    Technology Expert Allowed to Testify Despite Not Using the Software Systems at Issue

    Plaintiffs Donna Wood, Caelan Doherty, Max Goldstein, Bridget Logan, James Kyle Newman, Lakisha Watson-Moore, Tristan Angulo, Alexandra Marie Wheatley-Diaz, Robin Ceppos, and Nick Coker (together, “Plaintiffs”), individually and on behalf of all others similarly situated, bring this collective and class action against Mike Bloomberg 2020, Inc. (the “Campaign” or the “Defendant”), asserting claims under the Fair Labor Standards Act (the “FLSA”) and state labor laws.

    In November 2019, Michael Bloomberg announced his candidacy for President of the United States. The Campaign’s purpose was to advance Bloomberg’s presidential candidacy. Plaintiffs worked as Field Organizers (“FOs”) and “were tasked with primarily conducting phone calls and door-to-door canvassing with potential voters in the day-to-day functional work of the Campaign.”

    Plaintiffs offered testimony from Jonathan Jaffe as an expert witness to establish that Plaintiffs communicated data in interstate commerce so as to be individually covered by the FLSA.

    The Campaign presented arguments regarding the admissibility of his testimony under Rule 702 and Rule 403.

    Technology Expert Witness

    Jonathan Jaffe is a technology consultant, data scientist, software developer, and the founder and owner of Its-Your-Internet, an advanced technology software and general litigation support consulting firm, established in 2008.

    His areas of expertise include “how the interne works, how a data center works, how we code things, how these apps work, [and] how these applications work,” and he has testified as an expert in numerous other matters.

    Discussion by the Court

    Jaffe opined that “Plaintiffs and opt-in Plaintiffs transmitted data and information across state lines using the NGP Van system” and “the Thru Talk system.”

    Jaffe describes how, based on the material he reviewed, data that Plaintiffs collected would cross state lines (1) when it was stored in a single, national database located in another state, and (2) when it was aggregated to be viewed by employees in the Campaign’s headquarters in New York.

    He relied on evidence that FOs collected voter data and inputted that data into VAN and ThruTalk. Jaffe noted that, in order to transmit the data they had collected across state lines for storage in a database located in another state, Plaintiffs either manually clicked a button to “sync” or enabled an “auto-sync” feature in the software. 

    Jaffe compares the “function of the underlying system” to “a long-distance phone call [by which] an individual would not physically transport their voice across state line[s] [but] effected the transmission of their voice across state lines by dialing the number” or “mailing a package through UPS or FedEx” whereby a delivery person, rather than the sender, physically transports the package. 

    Rule 702

    The Campaign insists that Jaffe’s analysis merely “addresses an entirely different question: whether data and information that was entered in VAN and ThruTalk by Plaintiffs crossed state lines at all, at any point, by operation of the equipment being used, without consideration of whether Plaintiffs were responsible for the purported transmission.”

    The Campaign’s highly technical relevance argument—that “whether Plaintiffs transmitted data” with a specific action is a different question from whether “the software’s internal workings” or a “headquarters request for information from another state” caused the data transmission —is not supported by the case law.

    The Court stated that none of the cases cited by the Campaign establish a causation requirement for individual FLSA coverage.

    The Campaign next insists that Jaffe’s conclusions are unreliable because his “opinions and testimony are based on insufficient facts and data, and they are the product of inappropriate speculation.”

    The Court found that the Campaign’s argument, namely that “Jaffe admittedly never used the software systems at issue, and he also lacked the information required to establish that all Plaintiffs used the software systems,” does not satisfy this high bar.

    While Jaffe never used the software systems at issue, he “utilized [his] 25 years expertise and experience with developing, expanding, and evaluating Enterprise level software systems.”

    The Campaign’s assertion that Jaffe’s opinions lack reliability because “he did not confirm that all Plaintiffs used the VAN and/or ThruTalk software” and “did not have the data required to make determinations regarding the number of days that Plaintiffs may have transmitted data across state lines, the amount of time in each day that Plaintiffs may have spent transmitting data across state lines, or the volume of data that Plaintiffs may have transmitted across state lines” was likewise rejected by the Court.

    Rule 403

    The Campaign first argues that Jaffe’s opinions and testimony are not relevant within the meaning of Daubert  “because they will not assist in understanding or resolving the issue of Plaintiffs’ alleged individual FLSA coverage.” 

    However, Jaffe’s conclusions that “Plaintiffs and opt-in Plaintiffs transmitted data and information across state lines using the NGP Van system” and “the Thru Talk system” are plainly relevant to the question of whether Plaintiffs’ work involved the use of instrumentalities for communication across state lines.

    The Campaign’s argument that “Jaffe fails to present information and opinions that would assist the jury in resolving whether Plaintiffs transmitted data across state lines and whether they did so on a regular and recurrent basis, and he instead opines on whether data was transmitted across state lines at all, without consideration of whose actions caused the transmission or the frequency of transmission” does not present a danger of misleading the jury.

