Ng's lawyer applies to impeach Cecilia Sue
SINGAPORE: Significant discrepancies continued to plague the corruption trial of former chief of Central Narcotics Bureau (CNB), Ng Boon Gay.
This led to the defence asking for Ms Cecilia Sue Siew Nang's testimony to be impeached and the prosecution questioning Ms Sue as a hostile witness.
Forty-six-year-old Ng is accused of obtaining oral sex from Ms Sue.
In exchange, he allegedly furthered the business interests of her then employers - Hitachi Data Systems and Oracle Singapore.
Earlier in the day, the defence sought to impeach Ms Sue's evidence.
Senior Counsel Tan Chee Meng, who represents Ng, told the court at the start of the hearing that he sought to admit various statements made by Ms Sue.
To clarify his intent and purpose, he made the impeachment application again on Monday morning.
Senior Counsel Tan went on to point out several inconsistencies in Ms Sue's testimony.
One area was how she got to know of CNB's budget of S$320,000 for an IT contract awarded in 2011.
Ms Sue had previously told CPIB that the exact budget was provided by a Mr Paul Chew.
But she later told the court that Ng was the one who told her over the phone that the budget ranged at "a few hundred thousand dollars".
An issue was raised whether Ng had influence over the awarding of government contracts.
Referring to Ms Sue's statement to the CPIB, the defence said Ng had no influence.
But when asked again in court, Ms Sue said she wouldn't know if he really influenced the process.
This prompted Senior Counsel Tan to accuse Ms Sue of "fabricating answers" as she went along.
Ms Sue rebutted, saying the senior counsel was "damaging" her reputation.
When asked by defence why she was lying, Ms Sue said: "I'm not lying. I can't speak his mind. Sometimes they don't follow what they say."
She maintained her oral evidence is the truth.
The defence is building a case where Ms Sue had an affair with Ng from as early as 2009.
But Ms Sue denied this in court and the defence sought to impeach her credibility.
With impeachment, the judge will have to decide at the close of trial, which version of the evidence is to be taken.
In a surprise turn of events, Deputy Public Prosecutor Tan Ken Hwee applied to cross-examine key prosecution witness, Ms Sue.
He also requested to admit five statements given to the Corrupt Practices Investigation Bureau (CPIB) investigators.
The move follows contrasting evidence given by Ms Sue during investigations and on the stand.
Ms Sue had earlier told CPIB that she and Ng were in a sexual relationship.
But on the stand, she denied this.
The numerous inconsistencies prompted the prosecution to question her as a hostile witness.
Ms Sue disagreed when DPP Tan said she had a "consensual relationship with the accused from 2009 to September or October 2010".
DPP Tan added: "I put it to you that you still depended on him for advice."
Ms Sue agreed.
The prosecution added that the main reason Ms Sue was "reticent" was due to concern for her family.
She again disagreed.
In her defence, Ms Sue maintained that her oral evidence in court is the truth and that previous statements were not.
Lawyers Channel NewsAsia spoke to said a witness' credibility is attacked when he or she is impeached.
They said this happens when a witness makes contradictory statements.
Mr Louis Joseph, a lawyer with L.F. Violet Netto, said impeachment is usually carried out by the prosecution and "fairly rare" by a defence counsel.
As for a hostile prosecution witness, lawyers said it is someone who deviates from prior police statements and gives evidence favouring the accused person.
Mr Amolat Singh, a lawyer at Amolat & Partners, said: "When your own witness turns hostile, which means that he starts to give evidence that is unfavourable to you or that goes against what your case is all about, then you can apply to the court to cross-examine your own witness. It is not something that is unusual, it happens from time to time."
Mr Joseph added that a hostile witness may also be prosecuted for giving a false statement to the police under Section 182 of the Penal Code and perjury to the Court.
The prosecution is expected to wrap up its questioning of Ms Sue on Tuesday.
A third witness - CNB's Deputy Director Marvin Sim - is expected to testify on October 2.
