The RMA may investigate the possibility of making a Statement of Principle [glossary:(:]SoP[glossary:):] in respect of a certain disease, injury or death, or review a previous decision not to make a SoP. It can also review the contents of an existing SoP. This can be on its own initiative, or by request. The SMRC is able to review any decision by the RMA to make or change a SoP, or not to make or change a SoP, by examining the information that was available to the RMA at the time of its decision.
