Selecting the category by reference to a safe country of origin or a small number of safe countries of origin will mean that the commissioner's interviewing and decision-making staff can be expert in the background information on those countries and, with the economies of scale that this brings, can address the protection issues of the applications in the selected category quickly and directly. If, on the other hand, we were to proceed on the basis that there was no prioritisation and no specialisation, it would mean that, on a random basis, officers considering applications would have to mug up on the facts of every country without taking the elementary step of concentrating those types of application in the hands of one person or a team of persons who would develop a specialised knowledge of their subject.
