Opinion for the Court filed by Circuit Judge RUTH BADER GINSBURG.
Plaintiffs-appellants seek to pursue claims that real estate advertisements placed by defendants-appellees featuring white models to the exclusion of black models violated the Fair Housing Act of 1968 *26 (FHA), 42 U.S.C. §§ 3601-31. The district court held the claims time-barred. We reverse that determination and remand for further proceedings.
The appeal involves consolidated actions against two unrelated sets of defendants. In the first action, commenced in October 1986, the co-defendants are Colonial Village, Inc. (Colonial), owner and manager of a residential condominium in Arlington, Virginia, and Mobil Land Development Corporation (MLDC); Colonial is wholly owned by MLDC which, in turn, is wholly owned by the Mobil Corрoration, a publicly-held corporation. In the second action, commenced in November 1986, the co-defendants are Marvin J. Gerstin and the advertising agency he is alleged to own and control, Marvin Gerstin Associates, Inc. Both sets of defendants are charged with running discriminatory ads regularly in The Washington Post from January 1985 through the spring of 1986.
Plaintiffs are Girardeau A. Spann, a black resident of the District of Columbia, the Fair Housing Council of Greater Washington, and the Metropolitan Washington Planning & Housing Association. Both organizational plaintiffs are non-profit corporations dedicated to ensuring equality of housing opportunity through education and other efforts. Requesting injunctive relief and damages, plaintiffs rely primarily on section 804(c) of the FHA, which declares it unlawful
[t]o make, print, or publish, or cause to be made, printed, or published any notice, statement, or advertisement, with respect to the sale or rental of a dwelling that indicates any preference, limitation, or discrimination based on race, color, religion, sex, or national origin, or an intention to make such preference, limitation, or discrimination.
42 U.S.C. § 3604(c). Plaintiffs additionally assert 42 U.S.C. §§ 1981, 1982 in support of their claims.
The procedural course of this litigation has not been smooth. We describe it summarily. After consolidating the two cases in January 1987, the district court scheduled briefing on dispositive motions. In May 1987, that court ruled for defendants 1) dismissing for failure to state a claim upon which relief can be granted plaintiffs’ pleаs under 42 U.S.C. §§ 1981, 1982, and 2) granting summary judgment striking out the FHA claims as time-barred.
Spann v. Colonial Village, Inc.,
Plaintiffs’ appeal from the district court’s May 1987 decision was aborted when Colonial moved in this court to dismiss for want of the requisite finality. Colonial pointed out that the district court had left unaddressed co-defendant MLDC’s objection that MLDC was neither properly served nor amenable to service in the District of Columbia. A motions panel of this court, in response to Colonial’s plea, dismissed the appeal “without prejudice for lack of a final order under Fed.R.Civ.P. 54(b) and 28 U.S.C. § 1291.” Spann v. Colonial Village, Inc., Nos. 87-7118 & 87-7119 (D.C.Cir. Apr. 6, 1988).
The district court then endeavored to “make[] the judgment in these cases final.” In an October 1988 decision, that court resolved two matters: (1) it denied MLDC’s motion to dismiss or quash service of process; and (2) it dismissed thе Gerstin defendants’ motion for sanctions under Fed.R.Civ.P. 11.
Spann v. Colonial Village, Inc.,
Plaintiffs once again appeal. We take up first the question of standing and explain why the organizational plaintiffs meet that threshold requirement. We next address the timeliness of the appeal, and the issue of personal jurisdiction over MLDC. Finally, we consider the vitality of the claims in suit, and hold that the FHA claims were not pursued too late.
*27 Standing
The initial issue in these cases is whether plaintiffs possess standing to invoke the jurisdiction of the federal courts. No “prudential standing” inquiry is in order, however, because Congress intended standing under the Fair Housing Act to extend to the full limits of Article III.
