State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
Summary 
Controversy has arisen over the funded status of many state and local government pension plans. 
It has been reported that several of these plans have not fully funded their future obligations and 
they could face substantial future shortfalls. While there is considerable debate over the extent 
and the possible causes of these shortfalls, some estimates have placed the combined unfunded 
liabilities anywhere from hundreds of billions of dollars to over $3 trillion. Governments facing 
investment losses combined with lower revenues are looking at ways to address these shortfalls 
and protect their fiscal stability. State governors and legislators in several states have proposed 
and enacted various modifications to their pension plans. There have been calls for modification 
of federal, state, and local laws affecting these pension plans and the benefits provided to 
participants and beneficiaries. This report provides an overview of how public pension plans are 
regulated at the federal and state level, discusses selected legal issues that may arise in attempting 
to remedy or prevent public pension plan underfunding by modifying public pension plan 
benefits, and addresses possible federal regulation of state and local public pension plans.

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
Introduction 
Public pension plans, also referred to as governmental plans, are generally plans that provide 
retirement or deferred income to employees of the U.S. government, a state government or its 
political subdivision, or any agency or instrumentality of those governments.1 According to a 
2010 GAO report,2 approximately 20 million employees and over 7 million retirees and survivors 
are covered by state and local government pension plans, typically through a traditional defined-
benefit plan.3 Recently, questions have been raised about the funded status of many public 
pension plans, as it has been reported that many of these plans are facing substantial future 
funding shortfalls. Concerns have been raised that these liabilities could jeopardize the fiscal 
stability of state and local governments. 
While there is considerable debate over the cause and the extent of public pension plan 
underfunding, some of the estimates have placed the combined unfunded liabilities anywhere 
from hundreds of billions of dollars, to over $3 trillion.4 In an effort to address these issues, 
legislators and others have argued to reform public pension plans and the benefits they offer. In 
2010 alone, over 20 states introduced or passed legislation aimed to reduce or otherwise modify 
pension plan benefits for current or future retirees,5 and more proposals have been introduced this 
year. This report provides an overview of how public pension plans are regulated at the federal 
and state level. It discusses selected legal issues that may arise in attempting to remedy or prevent 
public pension plan underfunding, in particular, by changing plan benefits. This report will also 
briefly address possible federal regulation of state and local public pension plans.

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
Regulation of Public Pension Plans 
Employment-based retirement benefits6 are largely governed by two federal laws, the Employee 
Retirement Income Security Act (ERISA) and the Internal Revenue Code.7 In general, these two 
laws address two types of pension plans: defined benefit and defined contribution plans. Under a 
defined benefit plan, an employee is promised a specified future benefit, traditionally an annuity 
beginning at retirement. Benefits often are based on average pay and years of service. To fund the 
plan, an employer makes contributions to the common pension fund that are actuarially expected 
to grow through investment to cover the promised benefits. Under the terms of the plan, 
employees may make contributions as well. Most public pension plans are traditional defined-
benefit plans.  
A defined contribution plan (e.g., a 401(k) plan) is one in which the contributions are specified, 
but not the benefits. A defined contribution plan (also called “an individual account” plan) is one 
that provides an individual account for each participant that accrues benefits based solely on the 
amount contributed to the account and any income, expenses, and investment gains or losses to 
the account. The employee bears the investment risk in a defined contribution plan. Some state 
and local governments maintain defined contribution plans, and there have been proposals in 
various states to switch from a defined benefit to a defined contribution plan. 
Enacted in 1974, ERISA provides a comprehensive federal scheme for the regulation of pension 
and other employee benefit plans offered by private-sector employers. While ERISA does not 
require an employer to offer employee benefits, it does mandate compliance with its provisions if 
such benefits are offered. Title I of ERISA imposes various federal standards aimed at protecting 
the interests of plan participants and beneficiaries, including reporting and disclosure, vesting, 
participation, funding, fiduciary duty, and civil enforcement requirements. Title IV of ERISA 
created a plan termination insurance program, under which pension benefits are paid to plan 
participants and beneficiaries up to a statutory maximum if the benefits cannot be paid by the 
employer. Public pension plans are generally exempt from these provisions of ERISA, 8 but may 
be subject to federal regulation under the Internal Revenue Code.9 
The Internal Revenue Code grants certain tax benefits to “qualified” retirement plans.10 Among 
these tax advantages, employer contributions to a qualified plan on behalf of its employees are tax 
deductible for the employer. In addition, qualified retirement plan participants do not pay tax on 
                                                
