The Appellant, the Animal Protection Institute (“the Institute”), appeals the Waco Federal District Court’s dismissal of its motion to intervene in Doe v. Glickman, CV No. W-99-CA-335. For the reasons stated below, we Reverse.
1. Factual and Procedural Background.
This case arises out of the Institute’s request that the United States Department of Agriculture (“USDA”), acting through Wildlife Services and the Animal Plant Health Inspection Service, disclose information concerning the Livestock Protection Collar Program (“Program”), including the names and locations of the Program’s participants. A livestock protection collar (“Collar”) is a device designed to protect livestock by killing their predators. The Collar fastens around the livestock’s neck and has a pouch that contains sodium fluoroacetate, commonly known as Compound 1080. When predators such as coyotes or mountain lions attack livestock, they usually bite the domesticated animal’s neck. When a predator bites the neck of a domesticated animal equipped with a Collar, the Collar releases sodium fluoroacetate, thereby poisoning and killing the predator.
On November 18, 1998, pursuant to the Freedom of Information Act (“Act”), 1 the Institute formally requested the USDA to disclose information concerning the Program and the Collar’s use in seven states. The USDA disclosed the requested information concerning the Program and the Collar’s use, but only as to five of the seven states. The USDA refused to dis *374 close any of the information concerning the Program or the Collar’s use in Texas or New Mexico. The Institute filed a supplemental request with the USDA seeking that information. On May 27, 1999, the USDA disclosed some information concerning the Program and the Collar’s use in Texas and New Mexico, but did not disclose the names and locations of the Program’s participants from those states (“Identifying Information”). The USDA withheld the Identifying Information pursuant to 5 U.S.C. § 552b (c)(6). 2
The Institute filed an administrative appeal. The USDA did not respond. In response, on August 31, 1999, the Institute sued the USDA in Washington, D.C. District Court, Animal Prot. Inst. v. Wildlife Services, CV No. 99-2324 (“D.C.Lawsuit”), seeking the disclosure of the Identifying Information pursuant to the Act. Because of the D.C. Lawsuit, the USDA prepared to disclose the Identifying Information to the Institute on October 29, 1999.
On October 29, 1999, counsel for the American Farm Bureau Federation (“Plaintiffs Counsel”) learned that the USDA intended to disclose the Identifying Information that afternoon. Plaintiffs Counsel contacted the Assistant United States Attorney (“AUSA”) representing the USDA and asked the AUSA to delay disclosing the Identifying Information until November 3, 1999 so that she could evaluate her client’s legal options. The AUSA pledged not to disclose the Identifying Information that afternoon, but warned that it was possible that the USDA would disclose the Identifying Information on November 1, 1999.
On November 1, 1999, before the USDA disclosed the Identifying Information, the Appellees, aware of the D.C. Lawsuit and rather than intervene in that lawsuit, filed a separate lawsuit against the USDA in Waco Federal District- Court (‘Waco Court”), Doe v. Glickman, CV No. W-99CA-335 (Waco Lawsuit”). The Appellees sought a temporary restraining order (“TRO”) to enjoin the USDA from disclosing the Identifying Information. They alleged that the disclosure would be a clearly unwarranted invasion of privacy, not outweighed by the public’s interest in the Identifying Information. At 3:00 p.m. that same day, the Waco Court granted the TRO ex parte. Three days later, on November 4, 1999, the Institute learned of the Waco Lawsuit through a press release announcing the issuance of the TRO. On November 15, 1999, the Waco court entered a stipulated and agreed preliminary injunction.
The USDA filed motions with the Waco Court to transfer venue in the Waco Lawsuit to the Washington, D.C. District Court (“D.C.Court”) and, alternatively, stay the Waco Lawsuit pending the D.C. Lawsuit. The Appellees responded. On January 20, 2000, the Waco Court denied both of the USDA’s motions.
