The author is not allowed to cancel the submission that is already in the review process because the cancellation or withdrawal of the submission is a wasted work carried out by the editor or reviewer.
If the author still wants to cancel the submission (at any stage), they must submit an official letter of cancellation/withdrawal signed by all authors on stamp duty. The letter contains the title of the submission, the names of author(s), affiliation(s) & address, and the reason for the canceling. Cancellation letter sent to JKP e-mail firstname.lastname@example.org and at OJS in the last discussion section.
The author who cancel/withdraw submission (at any stage) will be blacklisted for publication on JKP for 3 (three) years. The blacklist will be written the full name of the author(s) and affiliation(s) and most likely will be published.
