*566OPINION
FLAHERTY, Justice.Pursuant to 42 Pa.C.S.A. § 726 (1981), we assumed extraordinary jurisdiction of this petition for review brought by Edward M. Mezvinsky in the Commonwealth Court. Petitioner challenges the constitutionality of the limited voting provision of 42 Pa.C.S.A. § 3133 (1981) as in derogation of his constitutional right as an elector to elect the judges of the Commonwealth Court.1
42 Pa.C.S.A. § 3133 (1981) provides:
Whenever two or more judges of the Commonwealth Court are to be elected pursuant to section 3131(c) (relating to selection of judicial officers for regular terms) at the same election, each qualified elector shall vote for no more than:
(1) one-half of the number of judges to be elected, if the total number to be elected is even; or
(2) the smallest number constituting a majority of the total number of judges to be elected, if the total number to be elected is odd.
The persons having the highest number of votes, up to the total number of judges to be elected, shall be elected. This provision has been held to require limited voting in the primary election and in the selection of judges in the municipal election. Thiemann v. Allen, supra. Although there are three vacancies on Commonwealth Court to be filled in the municipal election of 1983, by operation of Section 3133 each political party would be limited to nominations of only two candidates, and each voter, in both the primary and municipal elections, would be limited to voting for only two candidates. Thus, as noted by Mr. Justice Nix, dissenting, in Thiemann, Section 3133 would preclude two-thirds of the voters from participating in selection of the candidate who will fill one vacancy. 485 Pa. at 448, 402 A.2d at 1356.
*567Pa. Const. Art. 6, § 1 provides: “All officers, whose selection is not provided for in this Constitution, shall be elected or appointed as may be directed by law.” The Commonwealth Court was created by the Constitution of 1968, Pa. Const. Art. 5, § 4, and the manner of selecting its membership is prescribed by the Constitution, Art. 5, § 13(a), as follows: “[Jjudges . . . shall be elected ... by the electors of the Commonwealth. .. . ” The meaning of this latter provision is clear: all judges, including judges of the Commonwealth Court, are to be elected by the electors who are to be served. Where electors are precluded by operation of Section 3133 from voting for candidates to fill all the vacant seats, the right of suffrage of those electors, granted in Pa. Const. Art. 5, § 13(a), is impermissibly infringed. The constitutional right to vote in a judicial election must embrace the right to participate in the selection of all judicial offices. Thus, the legislatively prescribed system requiring election of judges to the Commonwealth Court and precluding all of the electors from participating in the selection of the candidates for each vacancy on that court is contrary to the mandate of Section 13(a).
As further noted by Mr. Justice Nix in his dissent, Section 3133 could operate to frustrate the clear constitutional preference for election of judicial officers over appointment to fill vacancies. *568Id. 485 Pa. at 446 n. 4, 402 A.2d at 1356 n. 4. (Citations omitted.)
*567When we consider that there are principally two major political parties in this state offering a slate of candidates for election and that frequently they comprise the only candidates seeking election, coupled with the fact that we permit group filing in judicial elections, it is possible that the same two candidates will be nominated on both the Democratic and Republican tickets. Thus, we could be faced with a situation where the third seat could not be filled through the election process. Such a possibility would frustrate the recognized preference in our constitu-. tional scheme for judicial officers to be selected through the election process.
*568The guarantee of participation in selection of judgeships found in Art. 5, § 13(a) may not permissibly be eroded by the legislative scheme embodied in Section 3133. To the extent that Thiemann v. Allen conflicts with this proposition, it is hereby expressly overruled.
It has been argued the legislature’s attempt to prescribe limited voting in selection of judges for Commonwealth Court may be justified by that Court’s limited jurisdiction and the legislature’s perception of a need to balance the representation of each political party on that court. See Thiemann v. Allen, supra, 485 Pa. at 444, 402 A.2d at 1355; respondent’s brief at 23.
Implicit in this reasoning is the assumption that the candidate, once elected, will continue to reflect a particular political philosophy in the discharge of his judicial responsibilities. I for one do not share such a jaundice view of the judiciary in this Commonwealth. While I agree that the bench should be reflective of the various cultural, ethnic and religious groups of our society, I do not accept that this goal is realistically fostered by mandating representation by political minorities....
Id. 485 Pa. at 446 n. 4,402 A.2d at 1356 n. 4 (Mr. Justice Nix, dissenting). It is the function of the judiciary at every level to decide cases impartially and without regard to political considerations. Furthermore, although judges are chosen in a political forum, a judge’s further participation in party politics is forbidden expressly by Pa. Const. Art. 5, § 17(a), which proscribes a judge’s holding office in political parties or organizations, and implicitly by § 17(b), which proscribes activity violative of the canons of judicial conduct, as Canon 7 of the Code of Judicial Conduct admonishes jurists to abstain from political activity. Thus any legislative regulation of membership on a court according to political party affiliation must necessarily involve a useless purpose. Any suggestion that jurists decide matters before them based on party politics is an affront to the dignity and integrity of *569the Judiciary; and any encouragement to judicial officers to actively participate in political activities is condemned.
Accordingly, 42 Pa.C.S.A. § 3133 (1981) is held to be in violation of the Constitution of Pennsylvania. William R. Davis, Secretary of the Commonwealth of Pennsylvania, and Richard Anderson, Commissioner of the Bureau of Elections, Commissions and Legislations of the Commonwealth of Pennsylvania are directed to notify all County Boards of Elections and every other party entitled to notice that each political party may nominate three candidates for the office of judge of the Commonwealth Court in the primary election of 1983, and each elector in the primary election of 1983 and in the municipal election of 1983 may vote for three candidates for judge of the Commonwealth Court.
