No, you do not. A wrongful termination does not mean that your termination was unfair. It means that a specific law prohibits the employer from firing you for the reason he did. Nothing in the law prohibits him from terming you because he does not like you; nor does the law say that since he has not termed other people for this particular violation he can't fire you either. For all you know, he's decided that he's tired of people violating it and is making an example of you (which is entirely legal).
