The Royal Mail Case or R v Kylsant & Otrs was a noted English criminal case in 1931. The director of the Royal Mail Steam Packet Company, Lord Kylsant, had falsified a trading prospectus with the aid of the company accountant to make it look as if the company was profitable and to entice potential investors. Following an independent audit instigated by HM Treasury, Kylsant and John Moreland, the company auditor, were arrested and charged with falsifying both the trading prospectus and company records and accounts. Although they were acquitted of falsifying records and accounts, Kylsant was found guilty of falsifying the trading prospectus and sentenced to twelve months in prison. The company was then liquidated, and reconstituted as The Royal Mail Lines Ltd with the backing of the British government.
As well as its immediate impact, the case instigated massive changes in the way companies were audited. The case highlighted flaws in the way company accounts were reviewed, and "probably had a greater impact on the quality of published data than all the Companies Acts passed up to that date". The case "fell like an atomic bomb and profoundly disturbed both the industrial and the accountancy worlds", and has also been linked to reduced public trust of big businesses. The case is also seen as the reason for the demise of accounting with the aid of secret reserves.
The Royal Mail Steam Packet Company was a British shipping company founded in London in 1839 by James MacQueen. It became the largest shipping group in the world when it took over the White Star Line in 1927.Lord Kylsant had been chairman of the company since 1902. He had expanded the company rapidly: aside from the White Star Line, he bought the Pacific Steam Navigation Company in 1910 for £1.5 million, the Union-Castle Line in 1912, and assumed control of the Harland and Wolff shipyards in 1924.
