My ex employer tried taking me to court in November for an overpayment of wages?

I was dismissed from my job in April 2011, I had my appeal dismissed in June 2011. In January 2012 my ex employer wrote to me asking for £1400 back as I had taken so much leave before my dismissal.

I refused to pay and eventually they attempted to obtain a ccj in November 2012. I lodged a defence stating that their records were inaccurate as I had not taken anywhere near as much time off. I also pointed out that they had 20 days between dismissal and paying me to stop the payment but they didn't. Furthermore the length of time between any alleged overpayment and them contacting me was excessive and detrimental to any defence I could lodge.

Well since then I've heard nothing apart from a letter from the court saying the other party may contact me to clarify details. They haven't contacted me at all.

Does this mean that they can't take me to court anymore? Could they try again for a lesser amount now or has their time passed and it's over?
