Before Justices YEAKEL, PATTERSON and POWERS.[*]
JOHN E. POWERS, Justice (Retired).
Southwestern Bell Telephone Company ("SWBT"), in an original action in district court, sued the Public Utility Commission ("PUC") and its commissioners for declaratory, mandamus, and injunctive relief.[1] AT & T Communications of Texas, L.P. ("AT & T") and Southwestern Bell Communications Services, Inc. ("SWBCS") intervened in the cause, the former in opposition to and the latter in support of SWBT's causes of action. SWBT and SWBCS appeal now from a district-court order denying SWBT's application for a temporary injunction restraining certain agency actions pending final hearing in district court. We will reverse the order and remand the cause to the district court.

THE CONTROVERSY
The material facts appear to be undisputed. SWBT provides telecommunications services in a specified "local access and transport area." Because SWBT is a local-exchange company, it may not provide long-distance service between a point within the area and a point outside the area. AT & T and SWBCS compete in providing such long-distance service. SWBCS is an affiliate of SWBT but is, and is required to be, a separate legal entity. See 47 U.S.C.A. §§ 271, 272 (West Supp. 2001). To connect an intrastate long-distance call to SWBT's local network, long-distance carriers such as AT & T and SWBCS must pay SWBT a "switched-access charge." The amount SWBT charges is the subject of the present controversy.
*26 The legislature amended the Public Utility Regulatory Act (PURA) in 1995 by adding provisions for "incentive regulation" to "provide a framework for an orderly transition" from traditional rate-of-return regulation for local-exchange companies that elected to be governed by the new form of regulation. Tex. Util.Code Ann. ("PURA" hereafter) § 58.001(1) (West 1998). SWBT, an "incumbent local exchange company," elected to be governed by the new incentive-regulation statutes. See id. §§ 58.001, .002-.267. The legislature in 1997 added to the incentive-regulations as follows:
§ 58.025. Complaint or Hearing
(a) An electing company is not, under any circumstances, subject to a complaint, hearing, or determination regarding the reasonableness of the company's:
(1) rates;
(2) overall revenues;
(3) return on invested capital; or
(4) net income.
(b) This section does not prohibit a complaint, hearing, or determination on an electing company's implementation and enforcement of a competitive safeguard required by Chapter 60.
Id. § 58.025.
Reasonable rates, overall revenues, return on invested capital, and net income are, of course, elements of rate-of-return regulationthe regulatory regime replaced by SWBT's election to submit to the incentive-regulation provisions of PURA. See id. §§ 58.051-.065.
The legislature added further to the incentive-regulation provisions in 1999. The 1999 amendments included the following:
§ 58.301. Switched Access Rate Reduction
An electing company with greater than five million access lines in this state [which includes SWBT] shall reduce its switched access rates on a combined originating and terminating basis[2] as follows:
(1) the electing company shall reduce switched access rates on a combined originating and terminating basis in effect on September 1, 1999, by one cent a minute; and
(2) the electing company shall reduce switched access rates on a combined originating and terminating basis by an additional two cents a minute on the earlier of:
(A) July 1, 2000; or
(B) the date the electing company, or its affiliate formed in compliance with 47 U.S.C. Section 272, as amended, actually begins providing interLATA services[3] in this state in accordance with the authorization required by 47 U.S.C. Section 271, as amended.
§ 58.302. Switched Access Rate Cap
(a) An electing company may not increase the per minute rates for switched access service on a combined originating and terminating basis above the lesser of:
(1) the rates for switched access services charged by that electing company on September 1, 1999, as may be further reduced on implementation *27 of the universal service fund under Chapter 56; or
(2) the applicable rate described by Section 58.301 as may be further reduced on implementation of the universal service fund under Chapter 56.
(b) Notwithstanding Subchapter F, Chapter 60, but subject to Section 60.001, an electing company may, on its own initiative, decrease a rate charged for switched access service to any amount above the long run incremental cost of the service.
§ 58.303. Switched Access Charge Study
(a) Not later than November 1, 1999, the [PUC] shall begin a review and evaluation of the rates for intrastate switched access service. The review shall include an evaluation of at least the following issues:
(1) whether alternative rate structures for recovery of switched access revenues are in the public interest and competitively neutral; and
(2) whether disparities in rates for switched access service between local exchange companies are in the public interest.
