Parents from Abbots Langley who had their five-month-old baby taken from them for refusing to give him a name, have won the right to appeal the decision.
In May, Mrs Justice Parker said she was "troubled" by the decision to not name the child and heard how the father had assaulted one social worker and threatened to kill another, and ordered the boy be taken into care.
But last Thursday, the couple from Abbots Langley won the right to challenge the decision at the Court of Appeal, with Lord Justice Ryder ruling that the couple should be able to air their grievances before the five-month-old baby and his two-year-old brother are taken from them.
The family, who can not be identified for legal reasons, argued that they were waiting to hold a religious naming ceremony before giving the five-month-old baby a name.
Mrs Justice Parker, who sits in the Family Division of the High Court, said she was worried about the baby's mother who has a learning difficulty, but this claim was rejected by the mother after the hearing in May.
The father was said to have become frustrated by what he saw as an "invasive" approach by Hertfordshire County Council social services.
The date for the appeal hearing is yet to be confirmed.
