I had to do mine twice.
First year I was absolutely terrified and managed to tell my truth in the courtroom. I couldn't look at anyone but a blank space on the wall in front of me.
Everyone on my side gave their evidence as well and he was able to sit and listen to everyone testify.
I was able to clarify some of the things he said occured that day and it showed that he was lying.
One of the things he had said is he couldn't do what he had done because he had a broken arm.
This was proven untrue and hospital records were produced to show that he had broken his arm a long time after the assault.
Just before it was his turn to testify, his solicitor decided he could no longer represent him because he was lying.
I don't know if that was to buy him some time or not though because it meant there would be grounds for an appeal if he was unrepresented. The judge ordered a retrial because of this.
I'm sure his solicitor knew this and pulled that tactic to allow him to change his story and hire someone else.
I didn't want to do it again initially. The police begged me to and said I could have special measures in a room away from the courtroom.
It took another year to go to court again.
This time, everything that he was caught out lying about was left out of his testimony. He changed his story based on what he'd heard the previous year.
I still told the truth regardless, but the barrister asking me questions asked me what I was wearing that day (a black suit, it was a funeral wake) and made up stories that didn't happen but presented them as fact.
I stumbled over this because I knew what he was saying was completely untrue, but he said it in a way that made it sound like facts. I just kept saying that it wasn't true and was verging on a panic attack.
They wouldn't allow the police to testify on my behalf either the second time round. I still don't know why.
I lost my case. My mum had to tell me the verdict because I couldn't be there due to my anxiety. She said it was a hung jury but I'll never know.
I'm still waiting for the court/CPS to ring me and tell me the verdict because they didn't bother to inform me either.
This was 6-7 years ago.
