After the SDF became the British Socialist Party, in 1911, Justice continued as the weekly publication of that party, but in 1916, the group around Justice split away to form the National Socialist Party. The paper then became the organ of that party, which soon joined the Labour Party and renamed itself the Social Democratic Federation again. In 1925 Justice was renamed the Social Democrat and became a monthly. It was edited by William Sampson Cluse until its demise in 1933.
