Thank you for the information and your question. I can't give her, or you, legal advice since I do not have all of the facts, including the evidence in the possession of the State and because we cannot form an attorney-client relationship. But I can tell you what the consequence would be if she does not appear in court after being subpoenaed. That would be that she would be charged with contempt of court and likely arrested and forced to appear at some point. In addition, as you might guess, not only might her husband's charges be dismissed, although that really depends on what other evidence there is against him, but he is likely to do this again. I have prosecuted domestic violence
cases for years and also assisted battered women and I can tell you that this situation will not get better if she does not follow through with this and make sure he is held accountable for his actions.
I can also tell you that if her husband's attorney really told her not to show up to court, that he or she has broken the law (witness tampering and witness intimidation
) as well as violated their State Bar ethics rules. So, your friend should seriously consider going to the prosecutor who has her case and telling them what is going on. Not only may the attorney for her husband be removed or sanctioned but, as I mentioned, the attorney and her husband could be charged with those additional charges. If she needs protection, then she should, if there isn't already one, ask for a protective order and consider going to a women's shelter.
I can't emphasis enough that if she gives in to this intimidation, she will be the one to pay, not her husband.
Please let me know if you need any clarification. I would be glad to assist you further if I can.
