MEMORANDUM AND ORDER Petitioner Nikodem Wtulich (“Wtulich”) seeks to have respondent Magda Filipkowska (“Filipkowska”) return their daughter AW to Poland.1 See Docket Entry (“DE”) 1 (Petition); Convention on the Civil Aspects of International Child Abduction, done at the Hague on October 25, 1980 (“the Convention”), T.I.A.S. No. 11,769, at 1, 22514 U.N.T.S. at 98, reprinted in 51 Fed. Reg. 10493 (1986); International Child Abduction Remedies Act, 22 U.S.C. §9001, et seq. On March 20, 2019, following a bench trial, I granted Wtulich’s petition. See Wtulich v. Filipkowska, 2019 WL 1274694, at *11 (E.D.N.Y. Mar. 20, 2019) (findings of fact and conclusions of law). Filipkowska now seeks a new trial on the basis of what she claims is newly discovered evidence. See DE 76; Fed. R. Civ. P. 59(a)(2); Fed. R. Civ. P. 60(b)(2). She also seeks a stay pending her pro se appeal of the order that AW return to Poland. See DE 85; Fed. R. App. P. 8(a)(1). For the reasons set forth below, I deny both motions.I. BackgroundI assume the reader’s familiarity with the facts of this case as summarized in my earlier decision. In short, AW was born in Poland in 2008, and Poland remained her habitual place of residence at the time her parents last agreed about where she should live. In 2013, Wtulich consented to have Filipkowska take AW with her for a three-month trip to the United States to attend a family wedding. Filipkowska has retained AW in this country ever since. She married after bringing AW to the United States, and she now and lives with her husband and AW in New Jersey, where AW attends school. AW’s passport expired in 2015. As of the time of the bench trial, Filipkowska reported that neither she nor AW had lawful immigration status in this country, and that she was unable to obtain a green card for her daughter. See Wtulich, 2019 WL 1274694, at *1-2.With the parties’ consent, I presided at a bench trial of the matter on April 23-24, 2018. See Wtulich, 2019 WL 1274694, at *1; DE 44; DE 50; DE 51; DE 53 (trial transcript (“Tr.”) pp. 1-58); DE 54 (Tr. pp. 59-145); 28 U.S.C. §636(c). After receiving the parties’ post-trial submissions, I granted Wtulich’s Petition on March 20, 2019. I concluded that Wtulich had established that Filipkowska wrongfully retained their daughter in the United States in violation of the Convention and that Filipkowska had failed to establish that AW was “well-settled” in the United States in the pertinent legal sense, or that Wtulich had acquiesced to AW’s remaining in the United States. See Wtulich, 2019 WL 1274694, at *11. The Clerk entered judgment on March 21, 2019. See DE 63.Filipkowska now claims she is entitled to a new trial because there is new evidence that AW is “well-settled” in the United States for purposes of the Convention. She reports that she and AW obtained green cards and that she is now legally, gainfully employed. She also cites as new evidence certain emails between herself and Wtulich which she says demonstrate that Wtulich acquiesced to AW remaining in the United States. See DE 76-20 (“Memo. I”) at 3-5.2 In considering the motion I have reviewed the evidence Filipkowska submitted, Wtulich’s opposing memorandum, and Filipkowska’s reply memorandum. See DE 76-2 through DE 76-19 (exhibits); DE 77 (“Opp. I”); DE 79 (Reply); DE 80 (Filipkowska’s supporting affidavit); DE 80-1 (Filipkowska’s supplemental exhibit).On June 26, 2019, Filipkowska filed a motion to stay AW’s return to Poland pending the resolution of her appeal. See Fed. R. App. P. 8(a)(1); DE 85 (motion); DE 85-1 (“Memo. II”). Wtulich responded on June 28, 2019. See DE 87 (“Opp. II”).II. The Motion for a New TrialA. Applicable LawFilipkowska seeks a new trial or entry of a new judgment under Rules 59 and 60 on the ground that a litigant may “seek a new trial based upon newly discovered evidence and any other reason justifying relief from the operation of a judgment after trial.” Memo. I at 2 (citing Ilardi v. Bechtel Power Corp., 106 F.R.D. 567, 570 (E.D.N.Y. 1985)).A court may grant a new trial for “any reason for which a rehearing has heretofore been granted in a suit in equity in federal court.” Fed. R. Civ. P. 59(a)(1)(B). Where, as here, the trial was not before a jury, the court may “open the judgment…, take additional testimony, amend findings of fact and conclusions of law or make new ones, and direct the entry of a new judgment.” Fed. R. Civ. P. 59(a)(2). “Any such motion