An initial page limit of 35 pages will apply to banks' submissions in respect of "general issues" before the financial services royal commission.If a party seeks to submit that it cannot deal with the issues fully with that page limit, "then that party may and should apply for an extension of the permitted length of submission, but I do ask that the basis for that application be explained and supported in detail," commissioner Kenneth Hayne said on Friday. "Putting it bluntly, it won't be enough just to say, 'I want more'," Hayne said. "I will need to be persuaded about why you need more. "for the avoidance of doubt, I should also remind parties that there are some statements that have been tendered in evidence in the course of this round of hearings that have been tendered without challenge. "Don't forget about them simply because they have not been the subject of oral examination in the course of hearings."
