"After 14 days of deliberation, a New York jury said it can't agree on whether three former Dewey & LeBoeuf LLP executives committed financial fraud in the years leading up to the firm's 2012 collapse ... Judge [Robert] Stolz told the jurors to keep deliberating." - Sara Randazzo, The Wall Street Journal, October 6, 2015. Here is the article.
A mistrial would be a disappointment for the prosecution. Also, those who lost their good jobs as Dewey & LeBoeuf was tanking likely were looking forward to seeing the alleged miscreants packed off to prison.
But a mistrial is not inevitable. In the second Rhode Island public nuisance lead paint class action lawsuit, one jury deadlock was made public to the judge. He asked them to continue deliberations. Then, when I interviewed four of the six jurors, I found out that there had been a second deadlock.
How the RI jurors got through the four-months of evidence and testimony was by putting the judge's instructions to the jurors up on the wall. They followed them, line by line. Unfortunately, in this New York trial there were no written juror instructions.
