Today we filed our second amicus brief in the Ackerman case. Our first brief was filed in the U.S. District Court for the District of Kansas, and today’s brief was filed in the Tenth Circuit. This case involves the power of the government to conduct searches and seizures of email and attachments to email. The District Court decision upholding the search was entirely based on the “reasonable expectation of privacy” atextual judicial construct. When this case was before the Tenth Circuit previously, that Court raised the property basis of the Fourth Amendment set out in United States v. Jones in 2012, but this issue was not addressed by the District Court.
In the third section of our brief, we explain the history of the property foundation of the Fourth Amendment from before its ratification, through its abandonment, and now through its return to primacy in Fourth Amendment jurisprudence. (Now-Justice Gorsuch authored the earlier Tenth Circuit opinion focusing on the property principle.)
