UNITED STATES DISTRICT COURT                            
                   DISTRICT OF SOUTH DAKOTA                              
                      NORTHERN DIVISION                                  
LUCAS MACK, INDIVIDUALLY AND AS          1:24-CV-01013-CCT               
PERSONAL REPRESENTATIVE OF THE                                           
ESTATE OF HEIDI MACK;                                                    
               Plaintiff,          ORDER GRANTING IN PART AND            
                                    DENYING IN PART PLAINTIFF’S          
                                       MOTION FOR PARTIAL                
    vs.                                SUMMARY JUDGMENT                  
UNITED STATES OF AMERICA,                                                
               Defendant.                                                
    Plaintiff, Lucas Mack (Mack), in his individual capacity, as personal 
representative of the Estate of Heidi Mack, and as guardian ad litem for A.M., 
brings this action against Defendant, United States of America, pursuant to the 
Federal Tort Claims Act (FTCA). Docket 1. Mack alleges that on August 19, 
2023, Heidi Mack (Heidi) and A.M. were traveling on 458th Avenue (“Whipple 
Road”) in Roberts County, South Dakota, when a vehicle operated by Ignacio 
Galarza, an employee of United State Postal Service (USPS), negligently collided 
with the John Deere Gator being operated by Heidi, causing the death of Heidi 
and injuring A.M. Id. ¶¶ 7, 10-11, 18. Mack contends that at the time of the 

incident, Galarza was acting within the course and scope of his employment 
with USPS. Id. ¶ 10.                                                      
    Mack now moves for partial summary judgment in his favor, asserting  
that (1) Galarza was negligent as a matter of law and (2) he was acting within 
the course and scope of his employment with the USPS at the time of the   
collision. Docket 20 at 1-2. Mack also requests that the Court “take judicial 
notice of the fact that Ignacio Galarza pleaded guilty to and was convicted of 

careless driving under SDCL 32-24-8 for the manner in which he operated his 
vehicle at the relevant time in question[.]” Id. at 1-2. The government has filed a 
response in opposition. Docket 24. Mack has submitted a reply. Docket 27. 
                         BACKGROUND                                      
    Unless otherwise noted, the following facts are uncontested.1        
    On August 19, 2023, Heidi and her daughter A.M. were traveling       
northbound on Whipple Road, “which is a rural two-lane asphalt road with a 
posted speed limit of 55 mph.” Docket 22 ¶¶ 1-3; Docket 25 ¶¶ 1-3. Traveling 

behind Heidi was USPS clerk Galarza, who was traveling from the post office in 
Summit, South Dakota (the “Summit Office”) to the post office in Peever, South 
Dakota (the “Peever Office”). Docket 22 ¶¶ 1-2, 5; Docket 25 ¶¶ 1-2. At some 
point, when Heidi attempted to make a left turn, Galarza collided with Heidi. 
Docket 22 ¶¶ 5-6; Docket 25 ¶ 6.                                          



1 The government asserts that it is unable to fully respond to certain of Mack’s 
asserted undisputed material facts because discovery has not yet occurred, and the 
case remains in its early stages. Docket 24. As a result, the government states that it 
lacks sufficient information to admit or deny some of Mack’s factual assertions. Id.; 
Docket 25. While Local Rule 56.1(B) requires a party opposing a summary judgment to 
specifically identify material facts in dispute and support such disputes with citations 
to the record, the Court recognizes that the current procedural posture limits the 
development of a complete factual record. Accordingly, the background section reflects 
those facts that are admitted by the government, as well as certain factual allegations 
made by Mack that are not yet admitted or denied.                         
    After the incident, South Dakota Highway Patrol Trooper Juan Flores  
investigated the accident. Docket 22 ¶ 11. During the course of the       
investigation, it was revealed that Galarza was traveling 65 miles per hour at 

