Accurate News and Information Act

The Accurate News and Information Act (complete title: An Act to Ensure the Publication of Accurate News and Information) was a statute passed by the Legislative Assembly of Alberta, Canada, in 1937, at the instigation of William Aberhart's Social Credit government. It would have required newspapers to print "clarifications" of stories that a committee of Social Credit legislators deemed inaccurate, and to reveal their sources on demand.