must be based upon manifest error of law or mistake of fact.” Burzynski v. Travers, 111 F.R.D. 15, 17 (E.D.N.Y. 1986) (internal citations omitted). “[A] trial court should not grant a new trial merely because the losing party can probably present a better case on another trial.” Ball v. Interoceanica Corp., 71 F.3d 73, 76 (2d Cir. 1995). To the contrary, a court should order a new trial only if the “‘refusal to take such action appears…inconsistent with substantial justice.’” LiButti v. United States, 178 F.3d 114, 118 (2d Cir. 1999) (quoting Fed. R. Civ. P. 61). Indeed, courts “routinely reject” such motions “in the absence of extraordinary circumstances.” New York v. Shinnecock Indian Nation, 2008 U.S. Dist. LEXIS 9226, at *5-6 (E.D.N.Y. Feb. 7, 2008). Such extraordinary circumstances exist if the court “overlooked any relevant facts or legal authority,” if its factual findings or conclusions of law were erroneous, if there is a “supervening change in law,” or if there is newly discovered evidence. Saint v. United States, 243 F.R.D. 50, 52 (E.D.N.Y. 2007). Filipkowska seeks a new trial on the latter ground.Under both Rule 59 and Rule 60(b)(2), the standard for assessing a claim of newly discovered evidence is the same. See Metso Minerals, Inc. v. Powerscreen Int’l Distrib. Ltd., 833 F. Supp. 2d 282, 293 (E.D.N.Y 2011), rev’d on other grounds, 526 F. App’x 988 (Fed. Cir. 2013); Patel v. Lutheran Med. Ctr., 775 F. Supp. 592, 596 (E.D.N.Y. 1991). To succeed on a motion pursuant to Rule 60(b)(2), the movant bears the burden of showing:(1) the newly discovered evidence was of facts that existed at the time of trial or other dispositive proceedings, (2) the movant was justifiably ignorant of them despite due diligence, (3) the evidence is admissible and of such importance that it probably would have changed the outcome, and (4) the evidence is not merely cumulative or impeaching.United States v. Int’l Bhd. of Teamsters, 247 F.3d 370, 392 (2d Cir. 2001) (internal citations omitted). Evidence that was clearly available at the time of the proceeding is not newly discovered. See Pryor v. Berryhill, 286 F. Supp. 3d 471, 474 (E.D.N.Y. 2017) (internal quotation omitted) (citing Whitaker v. New York University, 543 Fed. App’x 113, 114 (2d Cir. 2013)); Sorenson v. Wolfson, 2015 WL 4095197, at *3 (S.D.N.Y. July 7, 2015) (newly discovered evidence “must have been unknown to the movant at the time of trial, and the movant must have been excusably ignorant of the facts — meaning that the facts could not have been discovered by a diligent search”) (internal citations omitted).B. Analysis1. Post-Trial Developments: AW’s Green Card and Filipkowska’s JobFilipkowska and AW received green cards on approximately July 24, 2018. Memo I at 3; DE 76-2. In explaining her trial testimony that she and AW were unable to secure green cards, Filipkowska asserts “that she was misinformed by her immigration agency that a passport was required to get AW a green card. It turns out that was a mistake[.]” Memo. I at 3. Filipkowska further claims that, since the conclusion of the trial, she has begun working legally, and her salary “ has risen to approximately $60,000 per year.” Id. at 5.Filipkowska’s evidence relating to the green cards and her higher salary fail the first element of the applicable test: namely, that newly discovered evidence must establish facts that existed at the time of trial. As Filipkowska acknowledges, AW obtained her green card more than three months after the trial ended. “At the time of the trial,” as Filipkowska’s counsel acknowledges, Filipkowska and “AW did not possess green cards.” DE 76 5.The evidence of Filipkowska’s higher salary likewise fails the test’s first prong because it relates to a post-trial development. Filipkowska relies on a letter written in April 2019 describing a job that began in May 2018 — after the trial had already ended. See DE 80-1. That is not newly discovered evidence within the meaning of the applicable rule.The evidence also fails the test’s second requirement that Filipkowska’s ignorance of the new evidence was justifiable. At the trial in 2018, Filipkowska testified that she had not even applied for a green card for AW because she had come to understand that doing so would be futile so long as AW lacked a valid passport. See Tr. at 94-95, 103-04, 110-11. She now contradicts that testimony and swears that she and her husband applied for AW’s green