Why are you not asking your attorney this question? Follow the advice of your attorney; you are paying them for a reason. If you are being represented by the public defender you have to appear atyou’re your hearings.
Yes, you should ask your attorney. Ask him/her about Penal Code 977(a) which generally allows attorneys to appear for their clients. Also, if a restraining order was issued, why would another restraining order be required unless it's more restrictive.
There are certain types of cases that may require your presence at specific times. If your case has some connection to Domestic Violence, I am quite certain this will come into play. My recollection is that you must be present at the arraignment, and plea or sentencing.
