Mullin v. Balicki

¶5OPINION OF THE COURT

¶6FUENTES, Circuit Judge.

¶7A little over two years into the civil-rights suit brought by Joan Mullin (“Mul-lin”) over the tragic prison suicide of her son, Robert Mullin (“Robert”), Mullin’s attorney received a discovery document with the potential to reshape the case. A previously undisclosed investigative report about, the night Robert died contained statements by fellow New Jersey inmates about a prison guard who allegedly refused Robert’s requests for psychiatric assistance—and urged Robert to kill himself instead. But while Mullin’s attorney received this report mid-case, it was not reviewed in a timely fashion. Instead, due to a clerical error, the disc containing the relevant disclosures was misfiled, and not fully accessed until about ten months later. By that time, Mullin’s operative complaint—premised on a less direct knew-or-should-have-known theory of Robert’s vulnerability to suicide—had already been dismissed in large part. The District Court denied Mullin’s request for leave to amend her complaint, due in part to the delay caused by counsel’s error and, after additional motion practice, granted summary judgment in favor of the one remaining defendant, bringing the litigation to a close.

¶8Mullin’s appeal encompasses both the dismissal of her operative complaint and the order denying further leave to amend. The latter is the focus of this opinion. For the reasons set forth below, we conclude that the decision denying leave to amend amounted to an impermissible exercise of discretion. Some of the factors relied upon to deny leave are not supported by the record or are at odds with our case law. And while we do not intend to minimize counsel’s mistake, it does not, standing alone, support denying leave to amend. Accordingly, we will vacate the order denying leave to amend and will remand for further proceedings.

¶9I. Background 1

¶10A. Robert’s Death and Mullin’s Initial Investigation

¶11During the early morning hours of January 17, 2009, New Jersey prisoner Robert Mullin hanged himself with a bedsheet that he had fashioned into a noose. The twenty-nine-year-old Robert had been in and out of prison for the better part of a decade, in part due to his ongoing struggles with substance abuse. While serving out his latest sentence at a halfway house, Robert was found in possession of contraband. As a result, he was transferred to New Jersey’s Central Reception & Assignment Facility (“Assignment Facility”), where he was assessed and assigned to an area of the facility that did not feature extensive or individualized supervision by *146staff. It was there, in his Assignment Facility cell, that he took his own life—less than- a day after entering the Facility.

¶12In the aftermath, Robert’s mother, Joan Mullin,' sought answers. -What few were given, however, were incomplete and at times inaccurate. In one instance, she was told that her son had died at a completely different facility, the Trenton Psychiatric Hospital—an error repeated on his death certificate. Despite some slow progress, she continued to lack key information about the final days and hours of Robert’s life and the people and entities to whom his care was entrusted.

¶13B. Mullin Files the Original Complaint in January 2011

¶14Despite this state of affairs, Mullin filed suit in the District of New Jersey shortly before the two-year mark of Robert’s death,2 raising state tort claims and constitutional vulnerability-to-suicide claims (the latter of which is a variation on a constitutional claim alleging deliberate indifference to a serious medical need). The complaint focused on the defendants’ alleged failure to provide Robert with the level of care, treatment, and monitoring that he needed, and that was required by prison policy for someone with his history of depression, self-harm,- and substance abuse; Mullin alleged that Robert was placed in a cell that was inadequately supervised and altogether inappropriate for a person with a history of suicide attempts—a decision .made all the-more inexcusable by the medical history and recent relapse into drug addiction that his custodians failed to properly review or otherwise heed.

¶15Mullin named a variety of defendants, several of whom were employed by the State of New Jersey and represented by the New Jersey Attorney General’s office. We will refer to these as the “State Defendants.”

¶16C. Mullin Twice Amends Her Complaint

¶17Mullin twice amended her complaint to both flesh out the facts—in part to account for interim discovery she, received. from non-State defendants—and to modify the list of defendants. In particular, Mullin sought to add Officer Nicholas Dimler, the Assignment Facility, guard who, according to the medical examiner’s report, was the last person (who wasn’t a fellow inmate) to see Robert alive—and the one who later discovered his body.

