Opinion
TIMLIN, Acting P. J.
The underlying action to which this writ petition relates is a mandamus and a declaratory and injunctive relief proceeding brought by Temecula Ranchos against the County of Riverside (County), in which Temecula Ranchos challenges County’s approval of a residential [834]*834housing project on the basis that County improperly determined that the project will not have a significant effect on the environment and issued a negative declaration to that effect as to the project. The question presented by the petition filed in this court is whether Temecula Ranchos complied with the statutory requirements for service of its petition for administrative mandamus under Public Resources Code section 21167 (petition) contained in Public Resources Code section 21167.6, subdivision (a).1 We conclude that the latter section of the Public Resources Code does establish the procedure for obtaining jurisdiction over County in the underlying action, but that the failure to personally serve the petition on County within the specified period was not fatal to Temecula Ranchos’s action.
I
Procedural History of the Underlying Action
The procedural history of the underlying action is not subject to dispute. County filed the negative declaration on January 28, 1993, and posted notice on January 29. On February 25, 1993, Temecula Ranchos gave written notice to County of its intent to commence the action, and then filed its petition on February 26, 1993. On March 3,1993, Temecula Ranchos served County with conformed copies of the summons2 and petition, the “Notice of Commencement,” and a “Request for Preparation of Record of Proceedings.” This service was made by mail and there is no contention that it [835]*835complied with any of the substituted service provisions of the Code of Civil Procedure.3
Temecula Ranchos then filed an amended petition on March 23. This petition was personally served on County on March 29, and there is no contention that this service did not comply with the personal service requirements of the Code of Civil Procedure. On April 29, County moved to quash service of “summons,” which motion was directed to the purported service of the petition on March 3,1993. It also moved to dismiss the action.4 (Code Civ. Proc., § 418.10.) It argued that as to California Environmental Quality Act actions commenced under Public Resources Code section 21167, subdivision (b), Public Resources Code section 21167.6(a) sets a 10-business-day time limit for personal service of the petition, which time limit is jurisdictional. As Temecula Ranchos had not accomplished proper service on County within this period, County claimed that it was entitled to a dismissal. Presumably County intended that the court should also quash the second service made on March 29 as untimely, although the motion was not entirely clear on the requested relief.
In response, Temecula Ranchos argued that section 21167.6(a) is a statute governing notice, not jurisdiction, and that under the service provisions of the Code of Civil Procedure its personal service of the amended petition on March 29 was both timely and effective for jurisdictional purposes.
The trial court found that the service requirement of section 21167.6(a) was not jurisdictional, thus agreeing with Temecula Ranchos. Accordingly, it denied County’s motion and this petition followed.

Discussion
A. General Principles Applicable in Interpreting CEQA Statutes
The specific issue before us is whether Public Resources Code section 21167.6(a) provides the exclusive service procedure by which a [836]*836petitioner under section 21167 acquires jurisdiction over a public agency, or whether it serves only a notice function and does not supersede the general provisions of the Code of Civil Procedure with respect to service and the time limits within which it must be accomplished.
It is axiomatic that if statutory “language is ... . clear and unambiguous there is no need for construction.” (In re Lance W. (1985) 37 Cal.3d 873, 886 [210 Cal.Rptr. 631, 694 P.2d 744].) In our view, the statute under consideration is not unequivocal as to service of the petition and the method thereof on the public agency so as to have caused the trial court to have jurisdiction over the agency. Thus, we attempt to “ascertain the intent of the Legislature so as to effectuate the purpose of the law.” (Estate of MacDonald (1990) 51 Cal.3d 262, 268 [272 Cal.Rptr. 153, 794 P.2d 911].) In so doing, we strive to reach a reasonable result and to avoid absurdities. (In re Eric J. (1979) 25 Cal.3d 522, 537 [159 Cal.Rptr. 317, 601 P.2d 549].) In this case, neither of the proposed interpretations by the parties is absurd or unreasonable, and the intent of the Legislature cuts both ways.
