Magistrate's Complaint in Singapore

The Magistrate's Complaint procedure is set out in section 152 of the Criminal Procedure Code 2010 (CPC). The procedure allows any person to make a complaint to a Magistrate alleging that an offence has been committed.

The procedure exists because Singapore criminal prosecutions are normally commenced by the Public Prosecutor on the basis of police investigation. The Magistrate's Complaint provides a route for matters that have not engaged police attention — typically because the police have declined to investigate, the complainant prefers not to involve the police, or the matter is at a stage where alternative resolution is preferred.

Who may file

Any person may file a Magistrate's Complaint. The complainant must have personal knowledge of the matter complained of; hearsay-only complaints are typically rejected at the threshold. The complaint may relate to an offence committed against the complainant, against a family member, or against the public interest where the complainant has direct knowledge.

What may be complained of

The procedure is most commonly used for offences in the following categories:

• Voluntarily causing hurt under section 321 of the Penal Code 1871 and adjacent provisions.
• Criminal intimidation under section 506 of the Penal Code 1871.
• Mischief — damage to property — under section 425 onwards of the Penal Code 1871.
• Defamation under section 499 onwards of the Penal Code 1871.
• Outrage of modesty under section 354 of the Penal Code 1871 (though most such matters are pursued through police investigation).
• Other less-serious interpersonal offences.

Serious indictable offences — drug trafficking, sexual offences against children, robbery, capital matters — are not appropriate for the Magistrate's Complaint procedure. Such matters are investigated by the police and prosecuted by the Attorney-General's Chambers as a matter of routine. For the broader procedural framework, see our hub explainer on criminal defence in Singapore.

The procedure runs through the Crime Registry of the State Courts.

Step 1: prepare the complaint

The complaint is set out in writing, in narrative form, identifying:

• The complainant's name and identification.
• The respondent's name and identification (or, where unknown, sufficient details to identify the person).
• The facts complained of — what happened, when, where, and who was involved.
• The offence the complainant says was committed.
• Supporting documents, photographs, medical reports, witness particulars, and any prior police reports.

Many complainants engage a Singapore-qualified lawyer to prepare the complaint, particularly where the factual narrative is contested or where the legal characterisation of the conduct as a defined offence requires care. Self-represented complaints are common but the Magistrate is more likely to act decisively where the complaint is professionally drafted.

Step 2: file at the Crime Registry

The complaint is filed at the Crime Registry of the State Courts. The filing fee is modest and is set out in the State Courts' published fee schedule. The complainant attends in person to swear or affirm the complaint.

Step 3: examination by the Magistrate

Under section 153 of the CPC, the Magistrate examines the complainant on oath. The examination is intended to satisfy the Magistrate that the complaint discloses an offence and that there is a reasonable basis for inquiry. Hearsay-only allegations, manifestly trivial matters, and abusive or vexatious complaints are typically dismissed at this stage.

Step 4: directions

If satisfied, the Magistrate may:

• Direct the matter to court mediation at the Community Justice Centre or the Community Mediation Centre, particularly for interpersonal disputes where reconciliation is possible.
• Refer the matter for police investigation, requiring the police to investigate and report.
• Issue a summons to the respondent to appear in court for further inquiry or charge.
• Dismiss the complaint where no offence is disclosed or no basis for further inquiry exists.

Step 5: response by the respondent

Where summons or referral is ordered, the respondent is notified and required to attend court or respond to police investigation. The respondent is entitled to legal representation throughout.

For many interpersonal matters — workplace disputes, neighbour disputes, family disputes — the Magistrate directs the parties to mediation before the matter proceeds further. The mediation step is a critical feature of the Magistrate's Complaint procedure, and resolves a high proportion of cases without further court involvement.

Where mediation happens

Mediation typically occurs at:

• The Community Justice and Tribunals Division of the State Courts.
• The Community Mediation Centre, administered by the Ministry of Law.
• In some matters, family-specific mediation services.

How mediation works

The mediator is a trained professional who facilitates discussion between the parties. The aim is to reach an agreed resolution — typically an apology, an undertaking to avoid future conflict, a payment for damages or medical costs, or a structured arrangement for ongoing interactions (for example, between neighbours sharing a corridor or workplace colleagues). The mediator does not adjudicate; the outcome is what the parties agree.

