"It reported that it unanimously agreed that found no biblical or Sister White prohibition for ordaining women to the ministry of the Seventh-day Adventist church."

Could you please quote where this was ever so stated by "the GC President's committee"? I think you are mistaken. I don't see how "the GC President's committee" would draw a different conclusion than a majority of the TOSC.

This was definitely not the case in 1990. What I recall is that the 1990 GC Session minutes record that the voted statement was that no agreement had been found on whether or not the Bible or SoP permits or prohibits such. It would be big news as far as AToday is concerned if now 25 years later agreement had been found.

"... the committee proposed to the SA General Conference to delegate to the Divisions when and how to implement women's ordination in their territory based on cultural implications locally."

This is false. There was no such proposal. A motion was voted, but nothing was recommended.
