Maybe not required but certainly allowed for.Article iii of the US Constitution:
Section 1. The judicial power of the United States, shall be vested in one Supreme Court, and in such inferior courts as the Congress may from time to time ordain and establish.
And I'll wager that state constitutions are worded similarly.
What TM was stating was that if the STATE (i.e., the prosecution) requests a jury, they can have it even if the defense doesn't. The US Constitution (and many of the states) guarantees the right of the defendant to a jury trial, but it is unspecified if the state has the same right. However, there are court cases (notably the Illinois Supreme Court People v. Scornavache) that do give such right to the state.
In Ohio, if the defendant demands a jury trial, the state has to abide by it. The exception is Minor Misdemeanor charges, they are not triable by Jury.
The DA was not going to call me to testify and did not. The main witness and in their eyes the "victim". A right the defendant has is to confront the victim under cross- examination. The Sirois hearing allowed for the DA to not call me as a witness, by being declaring legally unavailable by the Judge. And in our case allowing hearsay at trial.
IMO, if a person can testify against you, similar to what you inadvertently did to your husband that night, that witness should be able to testify in court. By doing what they did in both of our trials, statements can be taken out of context, read to the jury, and never cross examined or explained.
Of course the DA wasn't going to call you to testify! DV victims are notoriously unreliable! Also, while the defendant has the right to confront their accuser, true, but that doesn't mean that the DA has to call the accuser. The defense certainly can themselves and your husband didn't assert that right). That your husbands attorney didn't assert that right is not the fault of the prosecution.
If you are appealing the conviction you can only appeal the calls of the presiding judge and whether or not the procedure of the trial was correct. You cannot call witnesses or introduce new evidence. It's not a new trial.
