Indiana Code Title 1. General Provisions § 1-1-1-8

Sec. 8. (a) If any provision of this Code as now or later amended or its application to any person or circumstance is held invalid, the invalidity does not affect other provisions that can be given effect without the invalid provision or application.

(b) Except in the case of a statute containing a nonseverability provision, each part and application of every statute is severable.  If any provision or application of a statute is held invalid, the invalidity does not affect the remainder of the statute unless:

This subsection applies to every statute, regardless of whether enacted before or after the passage of this subsection.  The general assembly may preserve the legislative history of this subsection by adoption of a concurrent resolution and publication of the resolution in the legislative journals.

(c) The repeal of a statute stating that the provisions of an act are severable as provided in subsection (b) does not affect the operation of subsection (b) with respect to that act.