    Basically, Jaffe does not opine on the ultimate legal issue—whether Plaintiffs are individually covered under the FLSA.

    Held

    The Court denied the Campaign’s motion to exclude the opinions and testimony of Jonathan Jaffe.

    Key Takeaway:

    While Jaffe never used the software systems at issue, he “utilized [his] 25 years expertise and experience with developing, expanding, and evaluating Enterprise level software systems.” Moreover, Jaffe’s conclusions are plainly relevant to the question of whether Plaintiffs’ work involved the use of instrumentalities for communication across state lines.

     The Campaign’s arguments, therefore, go to the weight, rather than the admissibility, of the opinion in connection with the determination of whether Plaintiffs have met their burden to establish individual coverage under FLSA.

  • Technology Expert Witness’ Analysis of Call Detail Records Admitted

    Technology Expert Witness’ Analysis of Call Detail Records Admitted

    This case concerns Defendant’s alleged transmission of illegal robocalls. Plaintiff, Office of the Attorney General, State of Florida, Department of
    Legal Affairs brought this action pursuant to the Telemarketing and
    Consumer Fraud and Abuse Prevention Act. Apparently, Smartbiz courts
    robocaller customers by allowing them to place a high volume of calls in quick
    succession, billing only for the duration of completed calls – sometimes in as little as .6 second increments and ignoring clear indicia of fraudulent call traffic.

    Plaintiff retained Mike Rudolph “as an expert witness to analyze several relevant datasets, specifically: Defendant’s Call Detail Records (“CDRs”), consumer voicemail recordings provided by YouMail, traceback data provided by the Industry Traceback Group (“ITG”), and consumer complaint data provided by the Attorney General.” 

    Defendant filed a motion to strike Rudolph’s expert testimony “because it does not carry the hallmarks of reliability.”

    Defendant argued that Rudolph’s testimony and methods are unreliable because they are based on confidential and proprietary processes, use algorithms and codes to do much of the work, have not been peer reviewed, have an error rate of less than 1% that is inherently suspect, and cite the average length of Defendant’s calls as a metric.

    Technology Expert Witness

    Mike Rudolph is the CTO and Chief Architect of YouMail’s telephony, cybersecurity, and robocall mitigation platforms. Rudolph works directly with Fortune 500 organizations, service providers, and working groups, employing AI, machine learning, and forensic analytics to combat illegal and unwanted calls. Moreover, Rudolph holds over a dozen patents featuring a number of startups and public companies adding intelligence through AI and expert systems to highly scaled platforms in communications, compliance and governance, business process management, activity monitoring, background checks, and consumer advertising.

    Discussion by the Court

    Rudolph prepared an Expert Report describing several types of analysis using different methodologies including the following:

    • First, is the behavior call analysis which identifies indicia of fraudulent or otherwise unwanted calls in Defendant’s CDRs and consists of five sections of his Summary of Findings: (1) Analysis of “Snowshoeing” Calling Tactics, (2) Analysis of Low Answer Rates and Short Duration Calls, (3) Analysis of Phone Number Spoofing, (4) Analysis of Recipient Geographic Location, and (5) Analysis of Telemarketing Hours and Do-Not-Call-Registry (DNC) Data.
    • Next, Rudolph analyzed Defendant’s CDRs in conjunction with YouMail Consumer Voice Call Evidence, which consists of call records for calls to YouMail subscribers, recordings of voicemails left by those calls, and transcriptions of those voicemails, identifying examples of calls that Defendant transmitted to YouMail subscribers; third, Rudolph performed an analysis of traceback information to identify patterns in Defendant’s traceback responses to the ITG.
    • Finally, Rudolph analyzed Defendant’s CDRs and YouMail data in conjunction with consumer complaint data supplied by Plaintiff to identify individuals who complained about the types of calls Defendant transmitted. 

    According to Plaintiff, Defendant’s contentions that Rudolph’s methods are unreliable because they use algorithms and have not been peer reviewed are not relevant to the type of expert opinion Rudolph has produced. Defendant relies primarily on factors relevant to scientific testimony to rebut the reliability of Rudolph’s methodology, but Rule 702 does not bar non-scientific expert evidence, and allows expert opinions based on technical or other specialized knowledge.

    This Court found that Defendant’s issues with Rudolph are insufficient to warrant the exclusion of his testimony and are best addressed on cross-examination.

    Held

    The Court denied the Defendant’s Daubert motion to exclude the testimony and report of Mike Rudolph.

    Key Takeaway:

    Rudolph submitted a comprehensive expert report on the relevant datasets, which the Court admitted because the Defendant’s arguments against it were unpersuasive. It was held that the expert’s opinions should not be excluded, but rather be subjected to “vigorous cross-examination” and “presentation of contrary evidence.
