In British history, acts of Parliament passed 1819 by Lord Liverpool's Tory administration to curtail political radicalism in the aftermath of the Peterloo massacre and during a period of agitation for reform when habeas corpus was suspended and the powers of magistrates extended. The acts curtailed the rights of the accused by stipulating trial within a year; increased the penalties for seditious libel; imposed a newspaper stamp duty on all pamphlets and circulars containing news; specified strict limitations on public meetings; banned training with guns and other arms and empowered magistrates to search and seize arms.
