Arthur Hill, 2nd Marquess of Downshire
Sir William Garrow PC KC FRS (13 April 1760 – 24 September 1840) was an English barrister, politician and judge known for his indirect reform of the advocacy system, which helped usher in the adversarial court system used in most common law nations today. He introduced the phrase "presumed innocent until proven guilty", insisting that defendants' accusers and their evidence be thoroughly tested in court. Wikipedia
