The author is not allowed to withdraw submitted manuscripts, because the withdrawal is a waste of valuable resources that editors and referees spent a great deal of time processing submitted manuscripts and works invested by the publisher.

1. They have clear evidence that the findings are unreliable, either as a result of misconduct (e.g. data fabrication) or honest error (e.g. miscalculation or experimental error)
2. the findings have previously been published elsewhere without proper crossreferencing, permission, or justification (i.e. cases of redundant publication)
3. it constitutes plagiarism
4. it reports unethical research

The mechanism of retraction follows the Retraction Guidelines of the Committee on Publication Ethics (COPE) which can be accessed at https://publicationethics.org/files/retraction%20guidelines.pdf.
