Italy's highest court is expected to rule today whether Amanda Knox and Raffaele Sollecito should have their convictions upheld for the murder of British student Meredith Kercher.
It had been due to deliver its ruling on Wednesday, but postponed it.
British student Ms Kercher, a 21-year-old from Coulsdon, Surrey, was sexually assaulted and stabbed to death in Perugia in 2007.
Her flatmate Knox, a student from Seattle in the US, and Knox's then-boyfriend Sollecito spent four years in jail for the murder but were acquitted on appeal in 2011.
Knox returned to the US before an appeal court threw out the acquittal and reinstated her and Sollecito's guilty verdicts last year.
Italy's Supreme Court is due to decide today if it finally upholds those convictions, which would put an end to eight years of courtroom twists and turns, or orders another appeal.