the time of the collision. Id. ¶ 15. As a result of Trooper Flores’s investigation, 
Galarza was cited for, among other things, careless driving. Id. ¶ 17; Docket 25 
¶ 17. Galarza ultimately pled guilty to and was convicted of careless driving 
under SDCL § 32-24-8. Docket 22 ¶ 18; Docket 25 ¶ 18.                     
    On June 12, 2024, “Mack brought this Federal Tort Claims Act         
proceeding against the [government] seeking damages for the wrongful death of 
Heidi, injuries caused to A.M., and property damage.” Docket 22 ¶ 19; Docket 
25 ¶ 19. “In its Answer, the [government] admitted Galarza was acting in the 

course and scope of his employment with the USPS during all times relevant to 
the Complaint but denied Galarza was negligent.” Docket 22 ¶ 20; Docket 25   
¶ 20.                                                                     
                          DISCUSSION                                     
I.  Judicial Notice                                                      
    As a preliminary matter, the Court addresses Mack’s request for the  
Court to “take judicial notice of the fact that Galarza pleaded guilty to and was 
convicted of careless driving under SDCL 32-24-8[.]” Docket 21 at 2. The  

government does not dispute that the “citation and South Dakota State Court 
Judgment of Conviction and Sentence of the Court” exists. Docket 24 at 3. 
Therefore, it does not object to the Court taking judicial notice of the existence 
of these documents; however, it contends that taking “judicial notice of any 
underlying facts of the” conviction “would not be appropriate in applying them 
to the present case.” Id. (emphasis added).                               
    Under Federal Rule of Evidence 201, a court may take judicial notice of 

information “not subject to reasonable dispute because it (1) is generally known 
within the trial court’s territorial jurisdiction; or (2) can be accurately and 
readily determined from sources whose accuracy cannot reasonably be       
questioned.” Fed. R. Evid. 201(b). “The court may take judicial notice at any 
stage of the proceeding.” Fed. R. Evid. 201(d). Courts may take judicial notice 
of judicial opinions and public records. Stutzka v. McCarville,
420 F.3d 757
, 
760 n.2 (8th Cir. 2005). However, “[j]udicial notice of another court’s opinion 
takes notice of existence of the opinion, which is not subject to reasonable 

dispute over its authenticity, but not of the facts summarized in the opinion.” 
McIvor v. Credit Control Servs., Inc.,
773 F.3d 909, 914
(8th Cir. 2014) (cleaned 
up). Nonetheless, under Rule 201, a court may take judicial notice of an  
adjudicative fact as long as such a fact “is not subject to reasonable dispute[.]” 
Fed. R. Evid. 201(b). Adjudicative facts are “facts that normally go to the jury in 
a jury case. They relate to the parties, their activities, their properties, their 
businesses.” Fed. R. Evid. 201(a) advisory committee notes (citation omitted); 
see United States v. Gould,
536 F.2d 216, 219
(8th Cir. 1976) (stating that 

adjudicative facts concern “who did what, where, when, how and with what  
motive or intent” (citation omitted)).                                    
    Here, the Court finds that judicial notice is proper as to certain facts not 
reasonably subject to dispute. Specifically, the Court takes judicial notice of: 
(1) the fact that Galarza pled guilty to and was convicted of careless driving 
under SDCL § 32-24-8; and (2) the judgment of conviction and sentence     
entered by the state court. See Stutzka,
420 F.3d at 761
n.2 (taking judicial 

notice of the default judgment in a related case in its consideration); BMO 
Harris Bank, N.A. v. MCM, Inc., Civil No. 17-335 (DWF/KMM),
2017 WL       
3443238
, at *4 (D. Minn. Aug. 8, 2017) (taking “judicial notice of the aspects 
that are not subject to reasonable dispute” in the contempt order). These facts 
have been expressly admitted to by the government in its response to Mack’s 
statement of undisputed material facts and are therefore not subject to   
reasonable dispute. Docket 25 ¶ 17; Docket 24 at 3; see Fed. R. Evid. 201(b).   
II.  Summary Judgment                                                    

