“Legal documents of unnecessary and too often of excessive length offer very little assistance to the court. In Tombstone Ltd v Raja[2008] EWCA Civ 1441 ,[2009] 1 WLR 1143 Mummery LJ said: "Practitioners ... are well advised to note the risk of the court's negative reaction to unnecessarily long written submissions. The skeleton argument procedure was introduced to assist the court, as well as the parties, by improving preparations for, and the efficiency of, adversarial oral hearings, which remain central to this court's public role... An unintended and unfortunate side effect of the growth in written advocacy... has been that too many practitioners, at increased cost to their clients and diminishing assistance to the court, burden their opponents and the court with written briefs." He might have penned those remarks had he been sitting in these two cases, and many more, in this Division. In Standard Bank PLC v Via Mat International[2013] EWCA Civ 490 , [2013] 2 All ER (Comm) 1222 the excessive length of court documents prompted: "It is important that both practitioners and their clients understand that skeleton arguments are not intended to serve as vehicles for extended advocacy and that in general a short, concise skeleton is both more helpful to the court and more likely to be persuasive than a longer document which seeks to develop every point which the advocate would wish to make in oral argument." No area of law is exempt from the requirement to produce careful and concise documents: Tchenquiz v Director of the Serious Fraud Office[2014] EWCA Civ 1333 ,[2015] 1 WLR 838 , paragraph 10.”
