For those who asked what they are missing, it is simply a clarification of long standing Louisiana law and a cleaning up of civil code and it’s ancillary (r.s. Chapter 9) language.
The concept is that joint parental authority is derived from the marriage. That joint authority, including the right to represent a child as embodied in civil code chapter 5 is terminated upon death, incapacity of a parent or divorce (when the judgement of divorce transfers it to one or both parents individually, as determined by the best interest of the child).
There is no change in the law, no sinister motive or hidden agenda.
