Core non-refundable rule
The APC is non-refundable when authors withdraw an article after formal acceptance and before publication if the APC has already been paid. This applies to an author-initiated withdrawal for any reason and at any stage of copyediting, language editing, layout, proofreading, DOI or metadata preparation, or other production activity.
Editorial independence
APC payment, non-payment, refund requests, waivers, or payment disputes do not determine reviewer selection or editorial decisions. The journal may stop publication when necessary to protect participants, the journal, or the integrity of the scholarly record, regardless of whether an APC has been paid.