See Havens Realty Corp. v. Coleman,
The plaintiff organizations, the Metropolitan Washington Planning & Housing Association (MWPHA) and the Fair Housing Council of Greater Washington (FHC), assert standing to sue on their own behalf, and we turn now to those assertions. An organization has standing on its own behalf if it meets the same standing test that applies to individuals. The organization must show actual or threatened injury in fact that is fairly traceable to the alleged illegal action and likely to be redressed by a favorable court dеcision.
See Valley Forge Christian College v. Americans United for Separation of Church and State, Inc.,
Accordingly, just as an individual lacks standing to assert “ ‘generalized grievances’ about the conduct of Government,”
see Schlesinger v. Reservists to Stop the War,
That the аlleged harm affects the organization’s noneconomic interests — for example, its interest in encouraging open housing — “does not deprive the organization of standing.”
Id.
at 379 n. 20,
Plaintiff organizations have alleged such injuries here. We first summarize, and then elaborate on, the organizations' allegations. Both MWPHA and FHC have charged that defendants’ preferential advertising tended to steer black home buyers and renters away from the advertised complexes and thus impelled the organizations to devote resources to checking or neutralizing the ads’ adverse impact. The organizations also claimed that the advertisements required them to devote more time, effort, and money to endeavors designed to educate not only black home buyers and renters, but the D.C. area real estate industry and the public that racial preference in housing is indeed illegal.
Relating the organizations’ claim to standing in more detail, we begin with the statute. Section 804(c) of the Fair Housing Act prohibits any advertisement that “indicates any preference, limitation, or discrimination based on race, color, religion, sex, or national origin, or an intention to make any such preference, limitation, or discrimination.” 42 U.S.C. § 3604(c). Section 812(a) of the Act expressly provides a pri *28 vate right of action to enforce the rights created by Section 804. See id. § 3612(a).
Plaintiffs complained that the “repeated and continued depiction of white models and the complete absence of black models” in defendants’ advertisements “indicate a preference based on race” in violation of the statute. Colonial Complaint ¶ 12, Joint Appendix (J.A.) at 12; Gerstin Complaint ¶ 7, J.A. at 22. Plaintiffs crucially alleged that these advertising practices “interfered with plaintiff FHC and MWPHA’s efforts and programs intended to bring about equality of opportunity for minorities and others in housing” and required plaintiffs “to devote scarce resources to identify and counteract defendants’ advertising practices.” Colonial Complaint H 17, J.A. at 13; Gerstin Complaint ¶1 27, J.A. at 22.
In affidavits submitted to the district court, the executive directors of MWPHA and FHC further related how defendants’ advertisements concretely injured the organizations by depleting scarce resources, apart from generating expenditures in these enforcement actions. 1 The directors first charged that defendants’ white-only advertising “reinforces archаic stereotypes of segregation in housing” and "encourages discriminatory attitudes.” Declaration of Larry Weston, Executive Director MWPHA 119, J.A. at 118; Declaration of Patricia A. Horton, Executive Director FHC ¶ 11, J.A. at 126. MWPHA’s director then alleged that “[tjhis directly decreases the effectiveness of the MWPHA’s efforts to educate the real estate industry and the community” about laws prohibiting discrimination in housing and “necessitates increased educational efforts to counteract the influence of defendants’ discriminatory ads.” Declaration of Larry Weston ¶ 9, J.A. at 118. FHC’s director made similar allegations about the ads’ effects on FHC’s education programs.
Both organizations claimed that the advertising “impacts adversely” оn the organizations’ “real estate testing program by acting as a ‘steering’ method which discourages black home buyers and renters before they ever reach a particular complex, necessitating the [organizations] to broaden the scope of [their] efforts in order to reach all forms of discriminatory housing practices.” Declaration of Patricia A. Horton If 11, J.A. at 126-27; Declaration of Larry Weston II 9, J.A. at 118. MWPHA and FHC reiterated, in line with
Havens Realty,
that they have been “frustrated by defendants’ ... practices,” which have discouraged black home buyers and renters from considering defendants’ housing and required the organizations to expend additional resources to identify and dispel this discouragement.
