16/03/1957 – Edinburgh Evening News – A jury in the Court of Session, Edinburgh, have awarded damages of £2000 to James Green, a packer’s labourer, 72 Temple Denny Road, Denny, who while employed by Glenboig Union Fire Clay Co. Ltd., Glenboig, Lanarkshire, on August 12, 1953, was injured by a fall of stone in Dykehead Mine, High Bonnybridge. Green sued the company for £6000. Green was performing his duties, which included loading clay into hutches, when he saw a large stone sagging from the roof of the mine. While clearing clay from below the stone, under the directions of another employee, he was struck on the right leg when the stone fell. He blamed the other employee, for whose conduct, he claimed, the defenders were responsible. Green also contended that the defenders failed in their duty under statute to ensure that the roof of the place where he was working was made secure.
