Summary

In Abdul Ghufran bin Abdul Wahid v Public Prosecutor [2025] SGHC 98, a three-judge panel of the General Division of the High Court delivered a landmark judgment clarifying the judicial approach to determining the "notional imprisonment period" (NIP) under the fitness to plead regime. The case arose from a criminal revision application filed by the applicant, a 30-year-old man with a moderate intellectual disability, who had been found incapable of making his defence in respect of several charges involving voluntarily causing hurt and outrage of modesty. The central controversy concerned the District Judge’s determination of a nine-month NIP, which the applicant contended should have been significantly shorter, specifically one and a half months.

The High Court’s decision is significant for its comprehensive exposition of the fitness to plead regime under Part 13, Division 5 of the Criminal Procedure Code 2010 (2020 Rev Ed) ("CPC"). The court emphasized that the determination of the NIP is a distinct exercise from sentencing. Unlike sentencing, which is inherently punitive and follows a conviction, the NIP is a facilitative mechanism designed to set a "limiting term" for the Minister’s discretion in ordering the confinement of an accused person who has not been—and may never be—convicted of the alleged offences. The judgment establishes that the primary consideration in determining the NIP is prevention, specifically the protection of the public from potential harm, rather than retribution or deterrence.

The court further clarified the relevance of an accused person’s mental condition in the NIP determination. While a mental condition is a standard mitigating factor in sentencing, its role in the NIP context is more complex. The court held that unless the mental condition has a clear material bearing on the length of the notional sentence (for instance, by significantly reducing the accused’s culpability in a way that would have resulted in a shorter sentence upon conviction), it should generally be excluded from the NIP calculation. This prevents the court from inadvertently engaging in a full sentencing exercise for a person who remains legally innocent.

Ultimately, the High Court dismissed the application for criminal revision, finding that the District Judge had not committed any error of law or principle that resulted in a serious injustice. The nine-month NIP was upheld as a reasonable estimation of the sentence the applicant would have received had he been convicted, particularly given his history of similar offending and the moderate-to-high risk of recidivism identified by psychiatric experts. The judgment provides a robust framework for lower courts to follow, ensuring consistency and clarity in a sensitive area of criminal procedure where the liberty of mentally vulnerable individuals intersects with the state's duty to ensure public safety.

Timeline of Events

1. 1 December 2024: The applicant committed the first set of offences, involving biting a victim and committing acts of outraging and insulting modesty.
2. 25 December 2024: The applicant committed a second set of offences, including forcefully hugging a third victim and voluntarily causing hurt.
3. 28 December 2024: The applicant was officially charged in the State Courts.
4. 6 January 2025: Dr Soh Keng Chuan, a consultant psychiatrist with the Institute of Mental Health (IMH), issued the IMH Report regarding the applicant’s mental state and fitness to plead.
5. 27 January 2025: Based on the IMH Report and the testimony of Dr Soh, the court found the applicant was incapable of making his defence. The proceedings were stayed, and the court proceeded to consider whether to order a conditional release or report the case to the Minister.
6. 11 February 2025: The District Judge declined to order the applicant’s conditional release, opting instead to report the case to the Minister for Home Affairs.

8. 4 March 2025: Suzana Binte Masaid, the applicant's sister, filed an affidavit in support of the applicant's position regarding his care and supervision.
9. 17 April 2025: The High Court heard the application for criminal revision (Criminal Revision No 1 of 2025).
10. 27 May 2025: The High Court delivered its judgment, dismissing the application for criminal revision and upholding the nine-month NIP.

What Were the Facts of This Case?

The applicant, Abdul Ghufran bin Abdul Wahid, was a 30-year-old man who faced six charges in the State Courts. These charges comprised three counts of voluntarily causing hurt under s 323 of the Penal Code 1871, two counts of outraging modesty under s 354(1) of the Penal Code 1871, and one count of insulting modesty under s 377BA of the Penal Code 1871. The offences occurred across two dates in December 2024. On 1 December 2024, the applicant bit the first victim, exposed his genitals to her, and insulted her modesty. On 25 December 2024, he forcefully hugged a third victim and bit a fourth victim. The victims were generally elderly male strangers, often in wheelchairs, whom the applicant targeted in an unprovoked manner.

