A hearing will decide whether Peter Ellis' case will be heard in the Supreme Court.
The 61-year-old died earlier this month, before his case could be heard.
He'd been fighting for decades to have his name cleared - after being convicted of child sex offences in the 90s.
The Supreme Court will hold a hearing in November, to discuss whether it can hear the appeal - given Ellis is now dead.
His lawyer argues it can - as it was lodged while he was still alive.