    “[S]ummary judgment is an extreme remedy, and one which is not to be 
granted unless the movant has established his right to a judgment with such 
clarity as to leave no room for controversy and that the other party is not 
entitled to recover under any discernible circumstances.” Robert Johnson Grain 
Co. v. Chem. Interchange Co.,
541 F.2d 207, 209
(8th Cir. 1976). The purpose of 
summary judgment is not “to cut litigants off from their right of trial by jury if 
they really have issues to try.” Poller v. Columbia Broad. Sys., Inc.,
368 U.S. 
464, 467
(1962) (quoting Sartor v. Ark. Nat’l Gas Corp.,
321 U.S. 620, 627
(1944)). Rather, it is designed to “avoid[ ] useless, expensive and time- 
consuming trials where there is actually no genuine, factual issue remaining to 
be tried.” Anderson v. Viking Pump Div., Houdaille Indus.,
545 F.2d 1127, 1129
(8th Cir. 1976).                                                          
    Under Federal Rule of Civil Procedure 56(a), a movant is entitled to 
summary judgment if the movant “shows that there is no genuine dispute as to 
any material fact and the movant is entitled to judgment as a matter of law.” 

Fed. R. Civ. P. 56(a). Once the moving party meets its burden, the nonmoving 
party “may not rest upon mere allegation or denials of his pleading, but must 
set forth specific facts showing that there is a genuine issue for trial.” Anderson 
v. Liberty Lobby, Inc.,
477 U.S. 242, 256
(1986). “Summary judgment is    
appropriate when the evidence, viewed in the light most favorable to the non-
moving party, demonstrates that there is no genuine issue of material fact, and 
that the moving party is entitled to judgment as a matter of law.” Clark v. 
Kellogg Co.,
205 F.3d 1079
, 1082 (8th Cir. 2000) (citation omitted).      

    Only disputes over facts that might affect the outcome of the case under 
the governing substantive law will properly preclude summary judgment.    
Liberty Lobby,
477 U.S. at 248
. “[T]he mere existence of some alleged factual 
dispute between the parties will not defeat an otherwise properly supported 
motion for summary judgment; the requirement is that there be no genuine  
issue of material fact.”
Id. at 247-48
. A disputed issue is “genuine” when the 
evidence produced “is such that a reasonable jury could return a verdict for the 
nonmoving party.”
Id. at 248
. A fact is considered “material” if it “might affect 

the outcome of the suit under the governing law[.]”
Id.
“As to materiality, the 
substantive law will identify which facts are material . . . Factual disputes that 
are irrelevant or unnecessary will not be counted.”
Id.
“In considering a motion for summary judgment the court does not weigh 
the evidence, make credibility determinations, or attempt to discern the truth 
of any factual issue.” Great Plains Real Est. Dev., L.L.C. v. Union Cent. Life Ins. 

Co.,
536 F.3d 939, 943-44
(8th Cir. 2008) (citation omitted). Rather, the court 
only determines whether there are any disputed issues concerning the      
existence of material facts and, if so, whether those disputes are genuine. See 
Liberty Lobby,
477 U.S. at 251-52
; see also Wilson v. Myers,
823 F.2d 253
, 256 
(8th Cir. 1987) (“Summary judgment is not designed to weed out dubious    
claims, but to eliminate those claims with no basis in material fact.”).  
    Here, Mack seeks partial summary judgment on two issues: (1) whether 
Galarza was negligent in the operation of his vehicle at the time of the incident, 

and (2) whether Galarza was acting within the course and scope of his     
employment with the USPS at the time in question. Docket 20. In its opposition 
response, the government does not substantively dispute either issue at this 
stage but instead urges the Court to defer ruling on Mack’s motion until the 
parties have had the opportunity to engage in adequate discovery. Docket 24 at 
3-5. The government asserts that it has not yet had access to critical discovery 
necessary to ascertain facts essential to the development of its defenses and, as 
a result, is presently unable to properly oppose Mack’s motion at this time. Id. 