The applicant had a significant history of prior convictions for similar conduct, including an outrage of modesty conviction in 2012 and voluntarily causing hurt convictions in 2015 and 2021. Following his arrest for the 2024 offences, he was remanded at the Institute of Mental Health for psychiatric assessment. Dr Soh Keng Chuan, a court-appointed consultant psychiatrist, diagnosed the applicant with a moderate intellectual disability. Dr Soh’s report, dated 6 January 2025, concluded that while the applicant was not of unsound mind at the time of the offences (meaning he understood the nature and wrongfulness of his acts), he was currently "incapable of making his defence." This incapacity stemmed from his inability to understand the court proceedings, instruct his counsel effectively, or follow the evidence presented against him.

Crucially, Dr Soh opined that the applicant’s intellectual disability "diminished his ability to appreciate the wrongfulness of his conduct and reduced his capacity to exercise self-control and restraint" (at [5]). Furthermore, the risk of recidivism was assessed as "moderate to high," particularly given the unprovoked nature of his attacks on vulnerable individuals. Dr Soh recommended that the applicant required "close and constant supervision" to prevent further offending, as his family’s previous attempts to manage his behavior had proven insufficient.

In the State Courts, the District Judge (DJ) accepted Dr Soh’s findings. Under s 248(1) of the Criminal Procedure Code 2010, the DJ found the applicant unfit to plead and stayed the proceedings. The DJ then had to decide between ordering a conditional release under s 249(1) or reporting the case to the Minister under s 249(2). Despite the applicant’s sister, Suzana Binte Masaid, providing an affidavit promising to supervise him, the DJ found that the proposed supervision plan was inadequate to mitigate the risk the applicant posed to the public. Consequently, the DJ reported the case to the Minister.

As part of this reporting process, s 249(10) of the CPC required the DJ to determine a "notional imprisonment period." This NIP represents the term of imprisonment the court would have likely imposed if the accused had been convicted of the offences. The DJ calculated the NIP by looking at the individual charges: four months each for the two most serious charges (voluntarily causing hurt and outrage of modesty) and one month for the insult of modesty charge. By ordering two of the four-month terms and the one-month term to run consecutively, the DJ arrived at a total NIP of nine months. The applicant challenged this determination via criminal revision, arguing that the DJ failed to properly account for his mental disability as a mitigating factor and that the resulting NIP was "manifestly excessive."

What Were the Key Legal Issues?

The High Court identified several critical legal issues arising from the interpretation of the fitness to plead regime, which was substantially amended by the Criminal Justice Reform Act 2018. The primary issues were:

• The Nature of the NIP: What is the precise legal nature of the "notional imprisonment period" under s 249(10) of the Criminal Procedure Code 2010, and how does the court’s role in determining it differ from its role in a standard sentencing exercise?
• Evidentiary Requirements: Is the Prosecution required to adduce evidence to establish the physical elements (actus reus) of the offence before the court can determine the NIP, given that the accused has not been convicted?
• Relevance of Prevention and Rehabilitation: To what extent should the statutory sentencing objectives of prevention and rehabilitation influence the determination of the NIP?
• Relevance of Mental Condition: Should the court consider the accused person’s mental condition—which is the very reason for the stay of proceedings—as a mitigating or aggravating factor when calculating the NIP?
• The Procedural Framework: What is the correct step-by-step framework that a court should apply when determining the NIP under s 249(10) of the CPC?

These issues required the court to balance the protection of the public with the fundamental principle that a person should not be punished for a crime they have not been proven to have committed. The court noted that the fitness to plead regime is intended to be "facilitative" rather than "punitive," as stated by Ms Indranee Rajah during the Parliamentary debates on the Criminal Justice Reform Act 2018.

How Did the Court Analyse the Issues?

The High Court began its analysis by providing an overview of the four-stage fitness to plead regime under the Criminal Procedure Code 2010. This context was essential to understanding where the NIP fits into the broader statutory scheme.

The Four-Stage Regime

Stage 1: Investigation. Under s 247(1) of the CPC, if the court has reason to believe the accused is "incapable of making his defence," it must investigate the matter, typically by calling for a psychiatric report and examining the medical practitioner.

Stage 2: Finding of Incapacity. If the court finds the accused is indeed incapable, it must stay the proceedings under s 248(1). This is not an acquittal; the charges remain live but dormant.

Stage 3: Court’s Orders. Under s 249, the court must then decide whether to (a) release the accused on a "discharge order" with conditions (s 249(1)), or (b) report the case to the Minister (s 249(2)). If the court reports to the Minister, it must determine the NIP under s 249(10).

Stage 4: Minister’s Orders. The Minister, upon receiving the report, may order the accused’s confinement in a psychiatric institution or other safe place. Crucially, s 249(21) provides that the Minister cannot order confinement for a period exceeding the NIP determined by the court.

