Short answer: Bid rigging and price-fixing breach section 34 of the Competition Act 2004. The Competition and Consumer Commission of Singapore can demand documents, enter premises, interview staff and, after hearing representations, issue an infringement decision with a penalty of up to 10% of Singapore turnover for each year of infringement, capped at 3 years. Appeals go to the Competition Appeal Board.
Bid rigging in Singapore is not only a big-company problem. A 2024 enforcement case involved quotations worth about S$65,000 each and a penalty on an individual IT contractor. This guide explains what the Competition Act 2004 prohibits, what investigators can do, how the penalty is calculated, how leniency and the Fast Track Procedure work, and how an appeal runs. The regulator is the Competition and Consumer Commission of Singapore, which now uses the short name CCS on its website but which many business owners still know as CCCS.
Key facts at a glance
- Section 34 of the Competition Act 2004 prohibits agreements, decisions by trade associations and concerted practices that prevent, restrict or distort competition in Singapore.
- Maximum financial penalty: 10% of the undertaking’s Singapore turnover for each year of infringement, for up to 3 years (section 69(4)).
- Investigators may enter premises without a warrant; the usual 2 working days’ notice does not apply where the occupier is suspected of a section 34 infringement (section 64).
- Leniency: immunity for the first cartel member to come forward before an investigation starts, up to 100% off if first after it starts, and up to 50% off for later applicants.
- Fast Track Procedure: a further discount of up to 30%, applied after leniency (50% leniency plus 30% Fast Track gives a 65% overall reduction).
- Appeal to the Competition Appeal Board within 2 months of being notified of the decision (Competition (Appeals) Regulations, regulation 7(3)).

What does section 34 prohibit, and why is bid rigging singled out?
Section 34 of the Competition Act 2004 bans any agreement, trade association decision or concerted practice between businesses that has the object or effect of preventing, restricting or distorting competition in Singapore. Bid rigging is one of the clearest examples, because the rivalry a tender is meant to create is faked.
Section 34(2) lists conduct that may, in particular, fall foul of the prohibition. The forms SMEs most often meet are:
- Price-fixing: agreeing, directly or indirectly, on purchase or selling prices or other trading conditions (section 34(2)(a)).
- Bid rigging: arranging who wins a tender, for example through deliberately high “cover bids”, taking turns to win or agreeing not to bid.
- Market sharing: dividing customers, territories or sources of supply (section 34(2)(c)).
- Limiting output: agreeing to limit production, markets, technical development or investment (section 34(2)(b)).
Information exchange is not named in the list, but “concerted practice” covers informal coordination short of a signed agreement. Telling a rival what you intend to quote can be enough; see our article on exchanging pricing intentions. An infringing provision is void to that extent (section 34(3)), and the Act reaches agreements made outside Singapore if they infringe the prohibition (section 33(1)).
What powers does CCS have during an investigation?
CCS may investigate whenever it has reasonable grounds to suspect a section 34 infringement (section 62). Most of its powers can be used without going to court.
This is an administrative investigation under the Act, so the Rules of Court 2021 do not govern it. The courts come in at two points: a court issues any search warrant under section 65, and the General Division of the High Court hears appeals from the Competition Appeal Board under section 74.
| Power | Section | What it means for your company |
|---|---|---|
| Notice to produce documents or information | s 63 | CCS can require specified documents or information by a set time and in a set form, take copies, and ask present or past officers or employees to explain them. |
| Entry without a warrant | s 64 | Normally 2 working days’ written notice, but none is needed where the occupier is suspected of a section 34 infringement. Officers can require documents and electronic data. |
| Entry under a court warrant | s 65 | Reasonable force, search of persons and premises, seizure of documents and removal of equipment. A warrant lasts one month; seized documents may be kept for 3 months. |
| Oral examination | s 63(5), (6) | Individuals on the premises can be questioned; answers are written down, read back, interpreted if needed and signed. |
| Privilege and self-incrimination | s 66 | Privileged legal communications need not be produced. You cannot refuse to answer because it might incriminate you, though a statement made after claiming the privilege is inadmissible in most criminal proceedings. |
Failing to comply with a requirement (section 75), destroying or concealing requested documents (section 76), giving false or misleading information (section 77) and obstructing officers (section 78) are offences. If a company commits one with the consent or connivance of a director, manager or company secretary, or through their neglect, that officer is also guilty (section 81).
Who can be investigated and penalised?
Any “undertaking”: an individual, company, partnership or other entity capable of carrying on commercial or economic activities (section 2). Being small, new or a sole trader does not take you outside the Act.
