I. Introduction

[1]       More than ten years ago, the Zubulake case[1] raised awareness of the importance of digital evidence in litigation. At that time, for many lawyers, the discovery process consisted of collecting paper documents, manually reviewing those paper documents, and responding to document requests by producing paper documents. Digital evidence existed, but was more limited in scope and volume than it is today. Back then it was often overlooked or not recognized as a potential source of valuable evidence to be obtained in discovery.

[2]       In the post-Zubulake era, the ways in which companies and individuals create and maintain information have changed dramatically. Many types of documents that were traditionally created on paper and stored in hard-copy now never exist on paper. Instead, they are created on computers or other digital devices and stored in e-mail archives, on backup tapes, or in the cloud. Business and personal communications that once took place via letters and faxes are now transmitted through e-mails and text messages. Microsoft Excel files replaced handwritten accounting ledgers. Medical records are routinely created and stored electronically, making the paper medical file a thing of the past. Carbon copy secretarial message books with tear-away message slips are replaced by programs that transcribe voicemail messages and deliver them to the recipient by e-mail. Designs are created and maintained in CAD files rather than drawn on paper. Many businesses advertise primarily, if not exclusively, on social media and the Internet and little, if at all, through paper mailings. Employees traded in paper calendars and address books for electronic schedulers, using programs and applications that reside on their computers and mobile phones.

[3]       The prevalence of digital information, and the corresponding decline in the use of paper for the creation and storage of information, profoundly affected litigation, including discovery and trials. The “documents” and information that are requested and produced in discovery are overwhelmingly electronic documents and data. Electronically created and stored information is being used in depositions, to support motions, and at hearings and trials. Given the ways in which technology transforms how people communicate and do business, the “smoking gun” in a case—to the extent one exists—is more likely to be an e-mail, text message or social media post than a tangible document. Knowing how potential sources of digital evidence are created and stored, how to obtain that data in discovery, and how to maximize the value of that information during depositions and at trial are now critical components of the practice of law.

[4]       Digital evidence is so significant in discovery and litigation that it should be acknowledged as being much more than a subset of discovery, often referred to as “e-Discovery.” Existing and emerging technologies provide digital evidence that can shape the outcome of a case or investigation. Digital evidence from a wide range of technologies finds its way into civil and criminal litigation in the United States and other countries, with dramatic results. Digital evidence is poised to take on an even greater role in litigation as the Internet of Things continues to grow,[2] autonomous vehicles become commonplace,[3] industrial business operations incorporate drones,[4] and blockchain revolutionizes banking.[5]

[5]       This article discusses some of the reported cases in which digital evidence was the subject of motion practice, was introduced at trial, and was a determining factor in a case. It is not an exhaustive look at all the cases that have been affected by digital evidence, or all the kinds of technology that generate data relevant to legal proceedings. A review of the cases in this article, however, is sufficient to dispel any doubt about the importance of digital evidence and to confirm the magnitude of its impact on the practice of law. 

II. Connected Devices

A. Telematics Devices

 [6]       Telematics devices are wireless devices, typically installed in personal vehicles or fleet vehicles. They collect data on how the vehicle is being operated, if the vehicle crashes or an airbag is deployed, and when maintenance is needed.[6] These devices transmit that data from the vehicle to an entity, such as an insurance company or a fleet owner, in real time.[7]

[7]       Telematics data led to the criminal conviction of a driver in the United Kingdom who was involved in a hit and run accident that resulted in the death of a pedestrian in 2014.[8] Police experts analyzed data from the telematics device Omar Tariq was driving at the time of the accident, which showed that he was speeding—driving more than 20 miles over the posted speed limit.[9] Confronted with that evidence, Tariq pled guilty to causing a death by dangerous driving and was sentenced to more than three years in prison.[10]

[8]       In the United States, data from a Progressive Insurance telematics device helped a Cleveland, Ohio father persuade a jury that he was not guilty of murder.[11] Michael Beard was accused of suffocating his infant daughter on May 8, 2011 at 4:45 a.m., after he finished his shift working as a nursing aide.[12] Counsel introduced data from the Snapshot telematics device in his car at trial, and showed that Beard had turned the car off in front of the child’s house “at 4:44 a.m. and turned it back on three minutes later.”[13] After deliberating for an hour, the jury found that Beard was not guilty of the crime.[14]

