At the trial, mr. jones's private attorney fails to show up. because the judge has a busy schedule, he moves forward without the attorney present. what is wrong with what the judge has done?

Criminal defendants have rights according to the Sixth Amendment which include the right to public trial or speedy and fair trial, right to attorney if someone wants to have one (The right violated by the judge in the above case), a fair and impartial jury and to known the charges against anyone with the identity of the person accusing.