at 4. In his reply, Mack asserts that the government has been on notice and 
had the opportunity to investigate his claim before the commencement of this 
action. Docket 27 at 5 n.3 (noting that the government acknowledged it    
received his claim on November 9, 2023). Mack further asserts that “[s]ince 
filing its responsive materials, the [government] has deposed A.M., Jean  
Backman, and June Backman.” Id. at 6 n.4.                                 
      a. Whether partial summary judgment on the issue of                
         negligence is appropriate.                                      

    Federal Rule of Civil Procedure 56(d) (formerly Rule 56(f))2 permits a 
party opposing summary judgment to request the court defer decision on a  
summary judgment motion until adequate discovery is completed. The Eighth 
Circuit has explained that:                                               
         To  obtain  a  Rule  56(f)  continuance,  the  party  opposing  
         summary  judgment  must  file  an  affidavit  “affirmatively    
         demonstrating  .  .  .  how  postponement  of  a  ruling  on  the 
         motion will enable him, by discovery or other means, to rebut   
         the movant’s showing of the absence of a genuine issue of       
         fact.”                                                          

Ray v. Am. Airlines, Inc.,
609 F.3d 917, 923
(8th Cir 2010) (quoting Humphreys 
v. Roche Biomedical Lab., Inc.,
990 F.2d 1078, 1081
(8th Cir. 1993)); see 
Ballard v. Heineman,
548 F.3d 1132, 1137
(8th Cir. 2008) (“Unless a party files 
an affidavit under Federal Rule of Civil Procedure 56(f) showing what facts 
further discovery may uncover, ‘a district court generally does not abuse its 
discretion in granting summary judgment on the basis of the record before it.’” 
(quoting Nolan v. Thompson,
521 F.3d 983, 986
(8th Cir. 2008)).           

2 Rule 56(f) was “recodified without substantial change as Rule 56(d)” in December 
2010. Chambers v. Travelers Cos., Inc.,
668 F.3d 559, 568
(8th Cir. 2012) (internal 
quotation marks omitted). The textual changes were for stylistic purposes, and “the 
case law developed under the Rule 56(f) version remains controlling precedent.” 
Fraserside IP L.L.C. v. Youngtek Sols. Ltd., No. C11-3005-MWB,
2012 WL 2906462
, at 
*2 n.1 (N.D. Iowa July 16, 2012).                                         
    Accordingly, it is not enough to assert in general terms that additional 
facts may be uncovered. Rather, the party invoking Rule 56(d) must show: “(1) 
that they have set forth in affidavit form the specific facts that they hope to 

elicit from further discovery, (2) that the facts sought exist, and (3) that these 
sought-after facts are ‘essential’ to resist the summary judgment motion.” 
Toben v. Bridgestone Retail Operations, LLC,
751 F.3d 888, 895
(8th Cir. 2014) 
(citation omitted); see Simmons Oil Corp. v. Tesoro Petrol. Corp.,
86 F.3d 1138, 
1144
(Fed. Cir. 1996) (explaining that a party invoking Rule 56(f) relief “must 
demonstrate specifically ‘how postponement of a ruling on the motion will 
enable it, by discovery or other means, to rebut the movant’s showing of the 
absence of a genuine issue of fact’” (quoting Willmar Poultry Co. v. Morton-

Norwich Prods., Inc.,
520 F.2d 289, 297
(8th Cir. 1975), cert. denied,
424 U.S. 
915
(1976)).                                                              
    Here, the government has filed the declaration of Yvette K. LaFrentz 
pursuant to Federal Rule of Civil Procedure 56(d) summarizing the timeline of 
discovery in the case as of December 10, 2024, and describing the witnesses it 
planned to depose that may have information about liability. Docket 26. The 
declaration also describes that hundreds of documents were provided in Mack’s 
initial disclosures which included investigation records and a video. Id. ¶ 4. 

