Can a procuring agency change qualification criteria after bids are opened?

A Pakistani public procuring agency generally must evaluate bids according to the qualification and evaluation criteria communicated in the bidding documents, not introduce materially different requirements after bids have been opened. The Federal Public Procurement Rules, 2026, notified by S.R.O. 1658(I)/2026 on 28 September 2026, prescribe transparency and publication of eligibility, qualification and evaluation criteria. The legal analysis depends on the procurement method, stage, original documents and any authorised clarification or multi-stage revision mechanism. A legitimate request for evidence of an existing criterion is different from a newly invented condition that changes who can win.

Begin with the operative procurement regime

Federal agencies are subject to the applicable federal PPRA legislation and the new 2026 Rules where in force. Provincial authorities may follow distinct Punjab, Sindh, KP or Balochistan rules. An appeal should identify the particular procuring agency, source of funds and correct legal framework. A tender issued before new rules commenced can raise transitional questions requiring close examination of the applicable instruments and tender dates. Do not assume every public body uses the same regime.

Qualifications disclosed in bidding documents

Rule 34 of the federal 2026 Rules requires bidding documents to include qualification and evaluation criteria where applicable. Rules 22–24 also address prequalification, qualification and disqualification. The agency should state the educational, technical, financial and experience tests on which it will select a contractor. Secret post-opening standards undermine a bidder's ability to prepare a responsive offer. A subjective preference for a familiar supplier cannot be converted into a binding criterion after prices become known.

Clarification of existing credentials

A post-opening request for confirmation of an already required licence or a clearer copy of a balance sheet may be lawful where the regulations and solicitation permit it. The agency must not allow one bidder to cure a substantive deficiency through preferential treatment while rejecting others for the same defect. The distinction between clarification and material bid improvement is central. Obtain the actual correspondence and compare the instruction applied to every bidder.

Material post-opening amendment

A new minimum turnover threshold, additional completed-project experience or mandatory foreign manufacturer authorisation inserted after opening can change competition. Its legality must be assessed against the published criteria and procurement rules. If such a change would have altered which firms submitted bids, the fairness problem is particularly serious. The agency should not rely on internal committee minutes that bidders could never see as proof that the criterion was disclosed.

Permitted two-stage procedures

Some multi-stage procurement methods expressly permit discussion or revision of technical requirements before later proposals are opened. The federal 2026 Rules describe two-stage processes with procedural safeguards. In such a procurement, a lawful planned revision is not necessarily an arbitrary post-opening change. The agency must still follow the method actually selected and provide equal information and opportunity. A single-stage bid cannot simply be treated retroactively as a two-stage procedure to justify negotiations.

Eligibility versus technical scoring

Eligibility rules determine whether a bidder may participate, while evaluation criteria can determine the relative merits of compliant bids. Both need a disclosed and lawful basis. An agency may assess whether declared qualifications are genuine, but it should not invent a new weighted scoring factor because it prefers a particular technology. Compare qualification thresholds, technical scoring matrix and financial evaluation formula separately.

Evidence of discrimination

A bidder should preserve the invitation, bidding documents, addenda, bid-opening record, evaluation report and post-opening requests. Identify exactly which criterion was introduced or applied differently and how it affected evaluation. A bare claim that the winning bidder is favoured is weaker than proof that the agency added a condition matching only one bidder's credentials after seeing all offers. Detailed chronology and documentary comparison are decisive.

Official addenda before closing

Agencies can in appropriate circumstances issue lawful amendments before the bid deadline, subject to the rules on notice and sufficient time. That is different from privately changing criteria after opening. The bidder should determine when the addendum was actually communicated and whether it reached all participants through the prescribed platform. An unpublished internal note is not ordinarily the equivalent of a formal tender amendment.

Record of procurement proceedings

The 2026 Rules require relevant qualification and disqualification processes to be part of the record. The bidder should request the evaluation reasons and available procurement record through the proper channel. A record showing objective rejection for a false qualification statement can support the agency, while an undocumented new requirement can undermine its defence. Disclosure and confidentiality restrictions must be respected.

Disqualification for false information

Rule 24 of the new federal rules addresses materially inaccurate, incomplete or false eligibility information and failures to provide required information. An agency may lawfully reject a bidder on those grounds when conditions are met. A bidder cannot obtain relief simply by arguing that qualifications were checked after opening. The question is whether the agency applied existing legal criteria or invented new ones after the event.

Federal grievance procedure

Rule 65 of the federal 2026 Rules is identified as the route for relevant procurement grievances, with procedural conditions and time limits that must be checked directly. The aggrieved bidder should act before the process becomes irreversible rather than assume ordinary civil litigation can always repair an unlawful award. Provincial grievance routes can differ. A grievance should name the exact evaluation decision, rule and requested remedy.

Award stage and contract signature

A procurement grievance made before final award may lead to corrective evaluation or other lawful steps. Once a contract is executed, issues of third-party rights and contractual remedies can complicate relief. A bidder should seek any legally available interim protection promptly. A court may not automatically order the agency to award the contract to the complainant merely because evaluation contained an error. The appropriate remedy depends on materiality and procedure.

Public law principles

Transparency, equal treatment, fairness and non-arbitrariness inform procurement under the statutory scheme and constitutional principles where applicable. Article 199 can provide review of an unlawful public decision, subject to proper forum and alternative remedies. Courts do not ordinarily substitute a favoured technical score for every evaluation committee judgment. A challenge should establish violation of a disclosed criterion, statutory procedure or lawful decision-making standard.

A technical qualification example

A tender requires three comparable projects completed in five years. After bids open, the committee states that only projects performed in a particular foreign country count. If this geographic requirement was never disclosed and no statutory basis permits the change, it may be vulnerable. The bidder should attach the original qualification clause and relevant committee evaluation. The merits do not turn merely on its assertion that its projects were better.

A genuine verification example

The tender required a valid professional registration certificate. The winning bidder supplied a certificate whose validity is disputed. The agency requests verification from the regulator after opening. This may be lawful evaluation of an existing requirement rather than a new qualification. The agency should apply the same verification standards and document its reasoning. The unsuccessful bidder must distinguish authenticity checking from post-opening improvement.

Consequences and remedies

Depending on law and stage, relief can involve setting aside an improper evaluation, fresh evaluation under published criteria, rectifying discriminatory treatment or restarting procurement if the process is fundamentally compromised. A claimant should not demand automatic selection without showing that the legal method permits it. Costs, delay and legitimate government needs also matter in interim proceedings. The remedy should restore lawful competition rather than create another unfair advantage.

Opinion and recommended course

Material qualification criteria should be disclosed before bids and ordinarily cannot be invented after opening. Review the applicable 2026 federal or provincial rules, tender documents and evaluation record; distinguish lawful verification from substantive amendment and permitted multi-stage procedures. Raise a precise grievance promptly with documentary proof of the change and its effect.