See Havens,
The “drain[s] on the orgаnizations’] resources” alleged here appear no less palpable or specific than the injuries asserted by the organizational plaintiff in
Havens. See Havens,
MWPHA and FHC thus do not simply claim that they are psychically injured by witnessing noncompliance with the Fair Housing Act.
Cf. Center for Auto Safety v. NHTSA,
This adequately asserted depletion of resources is also, as the courts in
Havens
and
Saunders
found, fairly traceable to the alleged racially-preferential advertising and likely to be redressed by court-ordered declaratory relief. The Supreme Court has noted that “in many cases the standing question can be answered chiefly by comparing the allegations of the particular complaint to those made in prior standing cases.”
See Allen v. Wright,
Like the organization in
Havens,
MWPHA and FHC must ultimately prove at trial that the defendants’ illegal actions actually caused them to suffer the alleged injuries before they will be entitled to judicial relief.
See Havens,
To conclude this discussion of standing, we return to our starting line
(see supra
p. 27) to underscore the difference between this suit and one presenting only abstract concerns or complaints about government policy or conduct.
Cf. Reservists to Stop the War,
Plaintiffs here do not seek to compel government action, to involve the courts in a matter that could be resolved in the political branches, or simply “to vindicate their own value preferences through the judicial process.”
Sierra Club,
Enforcement by private attorneys general has become a feature of many modern legislative programs. Congress has recognized the usefulness and the courts have acknowledged the propriety of reliance on an individual or group actually injured, or threatened with injury, to vindicate the public interest.
See, e.g., Allen v. State Board of Elections,
Timeliness of Appeal
We turn next to the timeliness of this appeal. The Gerstin appellees say the appeal in the case against them is too late; MLDC, on the other hand, objects that appellants have come here too soon. We conclude that the ease is properly before us as to all appellees.
Far from appealing “seventeen months too late,”
see
Brief for Appellees Marvin Gerstin Associates, Inc. and Marvin Gerstin at 3, plaintiffs were unable to engage this court’s review at an earlier time. The district court’s May 1987 decision left issues open as to one of the defendants,
i.e.,
MLDC’s service of process/personal jurisdiction objections had not been addressed; the decision was thus unfinished, and therefore remained unripe for appellаte review.
See
Fed.R.Civ.P. 54(b);
Cablevision Systems Development Co. v. Motion Picture Ass’n,
Plaintiffs did attempt an appeal in June 1987, but Colonial Village blocked that move by successfully asserting, as grounds for dismissal, the final judgment rule. See Spann v. Colonial Village, Inc., Nos. 87-7118 & 87-7119 (D.C.Cir. Apr. 6, 1988) (order dismissing consolidated appeals “without prejudice for lack of a final order under Fed.R.CivJP. 54(b) and 28 U.S.C. § 1291”). At that time, the Gerstin defendants stood silently by. They never urged severance of the claims against them. First, they sought no Rule 54(b) certification from the district court when that court issued the May 1987 unfinished dеcision. Later, they proposed no deconsolidation in this court to salvage the plaintiffs’ June 1987 try for an earlier appeal. They have no tenable basis, therefore, for urging their exemption from the current appeal. In short, this appeal, taken within thirty days of the October 1988 disposition, see Fed.R.App.P. 4(a), is not too late.
Nor is the appeal premature, as MLDC contends it is. The district court expressly stated that its October 1988 Memorandum and Order resolving remaining issues “makes judgment in these cases final.”
Spann,
The purpose of the “separate document” requirement is explained in the Notes of Advisory Committee on Rules concerning the 1963 Amendment to Rule 58:
Hitherto some difficulty has arisen, chiefly where the court has written an opinion or memorandum containing some apparently directive or dispositive words, e.g., “the plaintiff’s motion [for summary judgment] is granted[.]” ... Clerks on occasion have viewed these opinions or memoranda as being in themselves a sufficient basis for entering judgment in the civil docket аs provided by Rule 79(a). However, where the opinion or memorandum has not contained all the elements of a judgment or where the judge has *32 later signed a formal judgment, it has become a matter of doubt whether the purported entry of judgment was effective, starting the time running ... for the purpose of appeal....