The government contends that Mack served his initial disclosures on October 
31, 2024, just nineteen days prior to filing his motion for partial summary 
judgment. Id. ¶¶ 2, 4. The government asserts that it has not yet had the 
opportunity to depose any witnesses, including the two individuals who    
allegedly observed the accident. Docket 24 at 4.3 The government thus asserts 
that it “is unable to discover the facts necessary to support any defenses they 
may have” and that they should be “afforded the opportunity to discover any 

facts that may assist in its defense[.]” Id. at 4-5. In response, Mack argues that 
the government’s Rule 56(d) motion is deficient because it fails to specifically 
identify the facts it seeks to uncover through further discovery. Docket 27 at 6. 
He contends that the government makes only vague references to individuals it 
intends to depose and “fails to explain what specific facts it hopes to uncover 
through said depositions[.]” Id.                                          
    The Court finds that the government has identified with sufficient   
specificity which witnesses it wishes to depose and has identified that this 

discovery is related to the issue of liability. “Under the Federal Rules of Civil 
Procedure, the parties must be afforded adequate time for general discovery 
before being required to respond to a motion for summary judgment.” Metro. 
Life Ins. Co. v. Bancorp Servs., L.L.C.,
527 F.3d 1330
, 1336–37 (Fed. Cir. 2008) 
(citing Iverson v. Johnson Gas Appliance Co.,
172 F.3d 524, 530
(8th Cir. 1999) 
(“[S]ummary judgment is proper ‘only after the nonmovant has had adequate 
time for discovery.’” (additional citations omitted)). “When, as here, there has 
been no adequate initial opportunity for discovery, a strict showing of necessity 

and diligence that is otherwise required for a Rule 56(f) request for additional 
discovery does not apply.” Id. at 1337 (internal citation omitted). Given the 

3 Mack indicated in his reply brief that the government did take the depositions of 
A.M., Jean Backman and June Backman, albeit after it responded to Mack’s motion 
for partial summary judgment. Docket 27 at 6 n.4.                         
government’s specific indication of what witnesses it wishes to depose who may 
have information as to liability, the early stage of discovery, and the timing of 
Mack’s motion, the Court finds it appropriate to permit the government    

additional time to conduct discovery as it pertains to the issue of liability. 
Thus, Mack’s partial motion for summary judgment on the issue of negligence 
is denied.                                                                
      b.  Whether partial summary judgment on the issue of scope of      
         employment is appropriate.                                      

    On the issue of whether Galarza’s alleged conduct occurred within the 
scope of his employment with the USPS, the government has not identified any 
relevant information it expects to obtain through further discovery that would 
create a genuine dispute of material fact. See Bell v. Young, 4:21-CV-04134-
LLP,
2022 WL 4482855
, at *19 (D.S.D. Sept. 27, 2022) (denying plaintiff’s 
request to defer ruling due to his failure to present any evidence or specific 
allegations sufficient to raise a genuine issue of material fact). In addition, the 
government has admitted this issue in both its answer and its response to 
Mack’s statement of undisputed material facts. See Docket 8 ¶ 10; Docket 25 
¶¶ 1, 20. Under these circumstances, the Court finds no basis to defer ruling 
on Mack’s motion for partial summary judgment as to the issue of scope of 
employment.                                                               
    The parties agree that Galarza was acting within the scope of his    
employment at the time of the incident. Docket 22 ¶ 20; Docket 25 ¶ 20. They 
also agree that on August 19, 2023, at approximately 11:15 a.m., Galarza was 
driving from the Summit Office to the Peever Office, and that such travel was in 
the course and scope of his employment duties with the USPS. Docket 22 ¶ 1; 
Docket 25 ¶ 1; see Docket 1 ¶ 10; Docket 8 ¶ 10. Therefore, and based on the 
undisputed facts before the Court, the Court finds that Galarza was acting 

within the scope of his employment with the USPS at the time of the accident 
and grants Mack partial summary judgment on this issue.                   
    Accordingly, it is hereby                                            
    ORDERED that the Court takes judicial notice of the fact that Galarza 
pled guilty to and was convicted of careless driving under SDCL § 32-2-8 and 
that the judgment of conviction and sentence was entered by the state court. It 
is further                                                                
    ORDERED that Mack’s motion for partial summary judgment on the       

issue of negligence, Docket 20, is denied without prejudice. It is further
