Nowhere. There is no Biblical support for the seal of the confessional. Indeed, there's no Biblical support for the Sacrament of Confession.
What there is, however, is the First Amendment of the Constitution, which affirms the right of freedom of worship. The Roman Catholic Church has a doctrine about a priest's responsibility to keep confessional admissions secret.
So, circumventing that is going to be a knotty legal problem, and will be unlikely to succeed.
Still, there is no Biblical support for the seal of the confessional.
