In court, a High Court judge is referred to as My Lord or Your Lordship if male, or as My Lady or Your Ladyship if female. High Court judges use the title in office of Mr Justice for men or, normally, Mrs Justice for women, even if unmarried. When Alison Russell was appointed in 2014, she took the title "Ms Justice Russell ''. The style of The Honourable (or The Hon) is also used during office. For example, Sir Joseph Bloggs would be referred to as The Hon Mr Justice Bloggs Kt. and Dame Jane Bloggs DBE as The Hon Mrs Justice Bloggs DBE. When there is already or has until recently been a judge with the same (or a confusingly similar) surname as a new appointee, the new judge will often use a first name as part of his or her official title. Many judges have done this, such as Mr Justice Christopher Clarke (Sir Christopher Simon Courtenay Stephenson Clarke) and Mr Justice Roderick Evans (Sir David Roderick Evans).