(b) The [PUC] shall file a report with the legislature not later than January 1, 2001. The report must include the [PUC's] recommendations on the issues reviewed and evaluated.
(c) This section expires September 1, 2001.
Id. §§ 58.301, .302, .303 (West Supp.2001) (footnotes omitted and added).
The PUC fixed the amount of SWBT's pre 1995 switched-access charges when the company was under rate-of-return regulation. The agency purposely fixed the amount above SWBT's related costs to compensate for the costs SWBT incurred in providing basic telephone service to all its customers as required by the statutory and agency policy of "universal service." See Public Util. Comm'n v. Allcomm Long Distance, Inc., 902 S.W.2d 662, 664 (Tex. App.Austin 1995, writ denied). After SWBT elected to be governed by incentive regulation, the amount of the company's fixed-access charges was arrested for a time at the pre 1995 amount, as provided in PURA sections 58.054-.267, then reduced thereafter according to the one-cent and two-cent incremental reductions mandated by PURA sections 58.301 and 58.302.[4] The subtractions left SWBT's switched-access charges at their current amount.
AT & T complained to the PUC that the current amount was so high that AT & T could not recover its related operating expenses, to its disadvantage in its competition with SWBCS in the intrastate long-distance market. While SWBCS paid the same amount as AT & T for switched-access service, SWBCS's status as a SWBT affiliate allegedly resulted in a subsidization of SWBCS's long-distance rates and an unjust and unfair profit for SWBT, derived from switched-access charges that *28 were allegedly anti-competitive, predatory, discriminatory, and unreasonably preferential.
AT & T prayed that the amount of SWBT's current switched-access charges be reduced after an agency hearing to equal the amount of SWBT's costs for providing the service. For interim relief, AT & T requested that the PUC order SWBT to reduce the amount of its charges to "match" the amounts fixed by the Federal Communications Commission for switched-access charges on interstate calls.
After receiving AT & T's complaint, the PUC: (1) assigned a docket number to the agency proceeding initiated by the complaint; (2) determined the agency had jurisdiction to grant some form of relief pursuant to the complaint; (3) requested the State Office of Administrative Hearings (SOAH) to assign an administrative-law judge to conduct a hearing and submit to the agency a proposal for decision; and, (4) issued a preliminary order outlining the course of the agency proceeding and the issues to be addressed, leaving it to the parties to raise other issues, if they wished, other than questions pertaining to the PUC's jurisdiction, the agency's authority to consider the AT & T complaint, and whether a "flow-through of reductions to SWBT's rates for switched-access services is necessary." The preliminary order also declared as follows:
The [PUC] has not ordered or has yet to determine if it should order reductions in SWBT's switched access rates. Therefore, the [PUC] believes it premature to address issues related to flow-through of reductions to access charges until such reductions are deemed appropriate.

(Emphasis added.)
By requiring that the hearing be conducted by an administrative-law judge supplied by SOAH and an attendant proposal for decision, the PUC has plainly indicated its intention to conduct a contested-case or adjudicative-type hearing directed at determining SWBT's legal rights respecting the current amount of its switched-access charges, as opposed to an exercise of the agency's investigatory power. See PURA § 14.053 (West 1998); Tex. Gov't Code Ann. §§ 2001.003(1), .058, .062 (West 2000).[5] A resulting agency decision would be subject to judicial review under the substantial-evidence scope and manner of review. See PURA § 15.001 (West 1998).
SWBT sued the PUC in the present cause, alleging the agency lacked jurisdiction[6] to reduce the amount of the company's switched-access charges or to hold a hearing for that purpose. For permanent relief, SWBT requested declaratory, mandamus, and injunctive relief accordingly. SWBT also applied for a temporary injunction restraining the PUC pendente lite from reducing the charges and from *29 holding an adjudicative hearing for that purpose. In an order signed March 14, 2001, the district court denied the application. SWBT brings now an interlocutory appeal from that order.

