(2) Nothing contained in or done under the authority of any law shall be held to be inconsistent with or in contravention of this section to the extent that the law in question makes provision— (a) that is reasonably required in the interests of defence, public safety, public order, public morality or public health; or (b) that is reasonably required for the purpose of protecting the reputations, rights and freedoms of other persons or the private lives of persons concerned in legal proceedings, preventing the disclosure of information received in confidence, maintaining the authority and independence of the courts, regulating educational institutions in the interests of persons receiving instruction therein, or regulating the technical administration or the technical operation of telephony, telegraphy, posts, wireless, broadcasting or television; or (c) that imposes restrictions upon public officers, employees of local government bodies, or teachers, and except so far as that provision or, as the case may be, the thing done under the authority thereof is shown not to be reasonably justifiable in a democratic society."
