Good question. The term "unresolved" mentioned at a person's arraignmant can mean many things depending upon the context that the answer to the question given by the district attorney's office.From the brief question that you have written, it could mean that there has been no real settlement discussions between the district attorney's office and the accused/defendant.If the defendant in this criminal matter does not have a criminal defense attorney, he or she should retain one sooner rather than later. My experience is that people charged with a crime fair much better with a criminal defense attorney in the end representing him or her.
