A. J. Korioth is a United States citizen from Texas, a taxpayer, and a state legislator. He brought this action to challenge, as violative of the Federal and Texas constitutions, the establishment of regional planning agencies under a Texas statutory scheme. The City of Farmers Branch (the City) is a municipality which has participated in one of the regional planning agencies established under that scheme. The City sought to intervene as an additional plaintiff in Korioth’s suit. The district court dismissed the action of Korioth for lack of standing and denied the City’s motion to intervene. We agree that Korioth “al *1274 leged no injuries sufficient to give rise to a ‘case or controversy’,” and we find no clear abuse of discretion in the denial of the City’s motion to intervene. We affirm the order.
I. STANDING
Plaintiff-appellant Korioth alleged in his complaint to the district court that Tex.'Rev.Civ.Stat.Ann. art. 1011m (Supp. 1974), in providing a means for formal cooperation between certain state regional planning agencies and the Republic of Mexico, 1 contravened the United States Constitution’s proscription against states entering into treaties with foreign governments. 2 Korioth also alleged that the scheme violated the Texas constitution’s implicit mandate that sub-units of government may embrace no more than one county. 3 In his later filed “Memorandum of Authorities in Opposition to Defendant’s Motion to Dismiss,” Korioth added the claim that federal monies funding the regional agencies were being illegally spent, since the federal program only authorized payments to agencies empowered under state or local law to perform such planning. 4 In this appeal from the district court’s dismissal for lack of standing, Korioth argues that he has standing to litigate based on each of his statuses as a citizen, as a taxpayer, and as a legislator.
A. Citizen Korioth
The requirement that an individual have standing to litigate in federal courts is in part a derivative of the Constitution’s limitation of the federal judicial power to “cases” and “controversies,” U.S.Const. art. Ill, § 2, and in part the result of long favored prudential considerations. 5 Federal courts are not *1275 to render advisory opinions, but rather are to decide specific issues for parties with real disputes. 6 Cases are to be decided on the narrowest legal grounds available, 7 and relief is to be tailored carefully to the nature of the dispute before the court. 8
Although the Supreme Court has warned that generalizations about the law of standing are of dubious worth, 9 the currency of Baker v. Carr’s often quoted formulation of the general question to be considered seems not to have been devalued:
Have the appellants alleged such a personal stake in the outcome of the controversy as to assure that concrete adverseness which sharpens the presentation of issues upon which the Court so largely depends for illumination of difficult constitutional questions? This is the gist of the question of standing.
Recent decisions have indicated that in answering this question, a court’s focus should be on whether the complaining party has alleged any “injury in fact” which distinguishes that party, in relation to the alleged violations, from the undifferentiated mass of the public. 10 The requirement that a complaining party allege a specific injury in fact appears to be necessary so that all of the above discussed policy objectives may be furthered — although an irate citizen might vigorously pursue litigation challenging alleged governmental illegalities, a court cannot fashion a specific remedy without some finding of specific harm. The specific, distinct injury may be small, 11 but some such injury must be alleged for the litigant to have standing.
Prior to 1974, there were some indications of the development of a doctrine whereby requirements for citizen standing in “public actions” would be quite minimal.

cialized injury were held to have standing to bring a constitutional challenge against Congressmen’s membership in the Armed Forces Reserves in

D.D.C.1971,
It is tautologically clear that a citizen who asserts only his citizen status as a basis for standing to pursue constitutional or statutory claims has not specified any injury which sets him apart from the mass of citizens who desire that the state adhere to the legal amenities of governance. If Korioth has standing, then, it must be based either on his status as a taxpayer or that as a legislator.
B. Taxpayer Korioth
The Supreme Court case which now marks the limit in allowing taxpayers
qua
taxpayers standing to litigate a general constitutional claim is
Flast v. Cohen,
1968,
First, the taxpayer must establish a logical link between that status and the type of legislative enactment attacked. Thus, a taxpayer will be proper party to allege the unconstitutionality only of exercises of congressional power under the taxing and spending *1277 clause of Art. I, § 8 of the Constitution. It will not be sufficient to allege an incidental expenditure of tax funds in the administration of an essentially regulatory statute. . . . Secondly, the taxpayer must establish a nexus between that status and the precise nature of the constitutional infringement alleged. Under this requirement, the taxpayer must show that the challenged enactment exceeds specific constitutional limitations imposed upon the exercise of the congressional taxing and spending power and not simply that the enactment is generally beyond the powers delegated to Congress by Art. I, § 8. .