6 This report does not address Social Security, which is funded in part by is funded by payroll taxes paid by covered 
workers and their employers. See CRS Report RL33544, Social Security Reform: Current Issues and Legislation, by 
Dawn Nuschler. 
7 It should be noted that other federal laws govern various aspects of public pension plans. For example plans may be 
subject to the Civil Rights Act of 1964, the Age Discrimination in Employment Act (ADEA), and the Family and 
Medical Leave Act.  
8 While it is often expressed that governmental plans are exempt from ERISA, this statement is technically incorrect. 
Governmental plans may be subject to Title II of ERISA, which amended the Internal Revenue Code to impose 
requirements for plan qualification that a plan must meet in order to receive favorable tax treatment. These qualification 
requirements in the Code parallel many of the provisions in Title I of ERISA. However, as discussed infra, 
governmental plans are exempt from a number of these qualification requirements. 
9 It should be noted that there are different types of governmental plans subject to different requirements under the 
Internal Revenue Code. See, e.g., 26 U.S.C. § 403(b); 26 U.S.C. § 457. This report will not focus on these differences. 
10 In general, for purposes of this report, a qualified plan generally means an employer-sponsored pension plan that 
meets the requirements set forth under 26 U.S.C. § 401(a); eligible plans are described in 26 U.S.C. § 457.

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
employer contributions or the benefits they accrue in the pension plan until the participant (or 
beneficiary) takes a distribution. Given that state and local governments do not pay federal taxes, 
the tax benefit for employer contributions is irrelevant to them. However, public pension plans 
must be qualified so that the plan participants can avoid paying taxes on their pension benefits 
until the benefits are actually received. In order to be a qualified plan under the Internal Revenue 
Code, pension plans must meet several requirements. Governmental plans, however, are only 
subject to a subset of the qualification requirements that private-sector pension plans must meet.11 
In many cases, public pension plans are subject to different requirements under the Internal 
Revenue Code than private-sector plans, including certain less stringent pre-ERISA requirements 
for vesting and funding. 
Aside from the requirements set out in the Internal Revenue Code, public pension plans are 
primarily regulated under state statutes, local ordinances, and state constitutions. These laws 
typically address the basic features of public pension plans, including eligibility, contributions, 
and types of benefits provided, and the laws vary widely from jurisdiction to jurisdiction.12 While 
public pension plans have no guarantor of plan benefits, states generally have constitutional or 
statutory provisions that dictate how pension plans are to be funded, protected, managed, or 
governed.13  
Benefit Accrual and Vesting Requirements 
In evaluating whether pension plan benefits may be modified, requirements for benefit accrual 
and vesting are implicated. Under federal law, both ERISA and the Internal Revenue Code 
provide requirements for benefit accrual, which generally refers to the rate at which benefits are 
earned by a plan participant. Both federal laws prohibit private-sector pension plan amendments 
that eliminate or reduce benefits already accrued by plan participants.14 This prohibition is 
commonly referred to as the “anti-cutback rule.”15 However, private-sector pension plans may be 
free to freeze accrued benefits, reduce the rate at which benefits will accrue in the future, or 
eliminate future benefit accruals altogether. In other words, under the anti-cutback rule, past 
benefit accruals are protected, but future benefits accruals can be modified. Governmental plans 
are exempt from the anti-cutback rule. Therefore, analysis of the changes that may be made to 
accrued benefits under a public plan is a state-by-state inquiry.  
While accrued benefit refers to the amount of benefits earned, vesting occurs under federal law 
when a plan participant’s accrued benefit is considered to be non-forfeitable.16 ERISA and the 
                                                
