I seriously doubt it.
There have been a number of cases where people have been ordered to continue paying child support after test prove they are unrelated.
These laws are rather twisted and, in my opinion, sick.
The "view of the court" is that what is best for the child is what should be done, even if that goes against all logic.
There is also the ability to pay on the part of the one who could be asked to refund past child support. As the saying goes you can't squeeze blood from a stone. The courts award settlements but they don't collect them.