The amended rule eliminates these uncertainties by requiring that there be a judgment set out on a separate document — distinct from any opinion or memorandum — which provides the basis for the entry of judgment. That judgments shall be on separate documents is also indicated in Rule 79(b); ....
The separate-document requirement, although a salutary main rule, is not a “categorical imperative.”
See Bankers Trust Co. v. Mallis,
[i]f, by error, a separate judgment is not filed before a party appeals, nothing but delay would flow from requiring the court of appeals to dismiss the appeal. Upon dismissal, the district court would simply file and enter the separate judgment, from which a timely appeal would then be taken. Wheels would spin for no practical purpose.
Id. (footnote omitted).
Rule 58, we agree, “must be applied in such a way as to favor the right to appeal.”
Matter of Seiscom Delta, Inc.,
“[i]f an appellant files his notice of appeal from a final judgment within the prescribed time after the entry of the judgment as a separate document, his appeal cannot be defeated by the argument that his time to appeal began to run from the entry of some earlier decision, opinion, or order.”
Id.
at 284 (quoting
Hanson v. Town of Flower Mound,
In sum, the district court, in October 1988, took what was plainly meant to be its ultimately dispositive adjudicatory action, constituting its final decision in the case. That decision, we hold, qualifies as “final” for purposes of appellate review pursuant to 28 U.S.C. § 1291 (authorizing review of “final decisions” of district courts). While we are thus satisfied that the appeal is not premature, we emphasize that, to avoid dispute and promote certainty, it is the better practice for the district court to assure as a matter of course the entry of each judgment as a separate document. See id. at 284.
Personal Jurisdiction over MLDC
In an April 11, 1989 order, a motions panel of this court ruled that, because MLDC had not filed a cross-appeal, the court could not entertain MLDC's arguments regarding the absence of personal jurisdiction. That ruling, however, was made without benefit of a full display of the procedural situation in this case; we therefore deem the ruling “without prejudice to reexamination upon full briefing and argument” before the merits panel.
See Association of Investment Brokers v. SEC,
It is true that forum objections,
i.e.,
personal jurisdiction and venue, can be waived at any stage of a proceeding and ordinarily are waived by failure to take a
*33
cross-appeal.
See United States v. American Ry. Express Co.,
We conclude that the requisite exceptional circumstances are present here; accordingly, we will take up MLDC’s personal jurisdiction challenge. Just as we declined to apply Rule 58 mechanically to insist on a separate-judgment document as a prerequisite to plaintiffs’ appeal, so we decline to preclude MLDC from raising objections it plainly intended to preserve. The uncertainty generated by the absence of a judgment conforming to Rule 58’s separate-document requirement both explains and excuses MLDC’s failure to cross-appeal. Neither plaintiffs nor MLDC should be trapped by the confusion that existed over the timeliness of plaintiffs’ appeal.
MLDC complains that process was not properly served on it. More fundamentally, MLDC denies the existence of the minimum contacts with this forum and lawsuit necessary to justify, under due process, maintenance of the action against it.
But cf. Wells Fargo & Co. v. Wells Fargo Express Co.,
When this litigation returned to the district court following this court’s April 1988 dismissal of the June 1987 appeal for want of a final order, plaintiffs promptly moved for the entry of final judgment. The district court thereupon considered the two matters still open in the consolidated cases: the Gerstin defendants’ motion for Rule 11 sanctions against plaintiffs; and MLDC’s motion to dismiss on grounds of improper service and lack of the requisite presence in or contacts with the forum. The district court denied the Gerstin defendants’ motion for sanctions as baseless, and also denied MLDC’s motion. The district court concluded that plaintiffs’ several attempts to serve MLDC out-of-state by mail and personal delivery were unavailing; that court held, however, that the proper service made on MLDC’s co-defendant and wholly-owned subsidiary, Colonial Village, sufficed to draw in MLDC as well. The district court stated:
[MLDC] conducts business in this jurisdiction, in many ways, including through Colonial Village, whose employees expressly hold themselves out as agents of [MLDC]. They list the parent corporation on their business cards and advertise [MLDC’s] control оf the property.
