When the court has ordered severance of an indictment, the district attorney shall file separate indictments.

In the case of a grand jury indictment, no further action by the grand jury is required. Severed indictments shall be considered as filed on the date of the filing of the original indictment. Proceedings under the original indictment are not affected by the severance except insofar as they may be inconsistent with some other provision of this Code. The effects of a severance, as stated in this article, apply to severances under Articles 532(3) and 704.
