Trаcey Daley (“Daley”) filed a complaint against the Marriott Health Plan (the “Plan”) 1 and Empire Blue Cross/Blue Shield (“Empire”) for breach of contract under state law and breach of fiduciary duty under the Employee Retirement Income Security Act, 29 U.S.C. §§ 1001-1461 (“ERISA”). Daley alleged that the Plan failed to. provide mental-health coverage in accordance with Nebraska’s mental-health рarity law. The Plan and Empire filed a motion for summary judgment. The district court 2 granted the motion because it concluded that the Nebraska mental-health parity law is preempted by ERISA as to self-funded ERISA plans.
In a separate action, Daley filed a similar complaint against Marriott International, Inc. (“Marriott”), in its capacity as administrator of the Plan. Marriott moved to dismiss the comрlaint based on the doctrine of res judicata. The district court 3 granted the motion and alternatively held that the Nebraska mental-health parity law is preempted by ERISA as to Marriott’s self-funded ERISA plan.
Daley appeals both judgments. For the reasons discussed below, we affirm both judgments.
*892 I. BACKGROUND
Daley is an employee of Marriott Corporation, Inc., a subsidiary of Marriott. Daley is a particiрant in the Plan, which is self-funded and sponsored by Marriott and governed by ERISA. 4 Marriott is the administrator of the Plan, and as such, under the Plan it has the “sole and absolute final discretion to determine eligibility for plan benefits, to construe the terms of the plan, and to resolve any factual issues relevant to benefit eligibility or benefit enrollment.” Pursuant to an agreement with Marriott, Empire performs third-party аdministrative and claims-processing services for the Plan.
Under the terms of the Plan, in-network outpatient mental-health visits are fully covered, subject to a co-payment. Such coverage, however, is subject to a plan-year maximum of thirty visits and a lifetime maximum of 200 visits.
In 2000, Daley began receiving outpatient treatment for an unspecified mental-health condition. In 2000 and 2001, she incurred claims exceeding the plan-year maximum of thirty visits. Empire denied those claims and Daley’s appeals of those claims on the basis that Daley’s visits exceeded the plan-year maximum. Daley argued that Nebraska’s mental-health parity law, Neb.Rev.Stat. §§ 44-791 to 795 (2000), prohibited the Plan from imposing any limits on mental-health coverage. 5 The Plan, through Empire, took the position that the Nebraska mental-health parity law does not apply to the Plan because the law is preempted by ERISA.
Daley decided not to pursue an optional appeal of her denied claims to Marriott. Instead, on January 20, 2003, Daley filed a complaint against the Plan and Empire for breach of contract under state law and breach of fiduciary duty under ERISA § 409, 29 U.S.C. § 1109, based on the Plan’s failure to рrovide mental-health coverage in accordance with the Nebraska mental-health parity law.
Daley made three attempts to amend her complaint to add Marriott as a defendant. First, on August 29, 2003, Daley filed a motion to add Marriott as a defendant. The magistrate judge 6 denied the motion, citing Daley’s failure to comply with Rule 15.1 of the Local Rules of the United States District Court for the District of Nebraska, which requires the moving party to attach a proposed amended pleading to the motion. 7 Then, on December 26, 2003, Daley filed another motion to *893 amend her complaint seeking to add Marriott as a defendant, to expand the time-frame of denied claims to 2003, and to add an allegation of untimely notices of those additional claim denials. The magistrate judge denied this motion because the proposed amended complaint attached to the motion failed to reference Marriott, the party Daley intended to add as a defendant. 8 Finally, on January 23, 2004, Daley filed a motion to reconsider the denial of her motion to amend and attached a corrected proposed amended complaint which substituted Marriott as a defendant in placе of the Plan, expanded the timeframe of denied claims, and added an allegation of untimely claim denials. The magistrate judge construed the, motion as a renewed motion for leave to amend and denied it. 9
The Plan and Empire moved for summary judgment, arguing that ERISA preempts the Nebraska mental-health parity law. On June 1, 2004, the district court granted the motion, concluding that Daley’s claims were based on a state law that, as applied to self-funded ERISA plans, is preempted by ERISA. See Daley v. Marriott Health Plan, No. 8:03CV26 (D. Neb. June 1, 2004) (“Daley I ”).
Meanwhile, on February 19, 2004, Daley filed a lawsuit against Marriott in its capacity as Plan administrator (“Daley II ”). The complaint in Daley II is the same as the complaint filed in Daley I, except in the following respects: (1) Marriott, as opposed to the Plan and Empire, is the named defendant in Daley II; (2) the Daley II complaint contains an allegation of additional claim denials based on the plan-year limit since the filing of Daley I; and (3) the Daley II complaint contains an allegation of untimely notices of those additional claim denials. Marriott moved to dismiss Daley II based on the doctrine of res judicata. On June 18, 2004, the district court granted the motion on res judi-cata grounds and alternatively held, like the district court in Daley I, that Daley *894 failed to state a claim because her claim relied on a state law that, as applied to self-funded ERISA plans, is preempted by ERISA.
