Getting a call from the police, or worse, being arrested, can turn your world upside down in seconds. Suddenly you are thrown into the Singapore criminal justice system, a process governed by strict timelines, formal procedures, and legal terms that rarely make sense to someone going through it for the first time.
This is true whether you are an individual facing investigation, a worried family member trying to support a loved one, or a business owner whose company has come under regulatory scrutiny. Not knowing what happens next, or how long each stage takes, only adds to the stress.
This guide breaks down the criminal justice process Singapore courts and law enforcement follow, from the moment of arrest through to sentencing and appeal. By the end, you will understand each stage clearly enough to know what to expect, and why getting legal advice early can change the outcome of a case.
What Is the Singapore Criminal Justice System
The Singapore criminal justice system operates on an adversarial basis. The prosecution and the defence each present their case before a judge, who then decides on guilt and, where applicable, the sentence.
Two principles run through every stage of this system. The first is the supremacy of law, meaning every person, regardless of background or status, is accountable to the same legal standards. The second is the protection of public interest, which ensures the law serves the wider community rather than any single party.
An accused person is presumed innocent until proven guilty. The burden of proving guilt beyond reasonable doubt sits entirely with the prosecution, not the accused. This single principle shapes how the entire criminal justice process Singapore applies, from the first police report all the way to a final verdict.
If you are currently facing an investigation, our criminal law practice can walk you through what this means for your specific case.
Stage 1: The Arrest Procedure Singapore Police Follow
Most cases begin with a police report or information reaching law enforcement that suggests an offence has taken place. From there, the arrest procedure Singapore authorities use depends on how the offence is classified.
Arrestable Offences
These are offences that generally carry a maximum punishment of at least two years’ imprisonment. Examples include theft, rape, robbery, voluntarily causing grievous hurt, and offences under the Misuse of Drugs Act.
For arrestable offences, the police can arrest a suspect without a warrant, provided they have credible information and reasonable grounds for suspicion.
Non-Arrestable Offences
These typically carry a fine of $5,000 or less, imprisonment of up to six months, or both. For these matters, the police generally need a warrant before making an arrest, and will often issue a summons requiring the person to appear before a Magistrate instead.
What Happens During Remand
Once arrested, a suspect can be held in police custody for up to 48 hours without being formally charged. This period is known as remand. During this time:
- Investigators may question the suspect and gather evidence
- The police may apply for an extended remand order if more time is needed
- The suspect must cooperate with the investigation but retains the right against self-incrimination
- Access to a lawyer may be delayed if it would interfere with ongoing investigations
At the end of the 48-hour window, the police must either release the suspect or move forward with charging.
If you have been called up for questioning or arrested, speaking to a lawyer before your police interview matters more than most people realise. Our team regularly advises clients at this exact stage, and you can read how we have helped others in similar situations on our criminal matter testimonials page.
Stage 2: Investigation and the Decision to Charge
After arrest or the issuance of a summons, investigators continue building their case. This usually involves interviewing witnesses, reviewing CCTV footage, collecting forensic evidence, and compiling statements.
The findings are then passed to the Attorney-General’s Chambers, which in Singapore also acts as the Public Prosecutor. The Public Prosecutor holds prosecutorial discretion under the Singapore Constitution, meaning the decision on whether to charge a person, and with what offence, cannot be reviewed by the courts.
If the evidence is sufficient, formal charges are filed, and the accused is given a court date.
Stage 3: First Court Appearance at the Criminal Mentions Court
The accused must be brought before the State Courts within 48 hours of arrest, typically at the Criminal Mentions Court. The charge is read out and explained in a language the accused understands.
At this hearing, the accused has two options:
- Plead guilty – the matter can proceed to a mitigation plea and sentencing, sometimes within the same hearing
- Claim trial – any response short of an unequivocal guilty plea is treated as an intention to contest the charge
The court also decides at this point whether the accused will be granted bail or remain in custody, based on the severity of the offence and flight risk.
