  • Appendix a ARTICLE IX—AUTHENTICATION Sec. 9-1
    Appendix A ARTICLE IX—AUTHENTICATION Sec. 9-1. Requirement of Authentication (a) Requirement of authentication. The requirement of authentication as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the offered evidence is what its proponent claims it to be. (b) Self-authentication. Extrinsic evidence of authenticity as a condition precedent to admissibility is not required if the offered evidence is self-authenticating in accordance with applicable law. COMMENTARY (a) Requirement of authentication. Before an item of evidence may be admitted, there must be a preliminary showing of its genuineness, i.e., that the proffered item of evidence is what its proponent claims it to be. The requirement of authentication applies to all types of evidence, including writings, sound recordings, electronically stored information, real evidence such as a weapon used in the commission of a crime, demonstrative evidence such as a photograph depicting an accident scene, and the like. E.g., State v. Bruno, 236 Conn. 514, 551, 673 A.2d 1117 (1996) (real evidence); Shulman v. Shulman, 150 Conn. 651, 657, 193 A.2d 525 (1963) (documentary evidence); State v. Lorain, 141 Conn. 694, 700–701, 109 A.2d 504 (1954) (sound recordings); Hurlburt v. Bussemey, 101 Conn. 406, 414, 126 A. 273 (1924) (demonstrative evidence). The category of evidence known as electronically stored information can take various forms. It includes, by way of example only, e-mails, Internet website postings, text messages and “chat room” content, computer-stored records, [and] data, metadata and computer generated or enhanced animations and simulations. As with any other form of evidence, a party may use any appropriate method, or combination of methods, described in this Commentary, or any other proof to demonstrate that the proffer is what the proponent claims it to be, to authenticate any particular item of electronically stored information.

    Authentication of Social Media Evidence Honorable Paul W. Grimm† Lisa Yurwit Bergstrom†† Melissa M. O’Toole-Loureiro††† Abstract The authentication of social media evidence has become a prevalent issue in litigation today, creating much confusion and disarray for attorneys and judges. By exploring the current inconsistencies among courts’ de- cisions, this Article demonstrates the importance of the interplay between Federal Rules of Evidence 901, 104(a), 104(b), and 401—all essential rules for determining the admissibility and authentication of social media evidence. Most importantly, this Article concludes by offering valuable and practical suggestions for attorneys to authenticate social media evidence successfully. Introduction Ramon Stoppelenburg traveled around the world for nearly two years, visiting eighteen countries in which he “personally met some 10,000 people on the road, slept in 500 different beds, ate some 1,500 meals[,] and had some 600 showers,” without spending any money.1 Instead, his blog, Let-Me-Stay-For-A-Day.com, fueled his travels.2 He spent time each evening updating the blog, encouraging people to invite him to stay † B.A. (1973), University of California; J.D.

  • Evidence (Real & Demonstrative)
    Evidence (Real & Demonstrative) E. Tyron Brown Hawkins Parnell Thackston & Young LLP Atlanta, Georgia 30308 I. TYPES OF EVIDENCE There are four types of evidence in a legal action: A. Testimonial; B. Documentary; C. Real, and; D. Demonstrative. A. TESTIMONIAL EVIDENCE Testimonial evidence, which is the most common type of evidence,. is when a witness is called to the witness stand at trial and, under oath, speaks to a jury about what the witness knows about the facts in the case. The witness' testimony occurs through direct examination, meaning the party that calls that witness to the stand asks that person questions, and through cross-examination which is when the opposing side has the chance to cross-examine the witness possibly to bring-out problems and/or conflicts in the testimony the witness gave on direct examination. Another type of testimonial evidence is expert witness testimony. An expert witness is a witness who has special knowledge in a particular area and testifies about the expert's conclusions on a topic. ln order to testify at trial, proposed witnesses must be "competent" meaning: 1. They must be under oath or any similar substitute; 2. They must be knowledgeable about what they are going to testify. This means they must have perceived something with their senses that applies to the case in question; 3. They must have a recollection of what they perceived; and 4. They must be in a position to relate what they communicated 1 Testimonial evidence is one of the only forms of proof that does not need reinforcing evidence for it to be admissible in court.

  • Digital Identity Verification for the Legal Professional
    DIGITAL IDENTITY VERIFICATION FOR THE LEGAL PROFESSIONAL Verified.Me 1 image placeholder INTRODUCTION Trusted identity is at the foundation of the legal services profession. Lawyers adhere to stringent regulatory requirements to serve their clients and be certain that the people on the other side of a contract, negotiation, or transaction are, in fact, who they claim to be. The digital transformation of the legal services profession has upended traditional identity verification norms, forcing the industry to develop new techniques to correctly identify parties in a transaction. The Canadian legal services market, however, is in the midst of a few fundamental changes that are upending the traditional model and causing firms to rethink how they establish the trust they need to function. Increasingly, both legal services providers and their clients are engaging remotely and online. As legal service delivery evolves in this context, firms can benefit from Verified.Me’s solutions by achieving better compliance, greater customer reach, competitive advantages, streamlined secure onboarding processes, whilst protecting their customers and their assets. When clients interact with their lawyers via digital connections rather than across conference room tables, verifying identities through traditional channels becomes much more difficult. In addition, the traditional operating model for legal services is in flux. The entrenched firm model is being upended by the rise of alternative legal service providers (ALSPs) and a growing number of legal professionals working remotely. These developments are driving both existing law firms and relative newcomers to find ways to maintain high standards for confidentiality, compliance, and security in an evolving, connected market. Successfully serving clients in this new landscape requires innovative identity solutions that allow providers to address a wide array of legal functions with high assurance in client and third-party identities.

  • California State Rules of Evidence
    Introducing Digital Evidence in California State Courtsi Introducing Documentary and Electronic Evidence In order to introduce documentary and electronic evidence obtained in compliance with California Electronic Communication Privacy Act (Penal Code §§ 1546.1 and 1546. 2) in court, it must have four components: 1) it must be relevant. 2) it must be authenticated. 3) its contents must not be inadmissible hearsay; and 4) it must withstand a "best evidence" objection. If the digital evidence contains “metadata” (data about the data such as when the document was created or last accessed, or when and where a photo was taken) proponents will to need to address the metadata separately, and prepare an additional foundation for it. I. Relevance Only relevant evidence is admissible. (Evid. Code, § 350.) To be "relevant," evidence must have a tendency to prove or disprove any disputed fact, including credibility. (Evid. Code, § 210.) All relevant evidence is admissible, except as provided by statute. (Evid. Code, § 351.) For digital evidence to be relevant, the defendant typically must be tied to the evidence, usually as the sender or receiver. With a text message, for example, the proponent must tie the defendant to either the phone number that sent, or the phone number that received, the text. If the defendant did not send or receive/read the text, the text-as-evidence might lack relevance. In addition; evidence that the defendant is tied to the number can be circumstantial. And evidence that the defendant received and read a text also can be circumstantial. Theories of admissibility include: Direct evidence of a crime Credibility of witnesses Circumstantial evidence of a Impeachment crime Negates or forecloses a defense Identity of perpetrator Basis of expert opinion Intent of perpetrator Lack of mistake Motive II.
