The original business remained in the hands of his younger brothers, James and Luke Graves Hansard (1777–1851). The firm was prosecuted in 1837 by
John Joseph Stockdale for printing by order of the
House of Commons, in an official report of the inspector of prisons, statements regarded by the plaintiff as
libellous. Hansard's sheltered itself on the ground of parliamentary privilege, but it was not until after much litigation that the security of the printers of government reports was guaranteed by
statute in 1840. After 1889, the debates were published by the Hansard Publishing Union Limited. ==References==
