*644MOORE, J., delivered the opinion of the court, in which MARTIN, J., joined. RYAN, J. (pp. 651-53), delivered a separate dissenting opinion.
OPINION
MOORE, Circuit Judge.In this appeal, we conclude that Article I, section 2, clause 4 of the United States Constitution is mandatory, imposing upon a state executive the duty to issue a writ of election when one of her state’s seats in the United States House of Representatives (“House”) becomes vacant during a congressional term. Because Robert Taft, Governor of Ohio (“Governor Taft”), refused to issue a writ of election when one of Ohio’s seats in the House became vacant due to the expulsion of James A. Traficant, Jr. (“Traficant”) and more than five months remained before the next Congress would convene, we hold that Governor Taft violated Article I, section 2, clause 4 and denied the voters in Ohio’s Seventeenth Congressional District, including members of the American Civil Liberties Union (“ACLU”), their rights to vote and to equal representation in violation of the Fourteenth Amendment. Accordingly, we REVERSE the district court’s decision and REMAND so that the district court may award appropriate declaratory relief and attorney’s fees to the ACLU.
I. BACKGROUND
Traficant represented the Seventeenth Ohio Congressional District (“the District”) from January 1985 through July 24, 2002, during the 99th through 107th Congresses. On July 24, 2002, the House passed House Resolution 495, expelling Traficant from the House. Subsequently, Governor Taft publicly announced that he would not call a special election to fill the House vacancy left by Traficant’s expulsion. Governor Taft decided, after consulting with local elected officials, not to hold a special election, citing the cost of an election, the difficulty presented by redistricting that was to take effect for the regularly scheduled election in 2002,1 the small length of time an elected replacement could be expected to serve, and the uninterrupted continuation of constituent services by the Clerk of the House. The 107th Congress was scheduled to adjourn on October 3, 2002; however, it did not adjourn sine die until November 22, 2002. Tim Ryan was elected to the House by the “new” Seventeenth District at a general election held on November 5, 2002, but did not take office until January 3, 2003. Therefore, the “old” Seventeenth District was without representation in the House and had diminished constituent services from July 2002 until January 2003.
On August 5, 2002, the ACLU filed a verified complaint in the United States District Court for the Southern District of Ohio, asserting a § 1983 claim and pendent state-law claims against Governor Taft. The ACLU prayed for injunctive and declaratory relief, requiring Governor Taft to call a special election to fill the House vacancy in the District, and for reasonable attorney’s fees pursuant to 42 U.S.C. § 1988. On August 19, 2002, the district *645court issued oral and written orders denying injunctive relief. On August 26, 2002, the district court issued an opinion and order denying the ACLU’s motion for a temporary restraining order and a preliminary injunction and dismissing the case, thereby denying a permanent injunction as well. On August 23, 2002, the ACLU filed a motion in the Sixth Circuit requesting emergency injunctive relief pending appeal, which a panel of this court denied on September 4, 2002.
The district court had jurisdiction pursuant to 28 U.S.C. §§ 1331, 1343, and 1367. We have jurisdiction over the appeal pursuant to 28 U.S.C. § 1291.2
II. ANALYSIS
A. Standard of Review
We review a district court’s decision to deny a preliminary injunction for abuse of discretion. Blue Cross & Blue Shield Mut. v. Blue Cross & Blue Shield Ass’n, 110 F.3d 318, 322 (6th Cir.1997). We also review a district court’s decision to deny a permanent injunction for abuse of discretion, and in doing so, we review the district court’s factual findings for clear error and review the district court’s legal conclusions de novo. Sec’y of Labor v. 3Re.com, Inc., 317 F.3d 534, 537 (6th Cir.2003). Although the district court did not specifically rule on the ACLU’s request for declaratory relief, instead dismissing the case in toto after ruling on the ACLU’s motion for preliminary injunctive relief, we review a “district court’s exercise of discretion under the Declaratory Judgment Act, 28 U.S.C; § 2201(a), for abuse of discretion.” Scottsdale Ins. Co. v. Roumph, 211 F.3d 964, 967 (6th Cir.2000).
