Authors are discouraged from withdrawing submitted manuscripts after it is in the publication process (review, copyedit, layout, etc.,). During the time, Pi: Mathematics Education Journal (PMEJ) had spent valuable resources besides time spent in the process. Should under any circumstances that the author(s) still request for a withdrawal, author(s) should pay back every effort put into the manuscript processes. Paid upon official request from the author(s) in an email sent to editor using the same email address used in correspondence.

Editors shall consider retracting a publication if:

• 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)
• the findings have previously been published elsewhere without proper crossreferencing, permission or justification (i.e. cases of redundant publication)
• it constitutes plagiarism
• it reports unethical research

The mechanism follows the guidelines from the Committee on Publication Ethics (COPE) which can be accessed at https://publicationethics.org/node/19896.