¶18Mullin’s first - attempt to amend, filed in response to the defendants’ initial Rule 12 motions, was granted in part and denied in part. Among other things, the Magistrate Judge determined that the proposed amended complaint lacked sufficient detail of Dimler’s involvement in Robert’s death and did not state a plausible claim for relief against him. Under these constraints, Mullin filed her first amended complaint (“FAC”) in December 2011,

¶19- After obtaining ■ additional discovery, Mullin again asked to amend in July 2012, arguing in part that she Could now plead a' viable claim against Officer Dimler. Mullin alleged essentially that Officer Dimler knew or should have known of Robert’s history of-suicide and psychiatric illness; that Dimler failed to review records that would have alerted him to Robert’s condition; and-that Dimler failed to follow prison policies and reasonable practices pertaining to inmates with Robert’s vulnerabilities. This time, the Magistrate *147Judge allowed Muffin's amendment-to include the revised allegations against Officer Dimler, .finding them to be “plausible” instead of merely possible.3 Muffin’s Second Amended Complaint (“SAC”), the operative complaint for the remainder of the litigation in the District Court, was then filed in September 2012. The SAC, like its predecessors, was met with Rule 12 motions to dismiss.

¶20D. While the Motions to Dismiss are Pending, Mullin Receives New Evidence in Discovery

¶21Although Muffin had obtained some discovery by the time the SAC was filed— almost two years into the litigation—she -had received no disclosures from the State Defendants and, by extension, from the Department of Corrections or the State itself. The State Defendants finally made two separate document disclosures, pursuant to an amended pretrial scheduling order, while their motion to dismiss was pending. Both sets bear on Muffin’s later attempt at améndment, although for very different reasons.

¶22One set of disclosures, from July 2013 (the “July 2013 disclosures”), contained information on various prison policies regarding suicide watch, close custody, and screening procedures employed by thé Assignment Facility. For instance, Mullin received a policy manual on “Special Needs Inmates,” covering inmates who suffer from certain psychiatric disorders and are “unable to meet the functional requirements of incarceration without mental health treatment.”4 It appears that the July 2013 disclosures did not pertain to Robert individually or contain information relating to the night he died. ■

¶23More important was a set of disclosures from April 2013 (the “April 2013 disclosures”) that, by contrast, contained information directly relevant to Robert and his history in the prison system. Among the new revelations were statements from fellow inmates about a prison guard who allegedly ignored Robert’s requests for mental, health services and, instead, told him to commit suicide.

¶24These statements were contained in a February 2009 Department of Corrections Administrative Investigation Report (“the Report”). According to the Report, a previously unknown guard, Officer X,5 interacted with Robert over his only evening at the facility, and may have been the last person (instead of Officer Dimler) to see Robert alive. The details of Officer X’s interaction with Robert, as related in the Report, were very disturbing. Six inmates, who had been interviewed about Robert hours after his suicide—close in time to the incident, and potentially before having any opportunity to.- get their stories straight—volunteered that they had heard Robert ask Officer X to see “psych,” and that Officer X had refused Robert’s request and taken no action. Three of the inmates went further: Officer X not, only refused assistance, but egged Robert on, telling him that he “might as. well kill [him]self.”6 The Report therefore suggested Officer X’s actual awareness of, and indifference to, Robert’s condition. The Report elsewhere revealed that Robert was in fact classified as a “special needs” inmate requiring enhanced levels of care.7*148Thus, although Officer X, interviewed later, flatly denied both parts of this account, the Report had the potential to reframe and support Mullin’s case.

