OPINION
PHILLIPS, Chief Justice.
We have previously held in this case that the state public school finance system violates *493 article VII, section 1 of the Texas Constitution. 777 S.W.2d 391 ("Edgewood I"). Now we decide whether this violation remains following enactment of Senate Bill 1 by the 71st Legislature.[1] We hold that it does.

I
This action commenced in May 1984 when numerous school districts and individuals sought a judicial declaration that the state public school finance system was unconstitutional. After trial on the merits in 1987, the district court found that the system violated the Texas Constitution in several respects and enjoined the State from funding it after September 1, 1989, unless the Legislature repaired the constitutional defects by that date. The court of appeals reversed the district court's judgment in December 1988. 761 S.W.2d 859. On October 2, 1989, this Court in Edgewood I reversed the judgment of the court of appeals and reinstated the injunction issued by the district court, but postponed its effect until May 1, 1990. On that date, state funding of public schools was to cease unless the Legislature conformed the system to the requirements of the Constitution. 777 S.W.2d 391.
The district court extended the May 1 deadline[2] to allow the Legislature to complete its work on what became Senate Bill 1, which the Governor signed into law June 7, 1990.[3] Once Senate Bill 1 became law, plaintiffs returned to the district court seeking both a declaration that the system remained unconstitutional and an order enforcing the injunction affirmed by this Court in Edgewood I. After a lengthy hearing, the district court found that despite the changes in Senate Bill 1, the school finance system remained unconstitutional. Nevertheless, the district court vacated our injunction and denied any other injunctive relief or enforcement of this Court's mandate. The district court stated in its judgment that it would not entertain requests for further relief until it became apparent that the Legislature would not adopt a constitutional school funding system to be implemented beginning September 1, 1991.
Plaintiffs now seek relief from this judgment, arguing in substance that the district court exceeded its authority by vacating this Court's injunction and postponing consideration of further injunctive relief. Defendant state officials also complain by cross-appeal that the district court erred in finding that the school finance system continues to violate the Constitution after enactment of Senate Bill 1. Defendant-intervenor school districts challenge the Court's jurisdiction to consider any of these contentions.[4]

II
At the outset we must determine whether our jurisdiction has been properly invoked. Plaintiffs, plaintiff-intervenors and defendant state officials all assert that they are entitled to appeal the district *494 court's judgment directly to this Court, based upon article V, section 3-b of the Constitution[5] and section 22.001(c) of the Government Code.[6] Defendant-intervenors counter that the district court's judgment is not one from which a direct appeal is authorized by these constitutional and statutory provisions. We need not pass on these contentions because we conclude that the parties are properly before us for other reasons.
By our judgment in Edgewood I, the injunction originally issued by the district court and affirmed as modified by this Court became an order of both this Court and the district court. See State v. Walker, 679 S.W.2d 484, 485 (Tex.1984); City of Tyler v. St. Louis Southwestern Ry., 405 S.W.2d 330, 332 (Tex.1966). As the district court recognized, it was obliged to observe and enforce our judgment as rendered in the absence of changed conditions. Id. It is not for us to ascertain in the first instance whether conditions have changed since Edgewood I; that determination must be made by the district court, which can hear evidence, subpoena witnesses and make findings. Id. The district court's decision is reviewable on appeal. Id. However, we also have the power to enforce our mandate by mandamus if we can determine, without resolving factual disputes, that conditions have not changed and that the district court abused its discretion. See Walker, 679 S.W.2d at 485; see also Texas Aeronautics Comm `n v. Betts, 469 S.W.2d 394, 399 (Tex.1971); Conley v. Anderson, 164 S.W. 985, 986 (Tex.1913); Wells v. Littlefield, 62 Tex. 29, 30-31 (1884). As we said in City of Tyler: "in the absence of changed conditions it is the duty of the trial court to enforce the judgment [of this Court] as entered; and, if necessary, this Court can compel its enforcement." 405 S.W.2d at 332.
The district court concluded as a matter of law that Senate Bill 1 does not change the school finance system condemned in Edgewood I, and thus that the Legislature had not met its constitutional obligations. In this regard, the district court found no change in conditions since Edgewood I. The district court vacated our injunction, however, on the equitable grounds of deference to the Legislature and avoidance of disruption to public education. These equitable considerations are not changed conditions. They have been present throughout this litigation, and this Court was fully mindful of them in Edgewood I. Only this Court, not the courts below, may decide that for policy reasons our mandate should be modified or vacated. Conley, 164 S.W. at 986.
Plaintiffs request this Court to enforce its mandate. We have not only the power but the duty to enforce our mandate upon the request of a party if we determine that the district court acted improperly. See Wells, 62 Tex. at 30-31. We therefore treat this proceeding as being in the nature of an original mandamus proceeding to direct the district court to reinstate our injunction. If as a matter of law the district court was correct in its determination that the constitutional violation in the school finance system which we found in Edgewood I continues, then it clearly abused its discretion in vacating our injunction. Accordingly, we consider whether the school finance system remains unconstitutional following Senate Bill 1.

III
Senate Bill 1 does make certain improvements in public school finance. It attempts to realize the long-articulated objective *495 of assuring school districts substantially similar educational revenue for similar levels of local tax effort[7] by providing for a wide array of biennial studies to detect deviations from fiscal neutrality and inform senior policy makers when increased state funding is required.[8] These policy makers then recommend to the Legislature the amount of funds that should be allocated for public education for the succeeding biennium. Thus, for the first time, the system contains a mandate for biennial adjustment, based upon information from a battery of studies, with the intention of preventing the opportunity gap between poor and rich districts from re-widening each time legislative action narrows it.
