been manifestly excessive and the imposition of a consecutive element for Count 2 may have failed to account adequately for overlapping criminality; consequently the appeal merits full hearing and is to be heard together with Au Chun Wah.

Citation

[2025] HKCA 244
Court

Court of Appeal
Case number

CACC20/2024

Leave to appeal against sentence was granted because the prosecution conceded the value of the applicant's assistance and the full Court should determine the appropriate sentencing discount in light of any continuing assistance.

HKSAR v. KHALIQ SALMAN (aka KHALIA SALMAN)

Citation

[2024] HKCA 1084
Court

Court of Appeal
Case number

CACC131/2023

The Court held that, on the material before it, the appellant's information and expressed willingness to testify were of practical use despite the police assessment to the contrary; because the Yeung Hoi Ting procedure had not been properly followed and there was cogent independent evidence supporting the appellant's account, the court intervened and awarded a six‑month discount, reducing the sentence from eight years to seven years and six months.

HKSAR v. X

Citation

[2024] HKCA 1168
Court

Court of Appeal
Case number

CACC193/2022

The appellant's information was of practical use notwithstanding the absence of arrests because it led to the interception of a substantial consignment of dangerous drugs matching his particulars and provided intelligence about smuggling methods and persons involved; therefore a sentencing discount was warranted and, on assessment of the assistance and its consequences, the appropriate reduction was 1 year and 6 months, reducing the sentence from 18 years to 16 years 6 months imprisonment.

HKSAR v. LI FUCHAO AND ANOTHER

Citation

[2024] HKCA 732
Court

Court of Appeal
Case number

CACC189/2021

The Court held that both applicants provided practical, useful and truthful assistance that led to the arrest and conviction of a co‑accused; there was no evidence of real or ongoing risk to the applicants or their families; such assistance justifies a 50% total discount, and therefore the sentences were reduced accordingly.

HKSAR v. LAM SIU SANG

Citation

[2024] HKCA 206
Court

Court of Appeal
Case number

CACC135/2022

Leave refused because the sentencing judge did not err: the prosecution had properly assessed the applicant's information as of no practical use and of questionable credibility, any discount was discretionary, the judge was generous in awarding 4 months and an appellate court will not reweigh such assessments absent procedural error or misapplication of law.

HKSAR v. THAPA KRISHNA KUMAR

Citation

[2023] HKCA 1332
Court

Court of Appeal
Case number

CACC128/2023

Leave to appeal was refused because the sentencing judge’s assessment of mitigation and the extra 2% discount for assistance was within her wide discretion, the mistaken factual remark about timing of the prior conviction did not result in prejudice or reduce the discount, and the applicant’s family circumstances did not warrant further reduction.
