A state Supreme Judicial Court justice on Monday refused to alter the gag order imposed by a Bristol County judge on prosecutors who are pressing the murder case against former New England Patriots star Aaron Hernandez.

Justice Fernande R.V. Duffly ruled on the gag order issued by Bristol Superior Court Judge E. Susan Garsh. The order applies to both Bristol District Attorney C. Samuel Sutter’s office and the defense team, but only Sutter challenged the scope of the order.

Hernandez, a former tight end for the Patriots, is being held without bail after pleading not guilty to a first-degree murder charge that alleges he orchestrated the murder of Odin L. Lloyd of Dorchester in an industrial park not far from Hernandez’s home in North Attleborough.

Sitting as a single justice, essentially a gatekeeper for the SJC, Duffly wrote Monday that Sutter had neither shown that his office had been harmed by the order, nor laid out a convincing case that the gag order would hurt the way the prosecution operates in the future.