B. Standing and Mootness
Jurisdiction, including standing, is “ ‘assessed under the facts existing when the complaint is filed.’ ” Cleveland Branch, N.A.A.C.P. v. City of Parma, 263 F.3d 513, 524 (6th Cir.2001) (quoting Lujan v. Defenders of Wildlife, 504 U.S. 555, 570 n. 4, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992)), cert. denied, 535 U.S. 971, 122 S.Ct. 1438, 152 L.Ed.2d 382 (2002). In order to meet the standing requirements derived from Article III,
a plaintiff must show: “(1) it has suffered an ‘injury in fact’ that is (a) concrete and particularized and (b) actual or imminent, not conjectural or hypothetical; (2) the injury is fairly traceable to the challenged action of the defendant; and (3) it is likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision.”
Id. at 523-24 (quoting Friends of the Earth, Inc. v. Laidlaw Envtl. Servs., 528 U.S. 167, 180-81, 120 S.Ct. 693, 145 L.Ed.2d 610 (2000)).' To bring suit on behalf of its members, an association must show “ ‘its members would otherwise have standing to sue in their own right, the interests at stake are germane to the organization’s purpose, and neither the claim asserted nor the relief requested requires the participation of individual members in *646the lawsuit.’ ” Id. at 524, 120 S.Ct. 693 (quoting Friends of the Earth, Inc., 528 U.S. at 181, 120 S.Ct. 693, 145 L.Ed.2d 610).
The ACLU filed the complaint in this action “on behalf of its members who reside in and who are electors in the Seventeenth Ohio Congressional District.” J.A. at 6 (Comply 3). In this case, the ACLU has demonstrated that its members would have had “standing to sue in their own right.” Cleveland Branch, N.A.A.C.P., 263 F.3d at 524. The ACLU submitted affidavits from Louise Lefkort, Robert H. Sacherman, and Carol C. Sach-erman, who were all members of the ACLU, resided in the “old” Seventeenth District, were registered to vote in that district, and desired to vote in a special election to fill the House seat left vacant by the expulsion of Traficant. These members had suffered an actual injury, as they were without representation in the House and had been threatened with the imminent denial of their right to vote. This injury was fairly traceable to Governor Taft’s actions because Governor Taft announced that he was not going to issue a writ of election calling for a special election. This injury would have been re-dressable by injunctive and declaratory relief, in that an injunction requiring Governor Taft to issue a writ of election would have allowed residents of the district to exercise their right to vote and to regain representation in the House.
The ACLU has also shown that the interests at stake in this case are germane to the organization’s purpose. The ACLU submitted an affidavit from its Executive Director, Christine Link, explaining the organization’s purpose as follows: “The object of this organization is to aid in maintaining and extending constitutional and other fundamental rights, liberties, privileges, and immunities, and to take all legitimate actions in furtherance of that object without political partisanship.” J.A. at 161 (Link Aff.) (emphasis in original). This ease addresses citizens’ right to vote and right to equal representation, which falls squarely within the ACLU’s purpose of guaranteeing constitutional and fundamental rights. Finally, this action does not require the participation of individual members of the organization.
While standing is assessed at the outset of the litigation, a case may become moot during the course of litigation, depriving the court of jurisdiction. Cleveland Branch, N.A.A.C.P., 263 F.3d at 524-25. The doctrines of standing and mootness serve different purposes: “In essence, standing concerns only whether a plaintiff has a viable claim that a defendant’s unlawful conduct ‘was occurring at the time the complaint was filed’ while mootness addresses whether that plaintiff continues to have an interest in the outcome of the litigation.” Id. at 525 (citations omitted). These different purposes are reflected in well-established exceptions to the mootness doctrine, including the doctrine that a case will not become moot if the injury is capable of repetition, while evading review. Friends of the Earth, Inc., 528 U.S. at 190, 120 S.Ct. 693.
At this time, the 108th Congress has convened; therefore, we can no longer provide appropriate injunctive relief. We can, however, still award declaratory relief and attorney’s fees, provided the case has not become moot. Vacancies in the House can happen near the end of a congressional term, making it difficult for litigation to provide an effective remedy. See Jackson v. Ogilvie, 426 F.2d 1333, 1337 (7th Cir.) (noting, while treating an identical situation, that the case would not be mooted by the inappropriateness of an injunction, that plaintiffs would be entitled to declaratory *647judgment, and that cases “of this type in the election field are peculiarly ‘capable of repetition, yet evading review.’ ”) (quoting Moore v. Ogilvie, 394 U.S. 814, 816, 89 S.Ct. 1493, 23 L.Ed.2d 1 (1969)), cert. denied, 400 U.S. 833, 91 S.Ct. 66, 27 L.Ed.2d 64 (1970). In fact, since this case was filed, another House vacancy occurred in Ohio’s Third Congressional District due to the resignation of Tony Hall to take a position in the Bush administration. We conclude that the injury involved in this case is capable of repetition, while evading review, and thus is not moot.
