The Louisiana First Circuit Court of Appeals argued that Sheriff Jerry Larpenter's investigation into the blog ExposeDAT had flawed rationale: the alleged defamation was not actually a crime as applied to a public official.

The unanimous ruling from the three-judge panel comes after police officer Wayne Anderson and his wife Jennifer Anderson were denied assistance in local and federal court.

"I love it when justice is tangible," Jerri Smitko, one of the Andersons' laywers, told The Intercept.

"With that piece of paper it says that what they did was unconstitutional — that's a great feeling because you're holding it in your hand and it's vindication for people that they intended to oppress," she added.

The raid was sparked by the sheriff's investigation into who was behind the anonymous blog that accused local officials, including him, of corruption and fraud. Through a blog and a Facebook page called "John Turner," ExposeDAT used public records to show conflicts of interest.
