# the communication originates in a confidence that the identity of the informant will not be disclosed;
# the confidence is essential to the relationship in which the communication arises; 
# the relationship is one which should be sedulously fostered in the public good; and

Where appropriate, "the courts will respect a promise of confidentiality given to a secret source by a journalist or an editor. However, where the public's interest in protecting sources is outweighed by other interests promises of secrecy cannot be maintained."<ref>
