It is very difficult to answer this question without knowing what was "uttered" in this case. In the context of criminal law, “utter” denotes the putting into circulation of forged documents, money, etc. or counterfeited goods. It appears that the person in question was convicted not only of forgery, but also of putting the forged items into circulation (using a false document, spending false money, distributing counterfeit goods, etc).
