All submitted manuscripts are reviewed through a 'double-blind' peer review process that means the identities of the authors are kept confidential from the reviewers, and vice versa.

To make this possible, anonymized versions of the manuscript are sent to referees. Submitted papers are first considered by the editor after submission. Papers that do not fall within the scope of the journal are 'desk rejected. In addition, papers that fail to meet a minimum threshold for quality and originality are also rejected without being sent out to the reviewers.

Papers passing through this initial editorial scrutiny are then typically sent out to a minimum of two referees (one national and one international). ". If one or more of these turn down the invitation to provide a review, other referees will subsequently be appointed. Normally, at least two authoritative reviews are needed before the respective editor can make a decision as to whether to accept, reject, or ask for a 'revise and resubmit' of the submitted paper.
