United States Tax Court
Rules

TITLE X
GENERAL PROVISIONS GOVERNING DISCOVERY, DEPOSITIONS, AND REQUESTS FOR ADMISSIONS
Rule 100. Applicability
The Rules in this Title apply according to their terms to
written interrogatories (Rule 71), production of documents or
things (Rule 72), examination by transferees (Rule 73),
depositions (Rules 74, 75, 76, 81, 82, 83, and 84), and requests
for admission (Rule 90). Such procedures may be used in
anticipation of the stipulation of facts required by Rule 91, but
the existence of such procedures or their use does not excuse
failure to comply with the requirements of that Rule. See Rule
91(a)(2).
Rule 101. Sequence, Timing, and Frequency
Unless the Court orders otherwise for the convenience of the
parties and witnesses and in the interests of justice, and
subject to the provisions of the Rules herein which apply more
specifically, the procedures set forth in Rule 100 may be used in
any sequence, and the fact that a party is engaged in any such
method or procedure shall not operate to delay the use of any
such method or procedure by any other party. However, none of
these methods or procedures shall be used in a manner or at a
time which shall delay or impede the progress of the case toward
trial status or the trial of the case on the date for which it is
noticed, unless in the interests of justice the Court shall order
otherwise. Unless the Court orders otherwise under Rule 103, the
frequency of use of these methods or procedures is not limited.
Rule 102. Supplementation of Responses
A party who has responded to a request for discovery (under
Rules 71, 72, 73, 74, 75, or 76) or to a request for admission
(under Rule 90) in a manner which 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 matter 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
such person is expected to testify, and the substance of such
person's testimony. In respect of the requirement to furnish
reports of expert witnesses, see Rule 143(f)(1).
(2) A party is under a duty seasonably to amend a prior
response if the party obtains information upon the basis of which
the party knows that (A) the response was incorrect when made, or
(B) 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.
Rule 103. Protective Orders
(a) Authorized orders. Upon motion by a party or any other
affected person, and for good cause shown, the Court may make any
order which justice requires to protect a party or other person
from annoyance, embarrassment, oppression, or undue burden or
expense, including but not limited to one or more of the
following:
(1) That the particular method or procedure not be used.
(2) That the method or procedure be used only on specified
terms and conditions, including a designation of the time or
place.
(3) That a method or procedure be used other than the one
selected by the party.
(4) That certain matters not be inquired into, or that the
method be limited to certain matters or to any other extent.
(5) That the method or procedure be conducted with no one
present except persons designated by the Court.
(6) That a deposition or other written materials, after being
sealed, be opened only by order of the Court.
(7) That a trade secret or other 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.
(9) That expense involved in a method or procedure be borne in
a particular manner or by specified person or persons.
(10) That documents or records be impounded by the Court to
insure their availability for purpose of review by the parties
prior to trial and use at the trial.
If a discovery request has been made, then the movant shall
attach as an exhibit to a motion for a protective order under
this Rule a copy of any discovery request in respect of which the
motion is filed.
(b) Denials. If a motion for a protective order is denied in
whole or in part, then the Court may, on such terms or conditions
it deems just, order any party or person to comply or to respond
in accordance with the procedure involved.
Rule 104. Enforcement Action and Sanctions
(a) Failure to attend deposition or to answer interrogatories
or respond to request for inspection or production. If a party,
or an officer, director, or managing agent of a party, or a
person designated in accordance with Rule 74(b), 75(c), or 81(c)
to testify on behalf of a party fails (1) to appear before the
officer who is to take such person's deposition pursuant to Rule
74, 75, 76, 81, 82, 83, or 84, or (2) to serve answers or
objections to interrogatories submitted under Rule 71, after
proper service thereof, or (3) to serve a written response to a
request for production or inspection submitted under Rule 72 or
73 after proper service of the request, then the Court on motion
may make such orders in regard to the failure as are just, and
among others it may take any action authorized under paragraph
(b) or (c) of this Rule. If any person, after being served with a
subpoena or having waived such service, willfully fails to appear
before the officer who is to take such person's deposition or
refuses to be sworn, or if any person willfully fails to obey an
order requiring such person to answer designated interrogatories
or questions, then such failure may be considered contempt of
court. The failure to act described in this paragraph (a) may not
be excused on the ground that the deposition sought, or the
interrogatory submitted, or the production or inspection sought,
is objectionable, unless the party failing to act has theretofore
raised the objection, or has applied for a protective order under
Rule 103, with respect thereto at the proper time and in the
proper manner, and the Court has either sustained or granted or
not yet ruled on the objection or the application for the order.
(b) Failure to answer. If a person fails to answer a question
or interrogatory propounded or submitted in accordance with Rule
71, 74, 75, 76, 81, 82, 83, or 84, or fails to respond to a
request to produce or inspect or fails to produce or permit the
inspection in accordance with Rule 72 or 73, or fails to make a
designation in accordance with Rule 74(b), 75(e), or 81(c), the
aggrieved party may, within the time for completion of discovery
under Rule 70(a)(2), move the Court for an order compelling an
answer, response, or compliance with the request, as the case may
be. When taking a deposition on oral examination, the examination
may be completed on other matters or the examination adjourned,
as the proponent of the question may prefer, before applying for
such order.
(c) Sanctions. If a party or an officer, director, or managing
agent of a party or a person designated in accordance with Rule
74(b), 75(c), or 81(c) fails to obey an order made by the Court
with respect to the provisions of Rule 71, 72, 73, 74, 75, 76,
81, 82, 83, 84, or 90, then the Court may make such orders as to
the failure as are just, and among others the following:
(1) An order that the matter regarding which the order was
made or any other designated facts shall be taken to be
established for the purposes of the case in accordance with the
claim of the party obtaining the order.
(2) An order refusing to allow the disobedient party to
support or oppose designated claims or defenses, or prohibiting
such party from introducing designated matters in evidence.
(3) An order striking out pleadings or parts thereof, or
staying further proceedings until the order is obeyed, or
dismissing the case or any part thereof, or rendering a judgment
by default against the disobedient party.
(4) In lieu of the foregoing orders or in addition thereto,
the Court may treat as a contempt of the Court the failure to
obey any such order, and the Court may also require the party
failing to obey the order or counsel advising such party, or
both, to pay the reasonable expenses, including counsel's fees,
caused by the failure, unless the Court finds that the failure
was substantially justified or that other circumstances make an
award of expenses unjust.
(d) Evasive or incomplete answer or response. For purposes of
this Rule and Rules 71, 72, 73, 74, 75, 76, 81, 82, 83, 84, and
90, an evasive or incomplete answer or response is to be treated
as a failure to answer or respond.
Rule 105--109. [Reserved]
