Understanding the Criminal Trial Process

From investigation to sentencing and appeal: a plain-English walk through how a criminal case moves through the Singapore courts, and who does what at each stage.

Updated October 2026 · About 11 min read

1. Overview

A criminal case asks one question: has the State proved that the accused person committed an offence? The answer comes from a process built around evidence, procedural safeguards and a decision by a court. In Singapore, the main rules are found in the Criminal Procedure Code 2010, the Evidence Act 1893, and the statute that creates the offence itself, such as the Penal Code 1871.

The exact steps depend on the offence, the court and the way the accused chooses to respond to the charge. This article follows the most common path and flags where cases branch off.

At a glance

  • No jury. In Singapore, a judge alone decides guilt in criminal trials.
  • The prosecution carries the burden. It generally has to prove its case beyond reasonable doubt.
  • Not every case goes to trial. Many are resolved when the accused pleads guilty, and some end with a warning or other outcome before any charge.
  • The process does not end at the verdict. Sentencing and appeals are separate stages with their own rules.

2. Key participants

Knowing who is in the room makes everything else easier to follow.

ParticipantRole
ProsecutionPresents the case for the State. Prosecutions are conducted under the authority of the Public Prosecutor, and Deputy Public Prosecutors from the Attorney-General’s Chambers appear in court.
AccusedThe person charged. The accused decides how to respond to the charge, with legal advice if they choose to have it.
Defence counselAdvises the accused, challenges the prosecution’s evidence and puts forward any defence.
JudgeManages the proceedings, rules on what evidence is admissible, decides guilt and imposes the sentence.
WitnessesGive evidence under oath or affirmation. They can include complainants, bystanders, investigating officers and experts.
Court interpretersAssist when a witness or accused person needs to give evidence in another language.

A complainant or victim is an important witness, but they are not the prosecutor. The decision to prosecute and the conduct of the case belong to the Public Prosecutor.

3. The journey at a glance

Here is a simplified sequence. Not every case follows every step, and the order can vary with the offence and the court.

  1. Report and investigationA report is made, and the police or another enforcement agency investigates. Evidence is gathered and statements may be recorded.
  2. Arrest and bailIf a person is arrested, they must generally be brought before a magistrate within 48 hours. For many offences, the court can grant bail or order the person to remain in custody.
  3. ChargeThe prosecution decides whether to charge and with what. The charge is formally read to the accused.
  4. PleaThe accused either pleads guilty or says they wish to claim trial.
  5. Pre-trial case managementThe court and parties fix dates, exchange information and deal with preliminary issues.
  6. TrialThe prosecution presents its evidence. If the court finds a case to answer, the defence responds.
  7. Verdict and sentencingThe judge acquits or convicts. After a conviction, the court hears submissions on sentence before imposing it.
  8. AppealEither side may be able to appeal in some circumstances, within strict time limits.

4. Before the courtroom: investigation, statements and bail

Investigation and arrest

Most cases begin with a police report, although other agencies such as the Central Narcotics Bureau and the Corrupt Practices Investigation Bureau investigate specific offences. Whether the police can arrest without a warrant depends on the offence. A person who is arrested and not released is generally to be produced before a magistrate within 48 hours.

Statements and why they matter

During an investigation, statements may be recorded from witnesses and from the suspect. After a person is charged, they may be given a notice that explains that they may say something in answer to the charge, and that keeping back a defence until trial can affect how the court views it later. Statements can become important evidence, so the law sets conditions for when a statement made by an accused person can be used. If its voluntariness is challenged, the court holds a separate hearing, often called an ancillary hearing, to decide whether the statement is admissible before the trial continues.

Access to a lawyer

An accused person may engage a lawyer, and arrested persons may ask to consult one, subject to the rules and to procedures that allow investigations to proceed. Legal aid may be available to eligible persons, including through schemes for those charged with capital offences and for other criminal matters.

Bail and remand

Bail is a promise, usually backed by a sum of money and a bailor, that the accused will attend court. Whether an offence is bailable, and whether bail is appropriate, depends on the offence and the circumstances. If bail is not granted, the person may be remanded.

Not every case reaches a trialThe prosecution may, in suitable cases, decide on an alternative such as a warning or composition (a payment that settles certain minor offences). Whether any of these are available depends on the offence and the circumstances.

