Background

Soh Yuan-Yi, a former Credit Suisse relationship manager, pleaded guilty to 20 forgery charges and ten charges for dealing with benefits from criminal conduct. A further 123 charges were taken into consideration. Between 2006 and 2013, she forged at least 112 client instruction letters and carried out unauthorised transactions involving 22 accounts belonging to 15 clients.

Her conduct included transfers between client accounts, transfers through joint accounts under her control, payments for personal expenses, and transactions connected with the purported sale of her Amanusa property to a client without that client’s knowledge. She concealed the misconduct by, among other things, falsifying transaction reasons, recording false confirmations of client voice logs and callbacks, diverting correspondence, and altering bank documents.

A District Judge imposed 13 years’ imprisonment, with sentences for three forgery charges and two CDSA charges running consecutively. Soh appealed the sentences for the forgery charges and the aggregate sentence.

The Court’s Holding

The High Court allowed the appeal and reduced the global sentence to 10 years and 7 months’ imprisonment. It held that the District Judge had wrongly declined to account for the Amanusa property’s value when calculating Soh’s net benefit, and should not have given weight to Credit Suisse’s compensation figure because it included losses from uncharged trades and could not be apportioned to the charged conduct.

Most importantly, the District Judge had not properly followed the two-stage approach to sentencing multiple offences. Individual sentences must first be determined by charge-specific factors; cumulative features, including the scale and duration of the overall scheme, should then be considered when setting the aggregate sentence. The District Judge’s approach created a risk of double counting those cumulative factors.

Re-sentencing Soh, the court applied a 20% guilty-plea discount rather than 30%, given delay associated with an unsuccessful Newton hearing and a late change of counsel. It ordered three forgery sentences and one CDSA sentence to run consecutively. The CDSA sentences themselves remained undisturbed.

Key Takeaways

  • Multiple-offence sentencing requires a distinct charge-by-charge stage followed by an aggregate-sentence stage.
  • Cumulative aggravating factors should not be counted again when individual and consecutive sentences are set.
  • Loss or compensation figures that include uncharged conduct should not affect sentencing without a reliable basis for attribution.

Why It Matters

The decision reinforces that sentencing for complex financial crime must separate the gravity of each offence from the overall criminal enterprise. That structure promotes transparent sentencing and guards against excessive punishment through double counting.

It also confirms that a prosecutor that has not appealed a CDSA sentence should not effectively seek higher individual CDSA penalties on the offender’s appeal merely to preserve a global sentence.
