Recount of the vote only with respect to those polling stations where it is legally justified 525. The vast majority of EDR systems provide legal justification for a partial recount, although the burden of proof required for this may be high. These EDR systems assume that the accuracy of the election results has been guaranteed by the multiple security measures established for appointing the polling station officials, identifying the voters, carrying out the voting itself, and counting and tallying the votes received at the polling stations. A return of the votes received is drawn up and signed by the officers at the polling station. Political parties may be represented at every polling station; they or their representatives have the right to file a protest in response to any irregularity or anomaly they may have noted on election day, and to receive a copy of the vote count protocols and tally as proof of the result obtained at the polling station. 526. Each political party, through its representative, is then able to compare their copy of the results from the polling station with the vote tally carried out by one of the organs of the EMB in the days immediately after election day. In several EDR systems, the law provides that a recount of the votes received at a polling station can be requested if during the tally by the EMB: • the declaration of the counting and of tallying the vote received at a particular polling station shows signs that it has been altered; • there are clear errors in the data it sets out; • such a declaration does not exist; or • the data it shows are not in agreement with the data in the copy that the political parties’ representatives have. These circumstances would indicate a partial recount of the vote received at a certain number of polling stations. 527. Political parties, and in several EDR systems candidates, have the right to challenge the results of the EMB’s vote tally before the EDRB, either to uphold their right with respect to alleged irregularities committed on election day that were not corrected in the EMB’s vote tally, or because the EMB has committed new irregularities. In the event of an improper omission by the EMB, the EDRB is able to conduct the recount of the vote received at the polling stations concerned. 173 7.