Having failed to stay or transfer the Waco Lawsuit to the D.C. Court, the USDA filed a motion to stay the D.C. Lawsuit with the D.C. Court. The Institute filed a response opposing the USDA’s motion. After considering the motion and response, the D.C. Court, on June 13, 2000, stayed the D.C. Lawsuit pending the outcome of the Waco Lawsuit. The Institute, on July 12, 2000, filed a motion to intervene in the Waco Lawsuit with the Waco Court. The Institute sought an intervention of right or, alternatively, a per *375 missive intervention. The Appellees opposed the Institute’s motion, arguing that it was untimely and that allowing the Institute to intervene would be prejudicial. On August 8, 2000, the Waco Court denied the Institute’s motion to intervene. On August 28, 2000, the Institute filed its notice of interlocutory appeal from the denial of its motion to intervene in the Waco Lawsuit.
2. Discussion.
This appeal presents us with the issue of whether we should allow the Institute to intervene in the Waco Lawsuit. The Institute argues that it is entitled to an intervention of right or, alternatively, to a permissive intervention. The Appellees contend that the Institute is neither entitled to an intervention of right or a permissive intervention since the Institute’s motion to intervene was untimely and the USDA can adequately protect the Institute’s interests. Because of our resolution of this case, we need not reach the merits of whether the Institute is entitled to a permissive intervention.
2.1 The Institute is entitled to an intervention of right.
Federal Rule of Civil Procedure 24(a) governs interventions of right. Fed. R. Civ. P. 24(a);
Ruiz v. Estelle,
Upon timely application anyone shall be permitted to intervene in an action ... when the applicant claims an interest relating to the property or transaction which is the subject of the action and the applicant is so situated that the disposition of the action may as a practical matter impair or impede the applicant’s ability to protect that interest, unless the applicant’s interest is adequately represented by existing parties.
Fed. R. Civ. P. 24(a) (2000). “Federal courts should allow intervention where no one would be hurt and the greater justice could be attained.”
Sierra Club v. Espy,
2.11 The Institute’s motion to intervene was timely.
“The requirement of timeliness is not a tool of retribution to punish the tardy would-be intervener, but rather a guard against prejudicing the original parties by the failure to apply sooner.”
Espy,
*376
When determining whether a motion to intervene is timely, a court must consider the following four factors: (1) how long the potential intervener knew or reasonably should have known of her stake in the case into which she seeks to intervene; (2) the prejudice, if any, the existing parties may suffer because the potential intervener failed to intervene when she knew or reasonably should have known of her stake in that case; (3) the prejudice, if any, the potential intervener may suffer if the court does not let her intervene; and (4) any unusual circumstances that weigh in favor of or against a finding of timeliness.

Ford,
If a court denies a motion to intervene because it was untimely, we generally review this decision, and only this decision, for an abuse of discretion.
Ruiz,
The Waco Court found that the motion was untimely and that the USDA adequately protected the Institute’s interests.
3
It did not, however, expressly reference any of the four timeliness factors. Thus, it would appear that we should review the timeliness element
de novo
and not for an abuse of discretion.

Ruiz,
2.111 The Institute filed its motion to intervene approximately one month after it became aware of its stake in the Waco Lawsuit.
“Courts should discourage premature intervention [because it] wastes judicial resources.”
Espy,
It is undisputed that the Institute has a stake in the Waco Lawsuit. The question, then, is when the Institute’s stake materialized, and thus, when it knew or reasonably should have known of its stake in the Waco Lawsuit.
See Espy,
In the D.C. Lawsuit, the Institute seeks to compel the USDA to disclose the Identifying Information. In the Waco Lawsuit, the Appellees seek to prevent the USDA from disclosing the Identifying Information. The substantive issue underlying both the D.C. and Waco Lawsuits is the same-does the public’s interest in the Identifying Information outweigh the potential invasion of privacy that could result if the USDA were to disclose that information (“Issue”). 4
The D.C. Court stayed the D.C. Lawsuit, the first lawsuit, pending the outcome of the Waco Lawsuit, the second lawsuit, on June 13, 2000. Until then, the D.C. Lawsuit could have been the lawsuit where the Issue would be decided. The stay made it clear that the Waco Lawsuit would be the lawsuit where the Issue would be decided. The stay, further, made it clear that the Institute would have to become a party to the Waco Lawsuit, if it wanted to be heard on the Issue. Thus, we conclude that the Institute’s stake in the Waco Lawsuit materialized on June 13, 2000.