[9]       Important leads in another criminal matter came from data from the UConnect telematics system in a stolen Jeep Renegade.[15] That evidence, in combination with footage from a Nest home security camera in the Jeep owner’s house, led to an arrest and assisted police in identifying the other thieves.[16] When a group of teenagers broke into the house of a Baltimore man, their faces were caught on the Nest camera in the house, which led to the arrest of one of the thieves.[17] He refused to identify his accomplices, who also stole the homeowner’s Jeep.[18] When the homeowner got his Jeep back, he noticed three new device names on the Jeep’s UConnect system paired device list.[19] The homeowner matched one of the device names to an Instagram account of a teenager who appeared to match one of the individuals seen on the Nest footage.[20] The homeowner also noticed that one of the names on the Instagram account’s contacts matched one of the phones on the list on the UConnect System.[21] This digital evidence gave Baltimore police several leads in the case.[22]

[10]     On the civil side, data from a telematics device enabled a driver in the United Kingdom to successfully challenge a speeding charge by contradicting the evidence that allegedly supported it.[23] Police charged Neil Herron with driving 10 miles over the posted speed limit.[24] Herron insisted that he had not been speeding.[25] At the time of the alleged speeding incident, Herron had been conducting a trial of a telematics device in his car.[26] The data from that device enabled Herron to prove that the car had been traveling far below the speed limit, as he had claimed.[27]

B. GPS Navigation Systems

[11]     Data from a GPS device[28] introduced in a criminal non-jury trial led to the conviction of a New Jersey man for second degree murder for intentionally running over a twelve year old girl.[29] Prosecutors alleged that George Ford killed the girl to prevent her from reporting what had happened to her when he was alone with her in the hours before her death.[30] Ford contended that he had hit the girl by accident after showing her horses he had in a pasture near Binghamton.[31] The critical evidence came from a GPS device that Ford’s estranged wife placed in his vehicle when she suspected he was having an affair.[32] When she provided the GPS device to the police, the data from the device showed that Ford had not been at the pasture and had spent the hours before the girl’s death behind an abandoned farmhouse half a mile from where she was killed.[33]

[12]     Similarly, in State v. Jackson, data from a GPS device installed by police proved to be key evidence leading to the conviction of defendant William Jackson for the murder of his daughter.[34] Jackson told police that his daughter had been kidnapped on her way to school.[35] After a search of Jackson’s house and truck failed to yield any evidence, police obtained a warrant and put a GPS tracking device in his truck.[36] Data from the GPS device led police to a storage unit, an empty grave near a logging road and a new grave where the girl was buried.[37] Based largely on the GPS data connecting Jackson to the body and its burial and reburial sites, the court convicted Jackson of murder and sentenced him to fifty-five years in prison.[38] The conviction was affirmed by the Washington Supreme Court.[39]

[13]     Ironically, in the case of a Wisconsin man, the evidence used to convict him of stalking his former girlfriend was the data from the GPS device he himself had used to commit the crime.[40] Paul Seidler previously installed a GPS tracking device on his ex-girlfriend’s car that tracked the car’s location and reported it to him by cellphone or computer through the Internet.[41] Seidler used the data to follow his ex-girlfriend.[42] Prosecutors used the data to support their case against him, describing the GPS device as “the best witness.”[43]

[14]     GPS data is also used as evidence in civil cases, such as the wrongful termination action brought by a cable company employee against his former employer, Pacific Bell Telephone Company.[44] Pacific Bell terminated Blake Smith’s employment after an investigation into the theft of his work truck led the company to conclude that Smith had failed to safeguard company property and that he had lied during the investigation into the theft.[45] Smith claimed he parked the truck, took the keys out of the ignition, and locked the truck.[46] A significant factor in Pacific Bell’s determination that Smith was lying was the data obtained from the GPS technology in the truck, which revealed that the truck was idling when it was stolen.[47] In an affidavit filed in support of its motion for summary judgment, Pacific Bell explained that the GPS technology in its trucks generates a report in a Microsoft Excel spreadsheet that records various data, including the time and location of every vehicle, each time the ignition is turned on or off, the time and location of the vehicle every seven seconds, and the time and location of the vehicle every one mile it is driven.[48] The Court ultimately granted Pacific Bell’s motion for summary judgment.[49]

