The Genesis of Procurement Disputes
In the world of government contracting, a Request for Proposal (RFP) is intended to be a foundational document that ensures a level playing field for all prospective bidders. It communicates the government’s requirements and establishes the basis upon which proposals will be judged. However, when the evaluation criteria within an RFP are poorly defined, subjective, or ambiguous, the entire procurement process is undermined. This ambiguity can create an environment where the agency’s decision-making process becomes opaque, leaving vendors to question whether the contract was awarded fairly and on the merits of the proposals.
A successful bid protest often hinges on an offeror’s ability to demonstrate that the agency’s evaluation was unreasonable or inconsistent with the solicitation’s stated terms. When those terms are vague, it opens the door for a protest by creating a scenario where the agency’s judgment can be challenged as arbitrary or capricious.
Vague evaluation criteria can manifest in several ways. For instance, an RFP might use subjective terms like “high quality” or “sufficient experience” without providing concrete metrics for how these attributes will be measured. Similarly, an agency may fail to specify the relative importance of different evaluation factors, leaving bidders to guess which aspects of their proposal will be most heavily weighted. This lack of clarity makes it difficult for vendors to prepare responsive proposals and for the agency to conduct a fair and impartial evaluation.
In such cases, a vendor who loses the contract may have strong grounds to protest, arguing that the agency’s evaluation was not based on a common, understandable standard, as required by procurement law. The U.S. Government Accountability Office (GAO) has consistently held that solicitations must contain enough information to allow bidders to compete intelligently and on equal terms.
A flawed evaluation process, stemming from ambiguous criteria, is a primary catalyst for a successful bid protest.
The core issue with vague criteria is that they can lead to a flawed evaluation. An agency might, for example, introduce unstated evaluation criteria during the review process, effectively changing the rules of the game after proposals have been submitted. This is a clear violation of procurement regulations, which mandate that agencies evaluate proposals based solely on the factors identified in the solicitation. A vendor that can demonstrate that the winning bidder was selected based on criteria not disclosed in the RFP has a strong case for a protest.
The key is to show that the agency’s evaluation was not only flawed but also prejudicial to the protesting vendor. This means the vendor must demonstrate that it had a substantial chance of winning the contract but for the agency’s improper evaluation.

Strategy

Deconstructing Ambiguity for a Winning Protest
A vendor that suspects an RFP’s evaluation criteria are too vague to ensure a fair competition must adopt a proactive and strategic approach. The first step is to thoroughly document the ambiguity. This involves identifying the specific language in the RFP that is unclear, subjective, or open to multiple interpretations. For example, if an RFP requires a “key personnel” plan but does not specify the required qualifications or experience, a vendor should note this lack of detail.
This documentation will be crucial evidence in a potential bid protest. It is also advisable to submit questions to the contracting officer during the designated question-and-answer period. This serves two purposes ▴ it may prompt the agency to clarify the evaluation criteria, and if the agency fails to provide a clear answer, it strengthens the vendor’s argument that the criteria were indeed vague.
Once a vendor has identified and documented the vague criteria, the next step is to craft a proposal that is as responsive as possible while also preserving the right to protest. This can be a delicate balance. The vendor should make a good-faith effort to meet the stated requirements, but it should also be prepared to argue that the ambiguity of the criteria made it impossible to fully comply. After the contract is awarded, if the vendor is unsuccessful, it should promptly request a debriefing from the agency.
A debriefing can provide valuable insights into how the agency evaluated proposals and may reveal that the agency used unstated criteria or applied the vague criteria in an unreasonable manner. This information can be the linchpin of a successful protest.

Common Grounds for Protest Based on Vague Criteria
There are several common grounds for a bid protest that arise from vague evaluation criteria. These include:
- Unstated Evaluation Factors ▴ The agency evaluated proposals based on criteria that were not disclosed in the RFP.
- Unreasonable Evaluation ▴ The agency’s evaluation was not reasonably based on the stated criteria, or the agency’s conclusions were inconsistent with the solicitation.
- Unequal Treatment ▴ The agency applied the evaluation criteria differently to different offerors, giving one vendor an unfair advantage.
- Lack of a Common Basis for Competition ▴ The RFP was so vague that it did not provide an intelligible and common basis for offerors to compete.
The following table illustrates the key differences between a strong and a weak basis for a protest based on vague criteria:
| Factor | Strong Basis for Protest | Weak Basis for Protest |
|---|---|---|
| Specificity of Claim | The protest identifies specific, ambiguous phrases in the RFP and demonstrates how they led to an unreasonable evaluation. | The protest makes a general claim of “unfairness” without pointing to specific language in the RFP. |
| Evidence of Prejudice | The vendor can show that it would have had a substantial chance of winning the contract if the criteria had been clear. | The vendor cannot demonstrate that the vague criteria had a material impact on the outcome of the procurement. |
| Timeliness | The protest is filed within the strict time limits set by the relevant protest forum (e.g. GAO, Court of Federal Claims). | The protest is filed after the deadline has passed. |