5
See Espy,
The Institute filed its motion to intervene in the Waco Lawsuit on July 12, 2000, before trial and any final judgment. We cannot say that this delay is unreasonable.
See Edwards,
In
Stallworth,
we held that the trial court abused its discretion when it “mistakenly used an unspecified time when it supposed that the appellants must have learned of the pendency of the action rather than the time when they knew or should have known of their [stake] in the action as its starting point in assessing whether they acted promptly to protect themselves.”
Stallworth,
2.112 The existing parties to the Waco Lawsuit would not have suffered any less prejudice had the Institute filed sooner.
The second factor is concerned “only [with] that prejudice which would result from the would-be intervener’s failure to request intervention as soon as he knew or reasonably should have known about his [stake] in the action.”
Stall-worth,
As stated above, courts should ignore the likelihood that intervention may interfere with orderly judicial processes.
Stallworth,
2.113 If the Institute is not allowed to intervene, it will be prejudiced.
The third factor focuses on the prejudice the potential intervener would
*379
suffer if not allowed to intervene. In the Waco Lawsuit, the Waco Court could rule in favor of the Appellees. If it does, the USDA will be prohibited, by court order, from disclosing the Identifying Information that the Institute seeks. If not allowed to intervene, the Institute, as a non-party, will not be able to participate in the trial concerning that ruling nor will it be able to appeal that ruling.
Edwards,
2.114. The existence of the D.C. Lawsuit is an unusual circumstance that weighs in favor of a finding of timeliness.
Finally, we must decide whether any unusual circumstances weigh in favor of or against a finding that the motion to intervene was timely. The Institute filed its lawsuit in the D.C. Court. 6 The Appellees were aware of the D.C. Lawsuit. Nonetheless, the Appellees chose to file their lawsuit in the Waco Court, rather than intervene in the existing D.C. Lawsuit. Until the D.C. Court stayed the D.C. Lawsuit pending the outcome of the Waco Lawsuit, either lawsuit could have been the lawsuit where the Issue would be decided. This fact is an unusual circumstance that weighs in favor of intervention. Because each of the foregoing elements weighs in favor of a finding of timeliness, we find that the Institute’s motion to intervene was timely.
2.12 The interest the Institute asserts is related to the transaction that forms the basis of the controversy in the Waco Lawsuit.
A potential intervener asserts an interest that is related to the property or transaction that forms the basis of the controversy in the case into which she seeks to intervene, if the potential intervener has a “direct, substantial, [and] legally protectable” interest in the property or transaction that forms the basis of the controversy in the case into which she seeks to intervene.
Espy,
2.13 The disposition of the Waco Lawsuit could prevent the Institute’s ability to obtain the Identifying Information.
Thirdly, the potential intervener must be situated so that the disposition of the case into which she seeks to intervene may impair or impede her ability to protect her interest.
Ford,
If not allowed to intervene, the Institute would be prevented from ever being heard in a lawsuit that has the potential to end its quest to compel the USDA to disclose the Identifying Information. Moreover, that ruling could collaterally estop the Institute from re-litigating the Issue in the D.C. Court. Thus, the Waco Lawsuit has the potential to prevent the Institute from obtaining the Identifying Information without ever being heard. For these reasons, we conclude that the disposition of the Waco Lawsuit has the potential to impair the Institute’s interest.
Cf. Espy,
2.14 The USDA does not adequately represent the Institute’s interest.
The potential intervener has the burden of proving that the existing parties do not adequately represent her interest.
