Hiram Roth's exact words were as follows:
"The charges and specifications are conspiracy,; assault on Federation officers; theft of Federation property, namely the USS Enterprise
; sabotage of USS Excelsior
; willful destruction of Federation property, specifically the aforementioned USS Enterprise
; and finally, disobeying direct orders from the Starfleet Commander."
Now, this doesn't add to nine. But if you include McCoy being taken from Federation custody, the fact that multiple officers (the security guards and Mr. Adventure) were either assaulted or threatened, and it's not hard to see how they came up with nine.