11 For a list of the Internal Revenue Code requirements that public pension plans must meet, see Barry Kozak,

Efforts,” CCH Planning Guide, Benefit Practice Portfolios (July 2008). 
12 U.S. GOV’T ACCOUNTABILITY OFFICE, GAO-07-1156, STATE AND LOCAL GOVERNMENT RETIREE BENEFITS: CURRENT 
STATUS OF BENEFIT STRUCTURES, PROTECTIONS, AND FISCAL OUTLOOK FOR FUNDING FUTURE COSTS 20 (2007). 
13 Legal protections may also be recognized under common law. See id. 
14 29 U.S.C. § 1054(g); 26 U.S.C. § 411(d)(6). 
15 Certain exceptions to the anti-cutback rule may apply. For example, ERISA allows for a plan to reduce accrued 
benefits by a retroactive amendment in certain cases where a plan is confronted with a “substantial business hardship.” 
See, e.g., ERISA § 204(g)(1), 29 U.S.C. § 1054(g)(1) (citing ERISA § 302(d)(2), 29 U.S.C. § 1082(d)(2)). 
16 There can be confusion in understanding the difference between when benefits accrue and when benefits vest. As 
articulated by the Supreme Court, accrual is “the rate at which an employee earns benefits to put in his pension 
account.” Central Laborers’ Pension Fund v. Heinz, 541 U.S. 739, 749 (2004). Vesting, on the other hand, is “the 
process by which an employee’s already-accrued pension account becomes irrevocably his property.” Id.

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
Internal Revenue Code impose two general vesting requirements on private-sector defined benefit 
pension plans: one depending on age and one depending on length of service.17 Governmental 
plans are exempt from these federal vesting requirements. However, in order to be qualified, 
governmental plans must meet pre-ERISA vesting standards under the Internal Revenue Code, 
which include the requirement that upon plan termination or complete discontinuance of 
contributions, employees’ rights to benefits accrued as of the date of the termination or 
discontinuance are non-forfeitable, but only to the extent that the benefits are funded.18 States 
may also impose additional vesting requirements for pension benefits, and these can vary by state. 
Can State and Local Governments Modify Pension 
Benefits? 
Recently, in an effort to alleviate pension plan underfunding and protect state and local 
government budgets, governors and legislators in several states have proposed and enacted 
various modifications to their pension plans.19 Over the past few years, almost two-thirds of states 
have made some form of benefit and/or contribution change to their plans (e.g., reducing benefit 
levels, requiring higher employee contributions, or amending age and service requirements to 
lengthen the accumulation and shorten the distribution period of pension benefits).20 While the 
majority of changes are directed at future participants and/or benefit accruals, some of the 
changes affect current employees and retirees. Although states may not face obstacles in changing 
the pension benefits available for new employees, the issue is not as clear with respect to existing 
ones. As discussed below, certain legal parameters may affect the ability of state and local 
governments to amend their pension plans. 21 These parameters vary by state and depend on each 
state’s laws and constitutional provisions governing its retirement system, what these laws 
provide with respect to the protection of an individual’s pension benefits, and when any right to a 
pension benefit attaches.  
Courts have conceptualized the legislative modification of public employee pension plan benefits 
in different ways. Historically, most courts viewed public pensions as gratuities that could be 
amended at any time. Although it may not be controlling in the interpretation of a state law, the 
Supreme Court has historically found that statutes providing retirement benefits to pensioners 
create a mere “expectancy” that may be modified, revoked, or suspended by the authority 
granting it through subsequent legislation.22 However, this view has now been abandoned in most

states, and public employee pension benefits are generally afforded greater protection under 
current state and constitutional law.23 This is, at least in part, because many courts now 
characterize public plan pensions as deferred compensation—that an employee is entitled to these 
benefits for work that has already been performed.24  
Public Pension as a Contractual Right 
In rejecting the gratuity approach to public pensions, many state courts have found that based on 
common law, state statute, or state constitution, public pension benefit plans create a contract 
between the state and plan participant.25 If a contract is found to exist between the state or local 
government and pension plan participants, then this can limit the ability of a state to amend its 
pension plans.26 In some states, there is a specific constitutional provision addressing protection 
for public pensions as contractual obligations.27 At least six states28 have a constitutional 
provision that, in general, explicitly provides that membership in, or accrued benefits from, a 
state’s retirement system creates a contract between the state and its employees that cannot be 
impaired. One lawsuit demonstrating the effect of this type of pension protection is McDermott v. 
Regan.29 In this case the New York legislature, in response to a state fiscal crisis, changed the 
funding method for the state’s retirement systems. The change had the effect of reducing the 
government’s contribution to the system. In finding that the state law violated the New York 
constitution,30 the court explained that the amendment depleted money in the fund and arguably 
destabilized the retirement system. Thus, it was an unconstitutional impairment of the pension 
funds. 
In the absence of a state constitutional provision expressly prohibiting the modification of 
pension benefits, a state’s statutes or case law may be found to provide contractual rights for state 
and local government employees to their pension benefits. 31 As noted above, if a contract is