However, Senate Bill 1 leaves essentially intact the same funding system with the same deficiencies we reviewed in Edgewood I. Senate Bill 1 maintains the basic two-tiered education finance structure known as the Foundation School Program. The first tier is a basic allotment designed to enable all districts to provide a basic education to all pupils. Each district that taxes itself at or above a minimum level is guaranteed a certain base level of funding, composed of state and local revenue, per weighted student in average daily attendance.[9] The second tier is the guaranteed yield or equalized enrichment tier, which is designed to equalize the ability of school districts to raise revenue to supplement their basic allotment. At this tier, all districts receive a guaranteed revenue per weighted student for each cent of local tax effort above the tier one minimum level. The State funds the difference between the guaranteed revenue and the amount each cent of local tax effort generates. If a district is so wealthy that each cent of tax effort generates more than the guaranteed revenue per weighted student, it receives no tier two revenue from the State.[10] To maximize their entitlement to state funding under tiers one and two, Senate Bill 1 contains incentives for most school districts to set their effective local tax rates at or above a state-designated minimum level.[11]
The State asserts that as districts respond to these incentives and as it shifts more of its funds to lower wealth districts, Senate Bill 1 will achieve substantial equity among the districts that educate 95% of our students. The State maintains that excluding the districts with the wealthiest 5% of the students is reasonable and within the Edgewood I requirement of "substantially equal access to similar revenues per pupil at similar levels of tax effort." 777 S.W.2d at 397. It argues that the annual cost of equalizing all districts to the revenue levels attainable by the richest districts would be approximately four times the annual cost *496 of operating the entire state government. Even if the incentives in the new law do not produce the anticipated results, the State contends that the newly mandated studies will lead to increased state funding, which will in turn produce equity. Plaintiffs complain of both the manner in which the State has attempted to achieve fiscal neutrality and the State's decision to exclude the wealthiest districts from the equalization formula.
We need not address the conflicting prognostications of the parties about whether Senate Bill 1 can or will be implemented to achieve efficiency among 95% of students. Although the parties presented much evidence about what may or may not happen in the future, the issue before us is whether present conditions have changed in such a way that the injunction ordered by this Court should not be enforced. The only material changes in the system since Edgewood I are those made by Senate Bill 1. The question we address is whether there is any evidence that those changes remove the constitutional violation.
In analyzing the constitutionality of the system after Senate Bill 1, we begin with the following conclusion in Edgewood I, grounded on the Texas Constitution:
The legislature's recent efforts have focused primarily on increasing the state's contributions. More money allocated under the present system would reduce some of the existing disparities between districts but would at best only postpone the reform that is necessary to make the system efficient. A Band-Aid will not suffice; the system itself must be changed.
777 S.W.2d at 397. Even if the approach of Senate Bill 1 produces a more equitable utilization of state educational dollars, it does not remedy the major causes of the wide opportunity gaps between rich and poor districts. It does not change the boundaries of any of the current 1052 school districts, the wealthiest of which continues to draw funds from a tax base roughly 450 times greater per weighted pupil than the poorest district. It does not change the basic funding allocation, with approximately half of all education funds coming from local property taxes rather than state revenue. And it makes no attempt to equalize access to funds among all districts. By limiting the funding formula to districts in which 95% of the students attend school, the Legislature excluded 132 districts which educate approximately 170,000 students and harbor about 15% of the property wealth in the state. A third of our students attend school in the poorest districts which also have about 15% of the property wealth in the state. Consequently, after Senate Bill 1, the 170,000 students in the wealthiest districts are still supported by local revenues drawn from the same tax base as the 1,000,000 students in the poorest districts.
These factors compel the conclusion as a matter of law that the State has made an unconstitutionally inefficient use of its resources. The fundamental flaw of Senate Bill 1 lies not in any particular provisions but in its overall failure to restructure the system. Most property owners must bear a heavier tax burden to provide a less expensive education for students in their districts, while property owners in a few districts bear a much lighter burden to provide more funds for their students.[12] Thus, Senate Bill 1 fails to provide "a direct and close correlation between a district's tax effort and the educational resources available to it." 777 S.W.2d at 397.
To be efficient, a funding system that is so dependent on local ad valorem property taxes must draw revenue from all property at a substantially similar rate. The present system does not do so. For example, if the Glen Rose ISD in Somerville County maitained *497 its 1989-90 tax rate of 25.3 cents per one hundred dollars of valuation, it would generate over $9500 this year for each of its 1170 students. If the property within Glen Rose were taxed at the same 91 cent rate that districts must impose this year under Senate Bill 1 to maximize the funding they receive from the State, that property would generate an additional $28 million. Similarly, if the property within Highland Park ISD in Dallas County were taxed at that level, it would generate an additional $18 million this year. The property within Iraan-Sheffield ISD in Pecos County would generate an extra $14 million. These examples illustrate the degree to which the current system insulates concentrated areas of property wealth from being taxed to support the public schools. The result is that substantial revenue is lost to the system. If the property in these and similar districts were taxed at substantially the same rate as the rest of the property in the state, the system could have hundreds of millions of additional dollars at its disposal. Whether this additional revenue were used to increase the attainable equalized funding level, ease the State's burden, or lower the tax rate each district must impose, the system would be made more efficient simply by utilizing the resources in the wealthy districts to the same extent that the remainder of the state's resources are utilized.
There are vast inefficiencies in the structure of the current system. With 1052 school districts, some having as few as two students, and with up to twenty districts within a single county, duplicative administrative costs are unavoidable.[13] Consolidation of school districts is one available avenue toward greater efficiency in our school finance system.
Another approach to efficiency is tax base consolidation. Senate Bill 1 expressly provides that future legislatures may use other methods to achieve fiscal neutrality, including "redefining the tax base." Tex. Educ.Code § 16.001(d). We disagree with the district court's observation that this option "appears to run afoul of certain constitutional provisions related to taxation." The district court was apparently concerned that consolidation of tax bases violated this Court's opinion in Love v. City of Dallas, 120 Tex. 351, 40 S.W.2d 20 (1931). In that case, we held that the City of Dallas could not be compelled to educate high school students who resided outside of the school district, which the city then operated. The decision rested in part upon our interpretation of article VII, section 3 of the Constitution, which we said "contemplates that districts shall be organized and taxes levied for the education of scholastics within the districts." Id. at 367, 40 S.W.2d at 27 (emphasis added). We also said that "the necessary implication from the constitutional provision is that the Legislature cannot compel one district to construct buildings and levy taxes for the education of nonresident pupils." Id. (emphasis added).
