conscription does not exist
Malawi has no conscription. In situations of public emergency, every citizen aged 18 to 60 years may be called up for national service under the National Service Act (Cap. 12:02). 
Recruitment into the armed forces is on a voluntary basis.
The minimum legal recruitment age is 18. 
2 Conscientious objection
There is no legal provision for conscientious objection.
According to the government in 1980, "Once recruited, one may not object to being deployed on conscientious grounds as this is punishable under Section 39 of the Army Act (Cap. 12:01)." 
Those who, in situations of public emergency, are called up for national service, have no right to refuse to serve on the grounds of conscientious objection. 
Apparently, disobeying military orders is punishable under Section 39 of the Army Act. 
No information available.
