Notes Re: EVIDENCE

Recent revisions to the Federal Rules of Civil Procedure have focused 
on the discovery and production of electronically stored information. 
As alluring as the promise of discovering a smoking-gun e-mail is, 
such an e-mail only becomes useful in litigation if it can surmount a 
series of evidentiary hurdles that all too often receive only scant 
attention and, in many cases, are overlooked entirely. 

The latter was the case in Lorraine v. Markel American Ins. Co.
[FOOTNOTE 1] On the night of May 17, 2004, lightning struck Jack 
Lorraine's yacht, Chessie, as it sat at anchor in Chesapeake Bay. 
Chessie's hull sustained serious damage, which ultimately led to 
Lorraine and his insurance company, Markel, contesting the scope of 
an arbitration agreement into which both had earlier entered. 

Appearing before Chief Magistrate Judge Paul W. Grimm in the U.S. 
District Court for the District of Maryland, both Lorraine and Markel 
moved for summary judgment, each relying heavily on e-mail exchanges 
appended to their respective motions. Neither party, however, made 
any effort to authenticate the e-mails. Nor did they consider, let 
alone address, any of the hearsay issues raised by these e-mails. The 
parties also ignored the potential implications of the original 
writings rule. 

This utter disregard for these evidentiary issues led the magistrate 
judge to dismiss both motions. It also prompted him to issue a 50-
page opinion that reads as part cautionary tale and part primer on 
evidentiary issues related to e-discovery. In addition to providing a 
general reminder that the rules of evidence apply to electronically 
stored information (ESI), the decision highlights some areas of the 
rules of evidence that are particularly important for litigators to 
keep in mind when dealing with ESI. 

The rules of evidence relating to authenticity are among the 
principal obstacles to admission of an electronic document into 
evidence. Paper documents, some courts have reasoned, can be examined 
for signs of physical alteration or forgery. Electronic documents, by 
contrast, are more easily modified without readily apparent signs of 
alteration. And while some courts therefore have scrutinized 
electronic documents more carefully, the requirements under the 
Federal Rules of Evidence for authentication of electronic and "hard 
copy" documents are one and the same. 

The general authentication provision, Rule 901(a), requires only that 
the party moving to introduce the document into evidence 
show "evidence sufficient to support a finding that the matter in 
question is what its proponent claims." Though this is not a 
particularly exacting standard, Magistrate Judge Grimm noted 
that "counsel often fail to meet even this minimal showing when 
attempting to introduce ESI, which underscores the need to pay 
careful attention to this requirement."[FOOTNOTE 2] Such a 
potentially fatal mistake can be avoided with a bit of care and 
forethought. 

Rule 901(b) sets out a non-exclusive, illustrative list of methods by 
which evidence can be authenticated. While some methods, like 901(b)
(2), which allows for authentication by nonexpert opinion on 
handwriting, are unlikely to be useful when dealing with ESI, other 
authentication techniques are particularly well suited to ESI and 
should be given careful consideration when preparing to authenticate 
(or oppose the authentication of) an electronic document. 

Authentication through testimony 

Rule 901(b)(1) allows authentication through testimony by a witness 
with knowledge "that a matter is what it is claimed to be." At its 
most straightforward, such a witness could be the author of the 
exhibit. In the alternative, the authenticating witness could be a 
non-drafter with "personal knowledge of how that type of exhibit is 
routinely made," which generally requires the witness to be able to 
testify with specificity about the process by which the ESI is 
created, acquired, maintained and preserved without alteration or 
change. On the other hand, "boilerplate, conclusory statements that 
simply parrot the elements of the business record exception to the 
hearsay rule ... or public record exception" will not suffice.
[FOOTNOTE 3] 

Circumstantial authentication 

Rule 901(b)(4) is the most common method for authenticating e-mail 
and other electronic records. This rule allows for authentication 
by "appearance, contents, substance, internal patterns or other 
distinctive characteristics, taken in conjunction with 
circumstances." Under this rule, an e-mail can be authenticated by, 
for example, considering the e-mail address of the purported sender 
and the fact that the apparent author would have been familiar with 
the content of the e-mail. 

