Article 12. The freedom of the individual is guaranteed.
No one can be prosecuted except in the cases provided for by the law, and in the
form prescribed by the law.
Except in the case of a flagrant offence, no one can be arrested except on the
strength of a reasoned judge’s order, which must be served at the latest within forty-eight
hours from the deprivation of liberty and which may only result in provisional detention.
