dissenting.

Because I believe that this case merits the discretionary grant of oral argument, I respectfully dissent from this Court’s per curiam order affirming the order of the Commonwealth Court.

On October 5, 2001, Thomas J. Ridge resigned as Governor in order to serve, at the request of President George W. Bush, as the national Director of Homeland Security. On that day, Lieutenant Governor Mark Schweiker became Governor pursuant to Article IV, Section 13 of the Pennsylvania Constitution.1 Also on that day, Appellee, Robert C. Jubelirer, the Senator for the Thirtieth Senatorial District and the President Pro Tempore of the Senate, became Lieutenant Governor by operation of Article IV, Section 14 of the Pennsylvania Constitution.2 Since he was sworn in as Lieutenant Governor, *81Appellee has maintained his Senate seat and his position as President Pro Tempore of the Senate.

On October 17, 2001, Appellants, John A. Lawless, State Representative for the 150th Legislative District, Charles A. Pascal, a member of the Leechburg Area School District, and Joseph H. Wiedemer, a taxpayer and resident of the Thirtieth Senatorial District, filed a Petition for Review in the original jurisdiction of the Commonwealth Court, seeking a declaratory judgment that, pursuant to the Pennsylvania Constitution (1) Appellee may not continue to hold and maintain the office of a Pennsylvania State Senator and President Pro Tempore of the Senate; (2) the Senate seat for Pennsylvania’s Thirtieth Senatorial District is vacant as a matter of law; and (3) there is a need for a special election to fill the Senate seat from the Thirtieth Senatorial District. On October 22, 2001, Appellee filed Preliminary Objections to Appellants’ Petition for Review, contending that (1) Appellants lacked standing; (2) only the Senate can declare a Senate seat vacant; (3) Appellants failed to state a claim upon which relief can be granted because the Pennsylvania Constitution does not require that Appellee resign his Senate seat; and (4) separation of powers concerns do not require that Appellee resign his Senate seat. Both parties requested expedited consideration given the public importance of the issues involved, which the Commonwealth Court granted.

The Commonwealth Court sustained Appellee’s demurrer and dismissed the Petition for Review. Lawless v. Jubelirer, 789 A.2d 820 (Pa.Cmwlth. 2002). The Commonwealth Court concluded that Appellants had standing to bring the action because (1) there was a high probability that no other persons would bring the challenge; (2) the case presented a unique constitutional issue that required judicial review; and (3) Appellants Lawless and Pascal had taken oaths to defend the Pennsylvania Constitution, which conferred standing pursuant *82to Bergdoll v. Kane, 694 A.2d 1155 (Pa.Cmwlth. 1997), aff'd, 557 Pa. 72, 731 A.2d 1261 (1999). In sustaining Appellee’s demurrer, however, the Commonwealth Court held that the relevant provisions of the Pennsylvania Constitution did not require that Appellee resign his Senate seat. The Commonwealth Court also rejected Appellants’ argument that the separation of powers doctrine prohibited Appellee from holding his Senate seat simultaneously with the office of Lieutenant Governor.

On appeal to this Court, Appellants contend that the Pennsylvania Constitution mandates that Appellee vacate his Senate seat upon becoming Lieutenant Governor and that the Commonwealth Court erred in holding otherwise. In support of this argument, Appellants principally rely on Article II, Section 63 and Article IV, Section 64 of the Pennsylvania Constitution. According to Appellants, the second sentence of Article II, Section 6,5 and Article IV, Section 6 prohibit Appellee from holding his Senate seat upon becoming Lieutenant Governor.