Preparing for circumstantial authentication 

Clients concerned about ensuring that they will be able to introduce 
their own ESI in future litigation can plan ahead to make use of Rule 
901(b)(4) by adopting a system of assigning "hash values" to finished 
documents. 

A "hash value," or "hash mark," is a series of numbers created by 
applying characteristics from a specific file to a standard 
mathematical algorithm. The resulting number is unique and can serve 
as that file's "digital fingerprint." In addition to allowing for 
relatively straightforward authentication of legitimate documents, 
hash values also can help guard against opponents attempting to 
introduce earlier versions of a document as final.[FOOTNOTE 4] 

Authentication by comparison 

Another frequently used method of authenticating ESI is set out in 
Rule 901(b)(3), which allows for authentication by comparison of the 
proposed evidence with an already authenticated document, either by 
an expert witness or the trier of fact. Several courts have held that 
e-mails that cannot be authenticated otherwise may be authenticated 
by having the fact finder compare the e-mails with specimens 
authenticated by other methods, such as those discussed above and 
below.[FOOTNOTE 5] 

Self-authentication 

Some documents are self-authenticating under Rule 902. One category 
of documents for which self-authentication is permitted in particular 
should be given special consideration when dealing with ESI. Rule 902
(7) allows self-authentication for documents that bear "inscriptions, 
sign, tags or labels purporting to have been affixed in the course of 
business and indicating ownership, control, or origin." Though this 
has not been frequently litigated,[FOOTNOTE 6] this rule may permit 
authentication of business e-mails with "information showing the 
origin of the transmission and identifying the employer-
company."[FOOTNOTE 7] Thus, an automatic signature at the end of an e-
mail may be enough for self-authentication. 

HEARSAY 

After ESI evidence has passed the authentication hurdle, counsel must 
then consider whether there are any hearsay issues. 

The first issue to consider is whether the electronic information 
sought to be introduced is hearsay at all. Hearsay is an out-of-court 
statement made by a declarant and offered for the truth of the matter 
asserted. 

Under Rule 801(a), a "statement" is "(1) an oral or written assertion 
or (2) nonverbal conduct of a person, if it is intended by the person 
as an assertion." A "declarant" is "a person who makes a statement." 
Notice that both of these definitions specifically refer to 
a "person." 

This has the effect of excluding anything automatically generated by 
a computer. So, for example, a time stamp automatically added to an e-
mail showing the date and time at which it was sent would be outside 
the definition of hearsay. Though there could still be evidentiary 
issues related to the e-mail, the hearsay rule should not bar the 
time stamp from being introduced into evidence for the truth of the 
matter asserted (i.e., that it was sent when the timestamp says it 
was). 

If an electronic document is hearsay, consideration should be given 
to whether any exceptions to the hearsay rule might apply. Courts 
continue to define how the contours of the hearsay exceptions apply 
to ESI. Many of the exceptions, as well as the exclusions from the 
definition of hearsay, are applied to ESI in a wholly conventional 
matter. 

The admission of the party-opponent exclusion under Rule 802(d)(2)
(A), for example, is applied to e-mails made by a party in the same 
way that it would be to a verbal statement or a handwritten note.
[FOOTNOTE 8] There are other hearsay exceptions, however, to which 
careful thought should be devoted in the context of ESI. 

BUSINESS RECORDS EXCEPTION 

The "business records" exception to the hearsay rule allows the 
admission of a document that was made in the normal course of 
business, at or near the time of the events it records, and that was 
based on either the personal knowledge of the author or a person who 
had a business duty to transmit that information to the author. 

Given the overwhelming predominance not only of e-mail, but also 
electronic record-keeping in many industries, it is not surprising 
that this is one of the most frequently argued hearsay exceptions 
when the admissibility of electronic evidence is at issue. 