Article VII of the Constitution accords the Legislature broad discretion to create school districts and define their taxing authority.[14] The Constitution does not present a barrier to the general concept of tax base consolidation, and nothing in Love prevents creation of school districts along county or other lines for the purpose of collecting tax revenue and distributing it to other school districts within their boundaries.[15]*498 While consolidating tax bases may not alone assure substantially equal access to similar revenues, the district court erred in concluding that it is constitutionally prohibited.
We do not undertake lightly to strike down an act of the Legislature. We are mindful of the very serious practical and historical difficulties which attend the Legislature in devising an efficient system, and we recognize the efforts of the legislative and executive departments to achieve this goal. We do not prescribe the means which the Legislature must employ in fulfilling its duty. Nor do we suggest that an efficient funding system will, by itself, solve all of the many challenges facing public education in Texas today. Nevertheless, our duty is plain: we must measure the public school finance system by the standard of efficiency ordained by the people in our Constitution. The test for whether a system meets that standard is set forth in our opinion in Edgewood I. Ill S.W.2d at 397-98. Under that standard, we therefore hold as a matter of law that the public school finance system continues to violate article VII, section 1 of the Constitution.
While we share the district court's desire to avoid disruption of the educational process, we must heed our duty to ensure Texas students the efficient education system guaranteed them by the Constitution. See Morton v. Gordon, Dallam 396, 397-98 (Tex.1841). If the educational process is to be disrupted, it will be because the demands of the Constitution cannot be further postponed.

IV
The district court correctly concluded that conditions have not changed since Edgewood I because the public school finance system has not been altered to comply with article VII, section 1 of the Texas Constitution. The district court clearly abused its discretion in refusing to enforce the mandate of this Court issued in Edgewood I.
We therefore direct the district court to vacate that portion of its judgment which vacates the injunction affirmed by this Court in Edgewood I.[16] Because the deadlines set by that injunction have passed, we must modify those deadlines. However, the need for an efficient system remains as compelling today as it was when we last visited this issue, at which time we stated: "A remedy is long overdue. The legislature must take immediate action." 777 *499 S.W.2d at 399. Balancing the need for immediate action against the realities of the legislative process, and desiring to avoid or minimize disruption of the educational process, we stay the effect of the injunction until April 1, 1991.[17] The district court is directed not to extend this deadline or to modify this injunction.
We trust the district court will promptly comply, and we will withhold issuance of our writ unless it fails to do so.

OPINION ON MOTION FOR REHEARING
On motion for rehearing, plaintiffintervenors request that we modify our opinion to overrule Love v. City of Dallas, 120 Tex. 351, 40 S.W.2d 20 (1931), or interpret that case "in a manner that would permit the [state-wide] recapture of local ad valorem revenues for purposes of equalization." We believe Love is sound and decline to overrule or modify it. Moreover, the interpretation requested by plaintiff-intervenors would violate the Texas Constitution. Accordingly, we overrule the motion for rehearing.
In Love, this Court held that the City of Dallas could not be compelled to educate students who resided outside of the city's school district. We held that article VII, section 3 of our Constitution only "contemplates that districts shall be organized and taxes levied for the education of scholastics within the districts." 120 Tex. at 367, 40 S.W.2d at 27. Focusing on the Legislature's power to create school districts and define their taxing authority, we noted in this opinion that, consistent with Love and contrary to the district court's suggestion, tax base consolidation could be achieved through the creation of new school districts. We said these school districts could be organized along county or other lines and could be given the authority to generate local property tax revenue for all of the other school districts within their boundaries.
Plaintiff-intervenors now urge us to go further. They argue that all school districts are mere creatures of the state, and "in reality, all taxes raised at the local level are indeed State taxes subject to state-wide recapture for purposes of equalization." Their position raises the question of whether the Legislature may constitutionally authorize school districts to generate and spend local taxes to enrich or supplement an efficient system.[1] Because the Constitution does permit such enrichment, without equalization, local taxes cannot be considered "State taxes subject to state-wide recapture."
Our Constitution clearly recognizes the distinction between state and local taxes, and the latter are not mere creatures of the former. The provision that "[n]o State ad valorem taxes shall be levied upon any property in this State," Tex. Const, art. VIII, § 1-e, prohibits the Legislature from merely recharacterizing a local property tax as a "state tax." Article VII, section 3, however, states that "the Legislature may authorize an additional ad valorem tax to be levied and collected within all school districts heretofore formed or hereafter formed, for the further maintenance of public free schools, and for the erection and equipment of school buildings therein." Tex. Const, art. VII, § 3 (emphasis added). These constitutional provisions mandate that local tax revenue is not subject to state-wide recapture.
*500 This conclusion highlights the basic constitutional distinction between the State's primary obligation and the local districts' secondary contributions. The current system remains unconstitutional not because any unequalized local supplementation is employed, but because the State relies so heavily on unequalized local funding in attempting to discharge its duty to "make suitable provision for the support and maintenance of an efficient system of public free schools." Tex. Const, art. VII, § l.[2] Once the Legislature provides an efficient system in compliance with article VII, section 1, it may, so long as efficiency is maintained, authorize local school districts to supplement their educational resources if local property owners approve an additional local' property tax.[3]
Because the relief sought by plaintiff-intervenors would violate the Constitution, their motion for rehearing is overruled.[4] This Court will entertain no further motions for rehearing in this cause. Tex.R. App.P. 190(d).

GONZALEZ, Justice, concurring.
In Edgewood I, we held that the state's school financing system was neither financially efficient nor efficient in the sense of providing for a "general diffusion of knowledge" statewide, and therefore it violated article VII, section 1 of the Texas Constitution. 777 S.W.2d at 395, 397 (Tex. 1989). We further declared that we would not instruct the legislature as to the specifics of the legislation it should enact; nor did we order it to raise taxes. We stated that the legislature has the primary responsibility to decide how best to achieve an efficient system.
