Sale deed or gift deed

Hi Experts. can you provide your advice on below

1. Father's property was sold by Daughter in 1995, Without the knowledge of Father & sale deed was executed by daughter  via Notarized Power of attorney ( POA was fake).
2. After 20 year again i.e 2015 Father again gifted the property to Daughter and Daughter again gifted the property to her daughter again,

Note - Person who had sale deed from daughter did not pay tax or transferred khata till 2020, will this sale deed executed via notarized POA valid in 1995.

Now whether Sale deed sustains or gift deed !!
