MEMORANDUM AND ORDER
MONTI L. BELOT UNITED STATES DISTRICT JUDGE
This matter is before the court on a Rule 60(b)(1) motion for relief from judgment by Kansas AFL-CIO Benefit Plan and Trust (hereinafter “the Plan”) and Kansas AFL-CIO Association (hereinafter “Employer”). (Doc. 77). Plaintiff has filed a response opposing the motion. (Doc. 79).
Plaintiff filed this action in February of 2011 claiming the Plan had unlawfully reduced his retirement pension in violation of ERISA. The Plan and Employer denied the allegation and claimed that plaintiff, the former administrator of the Plan, was liable for violation of fiduciary duties imposed by ERISA.
The record shows that discovery began in this case in March of 2011 and that it included initial disclosures, written interrogatories, and requests for production. Numerous witnesses were deposed, including Wil Leiker (Employer’s former Executive Vice President and Plan administrator), Jim DeMars (Plan’s ERISA consultant), Steve Cooper (Plan’s former actuary), Ron Eldridge (Employer’s former Executive Secretary), and Andy Sanchez (Employer’s then-Executive Secretary).
A pretrial order filed January 10, 2013 set forth the parties’ contentions and claims. (Doc. 55). Plaintiff asserted that a 1997 Plan amendment had increased the maximum available pension benefit from 70% to 85%. Plaintiff began receiving the 85% benefit when he retired in 2006, but the Plan and Employer thereafter reduced his pension, saying the benefit level had been improperly raised by plaintiff without Board approval. Plaintiff alleged in the pretrial order that defendants violated ERISA’s anti-cutback rule by reducing his pension to a 65% level. The Plan and Employer asserted that the 1997 amendment raising the maximum to 85% was invalid and Employer therefore “corrected the plan benefit formula ... [to] the formula in effect in 1994, namely, 70% of pay....” The pretrial order included a stipulation between the parties that the Plan’s pension benefit formula “was increased in 1994 and was 70% of pay [for] persons with 15 more years of service” such as plaintiff.
The court conducted a bench trial from March 12-14, 2013, and issued a comprehensive Memorandum Decision on August 28, 2013. Among other things, the court found plaintiff had improperly adopted the 1997 amendment without Employer’s approval. As a result, plaintiff was liable to the Plan in the sum of $40, 067 for violation of fiduciary duties and for engaging in prohibited transactions. Because the 1977 amendment was invalid, defendant’s refusal to pay plaintiff an 85% pension did not violate ERISA’s anti-cutback rule. But plaintiff additionally argued the reduction of his pension to 65%, instead of 70%, was a violation of the rule. As to that point, the court found that although Employer had voted in 2007 to reduce pensions to a 65% level, it subsequently ratified a 70% benefit. Doc. 73 at 40-41. Moreover, defendants conceded the appropriate benefit level in 1994 was 70%. Thus, a reduction of plaintiff’s pension below a 70% level would violate the anti-cutback rule. The court noted the evidence about whether plaintiff was actually being paid a 65% or a 70% benefit was somewhat unclear, but on the whole it indicated plaintiff was only receiving a 65% benefit. The court’s order noted that if this was incorrect, defendants could file a motion for reconsideration. No motion was filed. Because the court could not compute the exact benefits owing, it directed the parties to confer and file a joint statement of the benefits due under the court’s findings.
The parties filed a joint statement on October 1, 2013. (Doc. 74). It included a stipulation “that plaintiff DeHoff has been underpaid by [the Plan] since December 2007. He is entitled to receive the difference between 70% and the 65% he was paid, ” and it set forth the precise amounts owing. The following day, October 2, 2013, the court entered a final judgment incorporating the figures provided by the parties. (Doc. 75). The judgment included a finding that plaintiff was entitled to recover $16, 294 from the Plan for past pension underpayments and a monthly pension going forward of $3, 259.01. On the crossclaims, the judgment provided that plaintiff was liable to the Plan and Employer in the amount of $40, 067.
On November 12, 2013, plaintiff applied for a writ of execution. (Doc. 76). The following day, counsel for the Plan and Employer filed a motion for relief from judgment. The motion asserted that the Plan “did not know in advance about the Pretrial Order terms as to the benefit amount or Joint Statement and did not consent to them, as Defendant’s counsel believed that he knew, based on a different version of the 2007 Plan restatement (which was never adopted) he had received from an employee of the third party pension administrator (DeMars Pension Consulting Services).” (Doc. 78 at 1). Defense counsel provided affidavits from himself, from Wil Leiker, and Bruce Tunnell (Employer’s current Executive Vice President and Plan Administrator). Collectively, they asserted that defense counsel mistakenly believed that a 70% benefit had been approved by Employer in 1994, and, as a result, defense counsel had entered into stipulations in the pretrial order and joint statement to that effect without the consent of Employer or the Plan.
II. Rule 60(b)(1).
Rule 60(b)(1) provides that “on motion and just terms, the court may relieve a party or its legal representative from a final judgment ... for the following reasons: (1) mistake, inadvertence, surprise, or excusable neglect;...” This “mistake” provision allows for reconsideration of judgments where a party has made an excusable litigation mistake or an attorney in the litigation has acted without authority from a party. See Cashner v. Freedom Stores, Inc., 98 F.3d 572, 576 (10th Cir. 1996). But it is not available when a party seeks to undo the consequences of its deliberate acts. Yapp v. Excel Corp., 186 F.3d 1222, 1231 (10th Cir. 1999). A litigation mistake is generally not excusable unless it is one the party “could not have protected against, such as counsel acting without authority.” Yapp, 186 F.3d at 1231. Mere “carelessness by a litigant or his counsel does not afford a basis for relief under Rule 60(b)(1).” Pelican Production Corp. v. Marino, 893 F.2d 1143, 1146 (10th Cir. 1990).
A motion under Rule 60(b)(1) must be made “within a reasonable time, ” and in no event more than one year after entry of the judgment. Fed.R.Civ.P. 60(c)(1).
Plaintiff contends the motion for relief from judgment is untimely and is otherwise improper. (See Doc. 79 at 5). The court agrees that defendants have unreasonably delayed in seeking relief from the effects of a stipulation that dates back to the pretrial order and which permeated the litigation. The stipulation was mentioned and relied upon time and time again in this case. Even accepting everything in defendants’ affidavits as true, the allegations do not demonstrate sufficient grounds for relief from the judgment. Defendants are essentially asking to reopen a matter they had a fair and full opportunity to litigate, under circumstances which would result in substantial and unfair prejudice to plaintiff. Cf. Mullin v. High Mountain, 182 Fed.Appx. 830, 2006 WL 1520187 (10th Cir. 2006) (a rule 60(b)(1) motion is not timely merely because it is filed within one ...