Spann,
Plaintiffs-appellants, in the instant appeal, did not address MLDC’s contentions that it was never served properly and that, in any event, it lacks the requisite affiliation with the District. Instead, plaintiffs-appellants argued only that MLDC’s personal jurisdiction objections are precluded, an argument we have rejected. See supra pp. 32-33. Examining the record ourselves, however, we find (and MLDC concedes) that an officer of Colonial did indeed display a business card identifying Colonial Village, Inc. as “a Mobil company.” But that is all we find. If there is more to connect MLDC to this case and forum, e.g., advertisements for Colonial Village mentioning Colonial’s affiliation with MLDC, it has not been pointed out to us.
Because we are unable to review intelligently the personal jurisdiction questions (MLDC’s affiliation with the District, and the propriety of serving Colonial on MLDC’s behalf) on the basis of the thin materials at hand, we return the matter of the amenability of MLDC to suit here for further airing. Noting that the liaison between MLDC and Colonial Village bears not only on the nexus required for personal *34 jurisdiction and the sufficiency of service of process, but on the merits of the complaint against MLDC as well, we leave it to the district court to decide whether discovery concerning the character of Colonial’s advertising and affiliations with MLDC should precede a definitive ruling on personal jurisdiction over MLDC. 5
Fair Housing Act Claims
The district court dismissed plaintiffs’ FHA claims as time-barred; we reverse that ruling because it erred in its method of determining whether a violative act occurred within the prescribed period.
Currently, the Fair Housing Act has a standard, two-year statute of limitations:
An aggrieved person may commence a civil action in an appropriate United States district court or State court not later than 2 years after the occurrence or the termination of an alleged discriminatory housing practice ... to obtain appropriate relief with respect to such discriminatory housing practice....
42 U.S.C. § 3613(a)(1)(A) (1989). At the time these actions commenced, however, Congress prescribed: “A civil action shall be commenced within one hundred and eighty days after the alleged discriminatory practice oсcurred.” 42 U.S.C. § 3612(a) (1982). Where one discrete act of discrimination was at issue, the prescription was unproblematic: that act had to fall within 180 days of the filing of the court complaint. “Continuing violations,” on the other hand, were less readily fitted to the statute’s terms. Eventually, the Supreme Court confirmed lower court opinion that
where a plaintiff, pursuant to the Fair Housing Act, challenges not just one incident of conduct violative of the Act, but an unlawful practice that continues into the limitation period, the complaint is timely when it is filed within 180 days of the last asserted occurrence of that practice.
Havens,
The district court identified as the relevant time frames in this litigation April 1986 to October 1986 for the complaint against Colonial, and May 1986 to November 1986 for the complaint against the Ger-stin defendants. That court arrived at each of these two periods by counting back 180 days from the complaint filing.
See Spann,
But plaintiffs’ complaints are not centered on those periods. Instead, plaintiffs complain of periods in which both Colonial and the Gerstin defendants featured exclusively white models. In the case against Colonial, that period runs from January 1985 to April 1986, and in the case against the Gerstin defendants, the relevant time frame is January 1985 to May 1986. In each case, the last of the long stream of all white ads, plaintiffs allege, occurred within the 180-day zone, i.e., in April or May 1986; thus, under the “continuing violation”/“last asserted occurrence” theory that the Supreme Court has advanced, see supra p. 34, the plaintiffs claims are not time-barred. 9
Section 1981 and 1982 Claims
The provisions of 42 U.S.C. §§ 1981, 1982, the Supreme Court has restated, have a limited province and do not qualify as all-purpose antidiscrimination or comprehensive open housing laws; in particular, the High Court has said that section 1982 “does not prohibit [real estate] advertising or other [dwelling place sale or rental] representations that indicate discriminatory prеferences.”
