Concerns about inconsistencies between the Codes and their empowering Act have been raised by scholars and commentators since the Act’s early days. Gaps between the Act and its Codes became more discernible after the Act was amended in 2015. That amendment also improved the legislative vehicle for dealing with inconsistencies.
