We operate with very strict guidelines regarding human subjects.
The journal editorial board cannot make that decision, just as an individual investigator should not make that decision.
It is recognized that some jurisdictions have different expectations and requirements. If your manuscript uses animal or human subject derived data (including survey forms) or specimens of any kind (including teeth, saliva, tissues), evidence of IRB or local oversight committee approval that was obtained prior to beginning the study must be provided WITH the submission. In cases where your country does not ever require "permission" to use, for example, extracted teeth, there should be a written policy from the local human research ethics committee that states that no permission of any sort is required. A copy of that policy meets the journal's need to adhere to international publishing standards as described by theICMJE.
If the editorial staff determines that human or animal derived data was used to craft your manuscript, and no evidence of proper oversight is submitted, the journal will not accept the manuscript for review.
