Attorneys for accused killer Stephen Avery filed a motion Tuesday seeking to disregard Avery's telephone recordings as evidence during his time spent in prison.
Avery's lawyers argued Avery's $750,000 bail was unreasonably high for a man of his income, and that a person able to pay the bond would not be subject to such scrutiny.
Avery, who allegedly raped and killed 25-year-old photographer Teresa Halbach with his 16-year-old nephew, is awaiting trial for first degree murder. Halbach went missing in October 2005. Her charred remains were later found on Avery's property, an auto salvage yard.
Avery served 18 years in jail after being convicted of beating and raping a jogger in 1985.
After the Wisconsin Innocence Project, a campus organization dedicated to reversing the convictions of the wrongly accused, proved his innocence and won an appeal, Avery was released in 2003.
In March 2006, Avery's nephew, Brendan Dassey, offered a lurid account of Halbach's rape and murder to investigators, implicating himself and Avery.