C. Wearables[50]

 [15]     Digital evidence from wearable fitness trackers will play a role in a pending criminal case in Pennsylvania and a pending civil case in Canada. In West Chester, Pennsylvania, police arrested defendant Jeannine Risley when data from her Fitbit showed she lied to police when she reported she was assaulted.[51] Risley told the police officers responding to her 911 call that she was sleeping until around midnight, when she awoke to find a man on top of her.[52] She alleged that the man assaulted and raped her.[53] An examination of data from the Fitbit she wore that night, however, contradicted her claims.[54] The Fitbit data showed that Risley was awake and walking around at the time she claimed she was sleeping and ultimately assaulted.[55] Risley now faces trial on three misdemeanor counts including knowingly filing a false police report.[56]

[16]     On the civil side, a Canadian law firm is planning to use Fitbit data as evidence in a personal injury case to prove the effect that a car accident had on their client.[57] The accident victim, injured years before Fitbits were available, was a personal trainer and led an active lifestyle before the accident.[58] To support the plaintiff’s claim that her activity level is impaired by the accident, her lawyers intend to run data from the Fitbit she currently wears through an analytics platform which uses publicly available research to compare a person’s activity data with that of the general population.[59] Her lawyers expect the data to show that their client’s activity levels are now below average for a woman of her age and profession, as a result of the injuries she sustained in the accident.[60]

D. Dashboard Cameras and Red Light Traffic Cameras 

[17]     Data from dashboard video cameras and government operated traffic cameras is effective in both civil and criminal cases. Evidence from an onboard video camera, in addition to cell phone records, led to an Alabama jury awarding nearly $1.3 million to a driver who was severely injured in a crash caused by a truck driver who was distracted by a work-related phone call at the time of the accident.[61] At trial, the jury saw video footage from a camera that was in the school bus with which Michael Duey collided.[62] Additional digital evidence from cell phone records from the truck driver Gregory Moore, whose negligence caused the collision, showed Moore was on a business call at the time of the accident.[63] Based on this data, the jury found Moore and his employer liable for the damages incurred by Duey.[64]

[18]     In a criminal case in California, the court convicted Carmen Goldsmith of failing to stop at a red light in an intersection, based on photos and video generated by a red light traffic camera system.[65] At trial, a police investigator testified that this computer based digital camera system records events that occur in an intersection after the traffic light turns red, and stores the information on the hard disc of a computer at the scene.[66] Technicians retrieve the data during the day via an Internet connection.[67] The system records and produces three photos and a twelve-second video.[68] The photos show the vehicle approaching the intersection before the violation, then the vehicle within the intersection turning right or going through the intersection, and finally the vehicle’s license plate.[69] The system puts a data bar on all three photos showing the date, time, location and amount of time the traffic light was red at the time of the photo.[70] In this case, the video shows the vehicle approaching the intersection and moving through it.[71] The Appellate Division of the Superior Court, the Court of Appeals, and the California Supreme Court all affirmed Goldsmith’s conviction. In response to Goldsmith’s claim that the camera evidence was not adequately authenticated, the Supreme Court explained that it frequently approved the “substantive use of photographs as essentially a ‘silent witness’ to the content of the photographs,” because to “hold otherwise would illogically limit the use of a device whose memory is without question more accurate and reliable than that of a human witness.”[72]

E. Event Data Recorders

[19]     Data from event data recorders, also known as black boxes, proves to be important evidence in criminal cases. In Commonwealth v. Zimmerman, the Massachusetts Appellate Court held that the trial judge properly admitted evidence taken from the event data recorder (EDR[73]) in the defendant’s car, which contributed to her conviction for motor vehicle homicide.[74] Michelle Zimmerman lost control of her SUV and it spun, sliding off the road, hitting a tree, and resulting in the death of the passenger in the front seat of her vehicle.[75] At the time of the accident, road conditions were poor, with both rain and snow.[76] The police accident investigator found there was probable cause to believe that “evidence of this crime would be found in the EDR.”[77] While Zimmerman claimed she was driving between 20 and 30 miles per hour, the data from the EDR in her vehicle showed that five seconds before the accident, she was driving at 58 miles per hour.[78] Zimmerman was charged with and convicted of operating her vehicle at a rate of speed that was not reasonable or prudent and criminally negligent operation of a vehicle.[79]

