State v. McDonnell
Annotate this Case
The Supreme Court affirmed the judgment of the appellate court reversing the decision of the circuit circuit court that examination of data contained on Defendant's hard drive was not a search in violation of the Fourth Amendment, holding that the government violated Defendant's Fourth Amendment rights in this case.
Defendant voluntarily consented to government agents seizing his laptop computer, creating a copy of its hard drive, and searching the data on it. After the copy was made but before the government examined the data Defendant withdrew his consent. Defendant moved to suppress the evidence from the forensic examination of the copy of his laptop's hard drive. The circuit court denied the motion. On appeal, Defendant asserted that he had a legitimate expectation of privacy in the mirror-image copy of his laptop hard drive. The appellate court agreed and reversed. The Supreme Court affirmed, holding (1) Defendant had a reasonable expectation of privacy in the data contained on his hard drive; (2) because the government did not examine the data before Defendant withdrew his consent Defendant did not lose his reasonable expectation of privacy in the data; and (3) the government conducted an unreasonable search by examining the data without any authority to do so.
