Scott Schroat pleaded guilty to choking and stabbing Lila Ebright, 5, and hiding her body in 1992.
Since then, he has been serving a life sentence behind bars for the crime.
A supreme court decision would allow anyone under the age of 18 at the time of the crime to appeal for a change in sentence.
Schroat is set appear in Judge Shad Connelly's courtroom at 10a.m. for his hearing.
