Jason Yu

  • BA in Jurisprudence, University of Oxford (First Class)
  • BCL, University of Oxford (Distinction)
  • CEDR Accredited Mediator


Jason graduated from the University of Oxford in 2009 with First Class Honours, ranking first in his class in Contract Law and ninth overall. In 2011, he obtained a Distinction in his BCL degree at Oxford and was awarded the Bar Scholarship. He joined Chambers in the following year.

Since joining Chambers, Jason has developed a broad practice with a particular focus on commercial, company, insolvency and intellectual property litigation. He is also regularly instructed to act as counsel in arbitrations and related court applications.

Jason is an experienced advocate in his own right, including in trials, appeals and arbitration hearings. He has been instructed by professionals and financial institutions to act as sole counsel in a range of disputes, from securing the discharge of an injunction against a global investment bank to obtaining a disclosure order for one of the largest Chinese insurance companies in a passing-off case.

He has also been led as a junior in notable high value disputes, such as the Bank of East Asia litigation (on behalf of Elliott Advisors), the China Forestry litigation (on behalf of KPMG), the Nan Fung probate litigation (on behalf of a beneficiary), the Convoy Global litigation (on behalf of directors), the China Shanshui litigation (on behalf of a state-owned enterprise) and the Ablyazov litigation (on behalf of BTA Bank).

Jason is often involved in cases with a cross-border or conflict of laws element. Of particular note is the Court of Final Appeal case of Ryder v Timely, where Lord Collins NPJ delivered one of the leading judgments in the common law on foreign illegality.

He was recognised by Chambers & Partners Asia Pacific as "a complete star at his level" and “a leading, outstanding junior member of the Hong Kong Bar”, and was noted for his “talent and extensive experience”, “very powerful advocacy” and "really unrivalled knowledge of the law". Who’s Who Legal has also highlighted “his superb litigation practice and strong expertise in company law, insolvency and IP”.
