Opinion by President
Judge Crumlish, Jr.,State Senators Edward P. Zemprelli, Eugene F. SeaMon, James E. Ross and Robert J. Mellow (petitioners or senators) seek, by an ¡action in the nature of *103quo warranto, to oust certain, state officials from office (respondents) and further to enjoin respondent, the Honorable Richard L. Thornburgh, Governor of the Commonwealth, from nominating anyone to succeed these officials. Respondents have filed a preliminary objection in tbe nature of a demurrer. We overrule the objection.
The Governor submitted the names of respondent officials, Robert K. Bloom, William E. Andrews, Donald L. Smith and Syed R. Ali-Zaidi, to fill certain governmental vacancies. The Pennsylvania Senate, by roll-cal] vote, confirmed their nominations, and they subsequently took office.1 During the vote in the Senate, the petitioners protested the nominations and voted not to confirm respondent officials.
The senators challenge, by an action in the nature of quo ivarranto, the officials’ right to hold office. ‘£ The writ of quo warranto is as ancient as the common law itself. .. .”2 Commonwealth ex rel. v. Wherry, 302 Pa. 134, 137, 156 A. 846, 847 (1930). In this Commonwealth, it was “the sole and exclusive remedy to try title or right to public office,” DeFranco v. Belardino, 448 Pa, 234, 236, 292 A.2d 299, 300 (1972),3 and has its genesis in the criminal law.
Historically, it was a criminal proceeding on information and resulted in the imposition of fines and sentences of imprisonment. While the *104writ soon lost its criminal character and .applied to the mere purpose of trying the civil rights involved, it retained the criminal form.
Commonwealth ex rel. Schermer v. Franek, 311 Pa. 341, 344, 166 A. 878, 879 (1933). In support of this challenge to respondents ’ right to hold office, petitioners argue that these nominations and ensuing appointments were made in violation of Article IV, §8(b) of the Pennsylvania Constitution and are thus unlawful.
The respondents have filed a preliminary objection in the nature of a demurrer, challenging these senators ’ standing to maintain this action. In arguing that the senators lack .standing, the respondents contend that the only alleged injury was to their right to vote on the nominations and that, because .the senators have exercised this right, they have suffered no injury. The senators reason that they have both a right and a duty to vote despite their .belief that these nominations were constitutionally infirm .and that they were injured by this compulsion to vote on these submissions.
In ruling on a preliminary objection in the nature of a demurrer, a court must accept all well-pleaded allegations as fact. Independent Association of Pennsylvania Liquor Control Board Employees v. Commonwealth, 35 Pa. Commonwealth Ct. 133, 384 A.2d 1367 (1978) . A demurrer will be sustained only when it appears, with certainty, .that the law permits no recovery under the allegations pleaded, Adamson v. Commonwealth, 49 Pa. Commonwealth Ct. 54, 410 A.2.d 392 (1980), and the objection must be overruled if the allegations state a cause of action under any theory of law. Sinwell v. Pennsylvania Board of Probation and Parole, 46 Pa. Commonwealth Ct. 429, 406 A.2d 597 (1979) . Thus, a court must decide any question .of law which is determinative as to the proper disposition of a demurrer. Firing v. Kephart, 466 Pa. 560, 353 A.2d 833 (1976).
*105Article IY, §8(b), upon which petitioners rely for their assertion 'that these nominations were unconstitutionally submitted, provides in pertinent part:
The Governor shall fill vacancies in offices to which he appoints by nominating to ¡the Senate a proper person to fill the vacancy within 90 days of the first day of the vacancy and not thereafter. The Senate shall act on each executive nomination within 25 legislative days of its submission. (Emphasis added.)
In Zemprelli v. Thornburgh, 47 Pa. Commonwealth Ct. 43, 407 A.2d 102 (1979) (Zemprelli I), we held that this constitutional provision mandates that the Governor submit nominations within the ninety-day period subsequent to the occurrence of a vacancy. In so holding, this Court wrote:
[A]lthough both mandatory and directory provisions are meant to be followed, a distinction arises as to the effect of non-compliance because failure to follow a directory provision does not invalidate the action but disobedience of a mandatory clause renders the action illegal and void.
Id. at 56, 407 A.2d at 108. In Zemprelli I, this Court further concluded that the requirement that the Senate act within twenty-five days of the nomination also created a mandatory duty in the Senate to vote, writing that, “ [b] ecause expiration of that 'time limit without Senate action has the positive result of placing the nominee into office, its mandatory nature is inescapable.” Id. at 59, 407 A.2d at 110. Having concluded that the duty to “advise and consent,” i.e., vote, was mandatory, we concluded that the petitioner, an individual senator, had a legal interest in ¡seeing that the Governor submitted nominations within this ninety-day period and thus had standing to maintain the action. Id. at 60, 407 A.2d at 110.
*106In Zemprelli v. Thornburgh, 55 Pa. Commonwealth Ct. 330, 423 A.2d 1072 (1980) (Zemprelli II), we further interpreted this constitutional provision to be mandatory only as to time.
Our inability to find in the constitutional provision before us a general mandate that all positions must be assiduously filled does not preclude the possibility that an executive may well be liable to compulsion to execute a program, but upon a legal basis apart from the constitutional provision at issue here____
We therefore read the provision as mandatory only with respect to time.
Id. at 346-47, 423 A.2d at 1080. Thus, this provision itself places no compulsion upon .the Governor to appoint but, if he does so, it must be done within this constitutionally-ordained period.
