claig: "There was undue haste in despatching her back to Italy according to the judge, and the law contains a principle of no delay"
The principle of no delay relates to the wellbeing of the child: there should be no unnecessary delay in making decisions for their welfare, because of the harm which they will suffer otherwise.
The mother was sent back to Italy because she wanted to go there. That made no difference to the "no delay" principle. Whether she had stayed in this country or not, the fact is that, to stand any chance of getting custody, she had to prove that she would be no danger to the child in circumstances where the result of her illness was that her older child was traumatised and the Italian courts had found she could not look after her other children. She would have needed a very long period to stabilise and to satisfy the courts that she would not relapse - there had been occasions previously when she had improved with medication and then stopped taking it. Allowing her that time would conflict with the "no delay" principle.
The reasoning behind the no delay principle is obviously that the longer the child spends with foster parents, the more difficult it would be for her to adjust to a return to her mother, and the more damaged she would be. It is better for her that she be placed with adoptive parents quickly so that her long term future can be settled now.