The infringement decision of 5 September 2024 against Rei Securite Pte. Ltd. and Soh Chee Keong shows this. According to CCS, cover bids were submitted through two newly incorporated companies with no business activity on three invitations to quote called by Ngee Ann Polytechnic between January 2021 and November 2022, each worth S$63,000 to S$65,000. The bids went in on GeBIZ through those companies’ Corppass accounts. CCS penalised Rei Securite S$6,237 and Mr Soh, as an individual undertaking, S$2,550. The two cover-bid companies, struck off on 4 September 2023, were not addressees. The case began with a complaint from the polytechnic.
The lesson for small companies: low contract values do not keep you off the radar, and control of Corppass logins matters. Our guide to assigning Corppass e-service roles safely explains how to keep that control.
How does a bid rigging Singapore investigation unfold, step by step?
Most cases follow the same path. The Act sets no deadline for CCS to finish, so timing varies widely.
- Trigger: a complaint (often from the procuring agency), a leniency application by another cartel member, a whistle-blower or CCS’s own monitoring.
- First contact: a section 63 notice, or an unannounced visit under section 64 or a section 65 warrant.
- Evidence gathering: emails, chat messages, tender files and pricing workings, plus recorded interviews with directors and staff.
- Proposed Infringement Decision: CCS must give written notice to those likely to be affected and an opportunity to make representations (section 68(1)).
- Representations: the company, through its solicitors, can challenge the evidence, the market definition and the penalty calculation.
- Infringement decision: after considering representations, CCS may decide section 34 has been infringed (section 68(2)).
- Directions and penalty: CCS may order the agreement to be modified or ended and impose a penalty, but only if the infringement was intentional or negligent (section 69(2), (3)).
- Notification: affected persons must be notified within 14 days (section 70), and the 2-month appeal period runs from notification or publication, whichever is earlier.
From the first contact, stop routine deletion of emails and chats. Our article on litigation holds sets out a practical approach.
What documents will the company need to gather?
Requests usually cover the tenders under review and the people involved, often going back several years. Well-kept corporate records make the legal team faster and cheaper.
| Document | Why it matters | Usually held by |
|---|---|---|
| Tender submissions, drafts and pricing workings | Shows whether prices were set independently | Sales or tender team |
| Emails and chat messages with other bidders | Main evidence of agreements or information exchange | Staff and IT provider |
| Registers of directors, members and controllers | Shows who controlled the company and links between bidders | Company secretary |
| Board minutes on tenders, pricing and partnerships | Shows what management knew and approved | Company secretary |
| Corppass and GeBIZ user lists | Shows who submitted each bid | Corppass administrator |
| Financial statements by business year | Turnover drives the penalty calculation | Accountant |
| Subcontracting and consortium agreements | Legitimate cooperation can explain contact with other bidders | Management |
How much can the penalty be, and what drives the cost?
The cap is 10% of the undertaking’s Singapore turnover for each year of infringement, for up to 3 years (section 69(4)). Within that cap, CCS decides the amount.
Under the Competition (Financial Penalties) Order 2007, turnover is taken from the business year before the date of CCS’s decision, or the year before that if figures are unavailable. CCS’s published framework says it weighs seriousness, turnover in the affected market, duration, aggravating and mitigating factors, and deterrence. Unpaid penalties carry interest at 6%, calculated monthly, and CCS may allow instalments.
| Stage | Timeline | Cost drivers (assumption: no official fee applies to the investigation itself) |
|---|---|---|
| Section 63 notice | Deadline set in the notice | Document volume, device review, solicitor time |
| Unannounced visit | Same day | Whether a solicitor attends at once, IT support |
| Representations on the Proposed Infringement Decision | Period set by CCS | Complexity of evidence, market analysis, number of parties |
| Financial penalty | Due no earlier than the end of the appeal period (section 69(5)) | Turnover, duration, leniency and Fast Track discounts |
| Competition Appeal Board | Notice within 2 months; decided as soon as reasonably practicable (section 73(7)) | Prescribed filing fee, hearing length, expert evidence, costs orders |
| High Court appeal | Court timelines | Limited to points of law and the penalty amount |
Legal fees are quoted by the law firm. Before that conversation, pull together turnover by business year from your financial statements, because it sets the ceiling. Our free tools page is a good starting point on the compliance and records side.
Can leniency or the Fast Track Procedure reduce the penalty?
Yes. Leniency rewards cartel members who come forward and confess; the Fast Track Procedure rewards those who admit liability and help close the case. The two can be combined.
Under the CCS leniency programme:
- The first business to provide evidence before an investigation starts can receive immunity from financial penalties.
- The first to come forward after an investigation has started can receive up to 100% off.