Daley now appeals the district court’s adverse grant of summary judgment in Daley I. She also appeals the district court’s dismissal of Daley II.
II. DISCUSSION
A. Daley I
Daley argues that the district court erred in holding that the Nebraska mental-health parity law is preempted by ERISA.
10
“Because ERISA preemption is a question of federal law involving statutory interpretation, we review the district court’s decision de novo.”
Ark. Blue Cross & Blue Shield v. St. Mary’s Hosp., Inc.,
Before addressing Daley’s argument that ERISA does not preempt the Nebraska mental-health parity law, we must explain the analytical framework of ERISA preemption. “ERISA comprehensively regulates employee pension and welfare plans.”
Baxter v. Lynn,
However, ERISA contains an exception to the general rule of preemption, which is referred to as the “savings clause.” Under the savings clause, a state law that regulates insurance is “saved” from ERISA preemption. 29 U.S.C. § 1144(b)(2)(A).
11
ERISA’s “deemer clause,” in turn, “exempt[s] self-funded ERISA plans from state laws that ‘regulate] insurance’ within the meaning of the savings clause.”
FMC Corp. v. Holliday,
Daley cites three cases in support of her argument against ERISA preemption of the Nebraska mental-health parity law:
Express Scripts, Inc. v. Wenzel,
Whether the Nebraska mental-health parity law is saved from preemption is not the determinative issue. Because the law “relates to” an ERISA employee benefit plan, ERISA’s deemer clause exempts Marriott’s self-funded Plan from application of Nebraska’s mental-health parity law.
See FMC Corp.,
B. Daley II
We now turn to the issue of whether thе doctrine of res judicata bars
Daley II.
We review de novo a dismissal based on res judicata grounds.
Lundquist v. Rice Mem’l Hosp.,
1. Same Cause of Action
For purposes of res judiсata, the term “cause of action” has been given a “more practical construction” than the “rather rigid and technical construction” it was given at common law.
Ruple v. City of Vermillion,
Daley argues that her additional allegations in Daley //-subsequent mental-health benefit denials under the Plan since the filing of Daley I and untimely notices of those denials-are new causes of action which should not be barred by res judicata. We reject this argument because it improperly rеlies on a rigid and technical view of the term “cause of action.” Taking a more practical view, the two additional allegations in Daley II are part of the “same nucleus of operative facts” as Daley I: the Nebraska mental-health parity law, the plan-year limit on outpatient mental-health visits under the Plan, and the Plan’s denial of Daley’s claims for mental-health benefits in excess of the plan-year limit. Regardless of the number of claim denials and whether Daley received timely notice of those denials, the wrong for which she seeks redress-the denial of her claims based on the plan-year limit-is the same in both Daley I and Daley II. Therefore, we conclude that Daley II is based on the same cause of action as Daley I.
2. Privity
Although we conclude that
Daley I
and
Daley II
are based on the same cause of action, the doctrine of res judicata will not bar
Daley II
against a defendant which was not a party to
Daley I.
Marriott, the only named defendant in
Daley II,
was not a party to the
Daley I
lawsuit in which the Plan and Empire were the named defendants. An exception exists, however,
*897
when a defendant stands in privity with a defendant in the prior suit.
Headley v. Bacon,
Daley argues that the doctrine of res judicata does not bar Daley II against Marriott because Marriott, a non-party to Daley I, does not stand in privity with Empire. Daley does not address the issue of whether Marriott, the Plan administrator, is in privity with the Plan. She misses the point that in order for her argument to succeed, Marriott must not be in privity with either defendant in Daley I. Daley’s argument fails, therefore, because we conclude that Marriott stands in privity with the Plan.
Marriott and the Plan are in privity because they have “a close relationshiр, bordering on near identity.”
Gurley,
In Daley I, Marriott’s interests as the administrator of the Plan were identical to the Plan’s interests. The Plan provides that the Plan administrator “is responsible for all discretionary matters arising in the interpretation, operation, and administration of the Plan.” In addition, the Plan’s summary plan description designates Marriott’s General Counsel as the agent for service of legal process and states that only the Plan administrator or its officially designated representatives are authorized to speak for the Plan. Therefore, in Daley I, Marriott, in its capacity as the Plan administrator, was the entity concerned with ensuring that Plan benefits be provided in aсcordance with the terms of the Plan. In fact, had Daley somehow prevailed in Daley I, Marriott, the Plan administrator, would have been obligated to disburse benefits under the Plan accordingly. Therefore, we conclude that the Plan and Marriott are in privity for purposes of res judicata.
