Lil Durk is attempting to have his federal murder-for-hire charges thrown out.
The Chicago drill star says his indictment is missing key details about the bounty he supposedly placed on rival rapper Quando Rondo in 2022.
He has argued that he can't prepare a defence when prosecutors have laid out only a vague theory about him ordering the hit.
"This indictment is impermissibly vague," writes Durk's legal team.
"It leaves the defence to guess as to the government's theory of guilt, and it leaves the government free to change that theory as its cooperators' stories morph over time to meet the demands of a conviction."
The rapper (real name Durk Banks) was arrested last year for allegedly ordering members of his Only the Family (OTF) crew to travel to Los Angeles and shoot Rondo.
The 2022 shooting at a Los Angeles petrol station left Rondo (Tyquian Bowman) unscathed, but Rondo's friend Lul Pab (Saviay'a Robinson) was killed in the crossfire.
According to Durk's attorneys, a fair murder-for-hire indictment should specify precisely what bounty was offered and how exactly that offer was communicated. Durk's indictment states merely that he used "coded language" to tell OTF crew members that he'd reward Rondo's killers with money or "lucrative music opportunities".
This is the second time Durk's lawyers have tried to have charges thrown out since his arrest last October.
Durk has been awaiting trial from jail, having tried and failed numerous times to get bail.