C. Laches
We agree with the district court’s conclusion that the ACLU’s action is not barred by the doctrine of laches. Where a plaintiff seeks solely equitable relief, his action may be barred by the equitable defense of laches if (1) the plaintiff delayed unreasonably in asserting his rights and (2) the defendant was prejudiced by this delay. Brown-Graves Co. v. Central States, Southeast and Southwest Areas Pension Fund, 206 F.3d 680, 684 (6th Cir.2000). In this case, Governor Taft announced on July 25, 2002 that he was not going to call a special election to fill the vacancy in the District. The ACLU filed on August 5, 2002, eleven days later, its complaint, its motion for a temporary restraining order and preliminary injunction, and its supporting memorandum. It is true that in Kay v. Austin, 621 F.2d 809, 813 (6th Cir.1980), we held that a plaintiff seeking to be named on a presidential primary ballot was barred from obtaining injunctive relief because he delayed bringing suit until twenty-five days after he knew the choice of candidates had been made. In Kay, however, the defendant Secretary of State introduced evidence specifically demonstrating how this short delay had prejudiced the defendant, in that the Secretary provided evidence that most of the costs associated with the elections preparations had been expended during this delay. Id.
In this case, each day that passed may have made it more difficult to hold a special election; however, there is no evidence in the record indicating specifically how this short delay prejudiced Governor Taft. Likewise, there is no evidence that Governor Taft had expended money or made alternate preparations during the delay. We conclude that the passage of eleven days was not unreasonable delay. Moreover, we conclude that Governor Taft has not sufficiently demonstrated that he was prejudiced by this delay.
D. Article I, Section 2, Clause 4
Article I, section 2, clause 4 of the United States Constitution addresses the mechanism for filling vacancies in the House that occur during a congressional term, providing: “When vacancies happen in the Representation from any State, the Executive Authority thereof shall issue Writs of Elections to fill such Vacancies.” Article I, section 4, clause 1 gives primary control over the election of Senators and Representatives to the states, providing: “The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Place of chusing Senators.” Congress, in turn, has enacted 2 U.S.C. § 8, indicating that states have the authority to determine the time of elections, providing: “The time for holding elections in any State, District, or Territory for a Representative or Delegate to fill a vacancy, whether such vacancy is caused by a failure to elect at the time prescribed by law, or by the death, resignation, or incapacity of a person elected, may be prescribed by the laws of the *648several States and Territories respectively.” The district court concluded that the considerable discretion given to state government officials to determine election procedures, particularly the discretion to set a time for a special election to replace a Representative, applied to the decision of whether to hold such a special election at all. The ACLU argues that Article I, section 2, clause 4 is mandatory; therefore the government must call for a special election.
Given the infrequency of House vacancies, and the even greater infrequency of governors refusing to call special elections to fill them, only one case, Jackson v. Ogilvie, deals with such a situation. Jackson arose when the governor of Illinois refused to call a special election after the death of a Representative on August 13, 1969. 426 F.2d at 1334. Voters brought suit on December 16, 1969, and “the district court dismissed the action for want of jurisdiction” on March 16,1970, finding the rights asserted too insubstantial to support jurisdiction, as “the relatively short period in which the Sixth District will remain unrepresented” was not enough to raise constitutional questions. Id. at 1334-35. The Seventh Circuit reversed in an opinion issued on May 6, 1970, concluding that the district court had erred by dismissing the action due to the limited time that a Representative would serve, stating, “Except in those instances [where the period of possible service could truly be deemed de minimis] the delegation to the state legislature of this power over procedure does not, in our opinion, alter the character of the Governor’s duty to issue a writ of election.” Id. at 1336. In so holding, the court found that a special election could still be held on November 3,1970, the date of the next general election, and concluded that it was “not prepared to say as a matter of law that representation from the time the results of the November 3 election will be determined to January 3, 1971 is de minimis.” Id. at 1337.
