Del. Ch. Ct. R. 26
General Provisions Governing Discovery
(a) Discovery Methods. Parties may obtain discovery
by 1 or more of the following methods: Depositions upon
oral examination or written questions; written
interrogatories; production of documents, electronically
stored information, or tangible things or permission to
enter upon land or other property, for inspection and other
purposes; physical and mental examinations; and requests
for admission. Unless the Court orders otherwise under
paragraph (c) of this rule, the frequency of use of these
methods is not limited.
(b) Discovery Scope and Limits. Unless otherwise
limited by order of the Court in accordance with these
Rules, the scope of discovery is as follows:
(1) In General. Parties may obtain discovery
regarding any non-privileged matter that is relevant to
any party’s claim or defense and proportional to the
needs of the case, including the existence, description,
nature, custody, condition and location of any
documents, electronically stored information, or
tangible things and the identity and location of persons
having knowledge of any discoverable matter. It is not
ground for objection that the information sought will be
inadmissible at the trial.
The frequency or extent of use of the discovery
methods set forth in paragraph (a) shall be limited
by the Court if it determines that: (i) the discovery
sought is unreasonably cumulative or duplicative, or
is obtainable from some other source that is more
convenient, less burdensome, or less expensive; (ii)
the party seeking discovery has had ample
opportunity by discovery in the action to obtain the
information sought; or (iii) the discovery sought is
not proportional to the needs of the case, considering
the importance of the issues at stake in the action,
the amount in controversy, the parties’ relative
access to relevant information, the parties’
resources, the importance of the discovery in
resolving the issues, and whether the burden or
expense of the proposed discovery outweighs its
likely benefit. The Court may act upon its own
initiative after reasonable notice or pursuant to a
motion under paragraph (c).
(2) Insurance Agreements. A party may obtain
discovery of the existence and contents of any insurance
agreement under which any person carrying on an
insurance business may be liable to satisfy part or all of
a judgment which may be entered in the action or to
indemnify or reimburse for payments made to satisfy
the judgment. Information concerning the insurance
agreement is not by reason of disclosure admissible in
evidence at trial. For purposes of this subparagraph, an
application for insurance shall not be treated as part of
an insurance agreement.
(3) Trial Preparation: Materials. Subject to the
provisions of paragraph (b) (4) of this rule, a party may
obtain discovery of documents, electronically stored
information, and tangible things otherwise discoverable
under paragraph (b)(1) of this rule and prepared in
anticipation of litigation or for trial by or for another
party or by or for that other party’s representative
(including the other party’s attorney, consultant,
surety, indemnitor, insurer, or agent) only upon a
showing that the party seeking discovery has
substantial need of the materials in the preparation of
the party’s case and that the party is unable without
undue hardship to obtain the substantial equivalent of
the materials by other means. In ordering discovery of
such materials when the required showing has been
made, the Court shall protect against disclosure of the
mental impressions, conclusions, opinions, or legal
theories of an attorney or other representative of a
party concerning the litigation.
A party may obtain without the required showing a
statement concerning the action or its subject
matter previously made by that party. Upon request,
a person not a party may obtain without the
required showing a statement concerning the action
or its subject matter previously made by that person.
If the request is refused, the person may move for a
Court order. The provisions of Rule 37(a)(4) apply to
the award of expenses incurred in relation to the
motion. For purposes of this paragraph, a statement
previously made is (A) a written statement signed or
otherwise adopted or approved by the person
making it, or (B) a stenographic, mechanical,
electrical, or other recording, or a transcription
thereof, which is a substantially verbatim recital of
an oral statement by the person making it and
contemporaneously recorded.
(4) Trial Preparation: Experts. Discovery of facts
known and opinions held by experts, otherwise
discoverable under the provisions of paragraph (b)(1) of
this rule and acquired or developed in anticipation of
litigation or for trial, may be obtained only as follows:
(A)(i) A party may through interrogatories require
any other party to identify each person whom the
other party expects to call as an expert witness at
trial, to state the subject matter on which the expert
is expected to testify, and to state the substance of
the facts and opinions to which the expert is
expected to testify and a summary of the grounds for
each opinion. (ii) Upon motion, the Court may order
further discovery by other means, subject to such
restrictions as to scope and such provisions,
pursuant to paragraph (b)(4)(C) of this rule,
concerning fees and expenses as the Court may deem
appropriate.
