However, Article 20.16 and 17 does not change the previous regulation on the control of the procedure for election campaigning, which is exercised by election commissions. The ODIHR and the Venice Commission addressed this issue in their first 2016 Joint Opinion. Paragraph 73 of the opinion noted that there were only two possible options in case of violation of the rules on campaign. The first one was an injunction by the relevant election commission to stop the activity, or a three-day warning, which was considered too rigid by the opinion. In the case this approach did not work, the next step was an application to the courts to revoke the registration of the candidate or political parties. The Venice Commission and the ODIHR reiterate their recommendations to clarify which authority is in charge of enforcing this provision and to specify by law a range of clear and proportionate sanctions for campaign-related offences.
