Thanks, I see Tom translated it.
The relevant section would seem to be:
Of Penalties, and other Condemnations, which may be pronounced for Crimes or Delicts.
44. The effect of the placing under the superintendence (inspection) of the high police of the state, shall consist, in giving to the government, as well as to the injured party, the right of requiring, either from the individual placed in this state, when he has undergone his punishment, or from his father and mother, guardian, or trustee, if he be a minor, sufficient bail or security (caution) for his good behaviour, to the amount of the sum fixed by the sentence or judgment: any person may be admitted to furnish such security.
For want of such bail and security, the condemned remains at the disposal of the government, which has the right of ordering, either the removal of the individual from a certain place, or his continual residence in a fixed place, in one of the departments of the empire.<
However, this still only applies to those actually tried and condemned.
Presumably the law between 1804 and 1810 was based on revolutionary codes. I would be surprised if they allowed for detention or internal exile without trial given that arbitrary arrest was one of the old regime customs they most objected to.