In comparing Jackson to the instant case, both parties agree that the time periods involved are important; they merely disagree on which time periods are important. Under Illinois law at that time, 162 days had to elapse between the issuance of the writ of election and the election itself. Id. at 1335. The Seventh Circuit held that the governor had a duty to issue a writ at the time of the Representative’s death, which would have allowed an election to be held on January 23, 1970, with eleven months left on the term. Id. at 1337. When the district court dismissed the case, an election could have been held on August 25, 1970, with four months left on the term. Finally, the Seventh Circuit refused to hold as a matter of law that the amount of time between the certification of an election held on the next general election date, November 3, 1970, and the beginning of the next term, on January 3, 1971, is de minimis. The ACLU emphasizes Jackson’s indication that the time of possible service in the House in this case, November 5, 2002 to January 3, 2003, was not de minimis. Conversely, Governor Taft emphasizes that Jackson only conclusively held that an enforceable duty existed when eleven months remained on the term at the time the vacancy occurred.
The parties and the district court cite three other cases that influence our decision in this case. In Valenti v. Rockefeller, 292 F.Supp. 851, 853 (W.D.N.Y. & S.D.N.Y.1968) (three-judge district court), aff'd mem., 393 U.S. 405, 89 S.Ct. 689, 21 L.Ed.2d 635 (1969), a U.S. Senate vacancy occurred in June 1968 upon the assassination of Senator Robert F. Kennedy, and state statutory law mandated that the vacancy would be filled in November 1970, as sixty days were required prior to the primary election, and replacement Senate *649elections were to be held in even-numbered years. The plaintiffs in Valenti argued that the operation of state law unconstitutionally denied them their rights to vote and to representation. Id. The district court determined that the delay was constitutional when balanced against the state interests of voter turnout and interest; of preserving local elections from “the more party-oriented political currents generated by statewide or national contests”; and of avoiding the economic hardship on Senate candidates of financing a campaign in the off-year.3 Id. at 854, 859. In Mason v. Casey, No. 91-5728, 1991 WL 185243, at *1-2 (E.D.Pa. Sept.18, 1991), a House vacancy occurred on September 11, 1991, and state statutory law mandated that the special election would be held at least sixty days after the governor issued a writ of election. Like in Valenti, the plaintiffs argued that the operation of state law created an unconstitutional delay beyond the plaintiffs’ proposed date of November 5, 1991, and the district court held the delay which likely was five additional months to be constitutional. Id. at *2-3. Finally, in State ex rel. Armstrong v. Davey, 130 Ohio St. 160, 198 N.E. 180, 181 (1935), the Ohio Supreme Court ratified the governor’s decision to set a replacement date at a later date than the plaintiff felt was proper.
Like the Seventh Circuit, we conclude that Article' I, section 2, clause 4 is mandatory, requiring the state’s executive to issue a writ to fill a vacancy in the House.4 We recognize that there may be instances where the time remaining in the congressional term is truly de minimis, thereby excusing the executive from issuing the writ, but the time involved in this case cannot be considered de minimis.5
We also recognize that Article I, section 4, clause 1 gives states the dis*650cretion to determine the “Times, Places, and Manner” ;of holding such elections, and that the states have valid interests in ensuring fair and reliable elections. As Valenti and Mason indicate, legislative balancing between a state’s interests in ensuring fair and reliable elections, and its citizens’ rights to vote and to equal representation, is entitled to considerable deference. Ohio has exercised its discretion to determine the time, place, and manner of elections by enacting a comprehensive election code. Governor Taft complains of the expense, inconvenience, . and possible inaccuracies that would have accompanied a special election held on November 5, 2002. We point out that the Ohio legislature, through its election code, has determined the length of time it considers necessary for conducting such a special election. If the Ohio legislature determines that more time is needed to hold such an election, it may amend its election code, and should a need to review such provisions arise, we will accord them appropriate deference.
Had Ohio’s election code imposed requirements that made- a special election an impossibility in this' case, the ACLU would have been faced with the burden of proving those enacted requirements were unconstitutional. As Governor Taft concedes, however, it would have been possible to hold a special election that complied with the requirements imposed by the legislature in the election code to fill the vacancy in the Seventeenth District.6
In summation, we conclude that Article I, section 2, clause 4 imposed a mandatory duty upon Governor Taft to hold a special election to fill the vacancy in the District created by the expulsion of Traficant. Although there may be situations where an executive’s duty is excused because the time remaining on the Congressional term is truly de minimis, this was not such a situation. While legislative balancing of the state’s and its voters’ interests is entitled to deference, a special election that complied with Ohio’s election code could have been held in this case. Therefore, we hold that Governor Taft violated his duty to call a special election under Article I, section 2, clause 4 and denied ACLU members the rights to vote and to equal protection in violation of the Fourteenth Amendment. These constitutional violations entitle the ACLU to declaratory relief pursuant to 42 U.S.C. § 1983 and 28 U.S.C. § 2201 and to reasonable attorney’s fees pursuant to 42 U.S.C. § 1988.
