The direction of the high court that no coercive steps be taken against the petitioner, also means that he should not be arrested. So, the police may not arrest the petitioner (against whom you lodged the FIR) till this order of the high court is in operation.
Secondly, since the police has registered FIR on your complaint, it becomes a case filed by the State. Therefore, the State is supposed to defend the case filed by the petitioner in the high court and the public prosecutor will appear on behalf of the police. So, your presence in the high court (as the original complainant) is not mandatory. At the same time, if you so wish, you can intervene in the case before the high court, and file your reply and also engage an advocate to represent you. But, this is not mandatory and is optional.