The Nature of the NIP vs. Sentencing

The court held that the determination of the NIP is not a sentencing exercise. Sentencing follows a conviction and is intended to punish the offender. In contrast, the NIP applies to an accused person who has not been convicted. The court observed at [45]:

"When a court sentences an offender, it is dealing with a person who has been convicted of an offence... Conversely, when determining the NIP, the court is dealing with an accused person who has not been convicted of any offence."

The NIP serves as a "limiting term" or a "ceiling" on the Minister’s power of confinement. Its purpose is to ensure that an unconvicted person is not confined for longer than they would have been imprisoned had they been convicted and sentenced. The court's role is "facilitative," providing the Minister with the necessary judicial parameters to exercise executive discretion.

Evidentiary Requirements

The court rejected the suggestion that the Prosecution must prove the physical elements of the offence beyond a reasonable doubt before an NIP can be set. Because the proceedings are stayed at Stage 2, a trial on the merits is impossible. Instead, the court should rely on the "undisputed facts" or the "case for the prosecution" as presented in the charges and supporting documents. If the accused (through counsel) disputes the underlying facts of the conduct, the court must make a "notional" assessment based on the available material, without conducting a mini-trial.

The Primary Consideration: Prevention

In a significant doctrinal development, the court held that prevention is the primary consideration in determining the NIP. While sentencing involves a balance of retribution, deterrence, prevention, and rehabilitation, the NIP context is different. Retribution and deterrence are punitive concepts that presuppose a conviction and moral blameworthiness. Since the accused is not convicted, these factors are less relevant. However, the state has a legitimate interest in preventing harm to the public. The court stated at [53]:

"In our judgment, the primary consideration in determining the NIP should be that of prevention."

This means the NIP should reflect the term of imprisonment that would have been necessary to protect the public from the accused, had they been convicted.

The Relevance of the Accused’s Mental Condition

The court addressed the "paradox" of the accused’s mental condition. In sentencing, a mental condition often mitigates a sentence by reducing culpability (as seen in Lim Ghim Peow v Public Prosecutor [2014] 4 SLR 1287). However, the same condition might increase the need for prevention if it makes the offender more dangerous (as discussed in Public Prosecutor v Aniza bte Essa [2009] 3 SLR(R) 327).

The High Court concluded that, generally, the accused’s mental condition should be ignored when determining the NIP, unless it would have had a "material bearing" on the sentence upon conviction. The court reasoned that since the NIP is a "notional" sentence, the court should first determine the "benchmark" sentence for the conduct itself. If the mental condition is so severe that it would have significantly reduced the sentence (e.g., through a finding of diminished responsibility), then it should be considered. Otherwise, the focus remains on the gravity of the acts committed.

The Framework for Determining the NIP

The court established a three-step framework for determining the NIP:

1. Step 1: Determine the individual notional imprisonment terms for each charge. The court should look at the nature of the acts, the harm caused, and the "benchmark" sentences for such offences.
2. Step 2: Apply the "one-transaction rule" and determine which terms should run consecutively. This follows the standard principles in s 307(1) of the CPC, ensuring that the total NIP is proportionate to the overall criminality.
3. Step 3: Apply the "totality principle." The court must ensure the aggregate NIP is not "manifestly excessive" and reflects the totality of the offending behavior, while keeping the primary objective of prevention in mind.

What Was the Outcome?

The High Court dismissed the application for criminal revision. The court found that the District Judge’s determination of a nine-month NIP was not "palpably wrong" nor did it result in a "serious injustice." The court’s final order was stated as follows:

"For the above reasons, we dismissed the application for criminal revision." (at [77])

In applying the newly established framework to the facts, the High Court noted that the DJ had correctly identified the gravity of the applicant's conduct. The applicant had targeted vulnerable elderly victims in a series of unprovoked attacks. His history of similar offending (2012, 2015, 2021) was a critical factor. While the applicant’s intellectual disability did reduce his culpability, the court found that this did not necessitate a shorter NIP because the primary objective was prevention. The moderate-to-high risk of recidivism justified a term that would allow the Minister sufficient time to ensure the applicant received the necessary treatment and supervision.

The court specifically addressed the applicant's argument that the NIP should only be one and a half months. It held that such a short term would be "wholly inadequate" given the multiple victims and the repetitive nature of the violence. The DJ’s decision to run two four-month terms and one one-month term consecutively was consistent with the totality principle. The court also noted that the NIP is merely a maximum limit; it does not compel the Minister to confine the accused for the full nine months if the risk to the public is mitigated sooner through treatment or improved supervision arrangements.

