Common Examples

Lawyer Leaves Client Files Unrestricted
Ida saved investigative notes on faculty misconduct to a shared firm folder accessible to all staff. A paralegal not assigned to the matter could open the files at any time. The storage choice exposed the client information to potential unauthorized access despite encryption and a general confidentiality policy.
Fake Profile Accesses Restricted Account
Lori created a fictitious MySpace profile using a minor's name and photo. She used the profile to send messages that prompted the account holder to reveal personal details. The scheme allowed repeated entry into the protected online space without permission from the platform or the user.

Common questions
Frequently Asked
3
What distinguishes illegal access from mere unauthorized viewing in a professional setting?+
Illegal access occurs when a person intentionally enters a restricted system or file without permission. In a law firm, leaving client materials in a shared folder without access controls creates the risk of such entry by unassigned staff. The duty requires reasonable preventive measures tailored to the sensitivity of the information.
Supporting sources
Does a prior conviction for illegal access bar a later prosecution for related conduct under double jeopardy?+
A prior conviction for illegal access does not bar a later prosecution when the second offense requires proof of an additional fact and addresses a different harm. For example, a conviction for unauthorized file access does not preclude an insider trading charge that requires proof of tipping and trading activity.
Supporting sources
When does an acquittal in one state prevent prosecution for illegal access in another state?+
An acquittal bars a subsequent prosecution in another state when both cases rest on the same underlying conduct and no exception applies. The bar does not apply if the later offense was not yet completed when the first trial began.
