[10] In this passage his Honour was concerned with the ordinary meaning of the expression "exceptional circumstances" and the approach identified is, in my view, equally applicable to the use of that expression in s.465(3). In summary, the expression "exceptional circumstances" requires consideration of all the circumstances. To be exceptional, circumstances must be out of the ordinary course, or unusual, or special, or uncommon but need not be unique, or unprecedented, or very rare. Circumstances will not be exceptional if they are regularly, or routinely, or normally encountered. Exceptional circumstances can include a single exceptional matter, a combination of exceptional factors or a combination of ordinary factors which, although individually of no particular significance, when taken together are seen as exceptional. It is not correct to construe "exceptional circumstances" as being only some unexpected occurrence, although frequently it will be. Nor is it correct to construe the plural "circumstances" as if it were only a singular occurrence, even though it can be a one off situation. The ordinary and natural meaning of "exceptional circumstances" includes a combination of factors which, when viewed together, may reasonably be seen as producing a situation which is out of the ordinary course, unusual, special or uncommon.
