Adnan Syed’s lawyer asked Maryland’s highest court on Wednesday to overturn a lower court’s ruling that reinstated his murder conviction from more than two decades ago — after he was freed last year in a legal case that gained international attention from the hit podcast “Serial.”

Syed’s lawyer also is asking the court to prevent her client from being incarcerated while the Supreme Court of Maryland’s review is pending

“He is grateful that the victim’s representative and Attorney General have consented to the stay,” a statement from the Maryland public defender’s office said while announcing the court filings. “Reincarcerating Adnan would be devastating for him and his family and would be an affront to justice.”

Syed’s counsel filed a petition that asks the state’s highest court to review several legal issues raised by the victim’s family, who contended they were not given enough notice to testify at a court hearing.

The legal issues include whether former Baltimore State’s Attorney Marilyn Mosby’s decision to dismiss the charges against Syed last year made the family’s court challenge moot. The issues also include whether attendance on Zoom satisfied the right of the victim’s representative to attend the hearing and whether the notice of the hearing was sufficient.

Syed’s lawyer also is asking the court to consider whether the Appellate Court of Maryland’s reversal is appropriate without showing that the result of the hearing that decided his release would have been different.

“Adnan’s innocence is not at issue, but his rights as a defendant and freedom as an exoneree are directly impacted by the Appellate Court of Maryland’s decision,” said Erica Suter, Syed’s lawyer, in a statement.

Suter said the issues raised in the case “have broader implications for our entire legal system, most notably the authority of the State to dismiss a case, the role of victims’ representatives in proceedings to redress unjust convictions, and the restrictions placed on judges’ discretion to utilize remote communication services like Zoom.”
