Legal Question in Criminal Law in North Carolina

Of course not. All that is required is that they in fact have a warrant. You indicated you did not know about the failure to appear as if this somehow lessens your responsibility for it. You hired an attorney, so you clearly knew you had legal matters pending and taking care of your legal matters properly is your responsibility including making sure you appear. Also the nature of your question seems to indicate you are asking to see if there is someway to have your responsibility for your charge lessened. If you spend half as much time being responsible and avoiding getting into trouble in the first place as you do trying to avoid responsibility for the consequences of your bad choices - you'd likely have a much better life.
