Mr Chan In Devin Sio, an unregistered barrister of Middle Temple resident in Hong Kong, admitted two charges of professional misconduct. Charge 1 arose from conduct in Hong Kong found by the Hong Kong Barristers Disciplinary Tribunal to be professional misconduct, including dishonestly furnishing untrue/inaccurate information to the Standing Committee on Discipline (for which he had been suspended 45 months, censured, fined HK$2,500 and ordered to pay HK$406,800 costs). Charge 2 was failure to report that Hong Kong regulatory action/disciplinary proceedings to the BSB. The BTAS Tribunal made an express finding that the Respondent was deliberately dishonest and had lied to the Standing Committee. Disbarment was found the only available sanction; no further sanction on Charge 2. Costs of £2,670 awarded to the BSB, and an order made under rE227.3 that he not receive a practising certificate pending appeal.

Duties found breached:

Aggravating factors:

  • Deliberate, calculated dishonesty for self-serving purposes, not a fleeting lapse
  • No remorse or apology demonstrated
  • Concerted attempts to cover his tracks and mislead the Hong Kong tribunal
  • Failure to report until effectively caught out by his own sworn High Court evidence
  • Cavalier attitude to professional duties

Mitigating factors:

  • Admitted both charges before the Tribunal (in contrast to denying charges in Hong Kong)