The issue before us in Edgewood II was whether this violation remained following the enactment of Senate Bill 1 by the 71st Legislature. 804 S.W.2d 493 (1991). We held that the fundamental flaw of Senate Bill 1 "lies not in any particular provisions but in its overall failure to restructure the system." Id. at 496. We concluded that since the public school finance system had not been altered to comply with article VII, section 1 of the Texas Constitution, the district court abused its discretion in refusing to enforce the mandate issued in Edgewood I.
We should not speculate or interfere with the ongoing legislative debate as to how to meet the mandates of Edgewood I or Edgewood II; nor should we get into the business of giving the legislature pre-clearance on proposed legislation. See Muskrat v. United States, 219 U.S. 346, 362, 31 S.Ct. 250, 255, 55 L.Ed. 246 (1911). To say now what might be constitutional would get into the area of advisory opinions. We have repeatedly held that under our constitution, judicial power does not embrace the *501 giving of advisory opinions. Firemen's Ins. Co. v. Burch, 442 S.W.2d 331, 333 (Tex. 1969); Correa v. First Court of Appeals, 795 S.W.2d 704, 705 (Tex.1990).
As our court stated in Morrow v. Corbin, 122 Tex. 553, 62 S.W.2d 641, 643 (1933):
Ordinarily, we believe the rendition of advisory opinions is to be regarded as the exercise of executive rather than judicial power. This seems to have been the conception of those who framed the Constitution, since by that instrument the Attorney General, a member of the Executive Department, is the only state officer expressly authorized to render such opinions. State Constitution, article 4, §§ 1, 22. At any rate, the rendition of advisory opinions has generally been held not to be the exercise of judicial power, (citations omitted).
For all these reasons, I would overrule the motion for rehearing without an opinion.
GAMMAGE, Justice, concurring.
The motion for rehearing before this court properly raises only one issuethe viability of our earlier opinion in Love v. City of Dallas, 120 Tex. 351, 40 S.W.2d 20 (1931). Since nothing in either Edgewood I, 777 S.W.2d 391, or Edgewood II, 804 S.W.2d 491, suggests that Love was overruled, the motion should be overruled without opinion.
Any opinion issued on the motion should narrowly confine itself to the question presented. The majority's gratuitous action in addressing matters not raised in the motion for rehearing is both unnecessary and inappropriate, amounts to an advisory opinion, and is calculated to further confound and confuse the public and the legislative process.
For these reasons, I concur in the overruling of the motion for rehearing but would have done so without an opinion, and further join Justice Doggett in his concurring opinion.
DOGGETT, Justice, concurring.
Twice this court has labored arduously to speak with one, clear voice concerning this most significant case. Twice this court has achieved consensus in opinions, signed by a single member, but incorporating the work of all. Tragically, today this unity has been abruptly abandoned, shattering the good faith upon which it was founded. Determined to react to extrajudicial developments, the court exceeds its jurisdiction, contravenes its rules, and ignores limitations imposed on it by tradition and the Constitution. It muddles the law and meddles in the legislative process. Advice not properly sought is offered anyway, despite the warning of the Chairman of the Senate Education Committee that further judicial interference will be disruptive and his indication that the Legislature already has all the judicial advice necessary "to remedy the constitutionally flawed system of public education____" Amicus Brief on Motion for Rehearing, Sen. Carl Parker, at 2; see also Supplemental Response of Plaintiff-Appellants to Motion for Rehearing at 2 (Further action by the court "would likely impede, rather than facilitate this [legislative] process."). Accordingly, the opinion on rehearing constitutes a frantic rush to influence the final stages of current legislative deliberations and will only prolong correction of our inefficient educational system at the expense of the school children of Texas.[1]
Today a judge expounds on social policy preferences rather than resolving a motion. The underlying need for writing arises from the fear that the Legislature may otherwise fail to satisfy certain judicial desires, not that it may inadvertently pursue some further unconstitutional course. The restraint observed by a unified court has become the activism promoted by a majority of a divided one. For the reasons set forth herein, I dissent from the opinion on the motion for rehearing in the strongest *502 possible terms but concur with the decision that this motion should be overruled.
This self-styled "Opinion on Motion for Rehearing" is a misnomer. It is not a true opinion generated in response to a party's motion for rehearing; rather, it is an answer to a question that a movant never asked. The only motion before us consists of four narrowly crafted paragraphs concerning the validity of a single prior opinion:
This Motion for Rehearing is filed for the limited purpose of requesting modification or clarification of this Court's opinion with respect to the continued force and effect of Love v. City of Dallas, 120 Tex. 351, 40 S.W.2d 20 (1931).
Plaintiff-Intervenors' Motion for Rehearing at 1 (emphasis added). If the court believed that this request was either meritless or inappropriate, the direct response was simply to overrule the motion as recommended by three of the succinct replies. Instead, by overwriting and miswriting the court offers observations that are strangely at variance with one aspect of the recapture issue on which the Defendants, the Plaintiff-Appellants, and the Plaintiff-Intervenors all agree.[2]
The court's main objective is to misuse one party's pleading on a single issue to benefit an opponent on other unrelated concerns.[3] It wrongfully claims that the movant's
position raises the question of whether the legislature may constitutionally authorize school districts to generate and spend local taxes to enrich or supplement an efficient system.
804 S.W.2d at 499. The motion does not even remotely ask any such question. Rather, in a desperate effort to justify its misguided action, the court rephrases the motion to present a question that a judge wants to answer. The opinion converts the issue of whether locally-raised taxes may be used to fund other school districts elsewhere in the state to whether locally-raised taxes may be used locally to provide supplemental funds in the same district.
Today's opinion reacts not to a movant's properly filed pleading but solely to exigencies evidenced in pleadings of a different sortmedia reports and commentaries, of the type set forth in Appendix A to this dissent. While constitutional interpretation involves some adjustment to changing societal conditions and must reflect "the understanding that the Constitution was ratified to function as an organic document to govern society and institutions as they evolve through time," Edgewood Ind. School Dist. v. Kirby, 111 S.W.2d 391, 394 (Tex. 1989) {Edgewood I); Damon v. Cornett, 781 S.W.2d 597, 599 (Tex.1989), we should not abruptly reinterpret the basic fabric of our jurisprudence because a judge is startled by what he reads in the newspaper. The true message sent forth today is "don't write a legal brief, write a political column." This is apparently the first time in its 151-year history that the court has operated in the manner it has today.
