Public Procurement Contracts Lawyer | Advisory Support Across Bidding, Performance, and Disputes

Summary

Public procurement contracts are subject to the Act on Contracts to Which the State is a Party (국가를 당사자로 하는 계약에 관한 법률) or the equivalent local government act, layered on top of the general Civil Act provisions on contracts. This means a company can lose a contract opportunity or face a business-threatening sanction not because it did anything wrong in a normal commercial sense, but because it failed to follow a procedural requirement — a document submission deadline, a qualification standard, or an inspection procedure. Because restriction on qualification for bidding can shut a company out of all public contracts for months or years, early advisory input at the bidding stage is often more valuable than fighting a sanction after the fact. This page is written for companies at any of those stages — preparing a bid, mid-performance dispute, or already facing a sanction notice.

Public Procurement Contracts | Bid Participation, Qualification Screening, and Award Disputes

Most disputes at the bidding stage come down to whether the bidding notice's terms, the qualification screening criteria, or the evaluation process were applied consistently and lawfully. A company that believes it was wrongly excluded has a limited window to act.

Bid disqualification and objections to bidding notice terms

Public institutions must specify bid participation qualifications, required documents, and evaluation criteria in the bidding notice, and contracting authorities generally cannot apply standards beyond what the notice states (국가를 당사자로 하는 계약에 관한 법률 제10조 및 시행령). If a bid is disqualified for a document defect or a qualification issue, the first question is always whether the notice's requirement was clear and whether the defect was actually material. Many disqualifications are contested successfully simply by showing the notice was ambiguous or that the same standard was not applied to other bidders.

Successful bidder designation and award cancellation

Once a successful bidder is designated, a losing bidder may raise an objection or file a request for deliberation if it believes the evaluation was flawed, but these remedies typically have short filing periods measured in days from notification. Because contracting authorities have discretion in evaluating price, technical scores, and past performance under the relevant regulations, a challenge needs to identify a specific procedural or standard-application defect rather than simply disagreeing with the score. Acting within the objection period matters more here than building an exhaustive case, since the window closes quickly.

Joint ventures, subcontracting restrictions, and eligibility for participation

Companies structuring a joint supply agreement or planning subcontracting need to check the restrictions on joint contracting and mandatory subcontracting rules before submitting a bid, not after — a structure that looks fine commercially can violate the joint contract operating guidelines and taint the entire bid. Reviewing the consortium or subcontracting structure against the bidding notice and applicable guidelines before submission avoids having to unwind a defective bid later.

Public Procurement Contracts | Contract Performance, Change Orders, and Claims for Additional Payment

Disputes during performance usually center on whether a change in circumstances — added work, delayed site handover, price fluctuation, or a force majeure event — entitles the contractor to an adjustment of the contract price or deadline, and whether the contracting authority's inspection and acceptance decisions were properly made.

Contract price adjustment for price fluctuation and additional work

The Act on Contracts to Which the State is a Party allows adjustment of the contract price where prices of materials or labor fluctuate significantly, or where the scope of work changes (국가를 당사자로 하는 계약에 관한 법률 제19조 및 시행령 제64조 등). In practice, the dispute is rarely about whether adjustment is possible in principle — it is about whether the contractor properly documented and requested the adjustment within the procedure the contract and regulations require, since a late or informal request is often rejected regardless of merit.

Delay penalties (지체상금) and force majeure defenses

When a contractor misses the completion date, the contracting authority typically assesses a delay penalty calculated under the contract's delay penalty rate. Whether that penalty can be reduced or excluded depends on whether the delay was caused by the contracting authority's own default (e.g., late site handover) or by a force majeure event recognized under the contract terms — this causal link is where most delay penalty disputes are actually fought, not the existence of delay itself.

Inspection, acceptance, and payment disputes

A public institution's refusal to accept completed work or its decision to withhold part of the payment must be based on an actual defect identified through the inspection procedure set out in the contract, not on unilateral dissatisfaction. Where the contractor disputes the inspection result, documenting the condition of the deliverable at the time of inspection becomes central to any later claim for payment.

