Proceedings and submissions Before her trial, Purwanti's murder charge was reduced to culpable homicide not amounting to murder, equivalent to manslaughter in Singapore's legal terms. The lesser offence did not carry a death sentence, but if convicted, Purwanti could either be
jailed for life, or up to ten years behind bars. Purwanti, who pleaded guilty to the reduced charge in September 2004, was represented by veteran criminal lawyer
Subhas Anandan and another attorney named Mohamed Nasser bin Mohamed Ismail, while Jaswant Singh led the prosecution.
Judicial Commissioner V K Rajah was the trial judge who presided the case. After the completion of the guilty plea and presenting the full statement of facts, the prosecution sought the maximum sentence of life imprisonment, on the grounds that the killing was "deliberate and calculated". The prosecution stated that the severity of the crime would have warranted Purwanti a conviction for murder, but she could not receive the death penalty for she killed Har while she was underaged, and the prosecution had no choice but to exercise its prerogative to reduce the charge against her. However, the prosecution stated this did not detract away the cold-blooded nature of the offence, since Purwanti clearly did not momentarily lose her self-control or sense of judgement when she strangled Har to death, and her anger against Har would have vanished by the time she stopped hesitating like her previous two attempts on Har's life and successfully killed Har on the third attempt, and her strangulation of Har was motivated by ill feeling, and her repeated attempts to kill Har were proof that she was in full control of her actions at the time of the killing. In response, Anandan argued that Purwanti should not be given a life sentence, as it was unduly harsh for Purwanti, who was a teenager barely above 18 and also a first offender in this case. Anandan also cited in mitigation that Purwanti had suffered relentless abuse from Har, and these series of mistreatment had gradually led to Purwanti unable to contain herself any longer, such that the scolding Purwanti received on the day of the killing became the final proverbial straw that broke the camel's back, causing Purwanti to finally snap and killed Har. Hence, Anandan urged the court to temper justice with mercy and be lenient with Purwanti on behalf of her young age, her lack of criminal records and the abuse she suffered from Har before the crime. Purwanti also made a written letter of apology to Har's family prior to her sentencing trial. Judicial Commissioner Rajah also stated that the killing cannot be justified or condoned under the pretext of Purwanti being a victim of maid abuse, and he noted that the principle of deterrence should be demonstratively upheld through the sentencing of Purwanti, in view of the increasing cases of maids committing crimes against their employers, the worst of them include murder. Therefore, Judicial Commissioner Rajah felt that as a unequivocal signal to any potential offenders among maids who wanted to retaliate against their violent and abusive employers through crime rather than seeking help from authorities, the sentence should be manifestly adequate in view of these rising cases, and to address the "disturbing case" of Purwanti killing Har, a crime which the judge described as "callous and heinous" with numerous aggravating factors that came into play. Therefore, Judicial Commissioner Rajah decided that the lower tier of up to ten years' imprisonment was "wholly inappropriate and inadequate" in Purwanti's case, and hence, he decided to, notwithstanding the defendant's relative youthfulness, sentence 19-year-old Purwanti Parji to life in prison, the maximum punishment warranted for manslaughter. The life term was also backdated to the date of Purwanti's arrest on 4 August 2003. With effect by the landmark ruling of
Abdul Nasir Amer Hamsah's appeal on 20 August 1997, life imprisonment in Singapore was to be construed as a sentence of incarceration for the rest of the prisoner's natural life, a departure from the old definition of life imprisonment as 20 years' jail, and the new definition would apply to future cases (specifically those punishable by life) after 20 August 1997. Since Purwanti committed the offence of manslaughter on 4 August 2003, nearly six years after the appeal verdict, Purwanti's life sentence meant that she was to spend the rest of her natural life behind bars. By coincidence, Abdul Nasir was a former client of Purwanti's lawyer Anandan, who twice defended Abdul Nasir during his trials for a Japanese tourist's murder and the abduction of a policeman for ransom. Har's bereaved family were present to hear the judgement. Michael Leong Kit Heng, the 58-year-old husband of Har, stated that the life sentence was a firm and fair one in spite of Purwanti having avoided the
death penalty, and he described her as a "dangerous person". Leong Meng Wei, Har's 33-year-old older son, called the murder of his mother "stupid" and refused to accept Purwanti's apology like the rest of his family members. Purwanti was the second maid to be given a life sentence for killing a member of her employer's household during that week itself. Four days before her, an Indonesian maid named
Sundarti Supriyanto was also sentenced to life in prison for killing her employer Angie Ng and Ng's three-year-old daughter Crystal Poh at Bukit Merah. Like Purwanti, Sundarti was convicted of manslaughter after the trial court found her not guilty of murder on the grounds that she was cruelly deprived of food and maliciously abused by Ng, which caused her to kill the two victims under sudden and grave provocation. ==Appeal of Purwanti==