¶25E.Counsel’s Error: The April 2013 Discovery is Misplaced

¶26But this potential would go untapped— at least for the time being—because Mullin did not initially know that it had been received. The April 2013 material was subdivided and Bates stamped as “DOC MULLIN 0001-392” and “CONFIDENTIAL MULLIN 0001-305.”8 Due to a clerical error, Mullin’s attorney failed to review the CONFIDENTIAL MULLIN material that contained the Report and other relevant documents. The disclosures had been provided by the State Defendants on two optical discs, one for the MULLIN material and the other for the CONFIDENTIAL MULLIN material. The attorney asked her staff to print out both discs for review, but one disc was printed twice and the other was misfiled in the folder of an unrelated matter. And because Mullin’s attorney was not aware of the new material, she did not move to further amend her complaint, even though an earlier scheduling order had suggested that further amendment for truly “new” discoveries might be allowed.

¶27F.The District Court Dismisses the SAC

¶28With Mullin unaware of the new discovery, the SAC—whose allegations were premised on the theory that the defendants should have known, based on Robert’s answers to intake questions and his transfer/medical records, that he was particularly vulnerable to suicide—remained the operative complaint. Thus, unlike prior motions to dismiss, which had been interrupted by Mullin’s requests to amend, these Rule 12 motions were resolved on the merits, with the District Judge directly addressing Mullin’s claims for the first time. In a November 2013 decision, the District Court granted the State Defendants’ motion to dismiss .in its entirety, although the Court allowed Mullin’s claims against the Assignment Facility intake purse to proceed to summary judgment and, thus, the case remained ongoing.9

¶29G.Realizing the Mistake, Counsel Moves to Amend

¶30Despite indications that something was missing, Mullin’s attorney only realized her mistake in February 2014—ten months after the April 2013 disclosures, and three months after the District Court had dismissed the SAC in large part— during a conversation with attorneys for non-state defendants who were privy to the CONFIDENTIAL MULLIN material. In the flurry of activity that followed, Mul-lin’s attorney advised the District Court of her mistake and, after being told by the court to delay formally moving to amend until a pending reconsideration motion was resolved. Mullin moved in August 2014 to amend her complaint to include information from the April and July 2013 disclosures. In addition to repleading claims against Dimler and other previously dismissed defendants, Mullin’s proposed Third Amended Complaint (“TAC”) incorporated the material from the April and July 2013 disclosures and added Officer X, a fellow guard, and four supervisors as defendants.

¶31*149H. Leave to Amend is Denied

¶32The presiding Magistrate Judge denied leave to amend, finding that Mullin’s delay, was undue and that the defendants would suffer prejudice if amendment were allowed. The Judge also suggested in passing that claims against new parties would not “relate back” for limitations purposes under Rule 15(c). The Magistrate Judge did not directly address the futility of the proposed amendment, which had not been raised by the State Defendants. After Mul-lin objected to the Magistrate Judge’s order, the District Court affirmed it in a short decision.10 Mullin timely appealed.

¶33II. Discussion 11

¶34A. Rule 15 and Standard of Review

¶35Leave to amend is governed by Rule 15, “Amended and Supplemental Pleadings,” which generally conditions amendment on the court’s leave or the opposing party’s written consent.12 Lacking a time limit or an outer bound on when amendment is permissible, the Rule instructs courts to “freely give leave [to amend] when justice so requires.”13 This liberal amendment regime helps effectuate the “general policy embodied in the Federal Rules favoring resolution of cases on their merits.”14

¶36In determining whether leave to amend might reasonably be denied, courts are guided by the Foman factors, named for the Supreme Court’s decision in Foman v. Davis, 371 U.S. 178, 83 S.Ct. 227, 9 L.Ed.2d 222 (1962). Denial of leave to amend can be based on undue delay, bad faith or dilatory motive on the part of the movant; repeated failure to cure deficiencies by amendments previously allowed; prejudice to the opposing party; and futility.15 The Foman factors are not exhaustive, allowing a court to ground its decision, within reason, on consideration of *150additional equities; such as judicial economy/burden on the! court16, and the prejudice denying leave to amend would cause to the plaintiff.17 All factors are not created equal, however, as “prejudice to the non-moving party is the touchstone for the denial of an amendment.”18

