The Venice Commission and ODIHR recommend including in the law a non-exhaustive list of authorities competent to assess the security situation regarding the possibility of holding an election or referendum in certain territories, involving the CEC and regional authorities in the assessment process, and regulating the manner of collaboration of the bodies involved in this process. While it is up to the Ukrainian legislator to determine the details of that collaboration, establishing a formalised inter-agency mechanism, such as a committee and/or working group, in which all relevant authorities and stakeholders - those involved in both electoral and security matters - collaborate on a single assessment and conclusion, might offer an effective solution for handling such an inter-disciplinary, politically sensitive and complex issue. The assessors should be required to provide their information/opinions in a format that systematically addresses each of the established assessment criteria. The law should also provide that any decision to cancel elections/voting in certain areas can only be taken after consultation with the CEC, including about possible alternative measures to conduct the election/voting in insecure areas. Finally, it would be advisable to establish a formal review mechanism to take place a few months after an assessment and decision on the impossibility to hold an election or referendum in certain territories to evaluate how the process worked.