We begin our analysis with observations concerning the overall purpose and structure of the California Environmental Quality Act (CEQA or Act), Public Resources Code section 21000 et seq. Temecula Ranchos points out that CEQA was obviously designed and enacted with the intent to protect the environment, and that it has often been interpreted to provide as wide a protection as possible. The Supreme Court has repeatedly confirmed that CEQA is “ ‘to be interpreted in such manner as to afford the fullest possible protection to the environment within the reasonable scope of the statutory language.’ ” (Laurel Heights Improvement Assn. v. Regents of the University of California (1988) 47 Cal.3d 376, 390 [253 Cal.Rptr. 426, 764 P.2d 278], quoting Friends of Mammoth v. Board of Supervisors (1972) 8 Cal.3d 247, 259 [104 Cal.Rptr. 761, 502 P.2d 1049].)
However, while these precepts are validly applied to the substantive merits of challenges brought under CEQA, in which it is asserted that certain projects will or may have a significant effect on the environment, that does not mean that the same standard of liberality should necessarily be applied in interpreting the procedural requirements of the Act. The Act contains a number of provisions evidencing the clear “legislative determination that the public interest is not served unless challenges under CEQA are filed promptly” (Oceanside Marina Towers Assn. v. Oceanside Community Development Com. (1986) 187 Cal.App.3d 735, 741 [231 Cal.Rptr. 910]), and the same policy must certainly be said for similar provisions which require that a CEQA action, once filed, be diligently prosecuted and heard as soon as reasonably possible.
[837]*837Thus, Public Resources Code section 21167 establishes statutes of limitations governing various CEQA challenges; these statutes run from 30 to 180 days—periods of far shorter duration than the typical civil statute of limitations controlling common civil actions. (Cf. Code Civ. Proc., §§ 337, subd. 1—four years on written contract, 338, subd. (b)—three years for trespass or injury to real property, 340—one year for personal injuries.) Public Resources Code section 21167.8, subd. (a) requires that a settlement conference be scheduled within 20 days after the petition is served, and held within 45 days of service. Public Resources Code section 21167.4 requires the petitioner in a CEQA proceeding to request a hearing on the petition within 90 days of its filing, or be subject to dismissal, while section 21167.1 gives a general trial preference to CEQA actions over all other civil actions. Patently, there is legislative concern that CEQA challenges, with their obvious potential for financial prejudice and disruption, must not be permitted to drag on to the potential serious injury of tiie real party in interest. Recognizing this potential for abuse, in Citizens of Goleta Valley v. Board of Supervisors (1990) 52 Cal.3d 553 [276 Cal.Rptr. 410, 801 P.2d 1161], the court, while repeating the language from Laurel Heights quoted above, also cautioned that CEQA was not to be “subverted into an instrument for the oppression and delay of social, economic, or recreational development and advancement.” (At p. 576.)
Inevitably, however, the policy of encouraging environmental protection through the statutory mechanisms for challenging allegedly improper actions sometimes conflicts with the short times limits of CEQA and the policies served by such limits.
Where the law is clear, these strict requirements of CEQA are applied as written; in Lee v. Lost Hills Water Dist. (1978) 78 Cal.App.3d 630, 633-634 [144 Cal.Rptr. 510], for example, the court held a petition untimely even though the petitioner landowners asserted that they had never received notice of the action they wished to challenge.5 In Oceanside Marina Towers, supra, the petitioners argued that the short period of section 21167, subdivision (b) did not bar their apparently tardy petition because the notice of negative declaration had been posted by the respondent city, rather than the redevelopment agency which was actually the “lead agency” in the project (see Pub. Resources Code, § 21067); the court found that as the city and the agency were essentially the same, the statute had begun to run at the time of posting, and the action was barred.
Nevertheless, it appears that, under certain circumstances, the courts have construed the unique procedural requirements of CEQA so as to permit the [838]*838maintenance of a challenge for noncompliance with CEQA despite some arguable failure by the petitioner to fulfill the Act’s procedural requirements for the maintenance of such a suit, or the proffering of a colorable construction unfavorable to the petitioner. In Concerned Citizens of Costa Mesa, Inc. v. 32nd Dist. Agricultural Assn. (1986) 42 Cal.3d 929, 939 [231 Cal.Rptr. 748, 727 P.2d 1029], the court was faced with a situation in which the responsible public agency had duly prepared an environmental impact report, but then had approved substantial changes to the project without any notice to surrounding landowners. The landowners had not filed suit within the allowed 180-day period in which to attack a project after its commencement. However, the court permitted the action to proceed based on the assertion that the changes had not been reasonably apparent during the statutory period. It interpreted the apparently clear language6 limiting challenges to a filing period of 180 days following commencement of a project, to provide an actual limitations period of 180 days running from the time in which the substantial changes to the project reasonably became apparent. In so holding, the court repeated the language from Friends of Mammoth quoted above, stressing the importance of interpreting CEQA statutes to give the “fullest possible” protection.
