Mission Hen, LLC v. Lee

Plain English (For Everyone)

A company sued a former employee, Lee, for accessing company data after he left. The court ruled that since Lee had permission to access the data while employed, his actions after leaving didn't violate the law. The company's state law claims were also dismissed because the federal computer law covered the situation.

For Legal Practitioners

The Ninth Circuit affirmed dismissal of a CFAA claim, holding that an employee's post-employment use of data permissibly accessed during employment does not constitute 'exceeding authorized access.' The court also found state law claims preempted by the CFAA, lacking independent jurisdictional grounds.

For Law Students

This case illustrates that under the CFAA, 'exceeding authorized access' requires accessing information one is not permitted to access, not merely misusing information permissibly accessed. The ruling also highlights federal preemption of state law claims when a federal statute provides the exclusive remedy.

What To Do: Consult with an attorney to assess whether your access was authorized during your employment and to prepare a defense against CFAA claims.

Scenario: Your company discovers a former employee has retained and used confidential client data after leaving. You want to sue them under state law for this breach.

Is it legal for an employee to download company files to their personal computer before quitting?

Depends. If the employee has general authorization to access those files for their job duties, downloading them for personal use after leaving may not be considered 'exceeding authorized access' under the CFAA, as per the Ninth Circuit's ruling in Mission Hen. However, if the employee is specifically prohibited from downloading or retaining such files, or if their access is otherwise restricted, it could be illegal.

This interpretation is specific to the Ninth Circuit's application of the CFAA. Other jurisdictions may interpret 'exceeding authorized access' differently.

Can I sue a former employee for taking company data if they had access to it during their employment?

Depends. If the employee had general permission to access the data during their employment, and the company is alleging they misused it after leaving, a claim under the CFAA for 'exceeding authorized access' might be difficult to prove, based on the Ninth Circuit's ruling. State law claims may also be preempted by the CFAA.

This ruling is from the Ninth Circuit and may not be binding in other federal circuits. The specifics of the employee's access and company policies are crucial.

For Employees

Employees who have general access to company databases and systems for their job duties may have more latitude in how they handle that information after leaving, provided they don't access systems they are explicitly forbidden from using. However, misuse of data can still lead to other legal issues.

For Employers

Employers need to be precise in defining and restricting employee access to sensitive data. Simply having a CFAA claim might not be sufficient if the employee had general authorization to access the data during their employment. Policies regarding data retention and use after employment are critical.
