Law career
Destined for the legal profession, Blackwell was called to the Bar from the Inner Temple in 1892. until his retirement in 1933. He was awarded CB in the 1911 Coronation Honours.
As chief legal advisor to the Cabinet, Blackwell was involved in the prosecution of Roger Casement, and authorised the circulation of his disputed Black Diaries, advising the Cabinet in July 1916: a Committee on Firearms Control was struck with Blackwell as its chairman. The report it issued recommended "stringent regulation" of rifles and small arms as "the number of persons who can urge any reasonable ground for possession of a revolver or pistol is extremely small [and] the danger attending the indiscriminate possession of such weapons is obvious", conclusions which led to the passage of the Firearms Act 1920.
