Moreover, it is important that minor formal errors do not automatically result in the signature lists being declared invalid. Provisions should be made to allow for the correction of any formal or minor errors in the nomination and registration process. As for the 2019 parliamentary elections in the Republic of Moldova, for instance, ODIHR electoral observers criticised that the law did not allow for the re-submission of signatures to correct errors, even if the period of candidate registration was still open. Over 10% of the total of candidate applications in single-member constituencies were rejected due to various signature irregularities, there. Also in the presidential elections of 2018 in Azerbaijan, the law did not foresee the possibility of nominees to address shortcomings. On the other hand, there must be safeguards against fraudulent methods of collecting signatures. In several countries, there were allegations of forged and suspicious signatures for supporting candidates.