No costs were awarded, as is standard in criminal revision matters of this nature. The applicant remained subject to the Minister's discretion regarding his confinement, with the nine-month NIP serving as the absolute legal ceiling for any such confinement order.

Why Does This Case Matter?

Abdul Ghufran bin Abdul Wahid v Public Prosecutor is a seminal decision for Singapore’s criminal justice system, particularly regarding the treatment of mentally vulnerable accused persons. Its significance can be categorized into three main areas:

1. Clarification of the "Limiting Term" Concept

The judgment provides the first high-level judicial interpretation of the "notional imprisonment period" introduced by the 2018 amendments to the CPC. By defining the NIP as a "limiting term" rather than a sentence, the court has clarified the constitutional and procedural boundaries of the fitness to plead regime. It ensures that the executive’s power to confine unconvicted persons is strictly circumscribed by a judicial assessment of what a proportionate sentence would have been. This protects the liberty of the individual while acknowledging the state's preventative role.

2. Primacy of Prevention in Non-Punitive Confinement

The court’s holding that prevention is the primary consideration for the NIP is a major doctrinal shift. It distinguishes the NIP exercise from standard sentencing, where retribution often takes center stage. This recognition allows the court to focus on the risk posed by the accused’s conduct rather than getting bogged down in the moral blameworthiness of a person who lacks the capacity to even stand trial. It provides a clear, safety-oriented objective for judges tasked with setting these terms.

3. Guidance on the Relevance of Mental Health

The decision resolves the tension regarding how to treat the accused's mental condition. By ruling that the condition should generally be ignored unless it has a material bearing on the notional sentence, the court prevents the NIP from becoming an overly complex medical-legal inquiry. It keeps the focus on the conduct that brought the accused before the court, ensuring that the NIP remains a reflection of the gravity of the alleged offences.

4. Practitioner Impact

For practitioners, the case provides a clear three-step framework (individual terms, consecutive terms, totality principle) that brings much-needed predictability to NIP hearings. It also clarifies the evidentiary burden, confirming that a full trial on the facts is not required, which streamlines the process for both the Prosecution and the Defence. The judgment serves as a reminder that while the NIP is "notional," it must still be grounded in established sentencing benchmarks and principles like the one-transaction rule.

5. Human Rights and Public Safety

Finally, the case illustrates the delicate balance Singapore law strikes between human rights and public safety. As noted by the court, quoting Ms Indranee Rajah, the procedures "balance the need to ensure that such persons are not a danger to themselves or others and the need to respect the fact that such persons have not been convicted of any offence." This judgment provides the judicial "teeth" to that balance, ensuring that confinement is neither arbitrary nor excessive.

Practice Pointers

• Focus on Prevention: When arguing for a specific NIP, practitioners should frame their submissions around the objective of prevention and public safety rather than traditional punitive factors like retribution or general deterrence.
• Mental Condition as a "Material Bearing": Counsel should only seek to rely on the accused's mental condition in the NIP calculation if they can demonstrate it would have clearly and significantly reduced the sentence upon conviction (e.g., by meeting the threshold for diminished responsibility).
• Benchmark Sentencing: Even though the NIP is not a formal sentence, the court will look to established sentencing benchmarks for the underlying offences. Practitioners should prepare "notional" sentencing submissions using these benchmarks as a starting point.
• Totality Principle: Always address the aggregate NIP. Even if individual terms are reasonable, the total NIP must not be "manifestly excessive" in light of the overall conduct and the primary goal of prevention.
• Supervision Plans: If seeking a discharge order under s 249(1) instead of a report to the Minister, the proposed supervision plan must be robust and capable of mitigating the risk of recidivism. The court will scrutinize the family's ability to provide "close and constant supervision."
• Evidentiary Basis: Be prepared to work with the "case for the prosecution" or undisputed facts. If key facts are disputed, the court will make a "notional" assessment; practitioners should focus on how those disputes would likely have been resolved at a trial.
• NIP as a Ceiling: Remind clients and families that the NIP is a maximum limit, not a mandatory minimum. The Minister has the discretion to release the accused earlier if their condition improves or risks are mitigated.

Subsequent Treatment

As this is a 2025 decision from a three-judge panel of the High Court, it currently stands as the leading authority on the determination of the notional imprisonment period in Singapore. It has clarified the application of the Criminal Justice Reform Act 2018 amendments to the fitness to plead regime. The ratio—that prevention is the primary consideration and that the NIP is a facilitative limiting term—is expected to be followed by all State Courts in future Stage 3 proceedings under s 249 of the CPC.
