If no declaration is filed, a vacancy shall exist upon the expiration of the term of office of such judge, to be filled by election under subsection (c). If a judge files a declaration, his name shall be submitted to the electors without party designation, as a separate judicial question or in a separate column or line on voting machines, at the municipal election immediately preceding the expiration of the term of office of the judge, to determine only the question whether he shall be retained in office. If a majority is against retention, a vacancy shall exist upon the expiration of his term of office, to be filled by appointment under section 3132(a) (relating to vacancies in office). If a majority favors retention, the judge shall serve for a regular term of office provided for in section 3152 (relating to tenure of judicial officers), unless sooner removed or retired. At the expiration of such regular term such judge shall be eligible for retention as provided in section 3153 (relating to retention elections after regular term), subject only to the retirement provisions of this part. Section 3133 (relating to Commonwealth Court judges) shall not be applicable to an election conducted pursuant to this subsection.
