The "right of reply" generally means the right to defend oneself against public criticism in the same venue where it was published. In some countries, it is a legal or even constitutional right. In other countries, it is not a legal right as such, but a right which certain media outlets and publications choose to grant to people who have been severely criticised by them, as a matter of policy.

The Right of Reply service has been developed by Common Decency, Inc. to provide for the correction of incorrect facts or information that has been broadcast or published about a person (or organization), where the assertions of such incorrect facts or information have impugned that person’s honour or reputation.

A Right of Reply is primarily about the correction of incorrect facts or information. However, the platform may be used to provide for the publication of an alternative or contrary opinion, so long as the platform is not used as a stage for defamation or revenge.

If the matter is one where the published facts were correct, but not fairly presented, then a Right of Reply would be appropriate under the doctrine of fairness, objectivity and impartiality.

Where a person or organization may not be satisfied with the manner in which another speaker, journalist, broadcaster, publisher or blogger has relayed truthful information about him/her/them, then a comprehensive Right of Reply would not normally be appropriate unless the information is factually incorrect, such that their honour or reputation have been impugned. Notwithstanding, in such instances the Right of Reply platform may still be used by the affected party to balance the argument, particularly when the other publisher does not permit the subject adequate response or reply in the challenged article or broadcast.