Jones v. Alfred H. Mayer Co.,
Conclusion
For the reasons stated, we reverse the district court’s ruling that plaintiffs’ Fair Housing Act claims are time-barred and we return the case for further proceedings consistent with this opinion.
It is so ordered.
Notes
. This court and the district court may properly consider affidavits submitted by the parties, in addition to the complaint, to resolve the standing question. The courts may also permit plaintiffs to amend their complaints to make the necessary allegations.
See Warth v. Seldin,
. Because we conclude that the organizations have standing on their own behalf, we do not decide whether individual plaintiff Spann or the organizations as representatives of their members possess standing.
See Village of Arlington Heights v. Metropolitan Housing Dev. Corp.,
. We do not suggest that separation of powers concerns totally regress so long as (1) Congress, rather than the courts, declares who may sue, and (2) all parties are private rather than public actors. Even in the absence of encroachment by one branch on the domain of another, there may remain as a live issue the appropriate functions of each branch. While congressional intention to authorize an action between private parties thus may not suffice to meet Article III strictures, the will of the legislature "cannot be overlooked in determining whether [plaintiffs] have standing to sue.”
Havens,
. We recognize that a document labeled "Order" rather than "Judgment” may satisfy Rule 58 sufficiently to start the appeal clock running, if the order is succinctly to the point, and does not have the characteristics of an elaborative opinion.
See United States v. Perez,
. When plaintiffs moved in May 1988 for an order entering final judgment, they asked the district court 1) to deny MLDC’s motion to quash service as moot, if that was the court’s original intention, or 2) to deny the motion on its merits, or 3) "if the court determines that [MLDC’s] motion to quash service ... may not be denied on the present state of the record, then ... [to] permit[ ] discovery as to the issues raised by the motion but grant[ ] a certificate under Rule 54(b) permitting the appeal to proceed ... as to all other parties."
. We recognize that the alleged violations in
Havens
were different from those pressed here. In
Havens,
any one of the acts allegedly committed by the defendant (lying to a tester about the availability of housing) would constitute a violation of § 804(a) of the FHA. Here, by contrast, it is highly unlikely that a single ad containing only white models could alone violate § 804(c). However, in
McKenzie, supra,
we upheld a grant of summary judgment in favor of plaintiffs on their Title VII claim even though no single act of the defendant would likely have violated Title VII. We recognized there that plaintiffs’ Title VII claim "rested largely on sheer numbers,”
.Several months before instituting court actions, plaintiffs filed administrative complaints with the District of Columbia Office of Human Rights and the United States Department of Housing and Urban Development.
. In another case brought by the same plaintiffs, the district court said it had held in this case only "that if in real estate advertisements some photographs feature white models, some black models, and some of both, no violation of the [Fair Housing] Act occurs merely because the races are not represented proportionately to population, or because black models are not included in every display, unless an intention to discriminate is shown by extrinsic evidеnce.”
Spann v. The Carley Capital Group,
Nos. 87-1154 & 87-1155, slip op. at 7,
. The district court appeared to recognize in its second encounter with this case that its initial time-bar decision bore reexamination. Dismissing the Gerstin defendants’ motion for sanctions, the district court said:
[Defendants contend that their advertising during the 180 days prior to the filing of the complaint does not indicate a racial preference, and that the complaint is therefore without basis in fact. In fact, however, the complaint of racial preference in defendants’ ads is not limited to that time period. Only the last asserted occurrence of a practice of racial preference need be in that 180 day period. In its Opinion of May 22, 1987, the Court found that the last of defendants’ all-white ads was published within the 180-day limitations period beginning on May 24, 1986.
Spann,