In Concerned Citizens of Costa Mesa, Inc., the interpretation of Public Resources Code section 21167, subdivision (a) applied by the court was necessary to prevent an obvious injustice, as well as to discourage public agencies from similarly attempting to hide changes in approved projects and then claiming invulnerability from suit based on the short limitations period. Here, no factor of impropriety works against County and in favor of Temecula Ranchos. However, in other reported cases the courts have adopted interpretations favorable to petitioners when reasonable alternatives were proposed, and even where the petitioners have been at fault.
First, in Citizens of Lake Murray Area Assn. v. City Council (1982) 129 Cal.App.3d 436, 440-441 [181 Cal.Rptr. 123], the court held that the 30-day period established by Public Resources Code section 21167, subdivision (b) did not actually start to run until notice of the adoption of a negative declaration was posted—although, as in Concerned Citizens of Costa Mesa, Inc., the statutory language was apparently clear in providing for an earlier triggering date, that is, upon filing of the notice alone. In Mitchell v. Orange County (1985) 165 Cal.App.3d 1185, 1192 [211 Cal.Rptr. 563], the court rejected the respondent County’s argument that Public Resources Code section 21167.4, which requires a petitioner to “request a hearing within 90 days of filing the petition” meant that the hearing had to be conducted or set within that period; the court held that the statute only obligated the petitioner [839]*839to make the request within 90 days, not to see that the petition was actually calendared within that period. Finally, in McCormick v. Board of Supervisors (1988) 198 Cal.App.3d 352, 359-362 [243 Cal.Rptr. 617], the court held that a petitioner who failed to make the necessary request under section 21167.4, and who therefore suffered a mandatory dismissal, could nevertheless rely on Code of Civil Procedure section 473 in seeking relief from the dismissal.
In attempting to reconcile the two public policies, we conclude that if a statute is clear on its face and operates fairly, its unambiguous terms must prevail even if the result is to bar a CEQA challenge. (Lee, supra, 78 Cal.App.3d 630; Oceanside Marina Towers, supra, 187 Cal.App.3d 735.) However, if even a facially clear statute operates unfairly or might encourage deception, it should be construed in favor of the challenger. (Concerned Citizens of Costa Mesa, supra, 42 Cal.3d 929.) If reasonable minds may differ on the meaning of a CEQA provision or its application in light of other statutory provisions, any such conflicts and questions should be resolved in a manner which permits the challenge under CEQA to proceed. (McCormick, supra, 198 Cal.App.3d 352; Mitchell, supra, 165 Cal.App.3d 1185.)
B. Interpretation of Section 21167.6(a) Regarding Service of the Petition
Neither party appears to disagree with the principle that, for the purposes of obtaining personal jurisdiction and consistent with constitutional due process, service of a petition for an administrative writ of mandate must be in the same manner required for any civil action.
In fact, the statutes are far from clear. Code of Civil Procedure section 1107, which specifically governs service of writ petitions, states that if an application is made for the issuance of an alternative writ, “. . . the application shall be accompanied by proof of service of a copy thereof upon the respondent and the real party in interest named in such application. The provisions of Chapter 5 (commencing with Section 1010) of Title 14 of Part 2 shall apply to the service of the application.” Section 1010 et seq. governs service of motions, and expressly permits simple service by mail as an alternative to personal service. (Code Civ. Proc., § 1012.) Thus, such service would presumably be sufficient if an alternative writ were sought.