¶37A decision on whether to permit amendment of the pleadings generally falls within the District Court’s discretion. It follows that we review for abuse of that discretion, except where amendment is denied for legal reasons drawing de novo review (such as when the proposed amendment would 'fail to state a claim).19 If we find an error in the District Court’s reasoning, we exercise our own discretion in determining whether we will nevertheless affirm “if ... • the District Court’s [remaining] findings would support denial of leave to amend.”20

¶38While abuse of discretion is ordinarily a deferential standard of-review, it has bite in this context; the District Court’s discretion, circumscribed by the Rule 15’s directive in favor of amendment, must be “exercised within the context of liberal pleading rules.”21 Moreover, leave to amend is" not an all-or-nothing proposition. Relying on the Foman factors, courts can choose instead to impose reasonable conditions on the right to amend in lieu of a pure grant or denial. Specifically, a court “may use its discretion to impose conditions on the allowance of a proposed amendment as an appropriate means of balancing the interests of the party seeking the amendment and those of the party objecting to it,” such as by “narrow[ing] the scope of the amendment if it considers the request too broad.”22

¶39*151One additional background consideration applies in civil rights cases like this one. In our Circuit, “district courts must offer amendment [in civil rights cases]—irrespective of whether it is requested—when dismissing a ease for failure to state a claim unless doing so would be inequitable or futile.”23 By contrast, plaintiffs in “ordinary” civil litigation—commercial disputes, for instance— must take affirmative steps to obtain amendment in the face of dismissal.24

¶40B. Analysis

¶41Although the District Court gave reasons of its own when declining to set aside the Magistrate Judge’s order, we are really reviewing the Magistrate Judge’s exercise' of discretion in entering the order, and not the District Court’s deferential review of the same. Accordingly, we will focus our review on the Magistrate Judge’s analysis of the Formn factors.

¶42X. Undue Delay

¶43The “undue delay” factor recognizes that a gap between when amendment becomes possible and when it is actually sought can, in certain circumstances, be grounds to deny leave to amend. While simple delay cannot justify denying leave to amend by itself, delay that is “undue”— a delay that is protracted and unjustified—r can place a burden on the court or coun-terparty, or can indicate a, lack of diligence sufficient to justify a discretionary denial of leave.25 As there is “no presumptive period; in which ... delay -becomes ‘undue,’ ”26 the .“question of undue delay requires, that we focus on the movant’s reasons for not amending sooner” , while “bearing in mind the liberal pleading philosophy of the federal rules.”27 “Following this principle, we have refused to overturn denials of motions for leave to amend where the moving party offered no cogent reason for the delay in seeking the amendment.” 28

¶44The Magistrate Judge broke down'the delayin' this case into two discrete periods. First, the Judge assessed the delay arising from the July ' 2013 “policy” discovery, which Mullin’s - counsel consciously chose not to use in an earlier amendment. Second,, the Judge assessed the more-significant delay arising from the misplaced April 2013 discovery, which' counsel was not aware of until February 2014.

¶45i) July 2018 Discovery

¶46Mullin’s attorney argued that her reasons for declining to amend immediately upon receiving the July 2013 discovery were reasonable, and that the delhy before *152she first brought the material to the Court’s attention was thus not undue.29 She explained that she received the discovery after the-return date for the motions to dismiss, assumed the period for requesting amendment was closed, and further assumed that the Court would not reopen the record. Counsel also argued that amending was unnecessary. She believed that the SAC’s description of various policies and procedures was enough to survive the motions to dismiss, and that the meaning of the various policies of procedures would become clearer after she had received additional discovery.

¶47The Magistrate Judge found these reasons to be unconvincing, explaining that the closing-of-the-record point was “difficult to understand,” as “[Mullin] has not refrained from seeking leave from the Court for various reasons.”30 The Magistrate Judge also thought that counsel’s delay was impermissibly “tactical,” resulting in “waiting until the Motions to Dismiss were largely granted, and then asking for a ‘do-over.’ ”31 Deciding that this delay was not supported by a cogent reason, the Magistrate Judge deemed it “clearly undue.”32

¶48We disagree in part with the Magistrate Judge’s reasoning, and in particular with suggestion that counsel’s “tactical” decision transformed the delay into one that was undue. While we have disdained a wait-and-see approach to amendment, our major cases doing so fall in the post-judgment posture discussed above.33 More recently, wé have cautioned against over-reading the scope of some of those earlier cases.34 Further, the decisions spurning a wait-and-see approach are “standard” civil disputes.35 This, by contrast, is a civil rights case, with the attendant requirement in our case law that an opportunity to amend be presumed. In the ordinary course, a civil rights plaintiff would not expect a modest wait-and-see approach to constitute undue delay by itself—-unless egregious or excessive, or if some other factor rendered the delay undue.