[20]     In Matos v. State, the Florida District Court of Appeal affirmed the conviction of Edwin Matos on two counts of vehicular manslaughter where the key issue in the case–the speed at which Matos had been driving–was established by the prosecution through data from an EDR.[80] Matos collided with another vehicle, killing two teenage girls.[81] Data from the EDR in Matos’s car showed he was driving at a 114 miles per hour (in a 30 mile per hour zone) four seconds before the crash, and 103 miles per hour within one second after the crash.[82] The defense’s expert estimated the car’s speed at only 56.91 miles per hour.[83] Data from the EDR helped the court to convict Matos.[84]

[21]     Similarly, in People v. Hopkins, data from the air bag module in the defendant’s car helped prosecutors establish “a prima facie case of depraved indifference murder” and defeat the defendant’s motion to dismiss the indictment.[85] The air bag module data showed that at the time of impact, the defendant’s vehicle was going between 65 and 70 miles per hour; that five seconds before impact, the defendant’s car was travelling at 104 miles per hour; and that three to four seconds before impact, the vehicle was going 106 miles per hour.[86] The posted speed limit in the area was 30 miles per hour.[87] The data further showed that the defendant did not apply the brakes until two and a half to three second before he crashed into the line of cars stopped at a red light.[88]

F. E-Z Pass Transponders

[22]     The E-Z Pass system, implemented in toll plazas in sixteen states, collects data used by both prosecutors and defendants in states like New Jersey. In S.S.S. v. M.A.G., a New Jersey appellate court reversed the lower court’s entry of a final restraining order in a domestic violence case and remanded the case for a new trial due to the improper exclusion of E-Z Pass evidence.[89] In this case, a woman alleged her former boyfriend picked her up at her school at Rutgers-Newark at 9 A.M., assaulted her at a Jersey City motel at 9:30 A.M., and returned her to her school at 10 A.M.[90] The defendant denied this and claimed that nothing had happened.[91] In addition to a letter from his employer stating he had been at work from 8:35 A.M. until 5 P.M., he also offered data from E-Z Pass transponder records, showing that he crossed the Bayonne Bridge in to Brooklyn at 8:16 A.M. that day.[92] The defendant argued that he could not have crossed the bridge into Brooklyn at 8:16 A.M., gotten to work at 8:35 A.M., and been in Newark at 9 A.M.[93] The appellate court found that in this he-said-she-said dispute, where no witnesses could be called or exhibits introduced, the E-Z Pass transponder evidence was critical to the defense and its exclusion on hearsay grounds was improper.[94]

[23]     In State v. McGuire, the prosecutor introduced E-Z Pass transponder data against Melanie McGuire, a New Jersey woman accused of killing her husband, cutting up his body, and disposing of it in suitcases in Virginia.[95] The prosecution introduced the evidence to support the allegation that she traveled from her home to Atlantic City in order to create false evidence showing that her husband was still alive and in the Atlantic City area.[96] McGuire had called E-Z Pass customer service trying to get them to remove two forty-five cent charges showing her traveling near Atlantic City, which she claimed were incorrect.[97] The prosecution also introduced E-Z Pass evidence from the vehicles of McGuire and her parents.[98] This data, in combination with the state’s case, suggested that on May 3, McGuire picked up her kids from day care, dropped them off with her parents, and then returned to her house to get the suitcases containing her husband’s body and travel to Delaware and Virginia to dump them.[99]

