The retraction is a public statement made about an earlier statement that is going to be removed from the journal. The retraction may be initiated by the editors of the journal, or by the author(s) of the paper. However, since the editors are responsible for the journal’s content, they always make the final decision to retract the material. The journal editors may retract publications even if all or some of the authors refuse to retract the publication.
Only published items can be retracted. Publications should be retracted as soon as possible when the journal editors are convinced that the publication is seriously flawed and misleading (or is redundant or plagiarized).
Authors sometimes request that articles are retracted when authorship is disputed after publication. If there is no reason to doubt the validity of the findings or the reliability of the data it is not appropriate to retract a publication solely for an authorship dispute. In such cases, the journal editor should inform those who are involved in the dispute that s/he cannot adjudicate in such cases, but they may be willing to publish a correction to the author/contributor list if the authors/contributors (or their institutions) provide appropriate proof that such a change is justified.
Retraction has no separate fee. A retracted article is a published article and consequently "article acceptance fee" will be applied to retracted articles. To know more please refer to the "Pricing" page of each journal.