U.S. 166 (1980). 
23 It should be noted that a small minority of state courts still view some public pensions as gratuities. See e.g., 
Haverstock v. State Public Employees Retirement Fund, 490 N.E.2d 357, 360-61 (Ind. Ct.App.1986)(“Where employee 
participation in the retirement plan is compulsory or mandatory, however, it is termed a pension. Pensions are mere 
gratuities springing from the appreciation and graciousness of the state. Under such a plan, the employee has no vested 
contract rights until he fulfills all conditions existing at the time of his application for benefits.”)

25 See Amy Monahan, Public Pension Reform: Legal Framework, Education, Finance & Policy, Vol. 5 (2010). 
26 Id. 
27 It should be noted that several states have provisions in their state constitutions that address protection of the state 
retirement system as a whole. Among other things, state constitutions address how public pension plans should be 
funded and provide that retirement system assets are exclusively for the purpose of the retirement system. See 2007 
GOV’T ACCOUNTABILITY OFFICE, note 12 supra, at 19. The protections discussed here concern the protection of the 
pension rights of an individual participant. 
28 These states include Alaska, Arizona, Hawaii, Illinois, Michigan, and New York.

30 Article V, Section 7 of the New York Constitution provides that “membership in any pension or retirement system of 
the state or of a civil division thereof shall be a contractual relationship, the benefits of which shall not be diminished or 
impaired.” 
31 While not nearly as common as a contractual right, it should be noted that rights to a pension benefit may be based 
on something other than a contract. For example, the New Mexico State Constitution provides that a pension benefit is

found to exist between the state or local government and pension plan participants, then this can 
limit the ability of a state to amend its pension plans. A public employee’s contractual right to an 
unaltered pension benefit may be protected under the Contract Clause of the U.S. Constitution or 
an analogous state constitutional provision.32 The Federal Contract Clause provides, “No state 
shall ... pass any ... Law impairing the Obligation of Contracts.”33 Although the language of the 
Contract Clause appears straightforward, its prohibition against state impairment of contracts is 
not absolute but rather “must be accommodated to the inherent police power of the state ‘to 
safeguard the vital interests of its people.’”34 The Contract Clause applies to contracts between 
private parties, as well as those where the state is a party to the contract.35 However, in general, 
instances where the state is impairing a contract for its own benefit invite more judicial scrutiny.36 
Based on Supreme Court jurisprudence, courts typically evaluate whether a state law violates the 
Contract Clause under a multi-pronged test. With respect to a public contracts, as a preliminary 
matter, courts may look at whether there is a contractual obligation that has been impaired.37 In 
order to determine whether a contractual relationship exists, a court may look to legislative intent 
to create a contract between the state and a private party.38 As the Supreme Court has explained, 
In determining whether a law tenders a contract to a citizen it is of first importance to 
examine the language of the statute. If it provides for the execution of a written contract on 
behalf of the state the case for an obligation binding upon the state is clear….The 
presumption is that such a law is not intended to create private contractual or vested rights 
but merely declares a policy to be pursued until the legislature shall ordain otherwise. He 
who asserts the creation of a contract with the state in such a case has the burden of 
overcoming the presumption.39 
State statutes that establish retirement plans generally do not address whether a contract is 
created; thus, ascertaining whether a contract exists for a public plan pensioner can, in some 
cases, be difficult.40

a property right. It states that “[u]pon meeting the minimum service requirements of an applicable retirement plan 
created by law for employees of the state or any of its political subdivisions or institutions, a member of a plan shall 
acquire a vested property right with due process protections under the applicable provisions of the New Mexico and 
United States constitutions.” N.M. Const. art. XX, § 22.

