This summary is not the rule. The rule text controls.
If a magistrate hands a defendant over to a different peace officer than the one originally named in the paperwork, the magistrate has to add a note to the commitment document first. This note tells the new officer exactly what to do: take the defendant and the paperwork to the proper sheriff.
This rule exists to keep custody of a defendant clear and accountable. Even when there's a change in who is physically handling the transfer, there needs to be a written instruction showing who is responsible for getting the defendant to the right place. This prevents confusion about who has authority over the defendant at each step of the process.
In practical terms, this means paperwork has to match reality. If the situation changes and someone other than the original officer ends up taking custody, the magistrate can't just let that happen informally. There must be a clear written direction connecting that officer's actions to the proper chain of custody, ending with the sheriff.
