The Disclosure Pilot takes effect in the Business and Property Courts of England and Wales from 1 January 2019. Michael Wheater and Charles Raffin of Hardwicke, the authors of Electronic Disclosure Law and Practice (which I reviewed in complimentary terms here) have published an article called The Disclosure Pilot: time to get ready, picking out the salient points which require attention in time for the first case management conferences after 1 January. In practical terms (and their article, like their book, is very practical), this means getting ready for it now.
My understanding is that much assiduous work has gone into making sure that judges are ready to play their (much expanded) part in operating the rules. The final headline in the article Prepare yourselves: it is later than you think, is a salutary one.