Korioth objects to the use of local, state, and federal funds derived from his taxes in the administration of the Texas regional planning agency scheme, and urges that Flast’s two-part test supports his standing. He trips and falls, however, on the respective qualifications which Flast adds to each part of its test. Korioth is basically challenging an “incidental expenditure of tax funds in the administration of an essentially regulatory statute” and, by analogy to the federal situation in Flast, alleges “simply that the enactment is generally beyond powers delegated to” the state legislature rather than showing that “the challenged enactment exceeds specific constitutional limitations imposed upon the exercise of the” legislature’s taxing and spending power. 16
That the rationale under which taxpayers were granted standing in
Flast
is an extremely limited one has become apparent with the Supreme Court’s decisions in
United States v.
Richardson,
17
and in
Schlesinger, supra,
C. Legislator Korioth
Having found the proffered legs of citizen and taxpayer standing to be infirm, we turn to Korioth’s assertion that the crutch of his special status as a state legislator can support this action. Several decided cases have held that in certain circumstances a legislator, in that capacity, may have standing to challenge official actions. 18 Generally, these cases *1278 have focused on allegations that the challenged action undermined the effectiveness of the exercise of a specific power of the legislator. 19 Another basis for legislator standing has been found in the duty of the legislature to investigate the acts of the executive in relation to possible impeachment, 20 although this basis for standing has been criticized. 21 Whatever the validity of these bases for legislator standing, they do not apply to Korioth — he cannot allege that the effectiveness of his vote, or of any other legislative power he may have, has been impeded by the vote of a majority of the legislature to enact the regional planning scheme, nor by the action of the state executive in implementing it. No question of possible impeachment has been raised.
None of the cases has indicated that a legislator, simply by virtue of that status, has some special right to invoke judicial consideration of the validity of a statute passed over his objecting vote. 22 We refuse to go that far here. In the circumstances of this case, the plaintiff’s seat in the legislature confers no standing.
II. INTERVENTION
In the order dismissing Korioth’s complaint for lack of standing, the trial court also denied without comment the motion of the, City of Farmers Branch to intervene, j The City here urges this denial was in 'érror, since it had alleged in its motion that the factors which render permissive intervention appropriate under Federal Rule of Civil Procedure 24(b) were present. 23 The question on appeal, however, is not whether those factors were present, but whether the trial court committed a clear abuse of discretion in denying the motion. 24 !
*1279 The court below may have been influenced in its denial of the City’s motion by its conclusion that the main plaintiff had no legally cognizable legs for standing. We cannot say that it was clearly unreasonable for the lower court To prefer not to create a commensalist for a non-existent host. Even if by osmotic transmutation, or some other jurisprudential phenomenon the intervenor might have been allowed to pursue alone the cause of action, j the judge committed no gross error in rejecting that evolution of the case, especially when no barrier appeared to preclude the City from_ bringing a new action in its own name. 25 The denial of the motion to intervene is" affirmed. 26
Finally, we emphasize that our diagnosis on Korioth’s lack of standing and our inability to find clear abuse of discretion in the denial of the City’s motion to intervene reflect no opinion on the merits of the constitutional and statutory issues underlying this case, nor on the standing of the City to pursue its own action. 27
Affirmed.
Notes
. Section 8 of art. 1011m provides:
With advance approval of the governor, a Commission in a region or area contiguous to areas in the Republic of Mexico may expend the funds available under the provisions of Section 6 of this Act in cooperation with agencies of the Republic of Mexico or its constituent states or local governments for planning studies encompassing areas lying both in this state and in contiguous territory of the Republic of Mexico.
. The Constitution provides that “no state shall enter into any Treaty, Alliance or Confederation,” art. I, § 10, cl. 1, and that the President “shall have power by and with the Advise and Consent of the Senate, to make Treaties provided two-thirds of the Senators present concur,” art. II, § 2, cl. 2. Korioth argues that art. 1011m, § 8, in purporting to bestow treaty-making power on the governor, is facially inconsistent with these provisions of the federal Constitution. The state has noted in response that no agreements with Mexico have as yet been entered into under the statute. Our disposition of the case on lack of standing pretermits any consideration of these constitutional conundrums.
. See 40 U.S.C. § 461(i)(6). Appellant’s assertion here is that since art. 1011m is in violation of the state constitution, see note 2, supra, the regional planning agencies cannot be said to be empowered under state law to perform planning. Thus, the argument goes, federal funding for the Texas Regional Commissions is in violation of the federal authorizing statute.

The “injury in fact” requirement means that a demonstration of “adverseness” alone is not enough to confer standing — no matter how sincere the plaintiffs motives in pursuing the litigation, there is no standing unless the dispute is made “concrete” by the allegation of specific harm.

When an appellant has other adequate irteans of ■ asserting its rights, a charge of abuse of discretion in the denial of a motion for permissive intervention would appear to be almost untenable on its face. See Levin v.
Ruby Trading Corp., 2
Cir. 1964,
. A line of old authorities, including Supreme Court cases, indicates that the proper disposition of an appeal from a denial of a motion for permissive intervention in which no abuse of discretion is shown is a dismissal, since no appealable final order has been entered.
See Allen Calculators,
note 24
supra.
As commentators have persuasively argued, however, a much better practice would be simply to regard any denial of a motion to intervene as a final order, and, when the intervention sought is permissive and no abuse of discretion is shown, to affirm the denial.
See, e. g.,
7A C. Wright & A. Miller,
supra
note 24, § 1923 at 626-32; 3B J. Moore, Federal Practice ¶ 24.15 (1974). This view has been reflected in a few recent cases.
See, e. g., Levin v. Ruby Trading Corp., 2
Cir. 1964,
. Korioth argues that if we find that he does not have standing to pursue this litigation, no one would have standing to pursue it. Even if this were true, the Supreme Court has stated that this is not a reason for finding that a party who can show no concrete injury has standing.