Indicative of the true nature of this opinion is the near total absence of supporting *503 legal authority excepting the single case raised by movants that provided the convenient excuse for further writing. Perhaps this is because the only true precedent for today's action is an earlier embarrassing chapter in Texas jurisprudence that the court does not cite. Without parties, attorneys, or a pending appealsolely on its own initiativethis court once declared legislation unconstitutional. See In re House Bill No. 537 of the Thirty-Eighth Legislature, 113 Tex. 367, 256 S.W. 573 (1923).[4] While dressed in seemingly more respectable language, a similar judicial encroachment has occurred again today.
In denying the motion for rehearing and writing on this completely separate issue, the opinion deprives the movants of any opportunity to complain or request correction of this new discussion. Having received, to their surprise and undoubted chagrin, an answer to a question they did not ask, the movants can never again be heard because "[t]his court will entertain no further motions for rehearing in this cause." 804 S.W.2d at 500. See Tex.R.App.P. 190(d). By including analysis of a new issue in an opinion denying the motion for rehearing, the court chisels these words in stone, arrogating to itself an authority beyond review. This precedent for deciding questions not properly presented should alert appellate lawyers in all cases to file motions for rehearing at their peril. Asking for rehearing is risky business because the court in its enthusiasm may rule on subjects not presented while denying further review.
And, having accomplished this coup today, why is a motion for rehearing even necessary? Since the court may issue opinions unrelated to points raised by a movant, the motion itself is superfluous. Why should the court not encourage public debate of an opinion and thereafter fix whatever is necessary, resolving every dissatisfaction, and dispelling any confusion? This would further save litigants the expense of paying lawyers to file motions and provide legal advice.
The thickest camouflage for today's judicial handiwork is provided by the disingenuous suggestion that a Friday afternoon reply by Attorney General Dan Morales to the only motion for rehearing had something to do with this Monday opinion. The only request from that belated filing on which the court acts is the suggestion that we answer at least one of the four questions addressed to us in an amicus brief. Defendants' Response to Motion for Rehearing at 4-5. Eleven members of the Legislature asked us to engage in what they describe as the "extraordinary" step of prejudging their conduct.[5] Amicus Brief on Motion for Rehearing, Rep. Junell, at 5. Having already determined to respond to newspaper pleadings, today's opinion has no problem with simultaneously answering the query of these nonparties despite its impropriety.[6]
From the birth of our nation, courts have declined requests from officials in other branches of government to issue advisory opinions.[7] In Texas this matter was specifically *504 addressed in the Constitution, see article IV, section 22, and interpreted by our court: "the Attorney General, a member of the Executive Department, is the only state officer expressly authorized to render such [advisory] opinions." Morrow v. Corbin, 122 Tex. 553, 62 S.W.2d 641, 644 (1933); see also Tex. Const, art. V, § 3 (delimiting Supreme Court's jurisdiction); Tex. Gov't Code Ann. § 402.042 (Vernon 1990) (broadening the Attorney General's power to issue opinion letters).
Because rendering such advice has been constitutionally deemed to be an executive rather than a judicial function, this court has previously refused to issue such opinions even upon request of another court. See Morrow, 62 S.W.2d at 644. We have declared unconstitutional an enactment purporting to authorize our offering trial courts prejudgment advice on the constitutionality of state statutes and regulations. Id., 62 S.W.2d at 643-44. More recently, by enacting a resolution submitting a constitutional amendment for citizens' approval to authorize our answering certified questions from federal appellate courts, the Legislature recognized that it could not statutorily confer this court with advisory power.[8]
Today's opinion on rehearing subjects the court to requests for advisory opinions not just from all litigants, but any person who files an amicus brief or writes an editorial. Once a court engages in the business of offering such advice that business will prosper. Today one amicus presents four queries; tomorrow it may be forty.[9] Soon we can expect inquiries concerning our view of a lottery or the methodology for replacing the State Board of Insurance. The volume of opinions issued by the Attorney General, some 193 in 1990 alone, 16 Tex.Reg. 289-92 (1991), suggests the breadth of this task.
More importantly the process in which the court today engages diminishes the quality of our opinions. As Justice Felix Frankfurter noted before his service on the United States Supreme Court:
The advisory opinion deprives constitutional interpretation of the judgment of the legislature upon facts, of the effective defence of legislation as an application of settled legal principles to new situations, and of the means of securing new facts through the process of legislation ____ [T]o submit legislative proposals to the judicial judgment, instead of the deliberate decision of the legislature, is to submit legislative doubts instead of legislative convictions. The whole focus of the judicial vision becomes thereby altered.

Frankfurther, A Note on Advisory Opinions, 37 Harv.L.Rev. 1002, 1005 (1924) (emphasis added).
I am keenly aware of the many obstacles and limitations imposed on members of the Legislature in undertaking the monumental task of restructuring the school finance system. But judges must follow time-honored limitations of a different character. Our function is to uphold the Constitution and, under appropriate circumstances, to refine and develop the common law.[10] It is *505 neither to draft legislation nor to render advisory opinions.
Courts safeguard liberties not only by their action but by their restraint. Through addressing only the questions properly presented in the context of genuine controversies, they preserve public confidence in our third branch of government as an arbiter of real disputes rather than as a clearinghouse for advice on contemporary problems. Respect for judicial authority arises from restraint in its use.
Undoubtedly, to some there is a certain allure to the notion of this court working hand-in-hand with the Legislature as different drafts are submitted for review. Each chapter, section, and sentence could enjoy the careful scrutiny of this court. We could negotiate away any misunderstanding over constitutional requisites perhaps at the same time that the Legislature was resolving the court's budget.
