Grant was delighted with the result after such a traumatic week.
"If I wrote a book about Portsmouth it would be a best-seller," he said.
"I see the passion of everyone at the club - the fans, the players and the staff. There is a passion to succeed. I was very happy to see the decision from the High Court. There are many people around and it's not their fault.
"I had two choices. To give up or to show to the players that we will make our spirit even higher. I said that to the players and to my children when there are difficult times you need to show your character."
