In a decision hailed by free-speech advocates, the Delaware Supreme Court on Wednesday reversed a lower court decision requiring an Internet service provider to disclose the identity of an anonymous blogger who targeted a local elected official, according to this report from the Associated Press.

In a 34-page opinion, the justices said a Superior Court judge should have required Smyrna town councilman Patrick Cahill to make a stronger case that he and his wife, Julia, had been defamed before ordering Comcast Cable Communications to disclose the identities of four anonymous posters to a blog site operated by Independent Newspapers Inc., publisher of the Delaware State News.

In a series of obscenity-laced tirades, the bloggers, among other things, pointed to Cahill's "obvious mental deterioration," and made several sexual references about him and his wife, including using the name "Gahill" to suggest that Cahill, who has publicly feuded with Smyrna Mayor Mark Schaeffer, is homosexual.

In June, the lower court judge ruled that the Cahills had established a "good faith basis" for contending that they were victims of defamation and affirmed a previous order for Comcast to disclose the bloggers' identities.

One of the bloggers, referred to in court papers only as John Doe No. 1 and his blog name, "Proud Citizen," challenged the ruling, arguing that the Cahills should have been required to establish a prima facie case of defamation before seeking disclosure of the defendants' identities.

The Supreme Court agreed, reversing and remanding the case to Superior Court with an order to dismiss the Cahills' claims.
