Conscription Age and the 27-Year Barrier
The Defence Code fixes the age frame for compulsory conscription into national military service: compulsory call-up applies to a person from 18 to 27 years of age who is on pre-conscription military register and has no ground for exemption from or deferral of call-up. These two conditions — registration and the absence of a ground — must exist together for the call-up to be lawful.
Reaching 27 carries a specific statutory consequence: a person who has turned 27 and is on military register but has not served is, on the basis of the Minister's individual administrative-legal act, granted the rank of private and enlisted in the reserve of the Defence Forces. The same happens to a person who is not on military register — upon discovery of that fact he is likewise enrolled in the reserve with a private's rank. The legal consequence of crossing the age barrier is thus resolved in this manner.