¶49Our normal civil rights rule is put to the test in this matter, however, given the sheer complexity of the proceedings, as well as the fact that Mullin was previously granted leave to amend.36 It is certainly reasonable to think that there may be some situations where a civil rights plaintiffs pre-dismissal actions, or a court’s informal testing of the merits of *153the pleading, might count against granting amendment. But this case does not present such a situation. For one, although Mullin amended twice before, the second amendment (leading to the SAC) can be viewed as a perfection of the first, partially unsuccessful amendment.37 For another, her pleadings had never actually been formally evaluated by the District Court, and “the mere fact that a defendant files a motion to dismiss is not necessarily sufficient to put a plaintiff on notice that the court will find his complaint to be deficient.” 38

¶50Perhaps most important is that the SAC was informally tested on the merits before the motion to dismiss was resolved—and received a clean bill of health from the same Magistrate Judge, who opined that it passed muster under Twombly/Iqbal.39The Magistrate Judge’s decision was, of course, not binding on the District Court, let alone on us. But it does suggest that Mullin’s “tactical” approach to the dismissal cannot be fairly called dilatory or contumacious, in light of the solicitude given in civil rights cases and the prior suggestion from the Magistrate Judge that the motion to dismiss would fail.

¶51ii) April 2013 Discovery

¶52The April 2013 discovery—the disclosures containing the Report—presents a thornier problem. About ten months passed between the time the State Defendants sent Mullin’s attorney the April 2013 disclosures and the time the attorney realized that she had misplaced and failed to review them. Certainly, Mullin had a “reason” for not amending sooner: she was unaware of the evidence that she had been provided.40 The issue is whether this can suffice as a reason at all. We will, for the moment, disregard the issue of prejudice and instead look to whether, prejudice notwithstanding, the delay was “undue.”

¶53In addressing counsel’s error, the Magistrate Judge focused on the “many opportunities plaintiff had to realize that the disc was missing and to follow up or at least make inquiry,” stating further that “no inquiry was made until counsel for defendants made Plaintiffs counsel aware of the oversight during a conversation in February 2014.”41 Several “clues” should have alerted counsel to the missing discovery: (1) the initial April 2013 cover letter, which referred to the production of confidential materials; (2) the subsequent production in July 2013 of additional CONFIDENTIAL documents with bates numbers following the “missing” range, which should have indicated that the “missing” range had already been provided42; and (3) an October 2013 interrogatory response that pointed to the Report but did not separately provide it. The Magistrate Judge concluded that counsel’s “lack of diligence” was to blame, given the “repeated opportunities and repeated clues” that “should have made a diligent attorney aware that something was missing”; that there was “no *154inquiry made ... leads to the inescapable conclusion that the [April 2013 discovery] delay was in fact undue.”43'

¶54Beginning with this last point, the record does not entirely support the Judge’s conclusion that Muffin’s attorney failed to make “inquiries.” To the contrary, she continued to ask the Attorney General’s office for relevant discovery; the record contains, for instance, a June 2013 email to the Attorney General where counsel complains that nothing relevant to her constitutional claims has been obtained from the State Defendants.44

¶55However, the central question is whether this is the sort of error by an attorney that can be excused. The Magistrate Judge indicated only that the error “should not be excused,”45 but, as explained below, something more ls required.

