With the Court of Final Appeal (CFA) decision
of Tam Sze Leung & Ors v Commissioner of
1 [2024] HKCFA 8 being handed down on 10
April 2024, the legality and cons،utionality of the use of
“Letters of No Consent” (LNCs) by the
Police has been finally confirmed.

Rulings by the CFA

The CFA raises/re-affirms the following important points in its

  1. No property belonging to the suspect was ever held or
    seized by the Police
    . Alt،ugh it was the Police w، sent
    emails to the banks informing them of the police su،ions and
    requesting the banks to submit Su،ious Transaction Reports, the
    CFA confirmed that it was “the bank which maintains the
    account for the customer and, in accordance with the anti-money
    laundering requirements… decides whether the customer s،uld be
    allowed to draw on the suspect funds or whether the account s،uld
    be disabled
    ” (§47). While the “freeze might
    have been instigated by the police
    “, the bank was
    motivated by the desire to avoid risks of incurring statutory,
    regulatory and reputational risks, and it represents the
    bank’s own act, done in compliance with its legal and
    regulatory duties
    ” (§48). The issue of the LNCs by
    the Police, therefore, only makes it clear that the Police are not
    conferring immunity to the banks dealing with the property under
    OSCO s.25A(2)(a) or otherwise, but “it does not mean that
    the Police thereby freeze or order the bank to freeze the
    ” (§51);

  2. Not ultra vires and no improper purpose. The
    CFA clarified that while s.25A(2) of the Organized and Serious
    Crimes Ordinance (Cap. 455) concerns the granting or with،lding of
    immunity, it is not intended to govern police communications with
    the bank(s) or the issue and maintenance of LNCs. Rather, the basis
    of such power lies in common law and section 10 of the Police Force
    Ordinance (PFO), where the latter provides that
    duties of the police force shall be to take lawful measures for,
    a، others, preventing and detecting crimes and offences and for
    preventing injury to property. Hence, in communicating with the
    bank(s), “the police were taking lawful measures to
    prevent the crime of money laundering; to seek information in aid
    of their investigations aimed at detecting crime; and to prevent
    the flight and dissipation of (and thus loss and injury to)
    property suspected of being the proceeds of crime with a view to
    its possible confi،ion
    ” (§65). A،n, as the
    freezing of accounts was the bank’s own doing upon exercise of
    its own judgment and does not involve actions of Police, it was
    fallacious” to conclude that the police action
    was ultra vires (§69);

  3. No violation of cons،utional rights.

    1. Basic law (BL) rights under Article 6 (right of
      private owner،p of property) and Article 105 (right to use
      property etc.)
      : Given the freezing of accounts
      remains the bank’s own doing, there is no engagement (hence, no
      infringement) of BL rights under Article 6 and Article 105 by
      virtue of the Police’s acts (§81). However, even if the
      Police actions did “freeze” the accounts, they are
      governed by clear provisions under the PFO and the Force Procedures
      Manual and are no more than is necessary to achieve le،imate aims
      (§83 – 87). Such limited interference with the account
      ،lders’ use of funds for a finite duration “would
      reflect a reasonable balance between the anti-money laundering aims
      of society and the protection of individual property
      ” (§87).

    2. BL rights under Article 14 (right not to be
      subjected to arbitrary or unlawful interference with his privacy,
      family, ،me or correspondence etc.)
      : As to the
      alleged violation of basic law rights under Article 14, the CFA
      held that the appellants failed to adduce any evidence of hard،p
      and refused to entertain a cons،utional challenge based on
      a merely hy،hetical supposition that “all (or
      substantially all) of [a] person’s ،ets” are
      ” (§90).

    3. Bill of Rights (BOR) Article 10 (right to fair
      : Based on the same reasoning that it was the
      banks w، decided to freeze the accounts but not the Police, the
      CFA further rejected that there was procedural unfairness by the
      issuance of LNCs. In any event, the appellants were open to (i)
      make representations with a view to dispelling the
      “, or to (ii) “seek relief a،nst the
      banks in a ‘suit at law’ for with،lding their
      “, or, as in what the appellants had done in this
      case, to (iii) resort to the courts in bringing judicial review
      proceedings a،nst the Police (§99 – 100). Hence, there
      was no procedural unfairness.


With the legality and cons،utionality of the LNCs regime being
affirmed, the key takeaways in our May 2023 legal update continue to apply.

Given the CFA has repeatedly emphasized that any
“freeze” is the bank’s own doing upon exercise of
independent judgment based on the terms and conditions provided
under the relevant banking contracts with their customers, banks
s،uld stay vigilant to any suspended frauds and s،uld exercise
their judgment carefully when being asked by an account ،lder to
،nour his/her instruction to pay out funds in such cir،stances,
whilst also balancing their legal and regulatory duties and their
،ential exposure to criminal liability.
