Company & Insolvency
- Arboit v Koo Siu Ying (No. 2)  3 HKLRD 154. Yang (leading Kaiser Leung) continued to act for the liquidators in the finale to these proceedings where Queeny Au-Yeung J., having earlier found the Defendants guilty of contempt in  HKEC 556, thoroughly reviewed the authorities on and the approach to be adopted by the courts in imposing punishment for civil contempt.
- Arboit v Koo Siu Ying  3 HKLRD 319. Yang (led by Mark Strachan Q.C., S.C.) successfully refuted accusations of abuse of process and oppression that had been levelled against a liquidator who had brought contempt proceedings arising out of orders made under s. 221 of the previous Companies Ordinance (CAP. 32).
- Re Hang Heung Cake Shop Co Ltd  HKEC 163. Yang obtained leave for the shareholders of 2 companies to proceed with a statutory derivative action for abuse of confidence, undue influence, and unconscionable conduct against, inter alia, the companies' former solicitors. The Judgment of Le Pichon DHCJ. is instructive as regards locus standi to bring such applications.
- Max Regent Garments Co Ltd. v Direct Fashion Sourcing Ltd.  HKEC 1368. The Court refused applications by a creditor for invalidation of various resolutions or the removal of the Liquidators (who were represented by Yang). Barma J.'s judgment is the leading decision on the appropriate form of resolutions for voluntary liquidations, as well as on requirements that have to be met in order for a document or information to be "laid before" a meeting.
- Akai Holdings Ltd. (in compul liq) v Everwin Dynasty Ltd. & ors.  4 HKLRD 248;  3 HKC 485. Yang (led by Mark Strachan) appeared for James Ting in this case which concerned the correct approach to take where an application to amend pleadings which might prejudice a potential limitation defence. This was the first time the Court of Appeal considered and contrasted the approach espoused by the Hong Kong Court of Appeal in Extramoney Ltd. v Chan, Lai, Pang & Co.  1 HKLR 244), with that subsequently set out by the English Court of Appeal in Welsh Development Agency v Redpath Dorman Long Ltd.  1 WLR 1409.
- Re Legend International Resorts Ltd.  HKEC 221. The liquidators of the company applied for security for costs in relation to an application for directions as to the conduct of the liquidation, including their removal. Yang acted on behalf of a creditor and contributory in opposing the said application, which was the first of its kind in Hong Kong.
- Re Legend International Resorts Ltd.  HKEC 317. Appeared (led by Anson Wong) on behalf of a creditor and contributory applying for directions as to the conduct of this liquidation, which was subject to a regulating order. An important case on post-regulating order directions, and the only case to consider whether a regulating order can be varied or discharged.
- Re Wickson Holdings Ltd.  2 HKLRD 373. Appeared for a group of shareholders to seek directions regarding the disposal of the company’s major assets. The Court had regard to the commercial reality of the situation and granted the desired directions in spite of the application being fiercely contested by a rival camp of shareholders.
- GDH Ltd. v CreditorCo Ltd.  HKEC 1238 (CFA),  HKEC 818 (CA),  5 HKLRD 895 (CFI). Appeared (led by Chua Guan-Hock S.C.) at all levels of these proceedings, which arose out of a US$4.9 billion debt restructuring scheme, the main concern being who would receive payment of US$23 million worth of assets. The leading case on whether and how far good faith applies in relation to debt restructuring agreements, and also an important case on service out of the jurisdiction.
- AXA China Region Insurance Co Ltd. v Lin Kwai Ying Katie  2 HKLRD 1139. Chung J. granted the Defendant's (represented by Yang) application to strike out a defective Statement of Claim in this employment dispute. The Judgment contains useful observations on pleading the tort of causing loss by unlawful means and examined pressing issues relating to the extent of the Labour Tribunal's jurisdiction.
- Re FAR  2 HKLRD 1166. Albert Wong J. rejected the Applicant’s application for judicial review of the decisions of the Director of Immigration (represented by Yang) and of the Torture Claims Appeals Board under the Unified Screening System. The judgment is an instructive example of how the Courts approach the question of alleged mental suffering, as well as the concept of extended state acquiescence given the test set out by the Court of Appeal in AM v Director of Immigration  1 HKC 416.
- Secretary for Justice v Commission of Inquiry on Allegations relating to the Hong Kong Institute of Education  4 HKLRD 11,  3 HKC 102. Appeared (led by Michael Beloff Q.C. and Johnny Mok S.C.) on behalf of the Secretary of Justice, the former Secretary for Education and Manpower, and the former Permanent Secretary for Education and Manpower, in this leading case which examined and defined the relationship between academic freedom and the freedom of expression, with a particular emphasis on the rights and responsibilities of senior government officials when dealing with academics.
- Inquiry on Allegations relating to the Hong Kong Institute of Education. Yang was led by Johnny Mok S.C., Lisa Wong S.C., and Thomas Au (now Au J.) in this high-profile 35-day inquiry which arose out of allegations that the Secretary for Education and Manpower, and the then-Permanent Secretary for Education and Manpower, had interfered with the academic freedom and institutional autonomy of higher education institutions. The report led to subsequent groundbreaking judicial review proceedings in which Yang was also involved.
