Although the legal system of Singapore is a common law system, the criminal law of Singapore is largely statutory in nature and historically derives largely from the former Indian penal code. The general principles of criminal law, as well as the elements and penalties of general criminal offences such as assault, criminal intimidation, mischief, grievous hurt, theft, extortion, sex crimes and cheating, are set out in the Singaporean Penal Code. Other serious offences are created by statutes such as the Arms Offences Act, Kidnapping Act, Misuse of Drugs Act and Vandalism Act.

Singapore retains both corporal punishment (in the form of caning) and capital punishment (by hanging) as legal penalties. For certain offences, the imposition of these penalties is mandatory. More than 400 people were executed in Singapore, mostly for drug trafficking, between 1991 and 2004. Statistically, Singapore has one of the highest execution rates in the world relative to its population. Science fiction writer William Gibson famously described Singapore as "Disneyland with the death penalty".. Some scholars have argued that one of the results of robust regulations and interventions in Singapore is that the nation has one of the lowest incidences of violent crimes in the world. .

History

The Penal Code For most of the 19th century, the criminal law which applied in the Straits Settlements (comprising the Prince of Wales' Island (Penang), Singapore and Malacca) was generally that of the United Kingdom. In 1871, the Straits Settlements Penal Code 1871, practically a re-enactment of the Indian Penal Code, was enacted.No. 4 of 1871 (S.S.). It came into operation on 16 September 1872. The code then held only two crimes punishable with the death penalty: murder and treason. Judges then had discretion on whether to impose the death sentence or instead sentence the convicted to life imprisonment. In 1883, the Penal Code (Amendment) Ordinance 1883 removed the discretion and imposed a mandatory death penalty on all convicted murderers. In 2012, the penal code was amended for judges to have some discretion in sentencing the death penalty in certain cases of murder.Recalibration of the Death Penalty Regime: Origin, Ramifications and Impact 35 Sing. L. Rev. 1 (2017)

The penal code has since been amended several times. In 1973, punishments for certain offences were enhanced. The Penal Code (Amendment) Act 1984, which came into effect on 31 August 1984, imposed mandatory minimum penalties for certain offences. A major review of the Code was launched in 2006, which was updated in 2008.

Criminal Procedure Code Prior to 1870, criminal procedure law in Singapore was found mainly in the Indian Criminal Procedure Act (ICPA) 1852,No. 16 of 1852 (Ind.). as the Indian government then had power to legislate for the Straits Settlements. After the passing of the Singaporean penal code, the ICPA was replaced by the Criminal Procedure Ordinance.No. 5 of 1870 (S.S.). Despite the penal code having done away with the division of crimes into felonies and misdemeanours, the criminal procedure system was still maintained the distinction, leading to the passing of the Criminal Procedure Ordinance 1873.No. 6 of 1873 (S.S.). The Ordinance also did away with the procedure for indictments and abolished the grand, special, and common juries.

A replacement Code of Criminal Procedure was enacted in 1902. The present Criminal Procedure CodeNow was passed by the Legislative Council of the Colony of Singapore on 28 January 1955. All criminal offences under the Penal Code or other statutes are inquired into and tried according to the Criminal Procedure Code, of which is last revision in 2010.

Misuse of Drugs Act In 1973, the Misuse of Drugs Act was passed, with a sentencing maximum of 30 years for drug-related offences. In 1975, the act was amended to impose a mandatory death penalty for select offences.

Sources of law Unlike the English criminal law, which contains both common-law and statutory crimes, the Singaporean criminal law comprises only crimes listed in statutes. The application of law is guided by case law as well as the Interpretation Act 1965, which requires courts to interpret statutes upon parliamentary intention.Interpretation Act 1965

Criminal justice system

Criminal justice model Former Chief Justice of Singapore Chan Sek Keong has described Singapore's criminal justice system as emphasising the control of crime over strict adherence to due process.

Punishment Both capital punishment and corporal punishment, in the form of caning, are legal in Singapore. Certain offences impose a mandatory death penalty on individuals, with judges having no discretion in sentencing. This differs from, for example, the United States, where mandatory death sentences are unconstitutional. Where judges have discretion in sentencing the death penalty for murder, the test is whether "the actions of the offender outraged the feelings of the community," considering the offender's viciousness, disregard for human life, age, and personal characteristics.

Aims of punishment The primary aim of criminal sentencing in Singapore is to punish and deter crimes.

Court process The Attorney-General of Singapore is also the public prosecutor.Article 35(8) of the Constitution of Singapores 11 of Criminal Procedure Code Deputy public prosecutors and Attorney-General Chambers staff act for the attorney-general. As the public prosecutor, the Attorney-General has prosecutorial discretion and may initiate, conduct or cease any criminal proceeding. The prosecution typically bears the burden of proof and is required to prove its case beyond a reasonable doubt.

