D. Mass. L.R. 40.1
Assignment of Cases
(a) Civil Cases.
(1) Categories of Cases. All civil cases shall be divided into the following three
categories for purposes of assignment, based upon the numbered “Nature of the
Suit” listed in the civil cover sheet used by the clerk in initiating the civil docket:
I 410, 441, 470, 535, 830, 891, 893, 895, R.23, regardless of nature of suit.
II 110, 130, 140, 160, 190, 196, 230, 240, 290, 320, 362, 370, 371, 380, 430,
440, 442, 443, 445, 446, 448, 710, 720, 740, 790, 820, 840, 850
III 120, 150, 151, 152, 153, 195, 210, 220, 245, 310, 315, 330, 340, 345, 350,
355, 360, 365, 367, 368, 375, 385, 400, 422, 423, 450, 460, 462, 463, 465,
480, 490, 510, 530, 540, 550, 555, 560, 625, 690, 751, 791, 810, 861-865,
890, 896, 899, 950
A copy of the local civil category sheet form referred to is attached as an appendix
to this rule.
(2) Designation of Nature of Suit. The party filing the initial pleading shall complete
a civil cover sheet, Form JS 44, or any successor forms, and file it with the initial
pleading. If the clerk should determine that the designation of Nature of Suit is in
error, the clerk shall correctly classify the suit and notify the party filing the initial
pleading. A designation shall not thereafter be changed except by order of the chief
judge or the district judge to whom the case is assigned.
(3) Assignment. The clerk shall place a case in one of the three categories described in
subsection (a)(1) and, unless otherwise ordered by the court, assign it by lot among
the district judges in active service at their respective duty stations in accordance
with this rule in such manner that each such district judge shall be assigned as nearly
as possible the same number of cases in each category. A senior judge may limit
the category of case and nature of suit assigned to that judge and, within the
categories of cases or suits that senior judge will accept, assignment shall be by lot
in accordance with this rule.
(b) Criminal Cases.
(1) Categories of Cases. All criminal cases shall be divided into the following three
categories:
I - Felony cases expected to require a combined total of 15 days or more for
pretrial hearings and trial before a district judge.
II - All other felony cases.
III - All misdemeanor and petty offense cases where a district judge has been
requested; all cases transferred under Fed. R. Crim. P. 20; cases involving
waivers of indictment; and all matters involving alleged violations of
conditions of release by persons transferred to this district for supervision.
(2) Designation of Category. The attorney for the United States shall identify the
appropriate category on Form JS 45, as modified for the District of Massachusetts,
or any successor form, and submit the form contemporaneously with the document
that initiates the case. If the clerk should determine that the designation of category
is in error, the clerk shall correctly classify the case and notify the attorney for the
United States. The designation shall not thereafter be changed except by order of
the chief judge or the district judge to whom the case is assigned.
(3) Assignment. The clerk shall place a case in one of the three categories described in
subsection (b)(1) and, unless otherwise ordered by the court, assign it by lot among
the district judges in active service at their respective active duty stations within the
divisions of the court in accordance with this rule in such manner that each district
judge shall be assigned as nearly as possible the same number of cases in each
category. A senior judge may limit the category of cases or types of alleged criminal
offenses assigned to that judge and within the categories of cases or offenses that
senior judge will accept, assignment shall be in accordance with this rule.
(c) Designation of Divisions. The District of Massachusetts constitutes one judicial district
comprising three divisions.
(1) Eastern Division. The Eastern Division of the District of Massachusetts comprises
the counties of Barnstable, Bristol, Dukes, Essex, Middlesex, Nantucket, Norfolk,
Plymouth, and Suffolk. Cases assigned to the Eastern Division and all pleadings
and documents therein shall be filed in the clerk's office in Boston.
(2) Central Division. The Central Division of the District of Massachusetts is
Worcester County. Cases assigned to the Central Division and all pleadings and
documents therein shall be filed in the clerk's office in Worcester.
(3) Western Division. The Western Division of the District of Massachusetts comprises
the counties of Berkshire, Franklin, Hampden and Hampshire. Cases shall be
assigned to the Western Division and all pleadings and documents therein shall be
filed in the clerk's office in Springfield.
(d) Assignment of Civil Cases.
(1) Civil cases shall be assigned to the respective divisions if:
(A) All of the parties reside in that division.
(B) All of the parties reside in the District of Massachusetts and the majority of
the plaintiff(s) reside(s) in that division.
(C) The only parties residing in the District of Massachusetts reside in that
division; or
(D) Any of the parties are the United States, the Commonwealth of
Massachusetts, or any governmental agency of either the United States or
the Commonwealth of Massachusetts and a majority of all other parties
resident in the District of Massachusetts reside in that division.