Courts, however, have not been uniform in their application of the 
business records exception. Some jurisdictions, for example, have 
required each e-mail in an e-mail chain to independently satisfy the 
business records exception, or some other exception, in order to be 
admissible. Other courts have been more lenient, admitting e-mail 
chains as a whole and leaving for the jury the ultimate question of 
trustworthiness.[FOOTNOTE 9] 

NOVEL HEARSAY EXCEPTIONS 

Because e-mails tend to be much more informal than other writings 
and -- with the proliferation of BlackBerries and other hand-held e-
mail devices -- are written from just about every place imaginable, 
courts have begun to consider the use of hearsay exceptions that have 
not typically been used for other writings. 

Present sense impression 

Rule 803(1) allows admission of a statement that would otherwise be 
excluded by the hearsay exclusion if it is a "present sense 
impression." The rule defines a present sense impression as "a 
statement describing or explaining an event or condition made while 
the declarant was perceiving the event or condition, or immediately 
thereafter." Though courts have not yet had much opportunity to 
consider this question,[FOOTNOTE 10] it is not difficult to imagine 
scenarios in which this rule could be successfully used as the basis 
for admission of an e-mail or text message describing an ongoing 
event. 

Excited utterance 

Closely related to the present sense impression exception is the 
excited utterance exception. Rule 803(2) sets out a hearsay exception 
for "a statement relating to a startling event or condition made 
while the declarant was under the stress of excitement caused by the 
event or condition." Thus far no court that has considered this rule 
in the context of an e-mail or text message has found it applicable. 
Nor have those courts held, however, that e-mails, as a category, are 
incapable of satisfying the excited utterance exception. The courts 
that have considered the question instead have merely determined 
that, in the particular circumstances of those cases, the e-mails in 
question did not qualify as excited utterances.[FOOTNOTE 11] 

Then-existing mental, emotional or physical condition 

Rule 803(3) provides a hearsay exception for "a statement of the 
declarant's then existing state of mind, emotion, sensation, or 
physical condition (such as intent, plan, motive, design, mental 
feeling, pain and bodily health)." Like the present sense impression 
and excited utterance exceptions, the requirement of a 
contemporaneous statement makes this exception particularly well-
suited to the quickly written, off-the-cuff nature of many e-mails.
[FOOTNOTE 12] 

ORIGINAL WRITINGS RULE 

The "original writings" rules require that an original writing, 
recording or photograph be provided in order to prove its contents.
[FOOTNOTE 13] 

A duplicate is also admissible, however, unless a genuine question is 
raised as to the authenticity of the original or it would be unfair 
to admit the duplicate. Because courts have typically found that 
the "original" of information stored in a computer is any readable 
form of that information, so long as it accurately reflects the data, 
this rule is not commonly litigated in the context of electronically 
stored information. 

Still, it is an issue worthy of consideration, particularly when 
appearing before judges who may be less comfortable with the idea of 
evidence being drawn straight from seemingly nebulous digital storage 
media and placed directly into evidence. 

CONCLUSION 

All of these evidentiary issues are, of course, important in the 
context of trial. As the Lorraine decision underscores, however, they 
are equally important when preparing motions for summary judgment. 

Clearing the evidentiary hurdles using any of these methods could 
mean the difference between a successful motion and the uncertainty 
of a trial. In order for a court to consider evidence in a motion for 
summary judgment, the evidence must be submitted in a form that would 
be admissible at trial. Thus courts typically will not consider 
unsworn, unauthenticated documents on a motion for summary judgment; 
documents must be authenticated by and attached to an affidavit that 
meets the requirements of Rule 56(e). 

In view of the increasing focus on electronic discovery, litigation 
counsel are well advised to consider at an early stage not only how 
to obtain electronically stored information, but also how to secure - 
or challenge - its admission into evidence. In the electronic sphere, 
as elsewhere, the fruits of discovery do not inevitably constitute 
competent evidence.