- A business that is not first, or that started the cartel or coerced others, can receive up to 50% off if it applies before the Proposed Infringement Decision is issued.
- Every applicant must hand over all available evidence, cooperate continuously, stop participating (unless CCS directs otherwise) and admit the conduct unconditionally.
- Leniency Plus gives an extra reduction to a cooperating business that is first to report a completely separate cartel in another market.
Under the Fast Track Procedure, CCS applies a discount of up to 30% after other discounts such as leniency. The request must be made before an infringement decision is issued, and applying before the Proposed Infringement Decision is likely to earn more. Leniency is a race: only one firm can be first, so take advice quickly.
How do you appeal to the Competition Appeal Board and the High Court?
A party to an agreement CCS has found infringing may appeal to the Competition Appeal Board (section 71). For section 34 decisions and penalties, the notice of appeal must be lodged within 2 months of notification or publication, whichever is earlier (regulation 7(3)); the Board may extend time (regulation 7(4)).
The notice must set out the facts and grounds, attach the contested decision and the prescribed fee, and be lodged with 5 certified copies unless the Board directs otherwise (regulation 8). An appeal does not suspend the decision, but an appeal against the imposition or amount of a penalty suspends the penalty (section 71(3)).
The Board has a District Court’s powers over witnesses and documents, and may confirm or set aside the decision, remit it to CCS, or impose, revoke or vary the penalty (section 73). A further appeal lies to the General Division of the High Court only on a point of law or on the penalty amount (section 74(1)), with a further right of appeal as in the High Court’s original civil jurisdiction (section 74(4)).
Regulation 6 allows representation by an advocate and solicitor or another person the Board permits. In practice, appeals to the Board and the courts are conducted by a Singapore Advocate and Solicitor. If you receive a Proposed Infringement Decision, speak to a lawyer straight away.
Once a decision is final, anyone who suffered loss directly from the infringement, such as a buyer that overpaid, may sue for damages under section 86, within 2 years after the appeal periods end.
What does the company secretary prepare, and what does the solicitor handle?
The solicitor leads anything involving CCS, the Board or the courts. The company secretary or corporate service provider keeps the corporate side accurate and ready to produce.
| Company secretary or CSP | Solicitor |
|---|---|
| Current registers of directors, members and controllers | Responding to notices and attending unannounced visits |
| Board resolutions appointing lawyers and authorising a leniency or Fast Track application | Advising on whether and when to seek leniency |
| Minutes recording decisions and the date of any document hold | Representations on the Proposed Infringement Decision |
| Financial statements by business year | Appeals to the Board and the High Court, and any section 86 claim |
A CCS decision has no ACRA lodgement of its own, but a penalty or provision for one must be reflected when the financial statements are prepared and filed. If a director was involved, the board should also consider directors’ duties under section 157.
What are the common mistakes, and how can an SME bid safely?
Most SME cases start with habits that feel harmless: a call to a friendly rival, a related company asked to quote, or one person holding several Corppass logins. A short routine prevents most of them.
- Never ask a related or friendly company to quote high so that you win, even if the buyer wants “three quotes”.
- Disclose related bidders to the buyer; see our guide on a director’s spouse owning a proposed supplier.
- Prepare each bid internally, keep the workings, and never share intended prices with other bidders.
- Make sure no single person can submit bids for several companies.
- Put legitimate subcontracting or consortium arrangements in writing and tell the buyer where required.
- Delete nothing once CCS is involved; destroying requested documents is an offence under section 76.
- File changes of name, directors and shareholders with ACRA promptly so the buyer sees an accurate record.
- Have everyone who prepares bids sign a one-page policy on contact with other bidders each year.
Frequently asked questions
Is bid rigging a criminal offence in Singapore?
Under the Competition Act 2004, a section 34 infringement is dealt with by CCS through directions and financial penalties. Separate offences in Part 5, such as destroying documents or obstructing officers, can lead to criminal charges against the company and its officers.
Can CCS turn up at my office without warning?
Yes. The 2 working days’ notice under section 64 does not apply where the occupier is suspected of a section 34 infringement. With a court warrant under section 65, officers may also use reasonable force.
Can a director be penalised personally?
An individual can be penalised under section 69 if acting as an undertaking, as Mr Soh was in the 2024 Rei Securite decision. Officers can also be liable for Part 5 offences committed with their consent, connivance or neglect (section 81).
How is turnover measured for the penalty?
The cap uses Singapore turnover for each year of infringement, up to 3 years, taken from the business year before the date of CCS’s decision under the Competition (Financial Penalties) Order 2007.
When should we apply for leniency?
As early as possible. Immunity is only available before CCS starts investigating, and the 50% tier closes once the Proposed Infringement Decision is issued.