While this approach might result in resolution of one significant problem, it would eventually transform the court into an extension of the Legislature. With its three separate branches of government,[11] our democracy does not always resolve problems in the most expeditious manner. To secure a considered, independent judicial review, we regard some delay acceptable as we sacrifice the gratification immediate answers bring. Disregarding our traditional separation of powers to provide a quick-fix answer undermines the foundation of democracy. Texans excluded from the joint legislative and judicial decision-making process would be denied all opportunity for unbiased judicial review of legislative conduct. Judges would become mere appendages to other branches of government.
Today's opinion demonstrates the danger of overreaching to answer that which has not been properly asked. Our decision on local enrichment in Edgewood I, 111 S.W.2d at 397-98, was straightforward, and has been a puzzle primarily to those who preferred not to comprehend it or who disliked what they read. As a postscript to the court's prior unanimous writings, this most recent effort adds more confusion than clarity.
The few generalizations about local supplementation,[12] without supporting legal authority or meaningful analysis, reflect the superficial nature of the court's consideration of this very important question. Nor, despite the court's contrary insinuation, 804 S.W.2d at 493 n. 1, have the parties fully briefed and argued this issue. The movant on rehearing did not, of course, brief a question it did not ask. Fortunately, today's hasty supplement is pure dicta which is in no way binding on this or other courts in the future and is of highly dubious authoritative value. See Boswell v. Pannell, 107 Tex. 433, 180 S.W. 593, 596 (1915).
A final reason to avoid the temptation of pontificating is that the court lacks jurisdiction to do so here. By declining to take direct appeal jurisdiction in this cause and "treat[ing] this proceeding as being [solely] in the nature of an original mandamus proceeding to direct the district court to reinstate our injunction," 804 S.W.2d at 493, the court chose not to accept authority to *506 address many issues raised in this proceeding, including cross-points brought by the defendants. The opinion in this cause on first hearing carefully sought to observe these jurisdictional limitations, declining to pass on the question of attorney's fees, "which has nothing to do with the enforcement of our mandate," 804 S.W.2d at 493, n. 4, and carefully limiting our consideration of other questions unnecessary to the ultimate issue of enforcement. Id. at (refusing to address "conflicting prognostications as to whether Senate Bill 1 can or will be implemented to achieve efficiency among 95% of students"). Because we may address only those matters directly affecting enforcement of our prior mandate, the question of local supplementation is not properly before this court. Moreover, a determination of this matter would amount to an inappropriate final resolution of an issue on the merits in a mandamus proceeding that is limited solely to considering whether the trial court abused its discretion. See Brownson v. Smith, 93 Tex. 614, 57 S.W. 570 (1900) (refusing to pass on constitutional question that would clarify "the uncertainty which surrounds [the Victoria] school system" because resolution of the issue would not affect whether the writ of mandamus should issue).
The fact that it is racing to publish this opinion before the other branches provide their own solution bespeaks the majority's eagerness to legislate rather than adjudicate. By the public display of disunity and new words of equivocation, today's opinion ensures that this litigation which may be finally nearing an end will go on indefinitely. Neither the Legislature, the parties, nor school districts can act with any assurance concerning what this court will do in the future.
Thankfully Texas judges can be held accountable by the people through the election process. That process, however, has been the source of certain contradictions that have become evident today. Recognizing that Texans do not want even elected judges interfering unnecessarily in their affairs, some candidates have found it increasingly beneficial to identify themselves as proponents of judicial restraint and their opponents as judicial activists. To some, "restraint" is generally synonymous with turning back the clock. In reality, however, for them it is an elastic, self-assumed label describing their judicial conduct, expediently adjusted to fit whatever they wish to write. As they define it, their own conduct is an example of conservatism and restraint, even if, as in this case, it ignores precedent, the rules, and the Constitution. To me, it meansregardless of parties or causesa reluctance to exceed our constitutional role as judges and a refusal to engage in the type of conscious manipulation that has occurred here. Today's opinion offering advice where none is properly sought represents true activism of the most dangerous type. It reveals the true extent of commitment to restraint by those who sometimes celebrate its virtues so joyously.

NOTES
[1]  Act of June 7, 1990, 71st Leg., 6th C.S., ch. 1, 1990 Tex.Gen. Laws 1.
[2]  The parties did not complain to this Court of the district court's extension of our May 1, 1990 deadline, and we should not be viewed as approving this action.
[3]  We noted when we issued our opinion in Edgewood I that the Governor had called the Legislature into special session beginning November 14, 1989. 777 S.W.2d at 399 n. 8. The school funding system was not included in the call, however, until the third special session of the Legislature, which began February 27, 1990. That session adjourned without adopting corrective legislation, as did the fourth special session, which immediately followed and adjourned on May 1, 1990. At the fifth special session, which began May 2, 1990, a school finance bill was passed by both houses of the Legislature but was vetoed by the Governor on May 22, 1990. Tex.S.B. 1, S.J. of Tex. 71st Leg., 5th C.S. 145 (1990). Senate Bill 1 was enacted during the sixth special session.
[4]  Plaintiffs also complain that the district court erred in refusing to award them the entire amount of attorney fees requested. This complaint has nothing to do with the enforcement of our mandate. Moreover, on the record before us, the issue is not one over which we will exercise direct appeal jurisdiction. See Tex.R. App.P. 140(b). Plaintiffs' appeal on this issue is therefore dismissed, without prejudice to seeking review in the court of appeals in accordance with appellate rules. See TexR.App.P. 140(e).
[5]  "The Legislature shall have the power to provide by law, for an appeal direct to the Supreme Court of this State from an order of any trial court granting or denying an interlocutory or permanent injunction on the grounds of the constitutionality or unconstitutionality of any statute of this State, or on the validity or invalidity of any administrative order issued by any state agency under any statute of this State."
[6]  "An appeal may be taken directly to the supreme court from an order of a trial court granting or denying an interlocutory or permanent injunction on the ground of the constitutionality of a statute of this state. It is the duty of the supreme court to prescribe the necessary rules of procedure to be followed in perfecting the appeal."
[7]  Senate Bill 1 amends section 16.001(c)(1) of the Education Code to read: "the yield of state and local educational program revenue per pupil per cent of effective tax effort shall not be statistically significantly related to local taxable wealth per student for at least those districts in which 95 percent of students attend school." The concept of similar yield for similar rates of taxation has been termed "fiscal neutrality."
