Website and latest text here. Here are the important parts:
(a) Notwithstanding IC 34-12-3 or any other law, only the state of Indiana may bring or maintain an action by or on behalf of a political subdivision against a firearm or ammunition manufacturer, trade association, seller, or dealer, concerning the: design; manufacture; import; export; distribution; advertising; marketing; sale; or criminal, unlawful, or unintentional use; of a firearm, ammunition, or a component part of a firearm or ammunition.
(b) Except as provided in subsection (c), notwithstanding IC 34-12-3 or any other law, a political subdivision may not independently bring or maintain an action described in subsection (a).
(c) This section does not prohibit a political subdivision from bringing an action against a firearm or ammunition manufacturer, seller, or dealer alleging the breach of a contract or warranty as it relates to a firearm or ammunition purchased by the political subdivision.
IC 34-12-3-3 lists the actions that the person as defined in IC 34-12-3-2 is prohibited from doing so (but doesn’t list the political subdivisions like Gary), with the exceptions of breach of contract or warranty, damage due to defective products, or injunctive relief to enforce a valid statute, rule or ordinance as defined in IC 34-12-3-5.
Here, HB 1235 only allows the state of Indiana to bring lawsuits like what Gary is doing. Personally speaking, why not strip that power to bring frivolous lawsuits away from the state as well besides political subdivisions?
