U.S. District Court Judge Rebecca Pallmeyer on Wednesday denied an appeal by Daley's attorneys to reconsider her July ruling.
G. Flint Taylor, an attorney for Michael Tillman, who spent 23 years in prison for a murder in which he was later exonerated, said Daley will be subpoenaed this week for questioning in early December, the Chicago Sun-Times reported Thursday.
Pallmeyer ruled in July that Daley could be listed as a defendant in the Tillman civil lawsuit against former police commander Jon Burge and former officers under Burge's command..
The lawsuit alleges Daley was part of a conspiracy to cover up the torture allegations.
Tillman, who was released from prison last year after special prosecutors said they found no reliable evidence against him. Tillman says he only confessed to the crime because he was tortured by officers under Burge's command.