(E) Except as otherwise ordered by the court, cases not governed by subsection
(d)(1) may be filed, subject to reassignment and transfer, in the division
chosen by the plaintiff.
(e) Assignment of Criminal Cases. Criminal cases shall be assigned to that division in
which the most significant criminal conduct related to the alleged violations occurred
within the District of Massachusetts. All documents in each criminal case shall be filed in
the clerk's office administering cases for the division to which that case is assigned.
(f) Transfer between Divisions. Any case may be transferred from one division to another
division on motion of any party for good cause shown or sua sponte for good cause by
the district judge to whom the case is assigned.
(g) Related Civil Cases.
(1) Definition of “Related” Civil Cases. For purposes of this rule, a civil case shall be
deemed related to another civil case only if:
(A) some or all of the parties are the same; and
(B) one or more of the following similarities exist:
i. the cases involve the same or substantially similar issues of fact;
ii. the cases arise out of the same occurrence, transaction or property;
iii. the cases involve insurance coverage for the same property, transaction
or occurrence.
(2) Criminal and Civil Cases. For the purposes of this rule, a civil case shall be deemed
related to a criminal case only if:
(A) the civil case involves forfeiture of property from a transaction or occurrence
that is the subject of a previously filed criminal case, enforcement of a
restitution order or fine imposed in a previously filed criminal case or if it seeks
some other form of civil enforcement relief relating to a previously filed
criminal case.
(3) Common Question of Law Not Sufficient. Civil cases, even when they involve
some or all of the same parties, shall not be deemed related to each other solely on
the ground that they:
(A) involve the same or substantially similar challenges to a law, regulation, or
government policy or practice; or
(B) otherwise involve a common question of law.
(4) Time Limitation. Civil cases shall not be deemed related if more than two years
have lapsed since the closing of the earlier case.
(5) Social Security Cases. Any social security case filed in the district court following
remand shall be deemed related to the initial case notwithstanding subsection (g)(4).
(6) Designation of Relatedness. If the plaintiff (or other party filing the initial pleading)
believes that the case is related to any earlier filed case, whether or not the earlier
case is still open (provided that not more than two years has elapsed since the closing
of the earlier case), that party shall:
(A) notify the clerk by notation on the civil category sheet indicating the title
and number of the earlier filed case; and
(B) file a written certification in the later-filed case specifically stating the basis
for designating the two cases as related.
(C) Unless good cause is shown, designation of relatedness by plaintiff (or other
party filing the initial pleading) shall be made at the time of the filing of the
initial pleading.
(7) Objection to Designation of Relatedness or Lack of Designation of Relatedness.
(A) If the defendant (or other responding party) believes that a case that has been
designated as related should not have been so designated, that party shall file
a motion in the later filed case to return the case to the clerk for reassignment.
(B) If the defendant (or other responding party) believes that a case that has not
been designated as related should have been so designated, that party shall
file a motion in the later filed case for the judge’s consideration of transfer or
reassignment of the case pursuant to Section i of this Rule.
(C) Unless good cause is shown, objection to designation of relatedness or lack
of designation of relatedness shall be made within 30 days of a responsive
pleading being filed.
(8) Assignment by Clerk. The clerk shall assign related cases to the same district judge
without regard to the number of other cases in that category previously assigned to that
judge. Related cases shall be counted as cases assigned, except as the chief judge may otherwise
direct.
(9) Correction of Designation as “Related.” The assignment of cases as related by the
clerk shall be subject to correction only by the district judge to whom they have been
assigned, who shall return cases erroneously assigned on that basis to the clerk for
reassignment.
(10) Correction of Designation as “Not Related.” The treatment of a case as not related
to another case shall be subject to correction only by the joint decision of the district
judge to whom it has been assigned and the district judge to whom it should be
assigned, if related to an earlier filed case. The judges may then transfer the case
pursuant to Section i of this Rule and shall notify the clerk of the transfer.
(h) Related Criminal Cases.
(1) Definition of “Related” Criminal Cases. For purposes of this rule, a criminal case
shall be deemed related to another criminal case only if:
(A) the case arises out of the same, or substantially similar, charged scheme(s),
transaction(s) and/or event(s) or a series of same, regardless of whether the matter
is charged as a conspiracy;
or
(B) one or more cases, by sharing common events or defendants, would entail
substantial duplication of effort in the pretrial, trial and/or sentencing phases if
heard by different judges.
That an individual defendant is charged in more than one case before different judges pending at
the same time (if those cases are not otherwise related as defined above) does not make those cases
related. However, nothing in this subsection shall bar transfer of a revocation matter involving new
criminal conduct to the judge who has drawn any new indictment for that criminal conduct.
Moreover, nothing in this subsection shall bar the transfer of criminal cases as allowed under
Section (j)(2) of this Rule.
