Additionally, the OSCE/ODIHR publication Resolving Election Disputes lists several recommendations concerning the possibility to nullify election results. Among them: (i) the decision to partially or fully invalidate election results should be assigned to the highest electoral body. This decision should be reviewable by the highest body of the judiciary or the Constitutional Court; (ii) the electoral law should specify whether the entities vested with the power to invalidate the election results can take action without being presented with a formal complaint; (iii) it should be clear from the law whether a general or restricted invalidation mechanism applies; (iv) both the preliminary and the final results should be subject to challenges.