5. The charge and the plea

The prosecution frames the charge, which tells the accused what they are alleged to have done and which law they are said to have broken. In court, the charge is read and explained. The accused’s response is the major fork in the road:

Plead guiltyClaim trial
What it meansThe accused admits the charge.The accused disputes the charge and puts the prosecution to proof.
What happens nextThe court checks the plea is voluntary and the accused understands it, then convicts and moves to sentencing.The case is prepared for trial.
Who decides the outcomeThe court still decides the sentence.The court decides guilt, and then sentence if there is a conviction.

Singapore courts speak of “claiming trial” rather than a “not guilty” plea. A guilty plea can be a significant mitigating factor in sentencing, but the court is not bound by any sentence the parties suggest. For more serious cases, a structured process exists in which the prosecution and the defence set out their positions before trial, so that the real issues are clear.

6. Inside the trial

Which court?

Most criminal cases are heard in the State Courts, in the Magistrates’ Courts or District Courts depending on the offence. The most serious cases, including capital offences, are tried in the High Court. A judge sits alone in these trials, and there is no jury.

The prosecution’s case

The prosecution calls its witnesses and presents documents and exhibits. Each witness goes through three stages: examination-in-chief (questions from the side calling them), cross-examination (questions from the other side, to test the evidence), and re-examination (a chance to clarify anything arising from cross-examination).

A case to answer

When the prosecution finishes, the judge decides whether it has presented enough evidence that, if unanswered, would justify a conviction. If not, the accused is acquitted without having to present a defence. If so, the accused is called to give their defence.

The defence’s case

The accused is told of the options, which include giving evidence on oath and calling other witnesses. The court may draw an adverse inference if the accused chooses not to give evidence without a good reason. The defence may also rely on specific legal defences set out in the law.

Closing submissions and decision

Both sides make closing arguments on what the evidence shows and what the law requires. The judge then decides whether the prosecution has proved each element of the charge. The standard is beyond reasonable doubt, which is a higher standard than the balance of probabilities used in civil cases. The judge then gives a verdict of guilty or not guilty and often explains the reasons in written grounds of decision, which you can learn to read in our guide on how to read a court judgment.

One thing to check for each offenceWhile the prosecution generally carries the burden of proof, some statutes contain presumptions that require an accused to rebut a particular fact once the prosecution proves other facts. The wording of the specific offence matters.

7. Sentencing and appeals

Sentencing

After a guilty plea or a conviction, the court hears from the prosecution and the defence on the appropriate sentence. The defence presents mitigation, which means personal circumstances and other factors that might reduce the sentence. The court may also call for reports on the offender. Depending on the offence, the court may consider imprisonment, fines, caning for certain offences, probation, community-based sentences, or treatment-oriented orders. The law provides different options depending on the offence and the offender’s age and circumstances, and some offences carry minimum or mandatory penalties. Singapore courts follow sentencing principles including deterrence, retribution, prevention and rehabilitation, giving different weight to each depending on the case.

Appeals

An accused person who is convicted can generally appeal against the conviction, the sentence, or both. In some situations, the Public Prosecutor may also appeal against an acquittal or a sentence. Appeals from the State Courts go to the High Court, and appeals from High Court trials go to the Court of Appeal. Time limits are short and strict, generally measured in days from the decision, so anyone considering an appeal should seek legal advice immediately. There are also limited mechanisms to refer questions of law, or to seek a review of a decided case, but these are exceptional.

8. Common misconceptions

Select a statement to see how the process actually works.

“The accused has to prove their innocence.”

Generally, no. The prosecution has to prove the charge beyond reasonable doubt. However, certain statutes include presumptions that can shift a burden onto the accused for specific facts, so it is important to check the offence in question.

“A jury decides the verdict.”

Not in Singapore. Criminal trials are conducted by a judge, who decides both the facts and the law.

“Staying silent can never count against you.”

It is more complicated than that. The accused is not forced to testify, but the law allows a court to draw an adverse inference in certain situations, such as when a defence is withheld until trial or when an accused chooses not to give evidence without good reason.

“Once someone pleads guilty, that is the end of it.”

The court still has to be satisfied that the plea is voluntary and that the accused understands it. The court also decides the sentence for itself after hearing both sides.

“An acquittal is always final.”

Not always. In some circumstances, the prosecution can appeal against an acquittal, and the appellate court will decide whether the decision should be upheld.

9. Why procedure matters

Procedure is more than paperwork. Rules on disclosure, admissibility of evidence and the right to be heard help ensure a hearing is fair and that decisions can be reviewed on appeal. They also protect the interests of victims and the public by making sure evidence is tested before conclusions are drawn. Because the rules change from time to time, always check the current legislation for rights, deadlines and applications.
