Online Research by a Juror Leads to Mistrial

There was a “manifest necessity” to declare a mistrial after a court learned of a juror that researched issues related to the trial on their own.

Slavick v. Sequeira, 2016 BL 314700, D. Haw., No. 15-00424 DKW-KJM, 9/23/16.

A U.S. District Court in Hawaii found that a mistrial due to a juror’s independent research of an issue related to the trial created a “manifest necessity” that would not implicate an issue of double jeopardy. The issue arose because the defendant argued that a new trial after the initial mistrial would create an issue of double jeopardy. The court rejected this argument, finding that the trial court did not “falsify” reasons for the mistrial and that there was a “manifest necessity” for a second trial. The court further expressed concern over the problems of technology during a trial, stating, “after the jury had been exposed to the extraneous information, ‘the interests of public justice would not be served by a continuation of the [trial] proceedings[,],' and that manifest necessity existed to declare a mistrial.” The opinion continued by saying, “Because the mistrial was supported by a valid determination of manifest necessity, the second trial that resulted in [the defendant’s] conviction did not violate the Double Jeopardy clause.”