DISCUSSION AND HOLDINGS
The parties join issue on whether the district court abused its discretion by denying SWBT's application for temporary injunction. See Beaumont Bank v. Buller, N.A., 806 S.W.2d 223, 226 (Tex.1991); State v. Walker, 679 S.W.2d 484, 485 (Tex. 1984).
The merits of SWBT's causes of action are yet to be determined by the district court; the purpose of the requested temporary injunction is ancillary to that adjudication. A temporary injunction "may be and usually is issued in connection with any species of litigation where it is necessary to preserve the status quo pending a final determination of the rights of the parties." Turcotte v. Alice Nat'l Bank, 402 S.W.2d 894, 896 (Tex.1966); see Tex. Civ. Prac. & Rem.Code Ann. § 65.011 (West 1997). The district court was thus required to "determine how best to create or preserve a state of affairs such that it will be able upon conclusion of the full trial to render a meaningful decision for either party." Developments in the Law-Injunctions, 78 Harv. L.Rev. 994, 1056 (1965) (emphasis added). Having acquired jurisdiction in the present cause, the district court could "grant any writ, including the writ of injunction, necessary to administer justice between the parties, preserve the subject matter of the litigation, and make its judgment effective." City of Dallas v. Wright, 120 Tex. 190, 36 S.W.2d 973, 975 (1931) (emphasis added).
"The principles, practice, and procedure governing courts of equity shall govern proceedings in injunctions when the same are not in conflict with these rules or the provisions of the statutes." Tex.R. Civ. P. 693.[7] In cases like the present, the grant or denial of SWBT's application for temporary injunction depended upon whether the company showed (1) a probable, imminent, and irreparable injury that would occur before trial if the writ did not issue, and (2) a probable right, following trial on the merits, to the permanent relief SWBT requested in its petition. See Walling v. Metcalfe, 863 S.W.2d 56, 57 (Tex.1993); Harry M. Reasoner, Equity InjunctionsPractice and Procedure Criteria for Granting a Temporary Injunction when Only Questions of Law are Presented, 40 Tex. L.Rev. 409, 411 (1962).
Probable Injury. The current amount of SWBT's switched-access charges is the result of the company's unquestioned compliance with PURA sections 58.054, 58.301, and 58.302. SWBT contends it therefore has a statutory right to charge the current amount and, for reasons discussed hereafter, a statutory *30 immunity from any PUC hearing questioning that amount for the purpose of reducing it further to cure its allegedly anti-competitive, discriminatory, prejudicial, or unreasonably preferential effects. SWBT contends accordingly that the PUC lacks jurisdiction to modify the amount of switched-access charges mandated by the legislature or to conduct a hearing for that purpose. The PUC and AT & T contend the agency has jurisdiction to hold such a hearing and the power to reduce the amount of switched-access charges, if necessary, even if their amount is the result of compliance with the legislative mandates set out in PURA sections 58.054, 58.301, and 58.302. The controversy turns ultimately on the foregoing issues.
If SWBT's contentions are ultimately sustained by the district court, after a trial on the merits, it will be a meaningless and hollow victory if the agency has in the period before trial conducted a hearing and reduced the current amount of SWBT's switched-access charges, thereby extinguishing SWBT's claimed rights by actions the district court will have held ultra vires and unlawful. It appears to us then that a temporary injunction is the only practical and effective remedy to prevent such an eventuality. The statutory rights claimed by SWBT, if they exist, are larger than and different in character from a moral right to be free from the mere expense associated with a hearing before the PUC. The substance of SWBT's claimed rights is a right to be free of agency regulation in particulars the legislature has reserved for itself as the sovereign's immediate representatives. It seems to us then that the rights claimed by SWBT cannot be measured by a pecuniary standard or compensated by money if destroyed by unlawful agency action.
We therefore hold there is no reasonable basis in the record for a conclusion that SWBT is not exposed to a probable injury by reason of the PUC's preliminary order. See City of Sherman v. Public Util. Comm'n of Tex., 643 S.W.2d 681, 686 (Tex. 1983); Rutherford Oil Corp. v. General Land Office, 776 S.W.2d 232, 236 (Tex. App.Austin 1989, no writ); Sexton v. Mount Olivet Cemetery Ass'n, 720 S.W.2d 129, 145 (Tex.App.Austin 1986, writ ref'd n.r.e.); see generally Westheimer Indep. Sch. Dist. v. Brockette, 567 S.W.2d 780, 785 (Tex.1978).
