What Is This Legislation About?
The Significant Investments Review (Composition of Offences — Minister for Defence) Regulations 2025 (“SIRA Defence Composition Regulations”) is a piece of subsidiary legislation made under the Significant Investments Review Act 2024 (“SIRA Act”). In plain language, it identifies certain offences under the SIRA Act that can be “compounded” — meaning they may be resolved through the payment of a composition sum rather than proceeding through the full criminal process.
The Regulations are specifically tied to the role of the Minister for Defence. They do not create new substantive investment-review rules by themselves; rather, they operationalise the enforcement mechanism in the SIRA Act by prescribing which offences are eligible for composition and by defining the relevant “designated entities” for the Defence-related context.
Practically, this means that where a relevant offence occurs involving the specified Defence-linked entities, the enforcement authority may offer composition (subject to the statutory conditions in the SIRA Act and the limitations in these Regulations). This can reduce uncertainty, shorten resolution timelines, and avoid the costs and publicity of prosecution—while still ensuring that breaches of the Act have consequences.
What Are the Key Provisions?
Section 1 (Citation and commencement) provides the formal commencement date and citation. The Regulations come into operation on 28 February 2025. For practitioners, this matters for determining whether an alleged breach falls within the period governed by these composition rules and for aligning enforcement steps with the correct version of the subsidiary legislation.
Section 2 (Definition of “designated entity”) defines the entities to which the Defence composition framework is anchored. The Regulations define “designated entity” to include the following companies:
- ST Engineering Marine Ltd.
- ST Engineering Land Systems Ltd.
- ST Engineering Defence Aviation Services Pte. Ltd.
- ST Engineering Digital Systems Pte. Ltd.
- Sembcorp Specialised Construction Pte. Ltd.
This definition is important because it signals that the Defence-related composition regime is not universal across all regulated parties under the SIRA Act. Instead, it is focused on particular entities that are relevant to national defence and security considerations. In enforcement and compliance work, counsel will typically map the client’s corporate group structure against this definition to determine whether the Minister for Defence composition pathway is available.
Section 3 (Compoundable offences) is the core operative provision. Section 3(1) states that, subject to paragraph (2), for the purposes of section 53(2) of the Act, each offence specified in the Schedule is prescribed as a compoundable offence. In other words, the Schedule is the definitive list of offences that can be compounded in the Defence context.
Section 3(2) (Continuing offences excluded) introduces a key limitation: a continuing offence is not a compoundable offence. This is a significant practical constraint. A “continuing offence” generally refers to an offence that persists over time due to ongoing conduct or an ongoing state of affairs. By excluding continuing offences from composition, the Regulations indicate that where non-compliance is ongoing (rather than a discrete past breach), the enforcement authority should not resolve the matter through composition alone. Instead, prosecution or other enforcement measures may be more appropriate to address the continuing nature of the breach.
The Schedule (Compoundable offences) is referenced as containing the offences that are prescribed as compoundable. Although the extract provided does not reproduce the Schedule’s detailed list, the structure of the Regulations makes clear that the Schedule is determinative. For a practitioner, the Schedule should be reviewed alongside the relevant provisions of the SIRA Act to understand:
- which specific offences are eligible for composition;
- whether the offences relate to notification, approval, conditions, or other compliance duties under the SIRA Act; and
- how the “designated entity” definition interacts with those offences.
How Is This Legislation Structured?
The Regulations are structured in a straightforward, enforcement-focused manner:
- Part/Section 1: Citation and commencement (administrative commencement mechanics).
- Section 2: Definitions, specifically defining “designated entity” for the Defence-related composition framework.
- Section 3: The operative rule that prescribes offences as compoundable, subject to the exclusion of continuing offences.
- Schedule: The list of offences that are compoundable (the substantive content for enforcement eligibility).
Notably, the Regulations do not contain complex procedural rules within the text provided. Instead, they rely on the composition framework in the SIRA Act (including section 53(2) and the broader composition provisions) and use the Schedule to specify which offences fall within the compoundable category for the Minister for Defence.
Who Does This Legislation Apply To?
These Regulations apply in the context of the SIRA Act’s enforcement and composition regime, specifically where the Minister for Defence is the relevant authority. The Regulations define “designated entity” to include five specified companies within the ST Engineering group and Sembcorp Specialised Construction Pte. Ltd. Accordingly, the Defence composition pathway is most relevant to these entities and, in practice, to their corporate groups and transactions that trigger the SIRA Act’s obligations.
While the Regulations themselves only define “designated entity,” the underlying SIRA Act likely imposes obligations on persons and entities involved in significant investments, including duties relating to notification, review, and compliance with conditions. Therefore, counsel should consider not only the named “designated entities” but also whether the client’s conduct involves those entities (for example, through shareholding, control, or other transaction structures) such that the offence provisions in the Schedule are engaged.
Why Is This Legislation Important?
Although the Regulations are relatively short, they are important because they directly affect enforcement outcomes. The ability to compound offences can materially change the risk profile of non-compliance. Composition typically offers a faster, more controlled resolution than prosecution, which can involve lengthy proceedings, evidential burdens, and reputational impacts.
However, the Regulations also reflect a clear policy boundary: continuing offences cannot be compounded. This means that where a breach is ongoing—such as a persistent failure to comply with an obligation or a continuing contravention—composition may not be available. Practitioners should therefore assess whether the alleged offence is a discrete event or a continuing breach, because that classification can determine whether composition is a realistic option.
From a compliance perspective, the Regulations underscore the need for robust governance around the SIRA Act’s requirements for designated entities. Counsel advising ST Engineering-related entities or Sembcorp Specialised Construction should ensure that internal controls can detect and prevent breaches early, document corrective actions, and preserve the possibility of composition where appropriate. From an enforcement perspective, the Regulations provide clarity on which offences are eligible for composition under the Defence authority, enabling more predictable engagement between regulators and affected parties.
