The number of covid-19 infections in Armenia has been steadily decreasing but it was still necessary to put some measures in place during election day. International organizations such as The International Foundation for Electoral Systems (IFES) have been working closely with the Central Electoral Commission (CEC) of Armenia, offering training and recommendations on how to mitigate pandemic-associated risks.
The Ministry of Health in Armenia has developed a set of hygiene protocols for the purpose of the elections. Yet there are some legal difficulties when it comes to enforcing the face mask rules in polling stations. It is not clear if polling station staff can turn voters away if the voter refused to comply with the health rules. The Armenian constitution says that any changes to core rights such as the right to vote, can only be done through laws passed by Parliament and not by regulations issued by governmental institutions like the CEC or the Ministry of Health.
