"My husband and I opened a special bottle of wine we had been keeping to either celebrate or commiserate with the court's decision," Lynne said.
"I'm just the happiest woman in Wanganui today," she told the Chronicle.
"It's such a weight off our minds, The relief is huge because our girl has a chance now.
"It's an amazing outcome for the girls and the staff and for the board who had worked so hard for the girls at the school."
She said while the Minister could appeal the decision, school supporters were hoping that would not be an outcome.
"You can't put vulnerable girls with boys. It's that simple," Lynne said.
She said the court battle had come at a cost, and she was hoping Government would front up with compensation.
She said while it did not secure Salisbury School forever, it meant it would stay open at least for another year.
"Our girl will be back there at the start of the new school year which means she will complete her two years there and another year will make a huge difference for her," Lynne said.
She said her daughter cannot go into mainstream schools without the same intensive support she received at Salisbury.
She said in the one year her daughter had been enrolled, her reading ability had lifted from that of a six-year-old to that of a 10-year-old.
She said another major concern for her and her husband was the prospect of getting involved in the intensive wraparound service (IWS) being promoted by the ministry as an alternative.
"The wraparound is a half-arsed attempt to give these girls an education. It may work for some but we know it won't work for our daughter.
"Hopefully, when she comes home at the end of next year she'll have enough social skills to take care of herself more than she can now."
