The editor of a learned journal is solely and independently responsible for deciding which of the articles submitted to the journal should be published, often working in conjunction with the relevant society (for society-owned or sponsored journals). The validation of the work in question and its importance to researchers and readers must always underwrite such decisions.  The editor may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding issues such as libel, copyright infringement and plagiarism. The editor may confer with other editors or reviewers (or society officers) in making these decisions.

Peer review assists the editor in making editorial decisions and through the editorial communications with the author may also assist the author in improving the paper.  Peer review is an essential component of formal scholarly communication, and lies at the heart of the scientific method, reviewers are asked generally to treat authors and their work as they would like to be treated themselves and to observe good reviewing etiquette.

Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and decline to participate in the review process.