¶56It is well established that “clients must be held accountable for the acts and omissions of their attorneys.”46 In some circumstances, the Federal Rules allow fpr a court to relieve a party from adverse consequences arising out of “mistakes” or “excusable neglect,” which are often not the party’s but the attorney’s.47 In that context, we have conducted an “equitable” inquiry into the circumstances surrounding a party’s failure, balancing the factors of prejudice to the non-movant, the length of the delay, the reason for the delay, and the movant’s good faith.48

¶57While misunderstandings based on law or procedure rarely constitute excusable neglect, clerical errors have been found to do so, taking “into account whether the mistake was a single unintentional incident (as opposed to a pattern of deliberate dilatoriness and delay), and whether the attorney attempted to correct his action promptly after discovering the mistake,” as a “mistake could occur in any attorney’s office, no matter how well run.”49 An omission caused by careless-néss, evén if within counsel’s control, may therefore be excusable.50

¶58Rule 15, which governs amendment, does not mention excusable neglect or mistake, but this is in- line with Rule 15’s general omission of any enumerated substantive or procedural. limitation on amendment. And based on the similarities *155between the Rule 15 test and the excusable neglect analysis, mistakes, omissions, or neglect, should be evaluated with similar solicitude under Rule 16 as they would be under a Rule with an explicit “excusable neglect” condition.

¶59Here, even assuming the worst— that the delay ran at least ten months, and that Mullin’s attorney failed to realize the error despite clues to the contrary—we cannot say that the mistake here was per se inexcusable, rendering the delay “undue.” It was' apparently the result of a single core error, the kind that could affect any law firm no matter how well run; there is no indication of any similar error elsewhere in the litigation; and the defense has not shown a pattern of similar faults or omissions.

¶60Neither the State Defendants nor the District Court questioned the attorney’s story that a clerical error led to the CONFIDENTIAL MULLIN materials being misplaced and misfiled. The record prior to March 2014 betrays no indication that Mullin or her attorney was aware of the Report or the related materials; as late as November 2013, Mullin’s attorney referred to the April 2013 disclosure as having produced nothing new or revelatory.51 Nor is there indication that Mullin could have obtained the CONFIDENTIAL MULLIN documents before she did. And when the mistake was discovered, counsel moved swiftly to bring it to the Court’s attention; the delay prior to the filing of the formal motion to amend was due to a scheduling order delaying consideration of amendment until reconsideration had been granted or denied.52

¶61For the above reasons, we disagree with the Magistrate Judge that the delay attributable to the April 2013 discovery was “inescapably]” undue.53 The record indicates that counsel followed up on documents that appeared to be missing; while counsel undoubtedly erred, with disastrous consequences for her client, the Magistrate Judge did not properly inquire as to whether the mistake was excusable in context, or from when the delay should have been measured. These considerations should be addressed on remand..

¶62.2. Prejudice

¶63As set forth above, prejudice to the non-moving party has long been the “touchstone” for' the denial of leave to amend.54 Here, the State Defendants had argued that the “numerous motions to amend” and other briefings had led them to expend significant resources on the litigation, and they further objected to Mullin’s “adding completely new defendants at this late *156stage of the litigation.”55 They asked the Magistrate Judge to “intercede by denying [amendment] and putting a stop to what seems like an endless cycle.”56

¶64The Magistrate Judge largely agreed with this line of argument. In a short discussion on prejudice, the Judge found that “[t]he current defendants, as well as those who have already been dismissed, have spent significant resources on this litigation, and they would essentially be forced back to square one.” With regard to the proposed defendants, there was “nothing beyond speculation to support the notion that ... there would not be prejudice to them in defending on the merits.”57 In the summary section, the Judge wrote that “allowing the amendment at this point of the litigation, after so much motion practice, would only cause further delay, to the prejudice of the parties.”58

¶65At the outset, the arguments against amendment advanced here and by the State Defendants on appeal do not connect prejudice to the additional delay caused by the mistake of Mullin’s attorney. Rather, these claims of prejudice would have applied with near-equal force had Mullin timely moved to amend immediately upon obtaining the April 2013 disclosures. Accordingly, we view the “delay” complained of here as referring to the pendency of the litigation as a whole and not to the delay in seeking to amend once the CONFIDENTIAL MULLIN documents were disclosed.

