This is adopted from the Mehran University Research Journal of Engineering and Technology.

After publication of a paper, normally no change is allowed. However, in exceptional cases, the editorial board may decide to correct, retract or remove a paper.  This decision is made when there is clear evidence of fraudulent data, plagiarism, unethical research or duplicate publication.  Sometimes, correction may be allowed when serious errors are detected due to miscalculation, experimental numerical or such other human or system generated errors. 

 The decision of correction or retraction depends on the level of allegation and may be decided on case-to-case basis. Following guidelines have been proposed by the publisher i.e. Mehran University of Engineering and Technology for such decisions. These guidelines have been derived from the  STM Guidelines and COPE Retraction Guidelines.

• If errors are introduced during the production process, an erratum may be published in both on-line and next available issue of the printed version of the journal.
• If some serious errors are made by the author which were not corrected or detected at proof reading stage, a corrigendum may be published in place of erratum on the request of the authors.
• If plagiarism, fraud, or unethical research is evident, then the original paper may be retained, and a retraction note may be added to the paper indicating the date of retraction and a brief explanation. The same note may also be published in the print version of the next issue.
• In case of duplicate publication following actions may be taken:
1. If the article does not violate the copyright of another publisher, the original paper is retained, and the retraction note is attached to it explaining the reasons. The same is published in the next available print issue.
2. If the article violates the copyright of another publisher, the editorial board may decide to remove the article from the on-line archive to avoid any legal consequences or court order etc. In such a case, the bibliographic information will be retained with a note explaining the reason of the removal of the paper. The same removal note shall also be published in the next available print issue of the journal.

The editorial board is authorized to make any other appropriate decision not listed above, if necessary.