Accordingly, because Daley II involves the same parties or their privies and is based on the same cause of action as Daley I, we affirm the district court’s dismissal of Daley II on res judicata grounds.
III. CONCLUSION
Fоr the reasons discussed above, we affirm the district courts’ judgments in Daley I and Daley II.
Notes
. Although Daley captioned the Plan as the "Marriott Health Plan,” the proper legal name of the Plan is the “Marriott International, Inc. Medical Plan.”
. The Honorable William Jay Riley, United States Circuit Judge for the Eighth Circuit, sitting by designation.
. The Honorable Laurie Smith Camp, United States District Judge for the District of Nebraska.
. The record does not reflect whether Daley is still an employee of Marriott and a participant in the Plan.
. Neb.Rev.Stat. § 44—793(1)(a)(i) provides that a health insurance plan "shall not establish any rate, term, or condition that places a greater financial burden on an insured for access to treatment for a serious mental illness than for access to treatment for a physical health condition ...." Section 44-792(4) defines "[r]ate, term, or condition” as "lifetime limits, annual payment limits, and inpatient or outpatient service limits. Rate, term, or condition does not include any deductibles, copayments, or coinsurance .... ” In other words, the Nebraska law requires annual and lifetime limits on mental-health benefits to be on par or better than limits on physical-health benefits.
. The Honorable F.A. Gossett, United States Magistrate Judge for the District of Nebraska.
. Rule 15.1 provides: "A party who moves for leave to amend a pleading (including a request to add parties) shall attach to the motion an unsigned copy of the proposed amended pleading. Except as provided in these rules or by leave of court, the proposed amended pleading so submitted shall be a complete pleading which, if allowed to be filed, shall supersede the pleading amended in all respects; no portion of the prior pleading may be incorporated into the proposed amended pleading by reference.”
. We note that in addition to failing to reference Marriott, the motion also was untimely. The magistrate judge's pre-trial scheduling order set August 29, 2003, as the deadline for Daley to file any motions to add parties or amend pleadings.
. On appeal, Daley argues that the magistrate judge erred in denying her motion for leave to amend her complaint. We cannot review Daley's challenge to the merits of the magistrate judge's order denying this nondispositive pretrial motion because Daley failed to file any objections to such order with the district court. Under Rule 72(a) of the Federal Rules of Civil Procedure, if a party fails to file with the district judge timely objections to an order of a magistrate judge on a nondispositive pretrial motion, such party "may not thereafter assign as error a defect in the magistrate judge’s order." Fed.R.Civ.P. 72(a);
See Lee/Millsap v. Wright,
. In her opening brief to this Court, Daley states that the "primary issue” in this case is whether the Nebraska mental health parity law is preempted by ERISA. However, in her reply brief, Daley asserts for the first time that ERISA preemption of the Nebraska law is not the issue in this case. She now claims that she is attempting to enforce against the Plan the federal mental-health parity law set forth in 29 U.S.C. § 1185a.
We view this as "an attempt to amend one’s pleadings in an appellate brief.”
Dorothy J. v. Little Rock School Dist.,
. The savings clause provides: "Except as provided in subparagraph (B), nothing in this subchapter shall be construed to exempt or relieve any person from any law of any State which regulates insurance, banking, or securities.” 29 U.S.C. § 1144(b)(2)(A). In
Kentucky Ass’n of Health Plans, Inc. v. Miller,
. The deemer clause provides: “Neither an employee benefit plan ... nor any trust established under such a plan, shall be deemed to be an insurance company or other insurer, bank, trust company, or investment company or to be engaged in the business of insurance or banking for purposes of any law of any State purporting to regulate insurance companies, insurance contracts, banks, trust сompanies, or investment companies.” 29 U.S.C. § 1144(b)(2)(B). As we noted above, although the Supreme Court refined the savings-clause analysis in
Miller,
. The additional argument advanced by Daley that summary judgment should not have been granted because an issue of fact exists as to whether Empire is a fiduciary under ERISA is, therefore, irrelevant.
. In Ruple, the Court explained that at common law,
if someone brought debt to recover possession of a specific thing, and the action was dismissed, a second action, this time in the form of detinue, would not be barred. The second case, it was said, was on a different "cause of action.” ... It is now said, in general, that if a case arises out of the same nucleus of operative fact, or is based upon the same factual predicate, as a former action, that the two cases are really the same "claim” or "cause of action” for purposes of res judicata. Since the forms of action have been abolished, and joinder of claims and amendment of pleadings are liberally permitted in both federal and state courts, there is no reason to give a claimant more than one fair chance to present the substance of his or her case.
Ruple,
