"So the court might ignore the complainant's filing of case against me? Is that possible?"
Please let me clarify first:
If the complainant will also sue you, he will go to the Prosecutor's Office (not the court yet).
When he files the complaint at the Pros Office, the investigating prosecutor will either:
1. dismiss the case immediately if he does not believe the complainant or
2. order you to submit your counter affidavit before deciding whether he will dismiss the case or file the case in court. Your counter-affidavit (prepared by your lawyer) explaining that the complainant is just getting back at you (resbak) because of your testimony might convince the prosecutor to dismiss the case.
3. If ever the prosecutor rules that your claim of "resbak" is just a matter of defense, he will still file the case in court.
4. After trial and the case is submitted for decision, this is the time that the court will decide if your claim (that the complainant is just retaliating against you) is true.