III. Social Networking Sites

[24]     Not only does the widespread use of social networking sites create new ways for individuals and businesses to communicate, but it also creates a treasure trove of relevant data for civil and criminal litigation. For example, in Reid v. Ingerman Smith LLP, Reid sued her employer and Mary Anne Sadowski for damages resulting from alleged sexual harassment by Sadowski.[100] Defendants sought production of postings and photographs from private portions of Reid’s Facebook account, arguing that since postings and photographs on the public portions of her account contradicted her claims in the lawsuit, the private portions may also contain relevant information.[101] After reviewing the public postings, the Court found them to be probative evidence of Reid’s mental and emotional state, and concluded that her private postings may also contain relevant information that reflected her emotional state.[102] The Court also found that postings by third parties about Reid’s social activities were discoverable, as they could be relevant to her claims of emotional distress and loss of enjoyment of life, and could reveal the names of potential witnesses in the case.[103] Reid was ordered to produce social media postings and photographs that “reveal[ed], refer[ed], or relate[d] to any emotion, feeling or mental state… [and] relate[d] to events that could be reasonably expected to produce a significant emotion, feeling or mental state,” including posts made by third parties that contain their observations of Reid and Reid’s responses to those posts.[104]

[25]     Similarly, in Romano v. Steelcase, Inc., the court required the plaintiff to provide the defendant with access to her Facebook and MySpace pages and accounts, as they were deemed to contain information relevant to her damages claims and to the extent of her alleged injury, including her claim for loss of enjoyment of life.[105] The plaintiff alleged that she was permanently injured as a result of the accident and could not participate in certain activities due to her injuries.[106] The defendant argued that information on the public pages of plaintiff’s Facebook and MySpace pages showed her to have an active lifestyle, and that one account contained a photo of the plaintiff smiling outside her home–even though she claimed that she was bedridden and confined to her house as a result of her injuries.[107] The contradictions between the information on the public portions of these social media sites and plaintiff’s claims in her lawsuit led the Court to find it was reasonably likely that the private portions of those sites may contain additional information relating to her activities and enjoyment of life, which were relevant and material to the defense of the case.[108]

[26]     In Held v. Ferrellgas, Inc., a recent employment discrimination and retaliation case, the Court found that data from the online job search engines that the plaintiff had used were relevant and had to be produced.[109] Defendants argued that any job searches conducted during the course of plaintiff’s employment related to his commitment to his job, his perspective on the working environment at the company, and any emotional distress he allegedly suffered.[110] Searches conducted after his employment ended, defendants contended, related to plaintiff’s alleged emotional distress, actual damages and attempts to mitigate his alleged damages.[111] The court ultimately agreed with the defendants.[112]

[27]     Being equally probative in criminal matters, postings and communications on Facebook played a role in the conviction of several men on terrorism conspiracy charges in U.S. v. Hassan.[113] The prosecution used the defendants’ Facebook postings and communications to demonstrate their violent tendencies and commitment to terrorism.[114] At trial, the prosecution’s evidence included messages posted by one defendant on Facebook promoting his radical Jihadist beliefs; another defendant’s postings on Facebook and other social media sites that demonstrated his belief in violent jihad and his willingness to further violent causes; and information showing that the second defendant had asked someone to delete the postings that related to his violent ideology.[115] The defendants were convicted of conspiracy to provide material support to terrorists and other charges.[116] Their convictions were affirmed by the Fourth Circuit Court of Appeals.[117]

IV. Text Messages and Tweets 

[28]     Digital evidence played a central role in the criminal trial of Dharun Ravi, a Rutgers college student charged with witness tampering, invasion of privacy, and bias intimidation arising from his activation of a webcam to watch his roommate’s date with a man in their dorm room.[118] The evidence of Ravi’s witness tampering included a series of text messages he sent to fellow Rutgers student Molly Wei while police interviewed her.[119] Those texts showed that Ravi tried to influence what Wei told the police about their spying on his roommate.[120] In one text message, Ravi wrote: “Did you tell them we did it on purpose? What did you tell them when they asked why we turned it on? I said we were just messing around with the camera.”[121] After the trial, where Ravi was convicted of witness tampering, one juror stated that Ravi’s texts convinced her that he had tampered with a witness.[122]