However, Code of Civil Procedure section 1107 goes on to provide that if no alternative writ is sought, and the petition will be set for hearing, “. . . the action may be filed and served in the same manner as an ordinary action under Part 2 (commencing with Section 307).” Further muddying the issue is Code of Civil Procedure section 1016, which expressly provides that the more liberal service of notice provisions do not apply “to the service of a [840]*840summons or other process, or of any paper to bring a party into contempt.” This statute’s reference to contempt proceedings confirms the Legislature’s intent that, as a rule, specific service procedures are necessary to establish jurisdiction in a mandate proceeding where an alternative writ is not sought. In other words, the statutes first appear to authorize acquisition of jurisdiction by “notice-service” if an alternative writ is sought; however, the statutes to which reference is made caution that such service is not sufficient to confer jurisdiction! The use of “may” in authorizing a party who does not seek an alternative writ to use the more formal service procedures applicable to commencing any civil action (e.g. Code Civ. Proc., § 412.10 et seq.) indicates a discretionary authorization; however, why would a petitioner elect to follow the more difficult procedures if notice-service was permissible for obtaining jurisdiction?
The confusion (which may exist only in our minds) may be cleared up by an examination of Code of Civil Procedure section 1096, which provides that a writ, including an alternative writ, must be served in the same manner as a summons in a civil action. Thus, although notice-service of the application is sufficient under Code of Civil Procedure section 1107 to obtain the alternative writ, personal service of an alternative writ is necessary before a trial or hearing can be had. In our view, the apparently optional use of the Code of Civil Procedure service of process procedures authorized by section 1107 for mandate proceedings where no alternative writ is sought, is in fact mandatory. At one stage or another, personal service of either the alternative writ or the petition must be made.7
Although the opinion in Younger v. Jordan (1954) 42 Cal.2d 757 [269 P.2d 616] does not discuss section 1107, we think the reminders therein are [841]*841instructive. In that case, the court declined to rule on a petition because the real party had not been given notice either by personal service “or some form of substituted service which is authorized by law,” referring to Code of Civil Procedure section 410 et seq. It is true that due process does not necessarily require that jurisdiction be obtained by personal service, even within a state. (See Mulleme v. Central Hanover Bank (1950) 339 U.S. 306, 314-315 [94 L.Ed. 865, 873-874, 70 S.Ct. 652].) However, California has traditionally required personal service unless it is not possible after the exercise of due diligence. With the foregoing discussion in mind, we do accept the parties’ implicit agreement that such service was necessary here for jurisdictional purposes.
County’s position is that Public Resources Code section 21167.6(a), being a jurisdictional statute, causes Temecula Ranchos’s failure to personally serve the petition on it within the time limits of the statute to be fatal.
County relies on the language in the opening paragraph of Public Resources Code section 21167.6(a) to the effect that its provisions shall govern “notwithstanding any other provision of law.” As set forth in footnote 1, ante, section 21167.6 contains several distinct provisions. Although it is not at all obvious that the general proviso was designed cancel out any specific statute, we agree that the provisions of section 21167.6 must prevail over directly contradictory provisions in other statutes. For example, Code of Civil Procedure section 1094.6, subdivision (c) gives a public agency 90 days in which to prepare the administrative record relevant to most administrative mandamus proceedings. Obviously, subdivision (b) of Public Resources Code section 21167.6, which requires preparation in 60 days, controls in CEQA matters.
Public Resources Code section 21167.6, subdivision (a), however, contains arguably two severable provisions, one relating to the filing of a request that the public agency prepare the administrative record, and the other to the service of the request and petition on the agency. Consequently, the subdivision as a whole does not have a direct counterpart over which it prevails. The subdivision requires the petitioner to file (presumably with the court) a request that the local agency prepare the administrative record. “The request, together with a copy of the petition, shall be served upon the public agency not later than 10 business days after the action is filed.”8 Subdivision (b) sets out the time limits for preparing the record, but also provides alternatives to the preparation by the local agency—for example, the [842]*842petitioner may elect to prepare the record itself. In such a case, of course, a “Request to Prepare” under subdivision (a) would not be necessary. It is far from obvious that subdivision (a), which includes service of the petition itself almost as an afterthought to the service of the “Request to Prepare,” was intended to provide the exclusive basis for service of the petition in a jurisdictional sense. The copy of the petition could just as reasonably be considered as essential to ensure that the local public agency knows what record is to be prepared.
