This contribution examines the decline of Belgian military criminal law in the two decades
following the abolition of military courts in peacetime (2004). Historically, maintaining good
order and discipline in the Belgian Armed Forces was done via three mechanisms: military
criminal law, operational discipline, and statutory discipline, all aimed at maintaining good order
and discipline within the armed forces. While the Military Criminal Code remains formally in
force, its practical relevance has sharply diminished. Statistical analysis reveals a 75% decrease
in reported martial offences between 2005 and 2024, with convictions becoming exceedingly rare.
This trend predates the abolition of military courts and could be explained by broader sociological
and institutional developments: the professionalisation and downsizing of the armed forces, the
suspension of conscription, the civilianisation of the military profession, and evolving operational
contexts that favour flexibility over rigid obedience. The contribution argues that these factors
have shifted reliance away from criminal sanctions toward disciplinary measures. However,
recent geopolitical instability, notably Russia’s invasion of Ukraine, may revive the need for
robust enforcement mechanisms, especially if conscription returns. The authors conclude that
while military criminal law still serves a complementary role, it requires modernization and
harmonization with disciplinary systems to remain effective in the 21st century.
