Today's ruling by Italy's Supreme Court ordering a new murder trial for Amanda Knox guarantees the legal drama will drag on for several more years and will be expensive.
It also raises the possibility that if Knox is found guilty and that verdict is upheld by Italy's Supreme Court, Knox could eventually face a request to extradite her and put her back in prison.
An extradition request would likely turn on whether being prosecuted again after being exonerated constitutes double jeopardy. Knox and her ex-boyfriend Raffaele Sollecito were convicted in 2009 after a lengthy and controversial trial for the murder of her British roommate Meredith Kercher in 2007.
Knox was sentenced to 26 years in prison while Sollecito got 25. That verdict was tossed out in 2011 by an appeals court that blasted the prosecution's handling of critical DNA evidence and the case in general.
