Mahan sued Jay Z for co-writing credits on allegedly 45 songs. Jay Z has now reportedly filed a law suit to have Mahan’s. “After 14 years of silence, petitioner’s claims (and his attempt to use the federal courts as part of his shakedown scheme) are outrageous and wholly without merit. More significantly, for purposes of this motion, the claims are plainly barred by the three-year statutes of limitations contained in the Copyright Act, and have been for more than a decade,” Jay told Billboard.
