Called to the bar in 1932, Krusin completed pupillages in the chambers of Arthur Cole and J. H. Stamp, and then in 1933 joined the chambers of Hubert Rose, a key influence on him.[2] In 1940, he was commissioned as a Pilot Officer in the Administrative and Special Duties Branch of the Royal Air Force Reserve.[4] His war service involved interpreting radar sightings of enemy aircraft and predicting their movements; his commanders had decided to recruit lawyers and stockbrokers for this work, believing that they were well-trained in quick analysis. After a year, he moved to the Air Staff and eventually rose to the rank of Wing Commander.[2]
In 1945, with the war over, he joined the British Tabulating Machine Company as its deputy secretary, but found the work less interesting than he had hoped. He contacted Noel Hutton (who had also been in Stamp's chambers) at the Office of the Parliamentary Counsel, to enquire about work, and it happened that the OPC was recruiting. He was appointed an assistant there in 1947, and promoted to senior assistant in 1949.[2] Four years later, he was made a Parliamentary Counsel, and then in 1970 he was promoted to Second Parliamentary Counsel, serving until retirement in 1973.[5]