Probable Right to Recover. Unless SWBT shows a probable right to declaratory, mandamus, or injunctive relief after trial on the merits, it does not establish a right to equitable relief in the form of a temporary injunction. How "probable" must the showing be? "At the hearing for a temporary writ of injunction, the applicant is not required to establish that [it] will prevail on final trial, ... the only question before the trial court is whether the applicant is entitled to preservation of the status quo pending trial on the merits." Walling, 863 S.W.2d at 58 (emphasis added).
"Clear evidence of irreparable injury should result in a less stringent requirement of certainty of victory; greater certainty of victory should result in a less stringent requirement of proof of irreparable injury." Developments in the Law Injunctions at 1056; see Louis L. Jaffe, Judicial Control of Administrative Action 694-97 (1965). We believe this sliding scale measures substantially in SWBT's favorthe company's claimed statutory rights are clearly exposed to extinction by the preliminary order as discussed above, resulting "in a less stringent requirement of certainty of victory" after trial on the merits.
In any case, SWBT is required to show only "that a bona fide issue exists as to [the company's] right to ultimate relief" by *31 way of declaratory judgment, mandamus, or permanent injunction. 6 Hamilton Lowe Remedies § 153, at 188 (Texas Practice 2d ed.1973); see Reasoner, at 411. We believe the record certainly demonstrates such a bona fide issue as to SWBT's claimed statutory rights and the PUC's alleged want of jurisdiction.
The following propositions are beyond dispute: The PUC is a subordinate body that derives all its powers from the legislature and exercises those powers subject to legislative control. See City of El Paso v. Public Util. Comm'n, 584 S.W.2d 545, 547 (Tex.Civ.App.Austin 1979, no writ). And where the legislature qualifies a delegated power by specifying a method for its exercise, "[t]he prescribed method excludes all others, and must be followed." Cobra Oil & Gas Corp. v. Sadler, 447 S.W.2d 887, 892 (Tex.1968); see also Foster v. City of Waco, 113 Tex. 352, 255 S.W. 1104, 1105 (1923). "An administrative agency ... is a creature of statute and must live within the statutes" entrusted to its administration. Balios v. Tex. Dept. of Pub. Safety, 733 S.W.2d 308, 311 (Tex. App.Amarillo 1987, writ ref'd). And "[i]t lies within the judicial power ... to say with final authority what a statute means." Amarillo Indep. Sch. Dist. v. Meno, 854 S.W.2d 950, 955 n. 6 (Tex.App.Austin 1993, writ denied).
As we understand the record, SWBT contends its unquestioned compliance with PURA sections 58.054 (arresting the company's switched-access charges at the 1995 amount), and 58.301 .302 (providing for incremental reductions of the 1995 amount) gives the company a statutory right to charge the resulting current amount for switched-access service. The effect of these statutes, SWBT contends, is to deprive the PUC of the power to suspend in whole or in part the statutory reductions or the current amount, find circumstances in which they do not apply in whole or in part, or reduce them for any reason or purpose, all under the authorities set forth above. We believe the PUC's preliminary order indicates clearly that the agency claims a power to take one or more of these actions, leaving the issue to be whether the agency's delegated powers include authority to take any such substantive action.
SWBT contends in addition that the orchestrated effect of PURA sections 58.054, 58.301, and 58.302 is to deprive the PUC of any power to conduct an administrative hearing for the purpose of reviewing or modifying the amount of switched-access charges resulting from SWBT's undisputed compliance with those statutes. SWBT gives two reasons for this contention. First, the validity of these statutes is not challenged; and, because the legislature has therein exercised its residual power to fix the amount an electing company such as SWBT may charge for its switched-access service, by specified one-cent and two-cent reductions at stated intervals, these statutes necessarily exclude any power in the PUC to do so. SWBT therefore concludes the PUC lacks authority to conduct a hearing questioning the validity of the resulting amount for any regulatory purpose, just as the agency lacks jurisdiction to conduct a hearing for the purpose of questioning the amount of switched-access charges fixed by the Federal Communications Commission for SWBT's interstate connections. The amount of SWBT's charges is therefore binding as a matter of law on the PUC, SWBT, and all others subject to the general laws, until the statutes mentioned are modified by the legislature itself.
