I was happy with the first edition of this book, which I used as the basis for a Legal English course for a few years. The changes in the second edition, however, seem cosmetic at best. I have found one grammatical error so far, and the voice actors used to record the listening exercises seem to be lower quality than those used the first time around. These problems would be a lot easier to swallow if it weren't for the fact that the second edition costs twice as much as the first (at least in the country where I work).
This is still the best book on the market for teaching the English necessary for the international legal workplace, but offering a book of slightly lower quality at twice the price-that's not a recipe for long-term success.
