They are renowned for their harsh military discipline in time of war - when just about every transgression from petty theft upwards is punishable by hanging (not easy in zero-G).  The military philosophy of the Republic is summed up by the motto of the Venerian High Command :
"Carpe Diem, Carpe Jugulum"

They are fiercely jealous of their standing as a major political force. This high degree of political ambition may be why they have established a long standing tradition of what may be regarded elsewhere as political repression (such as complusory embedded ID chips) - although the Venerian government would describe this as a reasonable curtailment of dangerously subversive elements.  

Certainly the Venerian Interstellar Special Constabulary (ISC) are famous for always getting their criminal - no matter how many parsecs the perpetrator may run.
