Papers rejected in the final review can ask the reasons by email. If you have any objection to the final review of a paper, you can consult the reasons. It needs to be clear that one of the common reasons for the rejection of the final review may be that the revision process is not in place and does not meet the requirements of the magazine. It may also be that you have published similar articles in your own magazine and don't plan to publish the same kind of articles in the near future.
