This is a consolidated appeal from an order of the Court of Common Pleas of Delaware County sustaining a challenge to Elizabeth Williams’ nominating petitions for the office of District Justice, District 32-1-20, in the City of Chester. We reverse.

Williams cross-filed as a candidate for both the Democratic and the Republican party nominations for the office of District *496Justice. The petitions contain 152 signatures and 120 signatures, respectively; 100 valid signatures being required for a qualifying petition.

The challenge petitions, filed by Michael Koterba and Spencer B. Seaton (Challengers), set forth general allegations 1 that “numerous signatures” are forgeries, not of registered electors, and that many persons who signed the petitions failed to insert pertinent data required by law. The challenge petitions also assert that this missing data was inserted by persons other than the registered electors who signed the nominating petitions. The challenge petitions, however, do not identify any specific pages or lines on the nomination petitions to which the general allegations are directed.

Williams filed a motion to quash the challenging petitions. After hearing, the trial court denied Williams’ motion to quash *497and granted the challenge petitions, determining that there were extensive irregularities on the nominating petitions. This resulted in an insufficient number of signatures to support the nomination.

On appeal, Williams argues that Petition of Bishop, 525 Pa. 199, 579 A.2d 860 (1990), is the controlling law and that the trial court erred in reaching the evidentiary stage at hearing because the challenging petitions lacked specificity. Williams also argues that the Cahllengers had no standing to challenge the Democratic petition and that the two-year purge conducted by the Office of Voter Registration violates Section 37 of the Act of April 29, 1937 (Act of 1937), P.L. 487, as amended, 25 P.S. § 951-37.

Initially, we note that challenges to nomination petitions must overcome the presumption of validity. Moreover, the Election Code is to be liberally construed so that candidates running for office are not deprived of that right nor are voters deprived of their right to elect the candidate of their choice. Smith v. Brown, 139 Pa.Commonwealth Ct. 304, 590 A.2d 816 (1991).

We first address Williams’ argument that the Challengers lacked standing to challenge her Democratic party nominating petition. Two cases, In re Pasquay, 105 Pa.Commonwealth Ct. 532, 525 A.2d 13, aff'd, 515 Pa. 453, 529 A.2d 1076 (1987) and In re Pinckney, 105 Pa.Commonwealth Ct. 536, 524 A.2d 1074, appeal denied, 515 Pa. 589, 527 A.2d 548 (1987), indicate that in a primary election a member of an opposing party does not have standing to challenge the nomination petition of a candidate in another party’s primary election. These holdings are based on a recognition that “any person who is registered to vote in a particular election has a substantial interest in obtaining compliance with the election laws by any candidate for whom that elector may vote in that election.” Pasquay, 105 Pa.Commonwealth Ct. at 535, 525 A.2d at 14 (quoting In re Barlip, 59 Pa.Commonwealth Ct. 178, 182, 428 A.2d 1058, 1060 (1981)).

*498The Challengers here are registered Republicans. As such, they have standing to challenge Williams’ Republican party primary nomination petition. They do not have standing to challenge her Democratic party primary nomination petition.

With regard to Williams’ next argument, she contends that any purge notices, which affected the registered voters who signed her nominating petitions, were sent out by the Office of Voter Registration in December, 1992, and thus violated Section 38 of the Act of 1937. Section 38 states in pertinent part:

Within three months after January 1 of each year, ... the Registration Commission shall cause all of the district registers to be examined, and in the case of each elector who has been registered for a period of at least two immediately preceding calendar years and who is not recorded as having voted at any election or primary during said period, the Commission shall send to such elector by mail, at his address appearing upon his registration card, a notice setting forth that the records of the Commission indicate that he has not voted during the two immediately preceding calendar years and that this registration will be cancelled or suspended at the expiration of the thirty days____

Without informing this Court that In re Johnson, 102 Pa.Commonwealth Ct. 143, 516 A.2d 1293, rev’d 509 Pa. 347, 502 A.2d 142 (1985), had been reversed, the Challengers cite to Johnson for the proposition that signatures on a candidate’s nominating petition, if purged from the voting registration files, were invalid and could not be counted as among the necessary signatures. This statement of law is correct, but in reversing Johnson the Supreme Court held that the entire purge process must be completed prior to the signing of the petition or the signature will be considered valid. However, the Johnson case does not address the validity of the purge procedure. Since the purge notices here were sent out in December, 1992, and not within three months following the first of January, as required by the Act of 1937, they are invalid.

*499Lastly, we address the specificity issue. Section 977 of the Pennsylvania Election Code (Election Code), Act of June 3, 1937, P.L. 1333, as amended, 25 P.S. § 2937, governs objections to nomination petitions. This section states:

All nomination petitions and papers received and filed within the periods limited by this Act shall be deemed to be valid, unless, within seven days after the last day for filing said nomination petition or paper, a petition is presented to the court specifically setting forth the objections thereto, and praying that the said petition or paper be set aside.

The court in Bishop directly addressed this issue. It indicated that the use of mere boilerplate allegations, rather than specific objections, does not comply with the requirements of the Election Code. The Bishop court stated “there is nothing in the Code that permits the challenger to file a general set of objections and then supplement those objections with more detailed claims after the time limit has run.” Id. at 203, 579 A.2d at 862. The Bishop court also indicated that the purpose of the statute “is to give fair notice to the person seeking a nomination that his petition contains improper signatures (or other deficiencies) and provide that person with enough information to mount a defense to the challenge.” Id. at 203-04, 579 A.2d at 862-63. In fact, the holding in Bishop could not be more clear. “[I]f the challenger claims that any signature on the petition is invalid, he must cite the page, line and reason for the invalidity in his petition to challenge. Therefore, the failure to comply with this requirement will render the challenge fatal.” Id. at 204, 579 A.2d at 863.

The trial court attempts to distinguish Bishop, indicating that the factual circumstances here differ from the Bishop case in that the Bishop objections were insufficient to set aside the nominating petition regardless of whether the specificity requirements were satisfied. This factual difference is of no moment. Bishop relied on two prior cases that held that amendments to petitions made after the seven day time limit could not cure a lack of specificity. In re Wagner, 510 Pa. 584, 511 A.2d 754 (1986); Appeal of Beynon, 370 Pa. 532, 88 A2d 789 (1952). The court must first determine whether the *500allegations raised by the challenger comply with the Election Code before examining the nominating petition for errors. Without the specificity set forth as required of the challenger, the potential candidate cannot be prepared to defend his or her nomination petition nor can the information on the nominating petition be examined for noncompliance.

The allegations made by Challengers did not advise Williams of what proof she must be prepared to present at the hearing. This failure to specify the names by page and line to which the challengers intended to object, fatally flaws their challenge petitions. Therefore, the trial court’s denial of the motion to quash and its granting of the Challengers’ petitions must be set aside.

Accordingly, we reverse the trial court’s decision.
