That's a bit of a leap. The intent of the law is to protect the relationship between GP and child (which is in the child's best interest) in situations where parents dump the kids off on the GPs and spilt, then show up later wanting to "exercise their rights". While I agree the courts have gone far beyond that original intent (on GPV as well as a great many other things), to say that no court ever considered the parents' wishes is much too broad. Wishes, rights, or otherwise, when one dumps their kid off at grandma's then scoops them up the next time they sober up, there can and well should be some consideration given. In the clear cases of overstepping GPs, there should not. Unfortunately, that line is broad and blurry.
Actually...that is not quite accurate.
The original intent of the laws, back in the 1960's, was to preserve a child's connection with their grandparents in the case where their parent had died. From there it morphed, over time, into state laws being so broad that basically judges were giving ncp style visitation to any grandparent who asked for it...and in WA state, into ANYBODY asking for visitation getting ncp style visitation. In many states judges even gave ncp style visitation to grandparents of children who were not even born yet. I could tell you some real horror stories.
In the 1990's parents finally decided to seriously fight back. There were many successes at the state level in the 90's. Troxel happened in 2000, and since that time, gradually state laws were challenged to the point that a gpv is completely gone in many states, and an award of gpv is rare in all other states other than PA and NY.
Some examples of horror stories:
A woman in WA receiving visitation with her former housekeeper's child.
A man in OR receiving visitation with his former girlfriend's daughter when he and the mother had only been dating for a year and had never lived together.
A mother in KY dying in jail (due to being denied her medication) because she refused to obey a gpv order to give ncp style visitation to the grandparent of her adopted daughter (stranger adoption).
Paternal grandparents in TX being given visitation in a case where their son was caught in the act of sexually molesting his daughter, and were proven to have left the child alone with him on a regular basis while he was out on bail.
Paternal grandparents in MI doing essentially the same thing, but also who harassed the child constantly to recant and say that that it never happened...even though the child's testimony wasn't necessary as dad had been caught in the act.
Grandparents in multiple states who were given visitation of children they had flat out kidnapped from parents.
A grandmother in FL whose son had died, who was clearly unstable, who was awarded visitation and on the first weekend alone with the child killed herself and the child.
Parents in multiple states who were prohibited from relocating in order to facilitate grandparent visitation. One man lost a 100k job over a relocation denial.
The above are simplistic explanations and are only the tip of the iceberg. I was actively involved with each and every one of those families so none of it is urban legend. Its all real.