Second, SWBT contends PURA section 58.025(a) expressly forbids the PUC to entertain a complaint, conduct a hearing, or make "any determination regarding the *32 reasonableness of the company's ... rates."[8] The hearing required by the preliminary order is of that prohibited character, SWBT contends, as opposed to a permissible hearing regarding "the company's implementation and enforcement of a competitive safeguard required by Chapter 60" of PURA, as stated in PURA section 58.025(b). SWBT reasons thusly: The reasonableness of SWBT's 1995 switched-access charges was established when the amount thereof was approved originally by the PUC and validated afterwards when the legislature fixed the 1995 amount as the minuend from which the incremental reductions required by PURA sections 58.301 and 58.302 were subtracted to arrive at the amount SWBT currently charges for switched-access service. When the PUC undertakes to conduct a hearing to review and perhaps revise the current amount by further reductions, in SWBT's view the agency is actually subjecting the 1995 amount to a hearing because the current amount is no more than the 1995 amount as reduced by the legislature in PURA sections 58.301 and 58.302. Stated another way, the 1995 amount is the only amount that could possibly be questioned by the PUC because the reductions made therefrom were mandated to the penny by legislative enactments to which the PUC owes obedience; and PURA section 58.025(a) expressly forbids a hearing in which the reasonableness of the 1995 amount might be questioned.
This is, in our view, not an unreasonable interpretation of the statutes in question. The correctness of that interpretation is not, of course, before us in the present appeal. We note in passing, however, that denying SWBT's application for temporary injunction certainly does not preserve the status quo insofar as SWBT's claimed right to a statutory exemption from an agency hearing is concerned. Rather, the denial of SWBT's application, in the present circumstances, is in effect a decision on the merits that the right does not exist or, if it does, the PUC may lawfully extinguish it in the interim before trial.
The PUC and AT & T raise several arguments against the likelihood SWBT will prevail after a trial on the merits. They point first to PURA section 58.025(b). That statute states expressly that an electing company's statutory exemption from a hearing as to the reasonableness of its rates "does not prohibit a... hearing or determination on [the company's] implementation and enforcement of a competitive safeguard required by Chapter 60" of PURA. These safeguards are implicit in several provisions found in Chapter 60. In general, they forbid the charging of rates that are discriminatory, anti-competitive, unreasonably preferential, prejudicial, unjust, or unfair.[9] To the *33 extent any of these competitive safeguards may ultimately be shown to apply to the present controversy, we believe they are simply issues, aspects, or elements of a bona fide dispute between the parties involving complicated issues of statutory construction in matters of importance to all the parties. In this connection, we note the following observations:
[O]ur system of procedure is such that legal rights cannot be finally determined upon a hearing relating to the wisdom or expediency of issuing a status quo order. Deliberate action is essential for the accurate determination of legal rights and upon occasion this can be secured only by issuing a temporary decree protecting a status quo.
Southwest Weather Research, Inc. v. Jones, 160 Tex. 104, 327 S.W.2d 417, 421 (1959); see, e.g., Johnson v. Austin, 674 S.W.2d 894, 899-900 (Tex.App.Austin 1984, no writ); Baucum v. Texam Oil Corp., 423 S.W.2d 434, 440-41 (Tex.Civ. App.El Paso 1967, writ ref'd n.r.e.); Long v. Employers Cas. Co., 392 S.W.2d 161, 162 (Tex.Civ.App.Waco 1965, no writ). In other words, the legal or factual issues of a case may themselves dictate that an accurate assessment and determination of legal rights can be secured only by a temporary injunction. We believe that is the case here where the controversy involves competing public interests and policies, the delicate relationship of court and agency, and a possible need to harmonize the provisions of a complicated statutory system. See, e.g., Lumberton Mun. Util. Dist. v. Cease, 596 S.W.2d 601, 603 (Tex.Civ.App.Beaumont 1980, no writ).