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
However, if it is established that a contract exists, one must then ascertain whether a plaintiff’s 
contractual rights are “substantially impaired.”41 Factors that courts have taken into account in 
determining whether a substantial impairment exists include whether a statute applies 
prospectively, or retroactively;42 disrupts a party’s “reasonable expectations” regarding an 
agreement; 43 or “alters its terms, imposes new conditions, or lessens [a contract’s] value.”44 In the 
context of public pensions, benefit formula changes, changes in plan funding sources or 
methodology, and the elimination of cost of living supplement payments have all been found by 
courts in certain instances to be substantial impairments of the pension contract. 45 But, in general, 
state law amendments that were not anticipated to have an effect on pension benefits or on 
employer rights and responsibilities may not be considered impairments.46 
If a substantial impairment exists, however, the state law may still be constitutional if “it is 
reasonable and necessary to serve an important public purpose.”47 This rule ensures that in 
impairing a contract, the state is protecting the broad public interest, rather than its own self-
interest. 48 As the Supreme Court has explained with respect to the impairment of public 
contracts, reasonableness must be considered “in light of the surrounding circumstances.”49 
Necessity depends upon two considerations: first, whether the impairment was essential or 
whether a less “drastic modification” was available, and also whether a state could have adopted 
an alternative means to bring about the desired end without impairing contract obligations.50 As 
the Supreme Court noted in U.S. v New Jersey, “a State is not completely free to consider 
impairing the obligations of its own contracts on a par with other policy alternatives. Similarly, a 
State is not free to impose a drastic impairment when an evident and more moderate course would 
serve its purposes equally well.”51 While some courts have found that a state’s desire to reduce

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
spending and avoid financial crisis is an important public purpose under which a modification of 
a contractual right is acceptable under the Contract Clause, 52 others have found to the contrary.53  
In addition, a number of state courts, such as in California, permit reasonable modifications to an 
individual’s pension benefits. However, “the modification must bear some material relationship to 
the purpose of the pension system and its successful operation; and any disadvantage to 
employees must be accompanied by comparable new advantages” 54 (e.g., an increased pension 
amount). Thus, as explained by one commentator, the idea is that public employees are not 
entitled to any particular terms of a pension, but of the substance of the benefit which they could 
reasonably expect to receive.55 It should be noted that courts may reach varying conclusions as to 
whether a more financially sound pension plan is a comparable advantage that may accompany a 
modification of pension benefits.56 
Attachment of Pension Rights  
While states that protect public pensions under contract principles typically evaluate a case under 
the legal standard discussed above, they reach varying conclusions based on when the contract is 
deemed to be formed, and what terms and conditions the contract includes.57 While courts 
generally find that the pension benefits of individuals who have already retired may not be 
diminished or impaired, this outcome is not as clear for current employees.58

State and Local Pension Plans and Fiscal Distress: A Legal Overview 
 
The ability of states to modify their pension plans for current employees varies depending when a 
contract is deemed to exist, and this varies from state to state.59 For example, in some states, 
courts have held that an employee’s right to a pension cannot be changed in any way that reduced 
the benefit that would be payable upon the day of hire or the first day the employee could 
participate in the plan.60 This view entitles plan participants the most generous amount of 
protection for their pension benefits, as employees have a right to accrue benefits in the future.61 
States may, however, alter the benefits available to new hires.62  
In other states, reductions in pension plan benefits could be prohibited when, under the terms of a 
state statute, a participant is eligible to receive a pension (e.g., the employee has fulfilled the 
plan’s service requirement).63 This approach is in line with federal requirements for private sector 
pension benefits. Under this view, retirement benefits must be provided for service already 
performed, but prospective plan modifications may still be acceptable. It is also possible that 
based on interpretation of a state statute, contractual rights to a pension take effect at other times. 
For example, interpreting an Ohio statute, one court found that the right to a pension benefit 
attached at retirement.64 
Despite the variation in when a contractual right to a public plan pension benefit begins, as noted 
above, state courts generally find that the benefits of individuals who have already retired may 
not be diminished or impaired.65 However, the modification of post-retirement benefits is 
currently being challenged by retired state workers in three states, Minnesota, North Dakota, and 
Colorado. The litigation is based on adjustments that the state legislatures made to post-retirement 
cost of living adjustments in an attempt to address pension plan underfunding.66 For example, in 
Minnesota, recently enacted legislation scales back an annual cost of living adjustment. Plaintiffs 
have claimed that they have a constitutional right to the use of a specific formula for future post-
retirement increases. On the other hand, the state defendants have argued that “nothing …

60 Brauer, supra note 21. See also, e.g., Olson v. Cory, 26 Cal. 3d 672 (Cal. 1980)(“A long line of this court’s decisions 
has reiterated the principle that a public employee’s pension rights are an integral element of compensation and a 
vested contractual right accruing upon acceptance of employment.”) See also Yeazell v. Copins, 98 Ariz. 109, 402 P.2d 
541 (1965).