III. CONCLUSION
We conclude that the district court committed errors of law, and thus abused its discretion by failing to award the ACLU appropriate equitable and declaratory re*651lief. Accordingly, we REVERSE the district court’s decision and REMAND this case so the district court may award appropriate declaratory relief and attorney’s fees to the ACLU.
. We note that the ACLU filed its notice of appeal on August 19, 2002, specifying that the ACLU was appealing the district court's August 19, 2002 order denying “preliminary and permanent injunctive relief and entering judgment for the Defendant.” Joint Appendix ("J.A.”) at 169. The district court's August 19 written order, however, only denies the ACLU’s motion for a temporary restraining order. In its August 19 oral ruling, the district court denied from the bench all in-junctive relief, "be it a temporary restraining order and a preliminary injunction or a permanent injunction.” J.A. at 228. A final written judgment in the case was' entered on August 27, 2002. Therefore, we have jurisdiction over the appeal pursuant to Fed. R.App. P. 4(a)(2). See Metro. Life Ins. Co. v. Marsh, 119 F.3d 415, 418 n. 3 (6th Cir.1997).
. The probativeness of Valenti v. Rockefeller, 292 F.Supp. 851, 853 (W.D.N.Y. & S.D.N.Y.1968), is substantially diminished by the fact that it addressed a vacancy in the Senate. The United States Constitution allows Senate vacancies to be filled by the governor through a temporary appointment, and thus the seat may be filled during the period between the vacancy and the special election. U.S. Const, amend. XVII; Valenti, 292 F.Supp. at 855. Moreover, if one of a state’s seats in the Senate becomes vacant, that state will still be represented in the Senate, whereas if one of a state's seats in the House becomes vacant, residents of that district will not be represented in the House. Valenti, 292 F.Supp. at 863.
. We are not at all persuaded by the Supreme Court of Rhode Island’s statement in In re the Representation Vacancy, 15 R.I. 621, 624, 9 A. 222 (R.I. 1887), that the governor, having the power under Article I, section 2, clause 4 of the United States Constitution, to issue a writ of election, also has the discretion to decide, considering the 49th Congress’s adjournment date, whether to exercise that power. This statement is dicta and the decision is an advisory opinion, not binding on this court. Nor are we persuaded by similar non-binding dicta in People ex rel. Fitzgerald v. Voorhis, 222 N.Y. 494, 119 N.E. 106, 108 (1918).
. The district court relied on the 107th Congress’s scheduled adjournment date of October 3, 2002 in concluding that the ACLU had not met its burden of demonstrating irreparable harm, as the parties contemplated holding a November 5, 2002 election and there was no way of knowing whether a hold-over session would occur, and thus whether the Seventeenth District would be unrepresented in a House vote. We conclude the scheduled adjournment date should not be used in evaluating whether a special election may be held in compliance with state law and whether the time remaining after such an election would truly be de minimis. As history shows, the House rarely adjourns sine die on its schedule adjournment date, and important legislation has been passed after such date. In fact, the amicus brief filed by Representative Marcy Kaptur notes that the 107th Congress passed several pieces of important legislation after its scheduled adjournment date of October 3, 2002, including the Iraq war resolution (October 10) and the creation of the Department of Homeland Security (November 13).
. To the extent that the Ohio election code purports to give unfettered discretion to Governor Taft regarding the time for calling the special election, it is not a meaningful standard entitled to deference. The Ohio code provides:
When a vacancy in the office of representative to congress occurs, the governor, upon satisfactory information thereof, shall issue a writ of election directing that a special election be held to fill such vacancy in the territory entitled to fill it on a day specified in the writ. Ohio Rev.Code Ann. § 3521.03. Moreover, the Ohio Supreme Court has interpreted an earlier, similar version of this provision as granting the governor discretion to decide when to call a special election, but not to decide whether to call an election. State ex. rel. Armstrong v. Davey, 130 Ohio St. 160, 198 N.E. 180, 181 (1935). While the Eleventh Amendment prevents us from compelling Governor Taft to comply with state law, we may consider Governor Taft's failure to act consistently with Ohio law when determining how much deference to accord his decision under the Constitution's delegation of election procedures to the states.
