Answer:
No, because the U.S. Safe Web Act provides immunity to the ISP from liability for such action.
Explanation:
In the Safe Web Act actually states that ISP and other information sharers must follow some rules and thus enjoy some advantages when helping the government fight spam, spyware, and Internet fraud and deception.
One of these rules is called Reciprocal Information Sharing. In this article of the Safe Web Act, an ISP is permitted to share confidential information without a customers approval if required by the government in order to halt fraud, deception, spam, spyware and other consumer protection law violations targeting him or her.
If the ISP does this, is automatically protected by the Article 8, which covers the ISP with immunity to lawsuit, or liability from sharing private information with the government in a voluntary manner needed to prevent or halt wrongdoings to the customer or federal agencies.
