The Election Review Board shall revoke an election and decide that there shall be a re-election in the constituency in question, if:

1. there was any deviation from the prescribed arrangements in the preparation and implementation of the election for which an authority was responsible; or 2. someone prevented voting, tampered with votes that had been cast or otherwise acted improperly in the election.

If rectification can be made by means of a recount or some other less radical measure, however, the Board shall instead direct the decision-making authority to effect the necessary rectification.

Rectification under the first or second paragraph shall only be made if there is reason to assume that what occurred impacted the outcome of the election.

A re-election to the Riksdag, a regional assembly or a municipal assembly refers only to the number of permanent seats and adjustment seats assigned to the constituency or constituencies concerned in the revoked election.