Stage 4: Pre-Trial Proceedings
Before a trial begins, both sides prepare their case. This stage generally includes:
- Pre-Trial Conferences (PTCs) – the court sets deadlines for filing the Case for the Prosecution and the Case for the Defence, and the judge may narrow down the actual issues in dispute
- Criminal Case Disclosure Conferences (CCDC) – both sides exchange evidence ahead of the hearing, which can streamline the case or, in some instances, lead to resolution without a full trial
- Bail hearings – conditions for release pending trial are reviewed and set
Once preparation is complete, the judge sets a trial date.
Stage 5: The Trial
Singapore does not use a jury system for criminal trials. A judge alone hears the evidence and delivers the verdict.
During the trial, the prosecution presents its case first, calling witnesses and submitting evidence to support the charge. The defence then cross-examines these witnesses and presents its own case in response. Both sides close with final arguments summarising their position.
This is the stage where preparation matters most. How well evidence is challenged, how credible a witness appears under cross-examination, and how clearly a defence is argued can shape the entire outcome.
Stage 6: The Verdict and Sentencing
If the prosecution proves its case beyond reasonable doubt, the judge delivers a guilty verdict. The case then moves directly into a mitigation plea, where the defence presents reasons for a lighter sentence, such as the accused’s personal circumstances, lack of prior record, or genuine remorse.
The court weighs both mitigating and aggravating factors before deciding on the final sentence. Sentencing in Singapore is fact-sensitive, and the courts apply the law equally regardless of a person’s social status or academic qualifications.
If the prosecution fails to prove its case, the accused is acquitted, and the matter concludes there.
Stage 7: Appeals
A case does not always end at sentencing. Either the prosecution or the defence may appeal to a higher court if they believe the judgment contains an error in law or fact, or that the sentence is manifestly excessive or manifestly inadequate.
Appeals must be filed within a strict timeframe, so speaking to a lawyer immediately after a verdict is critical if you intend to challenge the outcome.
Why Early Legal Representation Changes the Outcome
The criminal justice process Singapore enforces moves quickly, often within hours and days rather than weeks. Decisions made early, such as what is said during a police interview, whether to apply for bail, and how a charge is initially responded to, can shape the entire direction of a case.
This applies equally to individuals facing personal charges and to companies under investigation for commercial or regulatory offences. Businesses should be particularly aware that companies and their directors can face criminal liability separate from civil exposure, often requiring both to be managed at the same time. If your matter involves a company or its directors, our business law practice can advise on how criminal and civil exposure may intersect.
Family members supporting a loved one through this process often have legal questions of their own, particularly where a criminal matter overlaps with family law and divorce proceedings.

Frequently Asked Questions
How long can the police hold someone before charging them in Singapore?
The police can generally hold a suspect for up to 48 hours without a warrant before either charging them or releasing them. If more time is needed for investigation, the police can apply to the court for an extended remand order.
What is the difference between an arrestable and non-arrestable offence?
Arrestable offences carry a maximum punishment of at least two years’ imprisonment, and police can arrest a suspect without a warrant. Non-arrestable offences carry lighter penalties, generally a fine of $5,000 or less or up to six months’ imprisonment, and typically require a warrant or summons rather than an immediate arrest.
Do I have the right to a lawyer during police questioning?
Yes, but access may be delayed if it would interfere with the investigation. You also have the right against self-incrimination, meaning you do not have to say anything that may expose you to a criminal charge, though you must not lie to investigators.
What happens if I plead guilty at my first court hearing?
If you plead guilty, the matter can move directly to a mitigation plea, where you present reasons for a lighter sentence. In some cases, this and the final sentencing can happen within the same hearing.
Can a criminal court decision be appealed in Singapore?
Yes. Either the prosecution or the defence can appeal to a higher court if they believe the judgment contains an error in law or fact, or that the sentence is manifestly excessive or inadequate. Appeals must be filed within a strict statutory timeframe.