[8]  The senior policy makers are those who serve on the Legislative Education Board (LEB), the Legislative Budget Board (LBB), and Foundation School Fund Budget Committee (FSFBC). The LEB and the LBB are charged by Senate Bill 1 with the duty of carrying out the various studies. The LEB reports to the FSFBC regarding the funding levels indicated by the studies. The FSFBC, comprised of the Governor, Lieutenant Governor and Comptroller, ultimately makes funding recommendations to the legislature.
[9]  Because certain pupils, such as those needing bilingual instruction or participating in special education programs, are more expensive to educate than others, most educational revenue is distributed according to complex formulas that assign "weights" to students with different needs.
[10]  However, under the current system, all districts receive about $300 per student from the Available School Fund established by article VII, section 5(a) of the Constitution. The Constitution does not require this distribution, stating only that "the available fund herein provided shall be distributed to the several counties according to their scholastic population and applied in such manner as may be provided by law." The manner of distribution is provided by statute. Tex.Educ.Code § 15.10.
[11]  The district court also described a third tier, consisting of further local supplementation of the public school finance system. The question of local enrichment continues to be controlled by this Court's opinion in Edgewood I, 111 S.W.2d at 397-98.
[12]  As explained in the Governor's message vetoing the predecessor to Senate Bill 1, which had a substantially similar funding approach:

It is the finance system itself which is at the heart of the Texas Supreme Court holding that our education system violates the Constitution. The current system is not fair, and it is not equitable. Yet, S.B. 1 would basically continue the current system of subsidizing wealthier school districts at the expense of property poor school districts.... This bill places an unfair burden on local property taxpayers to support an inequitable system. S.J. of Tex., 71st Leg., 5th C.S. 145 (1990).
[13]  Allamoore CSD and Juno CSD have two students each, and Harris County contains twenty independent school districts. Moreover, Bexar, Dallas, Hidalgo, McLennan and Tarrant Counties each contain fifteen or more school districts.
[14]  Since this constitutional grant of power does not specify the details of statutory implementation, a number of alternatives are available to the Legislature. One such method, already in place, allows voters to "create an additional countywide school district which may exercise in and for the entire territory of the county the taxing power conferred on school districts by Article VII, Section 3, of the Texas Constitution." Tex.Educ.Code § 18.01. The voters are permitted to implement such a taxing scheme "without affecting the operation of any existing school district within the county." Id. Chapter 18 of the Education Code is also consistent with counties' constitutional role in distributing educational resources. See Tex. Const, art. VII, § 5.
[15]  Article VII, section 3 of the Constitution expressly authorizes the Legislature to provide for school districts "composed of territory wholly within a county or in parts of two or more counties." Many school districts, such as Nueces Canyon ISD, Uvalde Consolidated ISD and Sands ISD, currently encompass parts of several counties.
[16]  The injunction originally issued by the district court was as follows:

INJUNCTION
It is hereby ORDERED that William N. Kirby, Commissioner of Education, the Texas State Board of Education, and Robert Bullock, Comptroller of the State of Texas and their successors, and each of them, be and are hereby enjoined from giving any force and effect to the sections of the Texas Education Code relating to the financing of education, including the Foundation School Program Act (Chapter 16 of the Texas Education Code); specifically said Defendants are hereby enjoined from distributing any money under the current Texas School Financing System (Texas Education Code § 16.01, et seq., implemented in conjunction with local school district boundaries that contain unequal taxable property wealth for the financing of public education).
It is further ORDERED, that this injunction shall in no way be construed as enjoining Defendants, their agents, successors, employees, attorneys, and persons acting in concert with them or under their direction, from enforcing or otherwise implementing any other provisions of the Texas Education Code.
In order to allow Defendants to pursue their appeal, and should this decree be upheld on appeal, to allow sufficient time to enact a constitutionally sufficient plan for funding public education, this injunction is stayed until September 1, 1989. It is further ODERED that in the event the legislature enacts a constitutionally sufficient plan by September 1, 1989, this injunction is further stayed until September 1, 1990, in recognition that any modified funding system may require a period of time for implementation. This requirement that the modified system be in place by September 1, 1990, is not intended to require that said modified system be fully implemented by September 1, 1990.
[17]  Specifically, we modify the injunction by extending the date September 1, 1989, to April 1, 1991, and the date September 1, 1990, to September 1, 1991.
[1]  In addition, defendants' response to plaintiffintervenors' motion for rehearing submits that "there continues to be considerable discussion of the meaning of the language of Edgewood I referenced in footnote 11 of Edgewood II." Defendants therefore "urge the Court to clarify whether local enrichment violates the Constitution as interpreted by Edgewood I and Edgewood II if the yield from local tax effort varies because of the value of a local community's tax base." Defendants have consistently urged the court to clarify whether unequalized local enrichment is permissible under the Constitution. Indeed, their original brief asserted by crosspoint that the district court erred in "applying a standard of total equality" that mandated the elimination of all unequalized local enrichment. The motion for rehearing and defendants' response suggest the need for greater clarity in our resolution of defendants' argument.
[2]  As explained in Edgewood I, the mandate of efficiency in article VII, section 1, while not requiring "a per capita distribution" or absolute equality, does prohibit the "gross inequalities" and "vast disparities" resulting from "concentrations of resources in property-rich school districts that are taxing low when property-poor districts that are taxing high cannot generate sufficient revenues to meet even minimum standards." 777 S.W.2d at 395, 396, 397. We therefore required "a direct and close correlation between a district's tax effort and the educational resources available to it." Id. at 397.
[3]  In advocating the amendment of article VII, section 3 to permit local supplementation, Governor Ireland explained that local districts should be "allowed to levy and collect an additional tax for the purpose of aiding the State in its efforts at giving the people an education." Message of Governor Ireland, reprinted in Texas S.J., 18th Legislature, Regular Session, 66, 67 (January 29, 1883) (emphasis added).
