The right to stand for election may also be subject to a condition that the candidate does not or has not previously held a specific office or performed specific functions.
This condition generally relates to offices or functions that are, by their nature, deemed incompatible with the ability to ever stand for election. Restrictions concerning prohibitions to hold two offices at once generally fall under incompatibility rather than ineligibility. International human rights law permits such restrictions, provided that they are laid down by law and are proportionate to the serious aim of protection of the democratic order.
The Estonian law prohibits persons in active service in the Defence Forces from running in parliamentary elections, local elections and European Parliament elections. This is due to the fact that Estonian law provides for a mandatory conscript service in the Defence Forces for all physically and mentally healthy male citizens.