Public Procurement Contracts | Restriction on Qualification for Bidding and Other Sanctions

Restriction on qualification for bidding (부정당업자 제재) is the sanction companies fear most, because it can block participation in all public contracts nationwide for a set period. Understanding when it applies and how to respond procedurally is often more important than the underlying factual dispute.

Grounds for restriction on qualification for bidding

Contracting authorities may restrict a company's qualification to bid for a fixed period where it engages in conduct such as bid rigging, submitting false documents, breaching the contract without justification, or causing harm to the public interest in performance (국가를 당사자로 하는 계약에 관한 법률 제27조). Because the statute lists broad categories of misconduct, much of the dispute is about whether the specific facts actually fit the ground the authority cited, or whether the authority is stretching a minor issue into a serious category.

Proportionality of the sanction period

Even where some ground for restriction exists, the length of the restriction period must be set according to the severity criteria in the relevant enforcement regulations, and disproportionately long periods can be challenged separately from the underlying finding of misconduct. Prior compliance history, the degree of actual harm caused, and cooperation during the process are commonly raised factors in seeking a reduced period.

Practical effect: exclusion from bids nationwide

A restriction on qualification for bidding issued by one public institution is generally recognized across other public institutions as well, meaning a company effectively cannot participate in any public bid during the restriction period — this nationwide effect is why many companies engage a public contract lawyer in Seoul or elsewhere as soon as a sanction notice arrives, rather than waiting to see how the underlying dispute develops.

⚠ Filing periods for administrative appeal and litigation are strict

A restriction on qualification for bidding is an administrative disposition, and a company that wants to contest it generally must file an administrative appeal or administrative litigation within 90 days of being notified of the disposition (행정심판법 제27조, 행정소송법 제20조). Missing this period generally forecloses the challenge regardless of how strong the underlying argument is, so the notice should be reviewed as soon as it arrives.

Public Procurement Contracts | From Initial Review to Resolution

Document and stage review
The starting point is reviewing the bidding notice, contract, correspondence with the contracting authority, and any disposition notice to identify exactly which procedural stage the dispute is at and what deadlines apply.

Deadline mapping
Because objection periods, appeal periods, and litigation filing periods in public contract matters are often short and non-negotiable, the review immediately flags which dates are fixed and which decisions can wait.

Response strategy
Depending on the stage, this may mean drafting an objection to a bidding notice, preparing a request for deliberation on an award decision, negotiating a contract price adjustment, or preparing an administrative appeal against a restriction on qualification for bidding.

Filing and representation
Where a formal filing is needed — an objection, an administrative appeal, or administrative litigation — the firm prepares and files the documents and represents the company through hearings or deliberation sessions.

Follow-up and compliance
For companies that deal with public contracts regularly, the advisory relationship often continues after resolution, reviewing future bidding notices and contract terms to reduce recurrence of the same issue.

Public Procurement Contracts | How Fees Are Set

Advisory retainer
For ongoing review of bidding notices, contract drafts, and day-to-day questions, fees are typically structured as a monthly or per-matter advisory retainer rather than a one-time fee, reflecting the recurring nature of public contract compliance.

Case-based retainer
For a specific dispute — an objection, an administrative appeal against restriction on qualification for bidding, or litigation — the retainer is set based on the complexity of the matter, the number of contracting authorities or bids involved, and the procedural stage at which the firm is engaged.

Success fee
Where applicable, a success fee may be agreed in proportion to the amount of additional payment recovered or the reduction achieved in a restriction period, agreed in advance and in writing.

Disbursements
Costs such as document translation, expert review of technical specifications, and filing fees for administrative appeal or litigation are billed separately as actual expenses incurred.

Public Procurement Contracts | Self-Check by Situation

1️⃣ Before Submitting a Bid

Have you confirmed every qualification requirement stated in the bidding notice, not just the ones that seem obvious?
If you are forming a joint venture or subcontracting arrangement, have you checked it against the joint contract operating guidelines before submission?
Do you have a clear record of when and how each required document was submitted?
If a prior bid was disqualified, did you identify the exact clause of the notice that was applied against you?

2️⃣ During Contract Performance

Have you documented the contracting authority's role in any delay (e.g., late site handover) as it happens, not after the fact?
If prices or labor costs have fluctuated significantly, have you submitted a formal request for price adjustment within the required procedure?
Do you have contemporaneous records of the condition of deliverables at the time of inspection?
Are you tracking the deadline for any delay penalty dispute separately from the main performance dispute?