Execution

The Mechanics of a Successful Bid Protest
Launching a successful bid protest requires a meticulous and well-executed plan. The first step is to choose the appropriate forum for the protest. In the United States, vendors typically have three options ▴ an agency-level protest, a protest at the Government Accountability Office (GAO), or a protest at the U.S. Court of Federal Claims (COFC). Each forum has its own set of rules, procedures, and timelines, so it is essential to choose the one that is best suited to the specific circumstances of the protest.
An agency-level protest is often the quickest and least expensive option, but it may not be the most impartial. The GAO is an independent, non-partisan agency that provides a more formal and structured protest process. The COFC is a federal court that can hear bid protests and provides the most formal and extensive review process.
A successful protest is built on a foundation of clear evidence, persuasive legal arguments, and a deep understanding of procurement law.
Once the forum has been chosen, the next step is to file the protest. The protest must be in writing and must include a detailed statement of the legal and factual grounds for the protest. This is where the documentation of the vague evaluation criteria and the evidence gathered during the debriefing will be critical. The protest should clearly explain how the agency’s actions violated procurement law and how the vendor was prejudiced by those actions.
It is highly advisable to seek the assistance of an experienced government contracts attorney to draft and file the protest. An attorney can help ensure that the protest is timely, well-pleaded, and persuasive.

A Step-by-Step Guide to Filing a Bid Protest
The following is a general overview of the steps involved in filing a bid protest at the GAO:
- Initial Assessment ▴ The vendor and its legal counsel should conduct a thorough assessment of the merits of the potential protest. This includes reviewing the RFP, the vendor’s proposal, the agency’s award decision, and any debriefing materials.
- Timely Filing ▴ The protest must be filed within the strict time limits set by the GAO. Generally, a protest must be filed within 10 days of when the protester knew or should have known of the grounds for protest.
- Content of the Protest ▴ The protest must be in writing and must include the following information:
- The name, address, and telephone number of the protester.
- The solicitation or contract number.
- A detailed statement of the legal and factual grounds of the protest, including copies of relevant documents.
- A statement of the form of relief requested.
- Agency Report ▴ After the protest is filed, the agency is required to submit a report to the GAO that responds to the allegations in the protest.
- Comments on the Agency Report ▴ The protester has the opportunity to file comments on the agency report, rebutting the agency’s arguments and providing additional evidence in support of the protest.
- GAO Decision ▴ The GAO will issue a written decision on the protest, either sustaining it, denying it, or dismissing it. If the protest is sustained, the GAO may recommend that the agency take corrective action, such as re-evaluating proposals or terminating the contract.
The following table provides a more detailed look at the key elements of a successful bid protest:
| Element | Description |
|---|---|
| Standing | The protester must be an “interested party,” which generally means a vendor that submitted a proposal and had a substantial chance of winning the contract. |
| Timeliness | The protest must be filed within the strict time limits set by the relevant protest forum. |
| Valid Grounds for Protest | The protest must be based on a valid legal argument, such as a violation of a procurement statute or regulation. |
| Prejudice | The protester must demonstrate that it was prejudiced by the agency’s actions, meaning that it had a substantial chance of winning the contract but for the agency’s errors. |

Reflection

Upholding the Integrity of Public Procurement
The issue of vague evaluation criteria in RFPs is more than just a matter of legal technicalities. It strikes at the heart of the principles of fairness, transparency, and accountability that are supposed to govern public procurement. When agencies fail to provide clear and objective standards for evaluating proposals, they not only create an uneven playing field for vendors but also risk squandering taxpayer money on contracts that may not provide the best value to the government. A successful bid protest, therefore, can serve as a powerful tool for holding agencies accountable and for promoting a more fair and competitive procurement system.
For vendors, the decision to file a bid protest is not one to be taken lightly. It can be a costly and time-consuming process, and there is no guarantee of success. However, when the circumstances warrant it, a protest can be a necessary and effective way to protect a vendor’s rights and to ensure that the procurement process is conducted in accordance with the law. Ultimately, a robust and accessible bid protest mechanism is essential for maintaining the integrity of the public procurement system and for ensuring that the government gets the best possible value for its money.