In dismissing Appellants’ Petition for Review, the Commonwealth Court focused on the text and history of Article IV, Section 14. The Commonwealth Court noted that Appellee succeeded to the position of Lieutenant Governor by operation of this section, which provides the order of succession when the Lieutenant Governor must serve as Governor. . This sec*83tion also explains that when the governorship is vacant and there is no Lieutenant Governor to succeed to that office, the President Pro Tempore of the Senate becomes Governor. In a situation where the President Pro Tempore of the Senate becomes Lieutenant Governor, however, Article IV, Section 14 makes no express provision for the vacancy of the President Pro Tempore’s Senate seat. Relying on the principle expressio unius es exclusio alterius,6 the Commonwealth Court agreed with Appellee that if the Constitution requires that a President Pro Tempore vacate his Senate seat upon becoming Lieutenant Governor, it would provide for this expressly. As further support for this interpretation, the court quoted from the debates of the Constitutional Convention of 1873, where the original draft of the predecessor to Article IV, Section 14 provided: “[President Pro Tempore’s] Office of Senator shall become vacant when he becomes Lieutenant Governor, and shall be filled by election as any other vacancy in the Senate.” Lawless, 789 A.2d at 829 (citing VII Debates of the Constitutional Convention (1873) at 445 (Singerly, 1873)). Based on the history of the pre-enactment revisions to the predecessor of Article IV, Section 14, as well as the language of that provision, the court held that the Pennsylvania Constitution “compels the President pro tempore to resign his senatorial seat only if he becomes Governor.” Id. at 829 (emphasis in original).

With respect to Appellants’ position that Article II, Section 6 and Article IV, Section 6 disqualify Appellee from occupying his Senate seat while serving as Lieutenant Governor, the Commonwealth Court held that the position of Senator is not an “office” of the Commonwealth for the purposes of these constitutional provisions. To hold that the position of Senator is an “office” of the Commonwealth would, according to the Commonwealth Court, place Article II, Section 6 and Article IV, Section 6 in conflict with Article II, Section 9 (requiring the President Pro Tempore to perform duties of Lieutenant *84Governor in the Senate when Lieutenant Governor is absent), and Article IV, Section 14. Additionally, the Commonwealth Court noted that other provisions in the Constitution distinguish between members of the General Assembly and “officers” of the Commonwealth. See Article II, Section 7 (“[n]o person hereafter convicted of embezzlement of public moneys, bribery, perjury or other infamous crime, shall be eligible to the General Assembly, or capable of holding any office of trust or profit in this Commonwealth”); see also Article VI, Section 3 (“Senators, Representatives and all judicial, State and county officers shall, before entering on the duties of their respective offices, take and subscribe the following oath.... ”). Finally, the Commonwealth Court noted that only the Senate has the power to judge the qualifications of its members, see Article II, Section 9, and to expel one of its members, see Article II, Section 11. Lawless, 789 A.2d at 831.

In her Concurring and Dissenting Opinion, Judge Smith criticized the majority for relying on the comments of individual delegates in the Debates in interpreting Article IV, Section 14, noting that this Court disapproved of this practice in Commonwealth ex rel. Margiotti v. Lawrence, 326 Pa. 526,193 A. 46 (1937). In disagreeing with the conclusion of the majority that the role of Senator does not qualify as an “office” under the Commonwealth, Judge Smith opined that, “Article IV, § 6 unambiguously precludes a person holding state office from exercising the office of Governor or Lieutenant Governor.” Lawless, 789 A.2d at 839 (Smith, J., concurring and dissenting). Appellants agree with Judge Smith, and cite to the text of the oath mandated by Article VI, Section 3, to which a Senator must subscribe “I do solemnly swear (or affirm) that I will support, obey and defend the Constitution of the United States and the Constitution of this Commonwealth and that I will discharge the duties of my office with fidelity.” Pa. Const, art. VI, § 6.

Because this appeal involves the interpretation of the Pennsylvania' Constitution in a matter of statewide import, oral argument should be granted on an expedited schedule to allow the parties the opportunity to present argument and to allow *85this Court to address these important constitutional issues in a published opinion. Although Appellee will no longer hold the office of Lieutenant Governor after this calendar year, this Court’s decision in this matter will affect future vacancies of that office. Accordingly, I respectfully dissent.
