Unethical Document Signing Concerns

I work as a courthouse interpreter. One day, I was at one courthouse. Once I finished, my agency asked me to go to the second courthouse. They didn't have a case to assign me, but they asked me to go anyway and check if the court still needed an interpreter. I went to the second courthouse, already exhausted. I arrived and I found out the clerk. She ordered me to sign a form saying that I had assisted a quick trial. She said the quick trial had ended. It was drink driving case. The suspect had brought his own lawyer who translated for him. The suspect conceded to the offence, and accepted a plea bargain for a reduced penalty and accepted a fine and the removal of his driving licence. Paula said she understood the suspect, but the prosecutor insisted on having an interpreter sign it. She intimidated me into signing the form for a hearing that I had never attended.