[4]  In their response to the motion for rehearing, defendant-intervenors express concern that if the Legislature fails to enact a constitutional school finance bill by April 1, 1991, our injunction will preclude the State from honoring its obligations as the guarantor of bonds issued by local school districts. These concerns are unfounded. We adopt the language of the trial court's original order in this regard, modifying the September 1, 1990, date in that portion of the order to September 1, 1991. Our deadline of April 1, 1991, for legislative action remains unchanged.
[1]  Judicial tampering that prolongs an equitable solution is especially discouraging given the time that has elapsed since this cause was originally filed. A child then in the first grade is now in the eighth. With today's interference, another generation of children may conclude their public schooling before complete reform is achieved.
[2]  Defendants' Response to Motion for Rehearing, at 2-3; Plaintiff-Appellants' Response to Motion for Rehearing; Plaintiff-Intervenors' Motion for Rehearing.
[3]  The applicable procedural rule speaks clearly concerning the presentment and consideration of such motions:

A motion for rehearing may be filed with the clerk of the court within fifteen days after the date of rendition of the judgment.... The points relied upon for the rehearing shall be distinctly specified in the motion. The party filing such motion shall deliver or mail to each party, or his attorney of record, a true copy of such motion.... Tex.R.App.P. 190 (emphasis supplied). This rule limits our consideration to points brought forward by the parties. See also, e.g., Tex.R. App.P. 131(e) (points of error brought to supreme court must be presented in motion for rehearing in court of appeals); Lone Star Steel Co. v. Owens, 302 S.W.2d 213, 223 (Tex.Civ.App. Texarkana 1957, writ ref'd n.r.e.) (complaints not raised in a motion for rehearing are no longer before the courts of appeals for decision); State Bar of Texas, Appellate Procedure in Texas 552 (2d ed. 1979). The court today ignores requirements ordinarily imposed on the preservation and presentation of points of error. At issue here, however, is much more than a debate concerning the legal intricacies of appellate procedure.
[4]  See also Calvert, Declaratory Judgments in TexasMandatory or Discretionary?, 14 St. Mary's L.J. 1, 3 n. 3 (1982); Note, CourtsConstitutionality of Declaratory Judgments, 3 Tex.L. Rev. 483, 485 (1925).
[5]  One of these members ironically achieves more here as an amicus than he could at the trial court where an order striking his intervention was issued. Transcript at 168-69.
[6]  See Fri v. Sierra Club, 414 U.S. 884, 94 S.Ct. 33, 38 L.Ed.2d 132 (1973) (finding that an amicus has no standing to independently seek a rehearing); Texas v. Jefferson Iron Co., 60 Tex. 312, 315 (1883) ("Our court has recognized the right of an amicus curiae to speak, and has held that while such volunteer action of counsel is permissible," the court, "upon being so informed, could do only that which it could do without such action of counsel, and no more."); see also Moseby v. Burrow, 52 Tex. 396, 403 (1880).

An amicus curiae is limited to making suggestions to the court, Jones v. City of Jefferson, 66 Tex. 576, 1 S.W. 903, 904 (1886), not posing new questions. See generally, J. Denton, Appellate Procedure in Texas 355 (O. Walker ed. 2d ed. 1979); Krislov, The Amicus Curiae Brief: From Friendship to Advocacy, 72 Yale L.J. 694, 695 (1963).
[7]  Through a letter written by his Secretary of State Thomas Jefferson, President George Washington sought advice from the Supreme Court concerning several legal questions to "secure us against errors dangerous to the peace of the United States," and to "insure the respect of all parties." Letter from Thomas Jefferson to Chief Justice Jay (July 18, 1793), reprinted in W. Murphy & C. Pritchett, Courts, Judges, and Politics 225-26 (3d ed. 1979). While regretting any embarrassment that might befall the administration, the justices refused his request lest they violate the careful constitutional division of powers. Id. at 226.
[8]  Tex.Const. art. V, § 3-c. The necessity for the amendment was explained: "[T]he Texas Supreme Court has determined that under the Texas Constitution judicial power does not embrace giving advisory opinions." Senate Judiciary Committee, Bill Analysis, S.J.R. 10, § 1 R.S. (1985).
[9]  As explained by another legislator: "Once the Court demonstrates its willingness to advise the legislature on the details of public school finance legislation, the questions will not end." Amicus Brief on Motion for Rehearing, Sen. Carl Parker, at 2. Perhaps to underscore his point he sought our advice in a subsequent filing by posing four questions whose answers would bestow judicial preclearance on specific pending legislation. Motion for Leave to Supplement and Amend Amicus Curiae Brief, Sen. Carl Parker.
[10]  See El Chico Corp. v. Poole, 732 S.W.2d 306, 311 (Tex.1987); Winters v. Houston Chronicle Publishing Co., 795 S.W.2d 723, 725-26 (Tex. 1990) (Doggett, J., concurring).
[11]  See Bruff, Separation of Powers Under the Texas Constitution, 68 Tex.L.Rev. 1337, 1337 (1990) ("A strong separation-of-powers tradition is a prominent feature" of Texas constitutional law.).
[12]  Today's opinion leaves unclear to what extent, if any, legislative enactments can restrict the taxing authority of school districts. If the Texas Constitution bars recapture, 804 S.W.2d 491, why are not other limitations equally flawed? Are legislatively-authorized roll back elections now an unconstitutional interference with local supplementation? Tex.Tax Code Ann. § 26.08 (Vernon 1982 Si Supp.1991). Does the opinion on rehearing make unconstitutional the State Property Tax Board, which is authorized to ensure uniformity in local tax appraisal practices and procedures? Tex.Educ.Code Ann. § 11.71 (Vernon 1991). What effect does it have on those provisions historically included in school financing legislation that condition the receipt of certain benefits, such as accreditation, on the levying of a set minimum local tax rate? By apparently barring similar conditions based on state recapture, the opinion casts a constitutional cloud on other traditionally imposed legislative conditions upon taxation by school districts. By writing without considering the ramifications of overbroad and vague statements, the court, intending to grease the legislative works, simultaneously throws in a few wrenches.
