Prohibiting persons who engaged in wrongful conduct from recovering damages in certain civil actions, prohibiting certain public nuisance claims, providing that only the attorney general may file claims regarding public nuisances that are not wholly contained in one political subdivision unless the attorney general delegates authorization to file such claims and requiring special injury for certain public nuisance actions.

Removed the requirement that the Attorney General must get written approval from the Governor before filing a public nuisance claim involving multiple political subdivisions.

Added a new provision allowing private individuals to file public nuisance claims, but only if they can prove they suffered a 'special injury' distinct from the general public.

Changed the standard for private plaintiffs from a 'preponderance of the evidence' to a higher 'clear and convincing evidence' standard to prove the defendant caused their specific injury.

Removed the restriction that prevented courts from awarding monetary damages (including economic or punitive damages) in public nuisance cases filed by government entities.

Added specific rules for private plaintiffs, including a ban on class actions and a limit on damages to only those costs not already reimbursed by the government.

Added the ability for the Attorney General to delegate the right to file cross-border nuisance lawsuits to local political subdivisions.

Modified the list of non-nuisance actions to include an exception: actions authorized by law are now considered a nuisance if they result from negligent conduct.
