Free Expression and the Law
The right to express oneself is a fundamental human right outlined in International Law. However, most societies would agree there are types of expression that are not acceptable and which conflict with other human rights, such as selling pornography to children or promoting hate speech.
For this reason, Governments use laws to limit freedom of expression if it conflicts with other human rights, such as the protection of the rights or reputations of others, national security, public order, public health and morals.
But unfortunately, both governments and private institutions and individuals around the world can abuse such limitations, using legislation and the judicial system unjustly to control expression and to squash opposing views.
