The Third Circuit could ask for oral arguments once the government has filed its response. But those probably would not be heard until next year.
Contacted at his South Jersey office Tuesday, Richard Sparaco, the lawyer for defendant Serdar Tatar, said members of the defense team would not comment beyond what was said in the filing.
Tatar, 27, is serving a 33-year sentence.
His codefendants, Mohamad Shnewer, 25; and brothers Dritan Duka, 31; Shain, 29; and Eljvir, 27, are each serving life terms.
All five were found guilty of conspiring to attack U.S. military personnel in what authorities alleged was an attempt to launch a jihad in South Jersey.
Steven Downs, an attorney for Project SALAM, a Muslim legal advocacy organization, said the appeal process would be difficult for the Fort Dix defendants.
The Albany, N.Y.-based lawyer said it was his belief that appellate court decisions have been based on "government policy" rather than the law in cases involving allegations of terrorism.
In a short speech at the rally, Downs was more pointed: "This case is garbage and should be thrown out."
Standing before posters and banners, supporters contended that the Fort Dix defendants were victims of "preemptive prosecution" and entrapment.
The legal brief filed Tuesday lacked the emotionalism of the rally but covered a broad range of issues, including the constitutionality of the Foreign Intelligence Surveillance Act, prosecutorial and trial court error, and denial of the defendants' right to a fair trial.
U.S. District Judge Robert B. Kugler, who presided at the 12-week trial in federal court in Camden, found no validity in those arguments when the defense raised them after the convictions.