¶66Thus framed, we again disagree with the Magistrate Judge’s analysis. Mul-lin appears to be largely without fault for the years that passed before she obtained the CONFIDENTIAL MULLIN documents which radically altered her understanding of the night Robert took his own life. The State Defendants have not argued that she could have obtained the Report earlier, or that there was a hint of the proposed new defendants—and especially Officer X—in any of the discovery documents prior. While the State Defendants áre within their rights to comply only with those discovery obligations actually due under law, they cannot persuasively rely on resulting delay as a source of prejudice.59

¶67It was also not improper for Mullin to replead dismissed defendants and claims in her proposed amended complaint. At the time she filed her proposed TAC, Mullin may not have decided whether she intended to pursue the already dismissed claims and parties on appeal, and including them in the proposed TAC preserved that right. Because an amended complaint supersedes the original, “parties voluntarily dropped from an amended complaint do not remain in the case.”60 Claims omitted from an amended complaint remain in the case only if previously dismissed on “legal grounds, rather than due to a lack of factual specificity.”61 Dropping parties and dropping claims can therefore lead to abandonment later in the case and *157on appeal. Thus, to the extent that the Magistrate Judge counted this against Mullin with regard to prejudice or judicial economy, it was error to do so; since the abandonment rule applies only to claims or parties “voluntarily” dropped, allowing amendment but conditioning it on omission of previously dismissed claims or parties does not trigger the rule, and is the preferred way to resolve the problem.

¶68It is thus not correct to say that granting leave to amend would put the defendants back at square one or perpetuate an infinite cycle. The Magistrate Judge would have been entitled to rely on the District Court’s earlier dismissal opinion in determining whether previously dismissed defendants should remain in the case, and could have set further conditions on amendment, discovery, and so on. The “cycle” of motions practice interrupted by amendment requests based on new evidence remains a risk only for as long as discovery remains open.62 And because Mullin did not appeal the dismissal of any defendants other than Dimler, or the subsequent grant of summary judgment for the intake nurse, any challenges relating to those decisions have now been abandoned.63

¶69In sum, while the defendants have undoubtedly expended resources over the course of the litigation, and would have to expend additional effort were amendment allowed, their case for prejudice is thin. A defendant that possesses an explosive document unknown to the plaintiff may use the legitimate litigation strategies at hand to delay disclosure of that document until absolutely necessary, but that delay cannot thereafter form that defendant’s argument for prejudice if it leads to a belated request to amend. Because the State Defendants did not persuasively articulate a theory of prejudice, and because the Magistrate Judge’s discussion relied on factors that appear to have been allowable litigation choices on Mullin’s behalf, we will vacate for reconsideration of this factor.

¶703. Judicial Economy

¶71Judicial economy is an equitable consideration that can be considered in deciding whether amendment should be allowed. It is uncommonly a factor that stands entirely alone, separate and apart from prejudice and factors relevant to whether a delay was “undue.”64 Considerations include judicial efficiency and effective case management.65

¶72The Magistrate Judge appeared to consider judicial economy by discussing the work already done by the Court: the “almost four years” that had passed since its filing, at least “eight conferences” that had been held with the parties, and the extensive motions practice that included “at least four motions to dismiss.”66 The Magistrate Judge also referred to the District Court’s work “in preparing a 40-page opin*158ion, which would be rendered moot if the amendment were allowed to proceed.”67

¶73While the litigation had doubtlessly been frustrating, and Mullin’s apparent minimization of the many stumbles throughout is discouraging, the Magistrate Judge’s focus on the past inappropriately constrains the scope of the judicial economy inquiry. The difficulty in managing the litigation thus far is certainly salient, but simply tallying up the number of motions, conferences (of any type),‘and opinions sheds little light on whether future management of the case would encounter similar difficulties. The length of the District Court’s opinion on dismissal, and the effort behind it, are also of uncertain weight, especially in light of this Circuit’s default presumption in favor of amendment in civil rights cases.

