Lawyers for Syed had petitioned the high court to take up the case in August, asking the nine justices to reverse a March ruling by the Maryland Court of Appeals that refused to grant Syed a new trial as he serves a life sentence in the slaying of his ex-girlfriend, Hae Min Lee, in 1999.

The petition, filed by lawyers C. Justin Brown and Catherine Stetson along with other lawyers at the Washington law firm Hogan Lovells, stated that that basis for the Supreme Court to take up the case rested on the "straightforward legal issue" of ineffective counsel provided by Syed's trial attorney, Cristina Gutierrez, who is deceased.

"At least 10 state and federal courts apply a simple approach: They compare the case that the State actually presented at trial with the case that the defendant would have presented if his attorney had been effective," the petition stated, citing in part Gutierrez's failure to call an alibi witness.

"The Maryland Court of Appeals departed from the majority approach and found no prejudice despite the failure of Syed's counsel to present an alibi witness for the exact time that the State says he committed murder. There are no vehicle problems to reaching the question at issue, which has been briefed and argued throughout three state courts. Syed should have the opportunity to present his alibi to a jury, and the jury -- not the Maryland Court of Appeals -- should decide its worth," the petition states.
