This wasn't brought to the state's attention until the last minute so there was no time for a written response. The references to the state making written responses, including asking the court to direct same, were specious at best, imo. The defense often files last minute pleadings, amended pleadings, additional pleadings, etc. precluding written responses from the state. So far, iirc, the state has provided written responses for the most part when time allowed and subject matter indicated. Trial by ambush is generally disfavored in Florida courts and I doubt the state has in any way tried to do so. If that was their intent and time allowed, I think TP would have been present at the hearing along with other evidence to dispute the validity of the proffered document.
JB's real issue may be, imo, that had he been made aware that the document would be questioned, he could have taken some preemptive measures or even canceled the hearing on that issue. I don't think he would have brought the original to court with him because I don't think it exists. If it did, I think it would have been in one of the file folders regarding this issue sitting on the defense table.
JB also whined about being called on the carpet about this, my impression being in hopes the court would chastise the state for making such "scurrilous" accusations against him and thereby possibly hoping to avoid actually having to produce what he likely doesn't have. If TP's memory is correct, then rather than admit it in open court, I'd be more inclined to believe JB would walk to the end of the hallway, as did his client. He would have nothing to gain by such an admission, even an unspoken admission. JB, like his client, in my view seems to be more likely to instead be furiously trying to figure out how to avoid detection; come up with another lie/fraudulent document; and/or a way to blame someone else for the fabrication.
Keep in mind, these are very serious allegations and I highly doubt TP would make them lightly. TP is much too smart, imo, to not realize possible repercussions from false accusations, especially considering his profession.
