The limits of the legal scope of unilateral approval

Unilateral approval is simple in theory. However, its practical application raises one or two problems not only with regard to international transport, where its interpretation differs somewhat between countries, but also with regard to domestic transport, where certain countries would like to see it applied. An attempt is made here to identify the aspects which give rise to misunderstandings in this area and to propose a way of overcoming those misunderstandings, which create difficulties for the transport of radioactive materials.