¶74As cast in this, case, “judicial'economy” sounds almost like a sanction -for prior perceived errors. As presented, it does not currently support the Magistrate Judge’s decision to deny leave to amend.

¶754. Relation Back and Timeliness

¶76The Magistrate Judge summarily addressed, and the parties have briefed before us, the' doctrine of “Relation Back.” This refers to the operation of Rulé 15(c), which allows certain new claims and new parties added in an amended complaint to “relate back” to the date of filing of the original complaint for statute of limitations purposes if certain ponditions are met.68 While. courts are permitted to combine the question of whether amendment should be granted with the issue of whether the proposed amendment relates back,69 the two inquiries are analytically distinct; relation back is a test of the legal viability of the proposed amendment, and not a discretionary factor weighing in favor of or against amendment.70 Thus, in certain cases, the-“better approach” is to treat leave to, amend and relation back/timeliness separately, determining first whether amendment should be allowed under the discretionary factors, and only then passing on whether the complaint relates back or is otherwise timely.71

¶77On this record, we conclude that determining whether the complaint “relates back” is unnecessary, at least with regard to Mullin’s 42 U.S.C. § 1983 vulnerability-to-suicide constitutional claims brought against Officer X. The allegations against Officer X. would be timely on their face.

¶78The' accrual date of a' § 1983 claim is determined' under federal law.72 Generally, a constitutional claim under § 1983 accrues when the plaintiff knew or should have known of the injury upon which the action is based.73 A vulnerability-' to-suieide claim,- which is simply a more specific articulation of the Eighth Amendment rule that prison official's must not' be deliberately indifferent to a prisoner’s serious medical needs, requires showing (1) the existence of a particular vulnerability to suicide, (2) that a prison official knew or *159should have known of the individual’s particularly vulnerability, and (3) that the official acted with reckless or deliberate indifference to the particular vulnerability.74 The accrual of the claim is not tied solely to the prisoner’s suicide itself, but also to the unconstitutional act by the prison official that gives rise to the claim.75

¶79Here, the actual nature of the claim against Officer X was unknown to Mullin until the receipt, by counsel, of the April 2013 disclosures. Mullin’s claim against the prior State Defendants, premised on their alleged failure to be put on notice of Robert’s intake answers and transfer materials, stemmed from a different asserted injury. Officer X, by contrast, is alleged to have specifically known of Robert’s need for mental-health intervention and to have disregarded it. Mullin -would not have been put on notice of the elements comprising this separate injury by the pre-April 2013 disclosures, and the fact of Robert’s death itself did not otherwise cause the limitations period to start running. As discussed above, Mullin’s investigative'diligence has not been called into question. Thus, either innately or through the application of the discovery rule,76 the facts of this case show that Mullin could not have learned of the particular nature of this serious disregard of Robert’s mental state—or who was at fault—until she had obtained the Report or its equivalent. Mullin’s attempt- to amend therefore fell well within the applicable two-year limitations period if measured from the April 2013 disclosure date.77

¶80C. Summary

¶81For the above reasons, we conclude that the Magistrate Judge’s exercise of discretion was not within the boundaries contemplated by Rule 15 or the Woman factors, in light of the liberal pleading regime established by the Federal Rules. We remand for the Magistrate Judge or District Court to reassess the propriety of amendment under the proper framework. The Court may also wish to weigh whether the claims advanced by Mullin on the basis of the new discovery are meritorious in deciding whether amendment is warranted.78 If the Court nonetheless decides that the delay was undue or that the defendants’ have articulated past or potential future prejudice, the Court may wish to consider whether attaching conditions to amendment, or limiting amendment to certain claims and parties,' suffices to mitigate those concerns. Finally, while we have determined that the. § 1983 claims against Officer X would be timely if allowed to proceed, the District Court may consider whether Rule 15 relation back—including the application of the New Jersey fictitious party rule79—or other limitations doc*160trines suffice to render timely other claims against other proposed parties.

¶82III. Conclusion

¶83For the foregoing reasons, we will affirm in part, vacate in part, and remand.