We cannot see that any of the various statutory powers of the PUC clearly negate SWBT's claims and statutory-construction arguments. If they do have that effect in the end, it will only be by way of judicial construction of all the pertinent statutes in context. The dispute is, in other words, bona fide as to the PUC's jurisdiction and SWBT's claimed statutory rights.
AT & T and the PUC raise certain other contentions, apart from issues of statutory construction, in support of their position that SWBT has not shown a likelihood of prevailing after trial on the merits. They assert first that SWBT's lawsuit is premature because the company has not exhausted its administrative remedies. We believe the exhaustion doctrine is not applicable here. The doctrine is subject to several exceptions. It does not apply, for example, when the agency's jurisdiction is questioned, as it is here, on persuasive grounds. See, e.g., City of Sherman v. Public Util. Comm'n, 643 S.W.2d 681, 683 (Tex.1983); Jaffe at 515. AT & T contends also that the primary-jurisdiction doctrine defeats any likelihood that SWBT will prevail after trial on the merits. This doctrine ensures that administrative agencies are not circumvented on issues that have been committed to them by statute for an original decision. See Gregg v. Delhi-Taylor Oil Corp., 162 Tex. 26, 344 S.W.2d 411, 413-14 (1961); Jaffe at 121. Applicability of the doctrine depends upon whether a particular power has been delegated to the agency. We believe SWBT has raised a bona fide issue concerning whether the legislature has delegated to the PUC a power to reduce further SWBT's switched-access charges or a power to conduct a hearing to inquire in that regard. Consequently, neither the exhaustion nor the primary-jurisdiction doctrine necessarily or clearly precludes *34 any likelihood that SWBT will prevail after trial on the merits.
AT & T and the PUC contend finally that judicial interference with the agency proceeding is prohibited because the hearing itself is within the PUC's various regulatory powers even if the agency lacks jurisdiction to grant a particular remedy, such as a further reduction of SWBT's switched-access charges to prevent their having an anti-competitive or discriminatory effect. See Texas Educ. Agency v. Cypress-Fairbanks Indep. Sch. Dist., 830 S.W.2d 88, 90-91 (Tex.1992). We believe Cypress-Fairbanks is plainly distinguishable. The Court held in that case that the statutory authority delegated to the Commissioner of Education included authority to consider the claims of school employees at least for some purposes, even if the Commissioner was powerless to finally adjudicate those claims or grant full relief in the form of money damages or injunctive relief. See id. In contrast, SWBT has shown a bona fide dispute regarding whether the PUC is entirely without power to reduce further the company's switched-access charges for any purpose, and contends indeed that the legislature has withdrawn the matter of the amount of such charges from the PUC's authority for all purposes, save enforcement of the residue left after SWBT's undisputed compliance with PURA sections 58.054, 58.301, and 58.302.
Two factors remain to be considered regarding the grant or denial of the temporary injunction for which SWBT applied: (1) the public interest and (2) the matter of comparative injury, that is to say, a balancing of the "equities" and hardships attending one course or the other. See General Tire & Rubber Co. v. Texas Pac. Coal & Oil Co., 102 S.W.2d 1086, 1089 (Tex.Civ. App.Fort Worth 1937, writ ref'd).
The public interest is not necessarily in the solution adopted by the agency.... [T]he public interest is often identified with settling an issue right rather than settling it quickly.... The evaluation of the public interest factor upon [application] for a stay impliedly poses the question whether the public interest requires that the individual be harmed before the legality of that harm is established.
Jaffe at 693. No public-interest factor has been brought to our attention, and we are unable to imagine one, which requires that SWBT's claimed statutory rights must be extinguished before a trial on the merits is held to determine that such destruction is within the PUC's delegated powers and therefore a lawful destruction. SWBT's claimed statutory rights are unquestionably exposed to that destruction by reason of the PUC's preliminary order; the PUC and AT & T are faced only with delay before their asserted interests in competitive, nondiscriminatory, just, and fair rates are vindicated by a trial on the merits, should that be the district-court judgment. We believe, therefore, that the public-interest factor and the factor of comparative injury weigh heavily in favor of SWBT.
