There is absolutely no possibility of a CCJ; the legal process was carefully written to exclude this.
If you submitted reps, and got no reply and then a CC arrived, you need to wait until the council register the debt at the Traffic Enforcement Centre, (the "court" with no courtrooms or judges). You can then submit a Witnss Statement that you submitted reps but did not get a reply. TEC then revert the process back to that stage and the council must then pass the matter to the adjudicators.