card in 2017. See DE 76-5 (Filipkowska Affidavit) (“Filipkowska Aff.”) 63. If this most recent statement is true, Filipkowska’s ignorance of it at the time of the trial was inexplicable, let alone justifiable.Even if the evidence of AW’s green card and Filipkowska’s employment qualified as newly discovered evidence, which they do not, such evidence is not “of such importance that it probably would have changed the outcome” of this case. Teamsters, 247 F.3d at 392 (internal citation omitted). “[T]he default presumption under the Convention” is that, in the absence of certain conditions, “a child shall be returned to the state from which she originally was wrongfully removed.” Lozano v. Alvarez, 697 F.3d 41, 51 (2d Cir. 2012) (emphasis in the original). AW’s immigration status and Filipkowska’s employment status were not the only reasons I granted Wtulich’s petition, or even the predominant ones in determining whether AW should be allowed to remain in this country because she is settled here. See Lozano, 697 F.3d at 57 (“While courts have consistently found immigration status to be a factor when deciding whether a child is settled, no court has held it to be singularly dispositive.”). I also considered the extent to which AW has been trapped in a drawn-out legal dispute since 2016 and AW’s initial lack of a stable residence. See Wtulich, 2019 WL 1274694, at *8-9.Finally, relying on the post-trial developments Filipkowska cites would ignore an important part of the analysis that led me to reject the defense that AW is settled in this country. That is, all of developments that have acclimated AW to life in the United States and made it easier for her to stay here spring from Filipkowska’s wrongful retention of the child in violation of Wtulich’s right to have her returned to Poland. Relying on Filipkowska’s improved financial stability, or her post-trial success in obtaining a green card for AW, would frustrate the Convention’s objective “to dissuade parents…from engaging in gamesmanship with a child’s upbringing in order to secure an advantage in an anticipated custody battle.” Gitter v. Gitter, 396 F.3d 124, 134 (2d Cir. 2005).2. Recently Submitted EmailsFilipkowska also seeks a new trial on the basis of several email messages between herself and Wtulich that she claims to have discovered after the trial when her cousin Wojciech Kicak did some “troubleshoot[ing work on] her email system” and adjusted the “IMAP folder date filters settings[.]” DE 76-4 (“ Kicak Aff.”) 4. She contends that these “new” emails demonstrate that Wtulich “acquiesced to the child remaining in the United States,” that he “made no mention of returning the child to Poland,” and that he “had access to the child and visitation.” Memo. I at 4. As explained below, the emails on which Filipkowska relies (both those in her initial motion papers, and additional ones submitted with her Reply) are not newly discovered and, because they serve only to provide cumulative impeachment of Wtulich’s testimony, would not have altered the outcome if admitted at trial.Filipkowska’s failure to introduce at trial the evidence on which she now relies is plainly the result of insufficient diligence. Filipkowska claims that her “IMAP folder date filters settings” precluded her from viewing and retrieving emails more than two years old. See Reply 9; Kicak Aff. 4. That assertion is at odds with the fact that Filipkowska did offer forty emails in evidence at trial, including several that were then more than two years old. See, e.g., Respondent’s Trial Exhibits (“Resp. Ex.”) C, D, U-X. Even assuming that the “IMAP folder date filters settings” on Filipkowska’s computer led her to find some emails but miss others until later, the problem was one Filipkowska easily resolved when she had her cousin work on the device and adjust a single setting. See Reply 9. Her failure to get such help while preparing for trial renders her claimed ignorance of the emails during the trial unjustifiable. See Teamsters, 247 F.3d at 392; Opals on Ice Lingerie v. BodyLines, Inc., 425 F. Supp. 2d 286, 293 (E.D.N.Y. 2004) (finding that a litigant’s “feeble efforts to locate” a document demonstrated a failure to exercise the due diligence required for relief). Equally unpersuasive is Filipkowska’s argument that she asked Wtulich to produce in discovery the emails he had written to her, but that he instead provided emails she had written to him. See Reply