The counter to this argument, which we find of considerable weight, is that the need for notice by the public agency of an impending CEQA attack under Public Resources Code section 21167 is already satisfied by section 21167.5, which requires the petitioner to serve by mail notice of the (intended) commencement of the action even before it is filed. This notice must identify the project being challenged. After receipt of that notice, the local agency would then know what record should be prepared when it received the “Request to Prepare.” Under this view, the copy of the petition is not necessary to provide notice, and the requirement that it be served with the “Request to Prepare” may logically be viewed as referring to jurisdictional service.9
This conclusion is buttressed by the fact that a petitioner or plaintiff in a CEQA action is limited to those issues which were raised by objections in administrative proceedings or at similar hearings before the public agency. (Pub. Resources Code, § 21777; Browning-Ferris Industries v. City Council (1986) 181 Cal.App.3d 852, 859 [226 Cal.Rptr. 575].) Even if a public agency tentatively determines to issue a negative declaration, notice must be given and interested parties must be provided an opportunity to comment. (Pub. Resources Code, § 21092.)
Thus, a public agency does not need to see a copy of the petition in order to know what issues may be raised; although a CEQA petitioner or plaintiff may eliminate issues in its CEQA action, the public agency cannot be surprised by the addition of new objections. The service required by Public Resources Code section 21167.6 would be redundant if viewed as “mere notice.”
County therefore argues (by implication, at least) that the “other provision of law,” which does not apply with respect to service, is Code of Civil Procedure section 583.210, subdivision (a), which sets an outer limit of three years for service of a summons and complaint in a civil action.
The position of Temecula Ranchos is in part reflected in the discussion in part II A, ante. It relies both upon the public interest in CEQA compliance and the public interest in speedy resolution by arguing that the service [843]*843requirements under discussion are intended merely to “facilitate” litigation and to provide prompt notice, while also contending that the failure to comply with such requirements does not result in a forfeiture of personal jurisdiction.
Temecula Ranchos argues that it would be unreasonable to require jurisdictional service within 10 business days of the filing of a petition. However, in light of the expedited procedures set forth in the Act, and in part detailed above, we do not agree that the Legislature could not logically have established an exceptionally short time in which to perfect service. It is to be noted that service on a public agency rarely presents the difficulties sometimes encountered in finding and personally serving an individual; the designated representatives for service (see Code Civ. Proc., § 416.50, subdivision (a)) may be assumed to be easy to find. Thus, service within 10 business days should in most cases be neither burdensome nor impracticable.
We observe that Temecula Ranchos’s position requires the acceptance of one significant anomaly. Public Resources Code section 21167.6(a) requires service of a copy of the petition. If this is not jurisdictional service, what is the point of requiring duplicative notice-service within a short time span? Even if we were to agree that Code of Civil Procedure section 583.210, subdivision (a) governs, and allows a CEQA petitioner three years in which to achieve service, it is obvious that this lengthy time period is illusory because the time limits contained in CEQA itself compel jurisdictional service, if not within 10 business days, then at least within no more than a few weeks.10 Under Temecula Ranchos’s arguments, a CEQA petitioner must give notice of commencement of the action, then within 10 business days of filing the petition serve a “notice” copy of the petition, and then within no more than a few more weeks formally serve another copy of the petition to acquire jurisdiction. But if this is the case, either the section 21167.6 service is redundant as notice-service following the required notice under Public Resources Code section 21167.5, or a further, jurisdictional [844]*844service must follow swiftly upon the heels of the section 21167.6 service. We decline such a construction; we think it more reasonable not to assume that the Legislature intended to promulgate unnecessary blizzards of paperwork.11 Finally, we reject any contention that the Legislature’s use of the unqualified term “served” rather than “personally served” in section 21167.6 positively reflects an intent that such service is not designed for jurisdictional purposes. Although “personal service” does, of course, confer personal jurisdiction, it is not the only means by which such jurisdiction may be obtained. Where the statutory conditions are met, such jurisdiction is also conferred by substituted service, mailed service, or even service by publication. (See Code Civ. Proc., §§ 415.10-415.50.) Thus, the Legislature could not have used the term “personally served” to indicate jurisdictional service, because the term would have been improperly limited. Conversely, the absence of the word “personally” is not an indication that jurisdictional service is not intended.
