From what I understand, and Richard Hornsby would definitely know, Judge Perry was NOT in the room during pesentation and deliberation of the grand jury in the Casey Anthony indictment (in fact, no judge is present during the grand jury). He is privy now, on what went on during that grand jury, because he was going to unseal and read the transcripts this weekend.

Grand jury indicts Casey Anthony for murder of daughter Caylee Marie
October 14, 2008
Casey Anthony was indicted today on seven charges in the disappearance
of her missing daughter, Caylee Marie Anthony, including first-degree
murder.
She also was charged with:
One count aggravated child abuse
One count aggravated manslaughter of a child
Four counts of providing false info to a law enforcement officer
The decision came after an Orange County grand jury heard more than
six hours of testimony from a half-dozen witnesses, including
Anthony's father, George Anthony, and sheriff's Detective Yuri Melich,
who is heading up the investigation.
Jurors completed their work at the Orange County Courthouse at mid-
afternoon.
Chief Judge Belvin Perry, who presided over the proceeding,
received the indictment shortly before 4 p.m. today but ordered it
sealed until Anthony was arrested.
ETA: Oh i see what you're saying now. He wasn't present during the hearing. OK thanks