(2) Criminal and Civil Cases. For the purposes of this rule, a criminal case shall be deemed
related to a civil case only under the circumstance explained in Section (g)(2) of this
Rule.
(3) Common Questions of Law Not Sufficient. Criminal cases, even when they involve some
or all of the same defendants, shall not be deemed related to each other solely on the
ground that they:
(A) involve the same charge(s);
(B) challenge the legality of the charge or government policy or practice; or
(C) otherwise involve a common question of law.
(4) Time Limitation. Criminal cases shall not be deemed related if more than two years have
lapsed since the closing of the earlier case and commencement of the new case.
(5) Designation of Relatedness. If the government believes that the case is related to any
earlier filed case (regardless of whether the earlier case was initiated by indictment or
information) and whether or not the earlier case is still open (provided that not more
than two years has elapsed since the closing of the earlier case), the government shall:
(A) notify the clerk by notation on the criminal category sheet indicating the title and
number of the earlier filed case; and
(B) file a written certification in the later-filed case specifically stating the basis for
designating the two cases as related.
(C) Unless good cause is shown, designation of relatedness by the government shall be
made at the time of the filing of the initial charging document (whether that is by
indictment or information). One example of “good cause” would be the prior
authorized sealing of the indictment or information.
(6) Objection to Designation of Relatedness or Lack of Designation of Relatedness.
(A) If a defendant believes that a case that has been designated as related should not
have been so designated, that party shall file a motion in the later filed case to return
the case to the clerk for reassignment.
(B) If a defendant believes that a case that has not been designated as related should
have been so designated, that party shall file a motion in the later filed case for the
judge’s consideration of transfer or reassignment of the case pursuant to Section j
of this Rule.
(C) Unless good cause is shown, objection to designation of relatedness or lack of
designation of relatedness shall be made within 30 days of arraignment.
(7) Assignment by Clerk. The clerk shall assign related cases to the same district judge
without regard to the number of other cases in that category previously assigned to that
judge. Related cases shall be counted as cases assigned, except as the chief judge may
otherwise direct.
(8) Correction of Designation as “Related.” The assignment of cases as related by the clerk
shall be subject to correction only by the district judge to whom they have been assigned,
who shall return cases erroneously assigned based on relatedness to the clerk for
reassignment.
(9) Correction of Designation as “Not Related.” The treatment of a case as not related to
another case shall be subject to correction only by the joint decision of the district judge
to whom it has been assigned and the district judge to whom it would be assigned, if
related to an earlier filed case. If a joint decision between the district judges cannot be
reached, then the chief judge shall decide if correction is necessary. The judge(s) may
then transfer the case and shall notify the clerk of the transfer.
(i) Proceedings after Assignment. Unless otherwise ordered by the court, all proceedings in
a case after its assignment shall be conducted before the district judge to whom it has been assigned,
except as otherwise provided in these rules. This subsection does not preclude reassignment of
cases by the court or the clerk, at the direction of the court, without prior notice to the parties.
(j) Reassignment and Transfer of Cases.
(1) Generally. In the interest of justice or to further the efficient performance of the
business of the court, a district judge may return a case to the clerk for
reassignment, whether or not the case is related to any other case, with the
approval of the chief judge, or, with respect to civil cases only and whether or
not the case is related to any other case, may transfer the case to another district
judge, if the other judge consents to the transfer.
(2) Transfers of Criminal Cases. A district judge may transfer a criminal case to
another district judge, with the consent of (1) the other judge, (2) the chief judge,
and (3) the parties in the transferred case, in order to permit a defendant charged
in multiple criminal cases to plead guilty, to stand trial, to be sentenced, or
otherwise to address in a single proceeding multiple criminal cases in which that
defendant has been charged.
(k) Motion for Consolidation of Cases. A motion for consolidation of two or more cases
shall be made in the case first filed in this court.
(l) Proceedings after Appeal.
(1) When an appellate court remands a case to this court for a new trial, the case shall
be reassigned to a district judge other than the judge before whom the first trial was
held.
(2) In all other cases in which the mandate of the appellate court requires further
proceedings in this court, such proceedings shall not be conducted before the district
judge before whom the prior proceedings were conducted unless the terms of the
remand require that further proceedings be conducted before the original judge or
unless the judge determines that there will result a substantial saving in the time of
the whole court and that there is no reason why, in the interest of justice, further
proceedings should be conducted before another judge. If the judge before whom
the prior proceedings were conducted does not retain the case for further
proceedings, that judge shall return it to the clerk for reassignment.
(m) Drawing of Civil Cases to Magistrate Judges. The court may adopt policies and
procedures permitting the assignment of certain civil cases to magistrate judges rather
than to district judges in accordance with this rule. Any such policies and procedures shall
include a requirement that the parties consent to the assignment, consistent with the
requirements of 28 U.S.C. § 636(c) and other federal law.