In Whitman v. Board of Supervisors (1979) 88 Cal.App.3d 397, 404 at fn. 2 [151 Cal.Rptr. 866], the court held that the prefiling notice required by section 21167.5 was not jurisdictional and that failure to comply did not compel dismissal. The court also relied on the fact that the petitioner in that case had substantially complied with the requirement, so that no prejudice existed. However, Whitman, while consistent with those cases cited above which adopt liberal constructions of CEQA provisions in favor of a petitioner, is not persuasive with respect to a statutory requirement for service of the petition itself.
We conclude that Public Resources Code section 21167.6(a), read in light of the numerous other CEQA procedural provisions which require prompt prosecution and encourage speedy resolution of CEQA matters, does include the requirement for jurisdictional service of the petition in CEQA proceedings. Temecula Ranchos did not accomplish personal service (or any acceptable alternative method of service) of the petition on March 3, 1993. The service by mail did not conform to the requirements of Code of Civil Procedure sections 415.20 or 415.30. The statutory requirement for jurisdictional service, therefore, was not satisfied.
This conclusion does not, however, lead automatically to the further result that County was entitled to have the purported services of the petition quashed and the action dismissed. Although the service is “jurisdictional” in [845]*845the sense that it is intended to obtain and confer personal jurisdiction over the defendant, thereby enabling Temecula Ranchos to prosecute the action against the County, it is not “jurisdictional” in the sense that the court is deprived of the power to proceed if service is not timely completed in accordance with the statute.
As recounted above, Temecula Ranchos did personally serve its amended petition on County on March 29, 1993.12 County argues that this was too late, and that the “window” for obtaining jurisdiction was closed. We disagree.
In general civil actions, service of summons must be made within three years. (Code Civ. Proc., § 583.210, subd. (a).) Failure to do so results in a mandatory dismissal of the action. (Id., § 583.250.) The same time limit/mandatory dismissal coupling has been enacted to cover the failure to bring a civil action to trial or retrial within the specified periods. (Id., §§ 583.310-583.320, 583.360.)
Similarly, Public Resources Code section 21167.4 provides that if the petitioner does not request a hearing within 90 days of filing a CEQA petition, the petition is “subject to dismissal.” The statute has been construed as mandatory.13 (San Franciscans for Reasonable Growth v. City and County of San Francisco (1987) 189 Cal.App.3d 498, 503 [234 Cal.Rptr. 527].) A petitioner’s failure to participate in the settlement procedure also justifies dismissal unless good cause is shown. (Pub. Resources Code, § 21167.8, subd. (g).)
By contrast, no comparable statutory provision provides for a mandatory or discretionary dismissal by the court for the failure of petitioner to perfect service of the petition within the period prescribed by section 21167.6(a). We find this absence significant.
Code of Civil Procedure section 583.250, of course, mandates dismissal only for failure to comply with the article of which it is a part. As Public [846]*846Resources Code section 21167.6(a) is not a part of that article, strict statutory construction requires the assumption that mandatory dismissal of the instant action for administrative mandamus, and declaratory and injunctive relief is not an available remedy. If the Legislature intends that the failure to comply with a specific and unusually short provision for service of process in a particular action shall result in an automatic dismissal, presumably it knows how to say so.
For example, Code of Civil Procedure section 863 requires that publication of summons in a quasi-validation action must be made within 60 days after the complaint is filed. Failure to do so requires dismissal, unless good cause is shown. However, this provision, with its discretionary exception, appears to recognize that the short period prescribed for service may cause hardship and inequity. (See City of Ontario v. Superior Court (1970) 2 Cal.3d 335, 342 [85 Cal.Rptr. 149, 466 P.2d 693], in which the court remarked that the strict time limits of the validation statutes imposed a “heavy burden” even on a “vigilant taxpayer.”) Presumably, if the Legislature felt that a period of 60 days in which to achieve service might operate unreasonably or unfairly in some cases, it could consistently have believed that a period of 10 business days for jurisdictional service of a CEQA petition, while a salutary encouragement to the expedition of such actions, should not be rigidified into drastic effect by the remedy of dismissal.14 Nor do we believe it justifiable to assume that the omission of such a provision was a mere legislative oversight. It is to be noted that subdivision (b) of Public Resources Code section 21167.6 requires, in similarly “mandatory” terms, that the public agency shall prepare the administrative record within 60 days of notification. However, the statute is silent as to the consequences of the agency’s failure to do so. We assume that County would disagree with the position that a local agency which failed to comply would be subject to automatic default, and, in our view, that remedy would be too severe. In this case, County argues for an analogous mandatory sanction of dismissal of the [847]*847action, which remedy is not expressly provided by the Legislature and we decline to create it.15
We hold that the time requirements of Public Resources Code section 21167.6(a), while they do apply to jurisdictional service of the petition on the public agency, do not implicitly include mandatory dismissal if such service is not made within such limits. While the purposes of CEQA are not served by dilatory prosecution (Citizens of Goleta Valley v. Board of Supervisors, supra 52 Cal.3d 553), neither are they served by a draconian sanction for a violation of a service of process requirement which causes no real harm to the respondent to a section 21167 action.
