The Revisor merged the language of this section in both bills. S.B. 672 was declared unconstitutional in Calzone v. Koster, et al., see 2016 annotation below. S.B. 621 was not addressed in that case; therefore, this version of this section (the 2014 language from S.B. 621, effective 8/28/2014), is the current version. (2016) Provisions of S.B. 672 from 2014 declared unconstitutional as violating the single subject rule of Article III, § 23; under the facts presented, those provisions cannot be severed and the bill is unconstitutional in its entirety. Calzone v. Koster, et al., Case No. 15AC-CC00247 (Cole County Cir. Ct., Feb. 9, 2016).
