High Court appointment
On 3 September 2019, Judd was appointed a judge of the High Court and assigned to the Family Division.[1][4] She took the customary damehood in the same year.[1]
In 2020, Judd was found to have made derogatory remarks about a mother to a clerk in a care proceedings case after forgetting to mute herself on a Zoom call, suggesting the mother was pretending to have a cough; Judd's refusal to recuse herself following the comments led to her ruling being overturned by the Court of Appeal and the case was remitted to the High Court's Family Division for another judge to hear the case.[5][6]