The statute’s omission of the remedy of mandatory dismissal of the CEQA action does not, however, mean that a defendant is entirely without recourse for tardy service of the petition. As discussed above, a petitioner bringing a CEQA action cannot unduly delay service of the petition if it is to meet the other time limits of the Act. In most cases, these limits will suffice to ensure that prosecution is diligent and speedy, and that the respondents are not prejudiced by delay. However, we do not condone delays in the service ordered by Public Resources Code section 21167.6, and the courts may properly scrutinize the excuses for such delay if a respondent raises a proper challenge.
The courts of this state have a broad inherent power to control, supervise, and administer matters before them. Although this power is [848]*848partially codified in Code of Civil Procedure section 128, it is not limited by the statute and derives from the state Constitution, as based upon the historic powers of the courts. (Bauguess v. Paine (1978) 22 Cal.3d 626, 635-636 [150 Cal.Rptr. 461, 586 P.2d 942].) Courts are thus authorized to fashion new remedial procedures when it is advisable to do so, in order to deal with new issues or protect the rights of the parties. (Cottle v. Superior Court (1992) 3 Cal.App.4th 1367, 1377 [5 Cal.Rptr.2d 882].)
In the case before us, it is apparent that the Legislature intended to constrain a CEQA petitioner to accomplish prompt service of the petition. We have briefly noted above the practical fact that service within 10 business days may not always be possible; however, we believe that if a respondent challenges the service on the basis of untimeliness, the court should require petitioner to explain the delay. In some cases, good cause for the failure may genuinely exist; in others, the delay may have resulted from an excusable oversight. (See McCormick v. Board of Supervisors, supra, 198 Cal.App.3d at pp. 359-362, holding the remedial provisions of Code of Civil Procedure section 473 applicable to a mandatory dismissal resulting from a CEQA plaintiffs failure to request a hearing within 90 days of filing.) The court should then weigh any proffered excuse against any showing by respondent of prejudice to it which is attributable to the untimeliness of the service.16
In the sound exercise of its discretion, the court may then impose such a remedial sanction, if any, as may be necessary to cure the effects of delay, including the ultimate remedy of dismissal of the action, keeping always in mind the dual principles of facilitating CEQA litigation in the public interest, while protecting the rights of respondents from abusive tactics.
If the court should determine that a defendant (or real party) suffered irreparable harm from a delay in service, the remedy would be to quash [849]*849service and then dismiss the action. If the court finds that good cause or excusable neglect outweighs any prejudice to respondent, it shall order the litigation to proceed despite the tardy service. It would be an idle act to quash the service despite its technical impropriety. What is the point in quashing a late service merely to require a second late service? Therefore, if the court determines that the lawsuit should continue, on whatever terms or conditions it may impose as a remedy for the late service, quashal is improper. Here, the trial court reached the correct result by refusing to quash service and dismissing the action, although its reasoning was erroneous.
We conclude that in this case, Temecula Ranchos acted out of an excusable mistake of law, as the closeness of the question here demonstrates and County utterly failed to demonstrate any prejudice to it from not being personally served with a copy of the petition within 10 business days of the filing of the petition. It would be a fruitless act for us to grant the petition, order the trial court to grant the motion to quash and then to conduct a hearing consistent with the foregoing discussion for the purpose of making a determination whether a remedial sanction was proper for the untimely service of the petition.
The alternative writ having served its purpose, it is hereby discharged. The petition for writ of mandate/prohibition is denied.
