Attorneys for Adnan Syed plan to take their case to the Supreme Court of Maryland after the appeals court denied their request to overturn the reinstatement of his murder conviction.

“Appellate courts routinely assess whether an error impacted the underlying proceedings. We are dismayed that the Appellate Court of Maryland opted not to do so here. We will be seeking review in the Supreme Court of Maryland,” said Erica Suter, Syed’s attorney, in a statement.

Syed, whose case gained notoriety from the hit podcast Serial, spent more than two decades behind bars for the death of Hae Min Lee. In September, his murder conviction was thrown out, and he became a free man.

In late March, the appeals court reinstated his conviction and sentence. Attorneys for Lee’s brother, Young Lee, argued that prosecutors violated Maryland Victims’ Rights saying Lee was given short notice of the hearing in September on which he ultimately appeared on Zoom from California.

The appeals court ordered a new hearing in the case, agreeing with Kelly that Young Lee’s rights had been violated.