3️⃣ After Receiving a Sanction Notice

Have you confirmed the exact date you received the disposition notice, since the appeal period runs from that date?
Does the ground cited in the notice actually match the facts, or is it a broader category than what happened?
Have you gathered evidence relevant to the proportionality of the sanction period, such as prior compliance history?
Have you checked whether the sanction, once finalized, will affect contracts with other public institutions beyond the one that issued it?

Frequently Asked Questions

Q. My bid was disqualified for a minor document error. Can this be reversed?

A. It depends on whether the requirement was clearly stated in the bidding notice and whether the error is genuinely material to the evaluation. Disqualifications for ambiguous requirements or inconsistently applied standards are the ones most often successfully contested.

Q. How long do I have to object to a bid award decision?

A. Objection and request-for-deliberation periods are generally measured in days from the date of notification, not weeks, so the notice should be reviewed immediately upon receipt. The exact period depends on the specific procedure and regulation that applies to the contracting authority involved.

Q. What is restriction on qualification for bidding and how long does it last?

A. It is a disposition under which a contracting authority bars a company from participating in public bids for a fixed period, issued where misconduct such as bid rigging or contract breach is found (국가를 당사자로 하는 계약에 관한 법률 제27조). The length of the period depends on the severity criteria in the enforcement regulations and can sometimes be reduced through an administrative appeal.

Q. Can I keep bidding while I'm contesting a restriction on qualification for bidding?

A. Filing an administrative appeal or litigation does not automatically suspend the disposition, so a separate request for a stay of execution is generally needed if the company wants to continue bidding during the dispute. Whether a stay is granted depends on the urgency and the likely harm shown.

Q. Does a restriction issued by one government agency affect my contracts with other agencies?

A. Yes, generally a restriction on qualification for bidding issued by one public institution is recognized across other public institutions as well, which is why the practical effect is closer to a nationwide bidding ban than a single-agency penalty.

Q. Can I claim additional payment if raw material prices rose sharply after I signed the contract?

A. The Act on Contracts to Which the State is a Party provides for contract price adjustment where price fluctuations meet certain thresholds, but the adjustment generally must be formally requested through the procedure set out in the contract and regulations (국가를 당사자로 하는 계약에 관한 법률 제19조). A request made informally or after the relevant period may be rejected even if the price fluctuation itself is undisputed.

Q. Can I dispute a delay penalty if the delay was caused by the public institution itself?

A. Yes, if the delay was caused by the contracting authority's own default, such as late site handover or delayed provision of necessary materials, this is a common and often successful ground to reduce or exclude a delay penalty. The key is documenting the causal link between the authority's conduct and the delay at the time it occurred.

Q. What should I check before entering a joint venture bid with another company?

A. You should review the proposed structure against the joint contract operating guidelines and the specific bidding notice before submission, since a structure that is commercially reasonable can still violate joint contracting restrictions and disqualify the entire bid.

Q. The public institution refused to accept my completed work. What can I do?

A. The refusal must be based on an actual defect identified through the contractual inspection procedure, not general dissatisfaction, so the first step is reviewing the inspection record and documenting the actual condition of the deliverable at the time it was submitted.

Q. Do I need a lawyer just to review a bidding notice before I submit?

A. It is not required, but for companies bidding regularly or on large contracts, an advisory review can catch qualification or structural issues (such as joint venture or subcontracting problems) before submission, which is usually far more effective than contesting a disqualification afterward.

Q. What happens if I miss the appeal period for a restriction on qualification for bidding?

A. Once the 90-day period for administrative appeal or litigation passes, the disposition generally becomes final and can no longer be challenged on the merits, regardless of how strong the underlying argument might have been (행정심판법 제27조, 행정소송법 제20조). This is why reviewing a disposition notice immediately upon receipt matters more than building a complete case first.

Q. Is a public contract dispute handled differently from a private commercial contract dispute?

A. Yes — public contracts are layered with statutory rules on bidding, qualification, and sanctions that do not exist in private contracts, and many disputes turn on procedural compliance with those statutes rather than on the general contract principles under the Civil Act alone.
