Jonathan is the Founder and Managing Director of Tembusu Law. He is also the founder of LawGuide Singapore, a prominent legaltech startup which successfully created and launched Singapore’s first legal chatbot in 2017.

He graduated from the University of Bristol (UK) in 2002 and was called to the Bar of England and Wales (Gray’s Inn) in 2003 and also admitted as an Advocate & Solicitor of the Supreme Court of Singapore. Prior to founding Tembusu Law, Jonathan was a Partner in a leading homegrown Singapore Law Practice where he helped to drive innovation and strategy and had oversight of internal functions including organisational development, talent management, regional and international business growth and strategic partnerships.

He has a broad and varied general practice dealing with both contentious and non-contentious areas of law. He was formerly a Prosecutor in the Attorney-General’s Chambers and the Ministry of Manpower, and he is experienced in civil and criminal litigation and dispute resolution matters, having represented clients for a diversity of cases at all levels of the Singapore Courts and also participated in proceedings conducted under the Arbitration Rules of the International Court of Arbitration at the International Chamber of Commerce Centre (ICC).

Civil and Regulatory Litigation Matters

Some of the civil and regulatory litigation matters in which Jonathan is retained on an on-going basis include the following: –

  • Advising and acting for an established Grade A1 Building and Civil Engineering builder in Singapore in respect of contractual, work injury and employment issues and disputes.
  • Advising and acting for a statutory board in respect of the prosecution of regulatory offences relating to the energy sector in Singapore.

Criminal Prosecution

During his time at the Attorney-General’s Chambers, Jonathan was also a part of the successful prosecution team for high-profile cases such as Public Prosecutor v Vidya Shankar Aiyar [2003] SGDC 327 and Public Prosecutor v Chan Cheng Khoon (2004; unreported) (the Everitt Road neighbours’ dispute case).

In addition, Jonathan has conducted trials involving offences under the Penal Code, Misuse of Drugs Act, Workplace Safety and Health Act, Employment Act, Employment Agencies Act and the Employment of Foreign Manpower Act, including the prosecution of a large-scale case lasting more than 40 days of trial concerning the illegal employment and deployment of foreign workers by a syndicate.

Criminal Defence

Notably as Defence Counsel, Jonathan received recognition from the Ministry of Foreign Affairs and Trade of the Republic of Korea in 2012 for his dedication and professionalism in advising and acting for a Korean national who was charged in the Singapore Courts with drug-trafficking offences which carried the death penalty.

Some of the cases in which Jonathan has been involved in as Defence counsel include the following: –

  • Acting for a former Director of a publicly listed offshore rig and ship building company who was charged in relation to multiple offences under the Prevention of Corruption Act. Jonathan helped to successfully persuade the Prosecution to withdraw all charges against the accused person.
  • Acting for a client charged with theft. Although the accused person had a substantial record of previous convictions relating to similar offences, Jonathan successfully argued for a Mandatory Treatment Order to be made under the Criminal Procedure Code in lieu of imprisonment on the basis of her severe mental health and behavioural conditions.
  • Acting for a National Serviceman charged with causing grievous hurt by a rash act in relation to an incident which occurred during a training session. Jonathan helped to successfully persuade the Prosecution to amend the original charge carrying a usual sentencing tariff of detention to a significantly less-serious charge for a non-registrable offence for which only a fine was subsequently imposed.
  • Acting for a foreign exchange student in Singapore investigated for the outrage of modesty of a woman. Jonathan helped to successfully persuade the investigators to issue a warning in lieu of prosecution.
  • Acted for a foreign business owner in Singapore investigated for multiple offences relating to the illegal employment of foreign manpower. Jonathan helped the client to successfully persuade the investigators and the relevant authority to only take administrative action in lieu of prosecution.
  • Acting for the founder of a hygienic products manufacturing company who was charged in relation to offences under the Prevention of Corruption Act. Jonathan helped to successfully persuade the Prosecution to withdraw all charges against the accused person.
  • Acting for a Korean national charged in relation to the exportation of drugs from Singapore. Jonathan helped to successfully persuade the Prosecution to amend the original charge carrying the mandatory death penalty to a significantly less serious charge for which only a period of imprisonment was subsequently imposed. The accused person has since completed his sentence of imprisonment and returned to his home country.

Corporate & Commercial Law

In addition to his domain expertise in handling litigation work, Jonathan is also experienced in advising on and coordinating corporate and commercial transactions including in relation to startups, family offices and investment holding companies, equity offerings, share acquisitions and disposals, joint ventures as well as mergers & acquisitions.