For the reasons given, we believe the record shows on undisputed facts that SWBT has clearly raised a bona fide issue as to its right to recover on its claims after a trial on the merits; and, there is no basis in the record from which a contrary inference might reasonably be drawn. We are compelled then to hold the district court abused its discretion by failing to apply the law correctly to the undisputed facts. See Southland Life Ins. Co. v. Egan, 126 Tex. 160, 86 S.W.2d 722, 723 (1935).
We remand the cause to the district court for issuance of a proper temporary injunction consistent with our opinion. We point out in this connection that where an injunction is proper, as it is here, "it must *35 be drawn with such specificity so as to remedy only the particular harm complained of; an injunction drawn too broadly" is improper. 2 Am.Jur.2d Administrative Law § 552, at 543 (2000). By this, we mean the contested case may proceed in the PUC for purposes unrelated to the validity of SWBT's current switched-access charges.

Gammel, The Laws of Texas 1879-1889, at 3, 3 (Austin, Gammel Book Co. 1898) (since repealed); Abner Eddins Lipscomb, Judicial Control of Administrative Action in Texas, The Baylor Bulletin, Law Number, at 10 (1938).
[5]  PURA section 14.053 directs that the utility division of SOAH "shall conduct each hearing in a contested case that is not conducted by one or more commissioners." Texas Government Code section 2001.003(1) defines "contested case"; section 2001.058 outlines the procedures governing contested cases conducted by SOAH; and, section 2001.062 contains provisions governing the proposal-for-decision practice in such cases.
[6]  In the present context, the word "jurisdiction" refers to an administrative agency's power to hear and determine issues of fact and law and to carry into effect any resulting agency decision. See In re N.J.A., 997 S.W.2d 554, 559 (Tex.1999); Stauffer v. City of San Antonio, 162 Tex. 13, 344 S.W.2d 158, 161 (1961). Being a statutory creature without inherent power, the PUC has only those powers delegated to it in a valid statute. See Sexton v. Mount Olivet Cemetery Ass'n, 720 S.W.2d 129, 137 (Tex.App.Austin 1986, writ ref'd n.r.e.).
[7]  Section 15(a) of the 1961 Model State Administrative Procedure Act, from which the Texas Administrative Procedure Act is largely derived, provides that "[a] preliminary, procedural, or intermediate agency action or ruling is immediately reviewable [by a court] if the final agency decision would not provide an adequate remedy." Revised Model State Administrative Procedure Act § 15(a), 14 U.L.A. 430 (1961); see Tex. Gov't Code Ann. § 2001.001 et seq. (West 2000). The provision was eliminated from the Texas act "at the request of several major agencies concerned that intermediate appeals could unreasonably delay final administrative action" and because it was difficult to imagine a case where the final agency action would not provide an adequate remedy. Dudley McCalla, The Administrative Procedure and Texas Register Act, 28 Baylor L.Rev. 445, 462 (1976). Deletion of the model-act provision necessarily refers the matter to the reviewing court's equity power.
[8]  The word "rates" includes switched-access charges. See PURA § 11.001(15)(A) (West 1998).
[9]  See PURA § 60.001 (PUC must "ensure that the rates and rules of an incumbent local exchange company: (1) are not unreasonably preferential, prejudicial, or discriminatory"; and (2) that "they are applied equitably and consistently"); PURA § 60.002 (vests "exclusive jurisdiction" in the PUC "to implement competitive safeguards" to achieve those objectives and states explicitly that PURA "[s]ection 58.025 does not prevent the [PUC] from enforcing" Chapter 60); PURA § 60.061 (requires the PUC to "adopt rules governing imputation of the price of a service," defining "imputation" as "a regulatory policy the commission shall apply to prevent an incumbent local exchange company from selling a service or function to another telecommunications utility at a price that is higher than the rate the incumbent local exchange company implicitly includes in services it provides to the company's retail customers"); PURA §§ 60.001, .002, .061 (West 1998). Section 60.063 of PURA provides that the PUC "shall impute the price of switched access service to the price of each service for which switched access service is a component until switched access service is competitively available." Id. § 60.063.