[29]     Texts and tweets were also important evidence introduced at trial in connection with the invasion of privacy and bias intimidation charges.[123] In a Tweet from Ravi to another student, he wrote: “Roommate asked for the room. I went to Molly’s room and turned on my webcam I saw him making out with a dude. Yay.”[124] In another Tweet, Ravi invited others to view video of his roommate during another date with the same man, saying “[a]nyone with iChat I dare you to video chat me between hours of 9:30 and 12. Yes it’s happening again.”[125] In an attempt to persuade the jury that he was not biased against gay people, Ravi’s attorney introduced a text Ravi sent to his roommate where Ravi wrote “I’ve known you were gay and I have no problem with it. In fact one of my closest friends is gay and I have a very open relationship.”[126] The jury found Ravi guilty on those charges as well.[127]

V. Blogs and Chat Rooms 

[30]     Litigants also rely on blog entries and chat room transcripts to support their claims in civil cases. Portions of a blog were among the evidence a father used to support his motion for a new trial in a divorce case, after a Louisiana trial court awarded domiciliary custody of his minor son to his ex-wife.[128] The father unsuccessfully relied on pages of his ex-wife’s blog to argue that she may have had a relationship with another man during the couple’s separation, despite having denied that she was in a relationship during the trial.[129] He further argued that his ex-wife’s blog entries showed she spent an excessive amount of time on the Internet rather than taking care of her child, and that she hated his parents because she accused them of cyberstalking her by reading her blogs.[130] The trial judge stated that while the Internet statements were evidence that could have been used to impeach the ex-wife’s credibility during the divorce proceeding, the statements occurred after the trial and were not made under oath, and therefore, did not provide the basis for a new trial.[131] The Court also noted that, more generally, it was not clear that the statements would be evidence that was important to the case.[132] The appellate court affirmed the trial court’s order.[133]

[31]     Conversely, other courts have found chat room transcripts to be relevant evidence. In Glazer v. Fireman’s Fund Insurance Company, the plaintiff was ordered to produce copies of all her chats from LivePerson, a website offering online advice and professional consulting services, including sessions with online psychics.[134] Glazer chatted with the online psychics on numerous occasions, and e-mailed portions of some of those online chats to her work e-mail account.[135] When she sued Fireman’s Fund for allegedly retaliating against her after “she complained about discrimination against non-African Americans and [ultimately terminating] her because of her religion,” Fireman’s Fund reviewed the excerpts of the chats and sought to obtain the transcripts of all chats in discovery.[136] Based on a review of the excerpts, the Court agreed with Fireman’s Fund that all the chats appeared to be relevant to one or more issues in the case—such as Glazer’s work performance, her relationships with her co-workers, her opinions about how she was treated during her employment at the company, her emotional state before, during, and after her employment, the steps she took to mitigate her damages, and her personal beliefs about African Americans—and allowed them to be discoverable.[137]

VI. E-mails

[32]     While there is a myriad of other digital evidence sought in building cases, perhaps the most frequently sought and used form of digital evidence is e-mail. In Arroyo v. Volvo Group North America, LLC, a military service discrimination and disability discrimination case, e-mail evidence led to the reversal of an order granting summary judgment to Volvo.[138] The Court found that e-mails sent between Volvo employees could lead a reasonable jury to conclude that Volvo had anti-military animus against Arroyo, and discriminated against her because she had post-traumatic stress disorder.[139] The Seventh Circuit Court of Appeals found that the District Court underestimated the “strength of the emails as support for Arroyo’s case.”[140]

[33]     In those e-mails, Volvo supervisors expressed frustration with Arroyo’s taking time off from work for military service, writing “are we required to give her the day before and day after for travel?” and “I find myself with a dilemma if I were to discipline a person for taking too much time off for military reserve duty․ I certainly give her credit for serving our country but of course I am also responsible for our business needs.”[141] During Arroyo’s deployment to Iraq, her supervisor sent an e-mail to Volvo’s head of labor relations complaining that Arroyo had contacted him only once since she deployed, stating that for scheduling purposes, “it would be beneficial for us to know her status.”[142] Responding to that concern, the head of labor relations wrote in another e-mail that “[u]nfortunately, there isn’t a lot we can do. Per the law we have to wait for her. Sorry it isn’t what you wanted to hear.”[143]