In general, an accused person is usually first charged with a higher offence than what may be established on the facts of the case. The accused may plea guilty or claim trial at the first mention in the state courts. Defence counsel for the accused can also make written representations without prejudice legally to the prosecuting authority, whereupon the prosecution may consent to amend the charge with a lesser relevant offence, a process known as the plea bargain.

Testifying witnesses are not required to be given an oath or otherwise instructed to tell the truth. Instead, the Oaths and Declarations Act "gives the judge the prerogative whether to caution a witness ["to speak the truth"] or not."

Criminal jurisprudence

Actus reus Establishing actus reus in Singaporean criminal jurisprudence follows English precedent such as R v Miller and R v Instan. Actus reus must correspond with mens rea for an offence to be made out. A single mens rea may correspond with a series of separate acts that form part of the actus reus of an offence, such as when a person an accused stabs a victim and leaves him for dead but where the victim dies of exposure.Wang Wenfeng v PP 4 SLR 590

Abetment Three forms of abetment are recognised in Singapore law: instigation, conspiracy, and aiding. Instigation requires the support or encouragement of a crime.S Balakrishnan v PP 4 SLR 249 Where an individual intentionally does not interfere with another's offence, and such omission breaches a legal obligation, their omission may be regarded as abetment by aiding.

Where an individual forces another to commit a crime, and is the essential cause of the actus reus, then that individual does not merely abet the crime but can be regarded as committing the actus reus himself.Seah Lei Sie Linda v Public Prosecutor SGCA 26

Attempts Attempting to commit a crime, but failing to do so, is an offence.s 511 of the Penal Code 1871 The test for determining whether an act is a criminal attempt comprises two parts. First, the accused must have had the intention to commit a crime. Second, the accused must have acted in a way that furthers his intention to commit the crime.Han Fang Guan v Public Prosecutor SGCA 11

Common intention Section 34 of the Penal Code states that "when a criminal act is done by several persons, in furtherance of the common intention of all, each of such persons is liable for that act in the same manner as if the act were done by him alone."

When multiple persons each commit the same offending act, they are liable for that specific offence. In the case of Asogan Ramesh, three men attacked another man, resulting in the victim's death. Two assailants stabbed the deceased repeatedly, whilst the other man threw a chair over the deceased head, causing instant death. All three men were convicted of murder and sentenced to death.Asogan Ramesh s/o Ramachandren and others v Public Prosecutor 3 SLR(R) 201

When multiple persons commit a certain offence, and one such offender commits a collateral offence, all secondary offenders may be regarded as having committed the collateral offence, provided that they intended for the collateral offence to have occurred. In other words, so long as the secondary offenders have mens rea, they need not have committed an actus reus to be found guilty.The Final Twist in Common Intention? Daniel Vijay s/o Katherasan v. Public Prosecutor Sing JLS 237

If multiple individuals have a common intention in the committing of a crime, the mens rea element of all individuals can be made out.

Mens rea Generally, the prosecutor has the burden of proving, beyond a reasonable doubt, that an individual had mens rea.Yeo Ah Seng v PP 1 MLJ 231 The accused may rely upon a number of defences to prove an absence of mens rea. When a defence is relied upon, the factual burden shifts from the prosecutor to the accused to prove, on the balance of probabilities, the lack of mens rea.Nagaenthran a/l K Dharmalingam v PP 4 SLR 1156

For drug trafficking offences, individuals found in possession of a certain quantity of drugs are presumed to be guilty of the offence and having to prove, on the balance of probabilities, that they did not have mens rea. It is sufficient for an accused to prove that he merely did not know that the contents that he trafficked were controlled drugs. However, when the prosecution argues that an accused was wilfully blind, the burden remains on the prosecution.

The standard of criminal negligence is the same as that of civil negligence in Singapore law, including for professional negligence. Professionals who fail to meet the tortious Bolam standard can as criminally negligent as well.Lim Poh Eng v PP 2 SLR 116 The rule in Nettleship v Weston, that inexperience is not considered in negligence, has been affirmed in Singaporean criminal law.Ng Keng Yong v PP & Anor appeal 4 SLR 89 Notwithstanding, there is no proximate cause requirement in criminal negligence; the accused need only have substantially contributed to the harm incurred. Whereas negligence only requires individuals to fail to fulfil a duty of care, rashness additionally requires that an act be committed with the knowledge that it would fail, or risk failing, to meet that duty of care.Public Prosecutor v Poh Teck Huat SGHC 82

Wilful blindness is a way by which mens rea may be found in the absence of actual knowledge. It requires: a clear and grounded suspicion; reasonable means of inquiry of finding out; and a deliberate refusal to pursue such means.Gobi a/l Avedian v Public Prosecutor 1 SLR 180

Defences A number of general defences exist in Singaporean criminal jurisprudence, such as unsoundness of mind, automatism, and mistake. Unlike in some jurisdictions, the burden of proof of establishing defences lies upon the accused.Evidence Act (Cap. 97, 1997 Rev. Ed. Sing.), ss 103, 107
