A trip down the sweetshop memory lane brings to mind a whole host of childhood goodies: black jacks, flying saucers, cola cubes, sherbert fountains and, of course, refreshers. Described on one website I found as a “fizzy fruity sherbet hard candy sweet”, a refresher is also often used to describe a course or seminar that gives people an opportunity to review a particular subject. It was this latter description that came to mind when I read Akenhead J’s judgment in Wales and West Utilities v PPS Pipeline Systems.