[34]     Internal e-mails from Volvo personnel also provided support for Arroyo’s disability discrimination claim.[144] One such e-mail showed that Volvo considered disciplining Arroyo for being absent while she was hospitalized for her post-traumatic stress disorder, even though she previously advised Volvo of her disabling condition.[145] In another e-mail, one of Arroyo’s supervisors joked about her absence, writing that there were “several rumors for [Arroyo’s] not being here,” including that “[s]he’s on vacation in Hawaii.”[146] In yet another e-mail, a Volvo employee opined that Arroyo was “really becoming a pain with all this.”[147] 

VII. Conclusion 

[35]     Digital evidence has disrupted discovery, civil and criminal litigation, and the practice of law. Advances in technology radically changed the way in which information is created, transmitted, preserved, and accessed–as well as the way in which potential litigants communicate. Technological innovation altered the types of claims that are litigated, the way in which they are litigated, and the kinds of evidence that must be used to support and undercut those claims.

[36]     There is no turning back. The days of document production consisting primarily of paper and of hard-copy trial exhibits sitting on easels in front of juries are behind us. When asked to find information about an opposing party, the initial inclination of lawyers who have recently graduated from law school and entered the practice of law will be to check social media to obtain information about that party. To investigate the allegations in a complaint, these lawyers’ first instinct will be to search the e-mails on the client’s office computer and their messages on cell phones and tablets. All lawyers must acknowledge that digital evidence plays an important role in litigation. Those who fail to understand the relevance of technology and digital evidence to the practice of law do so at their—and their clients’—peril.

[37]     The cases discussed in this Article illustrate why lawyers need to stay abreast of changes in technology and be knowledgeable about sources of data they create.[148] To competently and effectively represent their clients, lawyers need to know which digital evidence may be relevant in a particular case, what they should request from the opposing party in discovery, the proper way in which to craft those requests, how to confirm that what they received is what they requested, how to use digital evidence in depositions, as well as how to authenticate digital evidence at trial and overcome potential objections to its admissibility.

[38]     As the widespread adoption of new technology continues, and more companies, industries, and governmental entities recognize the transformative power of big data and analytics, the volume of data that will be relevant in litigation will increase exponentially. The frequency with which digital evidence will be used in litigation, in government investigations and administrative proceedings, and at civil and criminal trials will soar. It will become clear to lawyers and clients that gaining competence, if not expertise, in the use of digital evidence is not a necessary evil, but a way to enhance the litigation strategy for a case and to increase the likelihood of a successful resolution. The ubiquity of digital evidence means that litigation and data are inextricably intertwined and that mastering “connected” discovery and maximizing the value of digital evidence are critical skills for today’s lawyers.

As documents are increasingly maintained electronically, it has become easier to delete or tamper with evidence (both intentionally and inadvertently) and more difficult for litigants to craft policies that ensure all relevant documents are preserved. This opinion addresses both the scope of a litigant’s duty to preserve electronic documents and the consequences of a failure to preserve documents that fall within the scope of that duty.”).

[50] Wearable devices contain smart sensors and wirelessly connect to smartphones through a web connection. These devices collect and track data about the person who wears them, such as activity level, heart rate, calories burned and sleep patterns. They can also be used to make payments at stores and to alert the wearer about incoming calls and e-mails. Popular types of wearables include fitness trackers, smartwatches, smart glasses, smart clothing and smart jewelry. See Dan Sung, What Is Wearable Tech?

[51] A Fitbit is a fitness tracker that allows the wearer to monitor things such as the number of steps taken, distance covered and calories burned. Some versions include an altimeter, which keeps track of the amount of stairs climbed and some include sleep tracking. The Fitbit syncs to the wearer’s Fitbit account through a computer or mobile device and enables the wearer to view the activity data collected by the wearable device. See Robert J.

[73] An Event Data Recorder (EDR), also known as a “black box,” is a device that is built into a vehicle’s airbag control module and records certain information from a vehicle immediately before and/or during most crashes. The data from the event data recorder’s memory can be downloaded to provide information about what happened to the vehicle, the deployment of airbags and seat belt tensioners, as well as data about the engine speed and vehicle speed prior to the crash.
