How Lawyers Use Digital Evidence in Court

Web Admin - Tuesday, July 15, 2014

criminal defense digital evidenceThe advent of computer technology has reshaped the way that people communicate with each other, as well as how they treat information. This has created an interesting ripple effect in courts, which now have to deal with lawyers seeking to use digital evidence in court, which includes things like incriminating emails, computer files, and Facebook posts. 

The use of this sort of evidence comes with a variety of hurdles that an attorney must clear. The attorney must prove that the evidence is authentic and untampered with, as well as show that the records are acceptable as testimony. Prosecutors in a criminal case have a higher standard to meet, needing to show that their obtaining the evidence did not violate the defendant's privacy rights.

Hurdles to Using Digital Evidence

Lawyers face three hurdles in using digital evidence: authentication, hearsay, and privacy. Authentication refers to the need to demonstrate that the digital evidence is genuine and that no one fabricated or tampered with it. This is more difficult to show with things like emails than with physical letters because people can easily edit or alter the email's text to change the substance of the message. However, many courts still set a fairly low standard of authenticity for allowing the lawyers to present evidence to the jury; they leave the final determination of genuineness to the jury itself.

The next exception to the use of digital evidence is the rule forbidding “hearsay” testimony, which digital evidence often qualifies as. Hearsay is a statement made outside of a courtroom that the lawyer is attempting to use to prove the truth of whatever the statement is about. For instance, if a defendant is on trial for murder and one witness testifies that another witness told them they had seen the defendant commit the murder, that testimony would be hearsay since the testifying witness is just reciting an out-of-court statement.

Finally, in criminal cases, the prosecution must also show that the police obtained the evidence without violating a person's 4th Amendment rights. In many cases this means that the police must have received a warrant to perform the search, but there are exceptions to this. For instance, in the civil case of Largent v. Reed, the court determined that people do not have a “reasonable expectation of privacy” in regards to the things they post to Facebook, which would mean that a warrant would not be required to look through a person's Facebook profile.

How People Can Protect Themselves

Protecting online and digital information is a difficult prospect. Often, awareness of the public nature of things like Facebook posts, internet searches, and emails can help people stay alert to the fact that such things may be available as evidence in court. This can help modify people's behavior, and make them more careful about the sort of information that they make digitally available. Beyond that, there are some programs that can encrypt private data, but these can often be decrypted throughout the discovery process.
