The legal battles at Death Row Records continue. After Dr. Dre recently sued his previous record label for $3 million in unpaid royalties, Death Row and former label head Suge Knight are firing back, claiming that Dre has no legal grounds for a lawsuit.

Radar Online claims that the trustee in charge of Death Row and Suge Knight's bankruptcy proceedings wants the whole lawsuit thrown out, stating that Dre already tried to collect the same $3 million years ago and was denied.

“Death Row Records, Inc. and Marion Knight, hereby moves … to dismiss the motion filed by Andre Young for allowance of his administrative claim on the grounds that the claim is barred by res judicata, on the grounds that it fails to state a claim for an administrative expense, and on the ground that the claim is barred by the applicable statute of limitations,” the legal documents claim.

In other words, the judgement has already been made and cannot be tried again. Additionally, the trustee says that no oral contract ever existed between Dre and Death Row and he "transferred away his contractual rights and copyright rights."

The famed producer-rapper, who is responsible for hits like 'Nuthin' But a 'G' Thang' and 'Let Me Ride,' was instrumental in the success of Death Row from approximately 1992 to 1996. He left the label and launched Aftermath Entertainment in 1996, amid contract disputes with Suge.
