Lawyers for a California minister and his wife say their clients should have gotten a chance to show a jury that they had evidence of rape against singer Celine Dion's husband.
Instead, Ae Ho Kwon and Yun Kyeong Kwon Sung were convicted of
extortion without Rene Angelil taking the witness stand against them.
That's the argument that attorneys Robert Langford and Lisa Rasmussen made today before the Nevada Supreme Court.
In questioning the lawyers, justices compared the case with the case of Donald Phillips, who claimed to be casino mogul Steve Wynn's half-brother.
The state high court reversed Phillips' extortion convictions in 2005 -- although he's still in prison for stalking.
Kwon and Sung are in prison after threatening to go public with allegations that Angelil raped Sung at a Las Vegas Strip hotel in 2000.
Their lawyers say truth is their defense -- but they never got a chance to tell it.
The trial judge ruled Angelil didn't have to testify -- and refused to compel a DNA sample from him.
