Carol Walker v. Brian Coffey, 905 F.3d 138

Background

Walker, prosecuted by Pennsylvania OAG, alleges investigators (Coffey and Zimmerer) used an invalid/blank county-court subpoena to obtain her Penn State work emails during a criminal investigation.
The subpoena was facially incomplete and unenforceable, but Penn State—through its Assistant General Counsel—searched and produced Walker’s work emails to the OAG.
After the university produced the emails, the remaining criminal charges against Walker were nolle prosequi.
Walker sued under 42 U.S.C. § 1983 alleging a Fourth Amendment unlawful-search claim; she later sought to add a Stored Communications Act (SCA) claim in a proposed second amended complaint.
The district court dismissed the § 1983 claim, finding defendants entitled to qualified immunity because a clearly established Fourth Amendment right to privacy in work-email content did not exist; it denied leave to file the SCA claim.
The Third Circuit affirmed dismissal of the § 1983 claim (qualified immunity) but vacated the denial of leave to amend as to the SCA claim and remanded for the district court to consider it in the first instance.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether defendants are entitled to qualified immunity for using an invalid subpoena to obtain Walker’s work emails	Walker: subpoena-induced production violated her Fourth Amendment right to privacy in email content	Defs: no clearly established right to privacy in work-email content; qualified immunity protects them	Held: Qualified immunity applies; right not clearly established in these circumstances
Whether Walker had an objectively reasonable expectation of privacy in the content of her work emails	Walker: emails are content communications deserving Fourth Amendment protection (relying on Warshak)	Defs: electronic-mail privacy is unsettled; third-party doctrines and workplace limitations weaken any expectation	Held: No clearly established constitutional right to privacy in work-email content for qualified-immunity inquiry
Whether an employer (Penn State) could consent to production of work emails despite an invalid subpoena	Walker: Penn State’s production was procured by law enforcement fraud/coercion, so consent was invalid	Defs: Penn State had common authority and independently consented to search and production	Held: Penn State, with common authority over the work email system, could validly produce emails; consent not deemed coerced on pleadings
Whether the district court abused discretion by denying leave to file a second amended complaint asserting an SCA claim	Walker: new SCA claim and additional facts could state a claim; should be allowed to amend	Defs: denial appropriate because amendment would not overcome qualified immunity (district court overlooked SCA)	Held: District court abused its discretion by denying leave without addressing the SCA claim; remanded for district court to consider SCA claim
