If you are a mandated reporter, your job could be in jeopardy and you could be sued if you do not follow the law.
If you are a Jew, your neshoma could be in jeopardy and you could be punished if you do not follow halacha.
Therefore, I believe, that any ROV would allow you to report, and not put your job at risk.
And instead put your neshama at risk so you can keep your job?
If that is the case, what is the point of asking a ROV?
To stop yourself from breaking halacha and to save your neshama.
Would he Pasken against the law?
Rather than pasken against halacha?