Settlement and discontinuance

Where mediation reaches a settlement, the complainant typically applies to discontinue the Magistrate's Complaint. The Magistrate considers the application. For complaints that may be compounded — that is, where the law permits the complainant to settle the matter — discontinuance is straightforward. For non-compoundable offences (some forms of voluntarily causing hurt, some forms of outrage of modesty), the matter cannot be discontinued by the complainant alone, and the Magistrate considers whether the public interest requires further proceedings.

Where mediation fails

If mediation does not produce a settlement, the matter returns to the Magistrate. The Magistrate may then refer the matter for police investigation, issue a summons, or, in some cases, dismiss the complaint where it is clear that the public interest would not be served by further proceedings.

A significant proportion of Magistrate's Complaints resolve at the mediation stage. Going into mediation prepared — with a clear narrative of grievance, a realistic outcome in mind, and the support of professional advice where the dispute is complex — materially increases the chance of a productive resolution.

Where mediation does not resolve the matter, or where the offence is too serious for mediation, the matter proceeds along one of two tracks.

Police investigation

The Magistrate may refer the matter to the Singapore Police Force under section 159 of the CPC. The police are required to investigate and report back to the court. Investigation involves:

• Interviews with the complainant, respondent, and witnesses.
• Statements under section 22 of the CPC.
• Collection of physical evidence — medical reports, CCTV footage, message logs, photographs.
• Forensic evidence where applicable.

On completion, the investigation report is submitted to the Attorney-General's Chambers, which decides whether to commence prosecution. Where prosecution is commenced, the matter then proceeds as a routine criminal case through the State Courts.

Summons

For some matters, the Magistrate may issue a summons directly under section 154 of the CPC, requiring the respondent to appear before the court for further inquiry. The respondent attends; the matter is then dealt with in court, with the complainant and respondent both able to give evidence.

Decision to prosecute

Even where police investigation produces evidence of an offence, the Attorney-General's Chambers retains the discretion not to prosecute. The decision is based on the public interest, the seriousness of the matter, the strength of the evidence, and the circumstances of the parties. The Magistrate cannot direct the Attorney-General's Chambers to prosecute; the constitutional separation of prosecutorial discretion under Article 35(8) of the Constitution of the Republic of Singapore is final.

Outcomes if prosecution follows

Where prosecution follows, the matter is handled as a routine criminal case. The respondent becomes the accused, with all the rights of an accused person — to remain silent on the substance of the offence, to legal representation, to challenge the prosecution evidence, and to a fair trial. Sentence on conviction follows the normal sentencing framework for the offence in question.

Costs

The court may, in defined circumstances, order costs against an unsuccessful complainant where the complaint was frivolous, vexatious, or made without reasonable grounds. The threshold is high, but the possibility is a real consideration for complainants whose case is weak.

The Magistrate's Complaint procedure has clear strengths and meaningful limits. Understanding both helps prospective complainants and respondents make informed decisions.

Strengths of the procedure

• Accessible — the filing fee is modest, no lawyer is strictly required, and the Crime Registry handles many self-represented complainants.
• Mediation-friendly — the structured mediation step resolves a substantial proportion of cases without escalation.
• Triggers official involvement — for matters the police would otherwise not investigate, the Magistrate's referral compels official inquiry.
• Permits private remedies — for interpersonal disputes where the complainant wants acknowledgment and a structured resolution rather than punishment, the procedure delivers.

Limits of the procedure

• Cannot direct prosecution — the Attorney-General's Chambers retains the final word. A complainant cannot compel prosecution of a respondent.
• Vexatious complaints carry risk — the court may order costs against complainants whose cases were frivolous or vexatious.
• Limited remedy for serious offences — the procedure is not the right vehicle for capital matters, serious sexual offences, or organised crime; these proceed through routine police investigation.
• Time and emotional cost — even successful complaints take time, with multiple court attendances over weeks or months.
• Risk of counter-complaint — the respondent may file a counter-complaint, particularly in interpersonal disputes where the parties' accounts diverge.

When to engage a lawyer

For straightforward, low-value, interpersonal disputes — neighbour disputes, minor workplace altercations, minor mischief — self-representation through the procedure is feasible. For more complex matters, professional engagement adds value: the lawyer drafts the complaint to maximise its prospects of acceptance, advises on the mediation strategy, prepares evidence for any subsequent proceedings, and manages the relationship with the police and the prosecution where the matter escalates.

Respondents to a Magistrate's Complaint should engage a Singapore-qualified lawyer at the earliest possible point — ideally before responding substantively to the complaint or to any police investigation. Statements made informally to the complainant or to investigators can be deployed in subsequent proceedings. You may begin at our find a lawyer directory or contact us page.
