The Universal Declaration of Human Rights was created by the United Nations to provide a common understanding of what everyone's rights are. It forms the basis for a world built on FREEDOM, justice and peace.
The principles and values underlying article 19 of this declaration - the protection of free expression are: promoting the search for truth, enhancing social and political participation, and enabling self-fulfillment and self-expression.
(McLachlin in Keegstra dissent)