The senators have alleged, and we must accept this allegation as true, Independent Association of Pennsylvania Liguor Control Board Employees, that these nominations were submitted after the constitutionally-mandated ninety-day period. Zemprelli I. Thus, we must now decide whether, having fulfilled their mandatory duty to vote on these nominations, Zemprelli I, these individual senators now .have standing to challenge these submissions. Respondents assert that, once having exercised their right and performed their duty to vote, petitioners have .suffered no injury, nor do they have .a further legal interest since such interest was extinguished upon the exercise of their vote. We disagree.
Standing has been defined by the United States Supreme Court as
that “personal stake in the outcome of the controversy,” Baker v. Carr, 369 U.S. 186, 204 *107(1962), that insures that “the dispute sought to be adjudicated will be presented in an adversary contest and in a form historically viewed as capable of judicial resolution.” Flast v. Cohen, 392 U.S. 83, 101 (1968), and Sierra Club v. Morton, 405 U.S. 727, 732 (1972)....
Roe v. Wade, 410 U.S. 113, 123 (1973). Our Supreme Court, in determining the issue of ¡standing in quo warranto actions, has limited the finding of a “personal stake” to legal representatives of the public as a whole, the District Attorney or Attorney General, and to those private individuals who have a “special interest as distinguished from the interest of the public generally.” Commonwealth ex rel. Specter v. Martin, 426 Pa. 102, 108, 232 A.2d 729, 733 (1967). Here, we conclude that these senators have a grave ¡stake in assuring that nominations submitted to the Senate will pass constitutional muster.
Under Section 8 of Article IY, each state senator has a constitutional duty to vote on executive nominations for appointive office. Wilt v. Beal, 26 Pa. Commonwealth Ct. 298, 363 A.2d 876 (1976).4 This constitutional duty is implicit in the Article IV, Section 8 mandate that “ [t]he Senate shall act on each executive nomination. ...” A duty to vote on executive nominations is also imposed by the Rules of the Senate of Pennsylvania.5 Senate Rule XXII, §3, provides as follows :
Every Senator shall he present within the Senate Chamber during the sessions of the Sen*108ate, unlesas duly excused or necessarily prevented, and shall he recorded as voting on each question stated from the Chair which requires a roll call vote unless excused by the Senate. The refusal of any Senator to vote shall he deemed a contempt unless he be excused by the Senate or unless he has a direct personal ¡or pecuniary interest in connection with the pending question. (Emphasis added.)
104 Pa. Code §11.22 (c). This duty is unqualified6 and, hence, must be performed regardless of whether the nominations were, as alleged, unconstitutionally submitted. A refusal to ¡so aict, as .indicated above, invites a citation for contempt. Thus, ¡a state senator is compelled to participate in roll-call votes on executive nominations, no matter how justifiably he may contest the .constitutionality of .the submission of the nominations or the vote necessitated thereby. Thus, we disagree with respondents ’ assertion that the exercise of the vote extinguishes these senators’ legal interest in this controversy. A compulsion to vote on executive nominations conveys upon these individual senators an interest greater than,6 7 and distinguishable from, the general citizenry of this Commonwealth.8 In Zemprelli I, we held, and we now reiterate:
*109From the conclusion that the provision is mandatory, [ninety-day .submission period] it follows that petitioner ’s right to have nominations submitted within the stated period, and not thereafter, confers a legal interest and thereby gives petitioner standing herein.
Zemprelli I at 60, 407 A.2d at 110. To hold otherwise would, in this ease, allow the Governor to circumvent this provision. As we further noted in Zemprelli I, this provision was amended to avoid just such a result.
The proposing body here was a special committee to study confirmation procedures. . . . From examination of the history of recess appointments . . . and other problems, the report proceeded to note that the former language of Article IY, §8 had been accompanied by ‘ ‘indefensible delay by the Senate, circumvention of the constitutional requirement Toy the Governor and excessive political maneuvering by the Senate and the Governor,” thus subjecting both branches to criticism. (Emphasis added.)
Id. at 59, 407 A.2d at 109.
The senators have standing; thus, respondents’ objection is overruled.
Order
The preliminary objection of the respondents is hereby overruled.
At the commencement of this action, the respondents held the following offices: Bloom, Secretary of the Department of Revenue; Andrews, member of the Pennsylvania Minority Business Development Authority; Smith, member of the Hazardous Substances Transportation Board; and Ali-Zaidi, member of the Board of State College and University Directors.
For a discussion on quo warranto actions, see Comment, Quo Warranto in Pennsylvania; Old Standards and New Developments, 80 Dick. L. Rev. 218 (1976).
See League of Women Voters v. Lower Merion Township Board of Commissioners, 451 Pa. 26, 301 A.2d 797 (1973).
This is in accord with our Supreme Court’s holding, in Stroup v. Kapleau, 465 Pa. 171, 313 A.2d 237 (1973), that each individual state senator lias a constitutional right to vote on executive nominations.
The Rules of the Senate are published in the Pennsylvania Code and, hence, we are required to, and do, take judicial notice of them >in the case at hand. 45 Pa. C. S. §506.
With certain exceptions not here relevant. See Senate Rule XXII, §3.
We also note, without deciding, that the submission of executive nominations may substantially interfere with the normal course of Senate business, see Senate Rule XXX, §§5, 6, 104 Pa. Code §11.30 (c), (d), and may also provide a basis for finding that a senator's interest in the constitutionality of executive nominations is substantially different from that of the public as a whole.
Due to our holding that a senator’s duty to vote on executive nominations gives him standing to maintain this action, we find it unnecessary to address the respondents’ argument that a senator’s right to vote on executive nominaitious is not adversely affected by an unconstitutional delay in their submission.