(B) A party may discover facts known or opinions
held by an expert who has been retained or specially
employed by another party in anticipation of
litigation or preparation for trial and who is not
expected to be called as a witness at trial, only as
provided in Rule 35(b) or upon a showing of
exceptional circumstances under which it is
impracticable for the party seeking discovery to
obtain facts or opinions on the same subject by other
means.
(C) Unless manifest injustice would result, (i) the
Court shall require that the party seeking discovery
pay the expert a reasonable fee for time spent in
responding to discovery under paragraphs
(b)(4)(A)(ii) and (b)(4)(B) of this rule and (ii) with
respect to discovery obtained under paragraphs
(b)(4)(A)(ii) of this rule the Court may require, and
with respect to discovery obtained under paragraph
(b)(4)(B) of this rule the Court shall require, the
party seeking discovery to pay the other party a fair
portion of the fees and expenses reasonably incurred
by the latter party in obtaining facts and opinions
from the expert.
(c) Protective Orders. Upon motion by a party or by
the person from whom discovery is sought, and for good
cause shown, the Court or alternatively, on matters
relating to a deposition taken outside the State of
Delaware, a court in the state where the deposition is to be
taken may make any order which justice requires to protect
a party or person from annoyance, embarrassment,
oppression, or undue burden or expense, including 1 or
more of the following: (1) That the discovery not be had; (2)
that the discovery may be had only on specified terms and
conditions, including a designation of the time or place or
the allocation of expenses; (3) that the discovery may be
had only by a method of discovery other than that selected
by the party seeking discovery; (4) that certain matters not
be inquired into, or that the scope of the discovery be
limited to certain matters; (5) that discovery be conducted
with no one present except persons designated by the
Court; (6) that a deposition after being sealed be opened
only by order of the Court; (7) that a trade secret or other
confidential research, development, or commercial
information not be disclosed or be disclosed only in a
designated way; (8) that the parties simultaneously file
specified documents or information enclosed in sealed
envelopes to be opened as directed by the Court. A party
has standing to move for a protective order with respect to
discovery directed at a non-party on the basis of annoyance,
embarrassment, oppression, or undue burden or expense
that the moving party will bear. A non-party from another
state from whom discovery is sought always may move for
a protective order from the court in the state where
discovery is sought or, alternatively, from this Court
provided the non-party agrees to be bound by the decision
of this Court as to the discovery in question.
If the motion for a protective order is denied in whole or
in part, the Court may, on such terms and conditions as
are just, order that any party or person provide or
permit discovery. The provisions of Rule 37(a)(4) apply
to the award of expenses incurred in relation to the
motion.
(d) Sequence and Timing of Discovery. Unless the
Court upon motion, for the convenience of parties and
witnesses and in the interests of justice, orders otherwise,
methods of discovery may be used in any sequence and the
fact that a party is conducting discovery, whether by
deposition or otherwise, shall not operate to delay any
other party’s discovery.
(e) Supplementation of Responses. A party who has
responded to a request for discovery with a response that
was complete when made is under no duty to supplement
the response to include information thereafter acquired,
except as follows:
(1) A party is under a duty seasonably to supplement
the response with respect to any question directly
addressed to (A) the identity and location of persons
having knowledge of discoverable matters, and (B) the
identity of each person expected to be called as an
expert witness at trial, the subject matter on which the
person is expected to testify, and the substance of the
person’s testimony.
(2) A party is under a duty seasonably to amend a
prior response if the party obtains information upon the
basis of which (A) the party knows that the response
was incorrect when made, or (B) the party knows that
the response though correct when made is no longer
true and the circumstances are such that a failure to
amend the response is in substance a knowing
concealment.
(3) A duty to supplement responses may be imposed
by order of the Court, agreement of the parties, or at
any time prior to trial through new requests for
supplementation of prior responses.