Espy,
The Institute contends that the public’s interest in the Identifying Information outweighs the potential invasion of privacy that could result if the USDA were to disclose it. The Institute argues that the USDA’s representation may be inadequate because the USDA, in the D.C. Lawsuit, took a position contrary to the Institute’s contention and the position it now takes. The Institute, further, argues that the USDA’s representation, thus far, has been inadequate because the USDA failed to contest the TRO or preliminary injunction *381 and object to the admission of questionable evidence. 8
The USDA is a governmental agency that must represent the broad public interest, not just the Institutes’s concerns.
See Espy,
3. Conclusion.
Applying Rule 24(a)’s four requirements we conclude that the Institute is entitled to intervene as a matter of right.. Their motion was timely and the Waco Court’s use of the date the Institute knew of the existence of the Waco Lawsuit as its starting point to determine timeliness was an abuse of discretion. The interest the Institute asserts is related to the transaction that forms the basis of the controversy in the Waco Lawsuit, the disclosure of the Identifying Information. Falling to allow the Institute to intervene could prevent the Institute from ever obtaining the Identifying Information. And the USDA, because of its presumably objective position, may inadequately represent the Institute’s interest. Therefore, we conclude that the Waco Court, in spite of its diligent and evenhanded effort to manage this difficult and complex case, erred in denying the Institute’s intervention of right. The order denying the intervention is Reversed and the Waco Court is to proceed in a manner consistent with this opinion.
Notes
. 5 U.S.C. § 552 (1998).
. Pursuant to 5 U.S.C. § 552b (c)(6), a governmental agency cannot disclose information of a personal nature which would constitute a clearly unwarranted invasion of personal privacy, unless the agency finds that the public interest requires disclosure. 5 U.S.C. § 552b (c)(6) (1999).
. With respect to the Institute’s motion to intervene, the August 8, 2000 order states in toto:
The Animal Protection Institute has filed a motion to intervene in this suit. However, the motion is untimely since API has known about the suit for some time. Additionally, API's interests can be adequately protected by the Government, which has taken a position in accordance with API’s ultimate goal-the release of identifying information regarding the participants in the LPC program. API’s arguments regarding the effects of the LPC’s and its role as an animal advocacy organization are irrelevant. Accordingly, the Animal Protection Institute's Motion to Intervene is DENIED.
. The Appellees characterize the substantive issue underlying the Waco Lawsuit as being “much broader,” e.g. "whether the disclosure of the [Identifying Information] ... would constitute an arbitrary and capricious exercise of the Government's authority and an unlawful abuse of agency discretion.” Appel-lees have mischaracterized the substantive issue underlying the Waco Lawsuit. The Ap-pellees' concerns are merely sub-issues of the larger question-does the public’s interest in the Identifying Information outweigh the potential invasion of privacy that could result if the USDA were to disclose it.
. Had the Waco Court granted the USDA’s motion to stay the Waco Lawsuit pending the D.C. Lawsuit, the Appellees, surely, would have argued to the D.C. Court that they be allowed to intervene in the D.C. Lawsuit and that their stake in that lawsuit did not materialize until the Waco Court stayed its lawsuit, the Waco Lawsuit. The Appellees, however, would possibly have unclean hands.
. 5 U.S.C. § 552(a)(4)(B) governs venue in suits brought under the Act. It provides in relevant part:
On complaint, the district court of the United States in the district in which the complainant resides, or has his principal place of business, or in which the agency records are situated, or in the District of Columbia, has jurisdiction to enjoin the agency from withholding agency records and to order the production of any agency records improperly withheld from the complainant. ...
5 U.S.C. § 552(a)(4)(B) (1999) (emphasis added).
. In their response to the USDA's motion to transfer venue, the Appellees expressly concede that the Institute should be allowed to intervene in the Waco Lawsuit. Specifically, the Appellees state: "If the animal rights group [, the Institute] wishes to be heard, they can intervene in this case-indeed, since both the group and its lawyers are based in Boulder, Colorado, Waco should be a more convenient forum for them than Washington, D.C.” (emphasis added).
. The Institute complains that the TJSDA "sat idle” while the Appellees offered evidence of "animal rights terrorism” that had nothing to do with the Institute or the Collar.