63 For example, in Petras v. State Board of Pension Trustees, a retired schoolteacher sought to claimed he had an 
enforceable right to a pension calculated under the version of state law in effect when he began teaching in the state. In 
denying his claim, the Delaware Supreme Court opined that “it is clear that no contract exists between an employee and 
the State, concerning the state pension plan, unless and until the pension vests. This result is consistent with that 
reached in other jurisdictions… Because in 1964 the period for vesting of pensions was 30 years, Petras, who had only 
completed two years service before the [pension formula] provision was changed, had no vested right in that provision 
or, for that matter, in the plan as a whole. The General Assembly’s modification of the pension plan, therefore, did not 
violate any contractual right.”)(citations omitted). See also Baker v. Oklahoma Firefighters Pension & Retirement Sys., 
718 P.2d 348, 350-51 (Okla.1986) (contractual right begins when eligible to receive pension).

and pensions give rise to vested rights.”).

supports a promise to forever refrain from amending the [cost of living adjustment] formula.”67 It 
appears that a court has not yet ruled on the merits of these cases.  
Federal Legislation Affecting State and Local 
Governmental Pension Plans 
In order to address the issue of public pension plan underfunding, some have called for federal 
action. In the past, there have been efforts to regulate public pension plans similar to ERISA. In 
particular, following enactment of ERISA, various proposals were introduced that would have 
required public plans to meet various federal standards, such as reporting, disclosure, and 
fiduciary duty requirements.68 Legislative history indicates that Congress intentionally exempted 
these plans from ERISA for various reasons, most of which center around the differences inherent 
in regulating a private pension plan versus one sponsored by a state or local government.69 
Because of these differences, it was concluded that additional data and study were necessary 
before attempting to regulate public plans.70 Federalism concerns were also raised, based on the 
idea that regulating state and local pension plans would constitute impermissible federal 
interference in the affairs of state and local government. 71 However, the legal landscape has 
changed due to Supreme Court decisions issued after ERISA’s enactment in 1974.72 
While it appears that no proposals have been introduced in the 112th Congress to comprehensively 
regulate public pension plans, there has been discussion of possible federal legislation to allow 
states to declare bankruptcy, something that states cannot currently do, in order to avoid or reduce 
certain financial obligations, such as pension obligations.73 Another proposal addressing public 
pension plans, the Public Employee Pension Transparency Act, would require public pension plan 
sponsors to file various plan financial data with the Treasury Secretary, including plan assets at 
fair market value and plan liabilities at an interest rate based on the U.S. Treasury obligation yield 
                                                
67 Swanson et al. v. State of Minnesota, No.CV-lO-5285, (Dist. Minn. filed Aug. 18, 2010) at 36. 
68 See, e.g., H.R. 5144, Public Employee Pension Plan Reporting and Accountability Act (PEPPRA), 98th Cong. 2nd 
Sess., (1984); H.R. 4928 and 4929, Public Employee Retirement Income Security Act (PERISA), 97th Cong., 1st Sess. 
(1981).  
69 As explained in Rose v. Long Island R. Pension Plan, 828 F.2d 910, 914 (2nd Cir. 1987): 
The governmental plan exemption [to ERISA] was included for several reasons. First, it was 
generally believed that public plans were more generous than private plans with respect to their 
vesting provisions. Second, it was believed that “the ability of the governmental entities to fulfill 
their obligations to employees through their taxing powers” was an adequate substitute for both 
minimum funding standards and plan termination insurance. Finally, there was concern that 
imposition of the minimum funding and other standards ‘would entail unacceptable cost 
implications to governmental entities.’ (citations omitted). 
70 29 U.S.C. § 1231(a)(3). 
71 See, e.g., Feinstein v. Lewis, 477 F. Supp. 1256, 1261 (S.D.N.Y. 1979) (purpose of ERISA governmental exemption 
was to “refrain from interfering with the manner in which state and local governments operate employee benefit 
systems”), aff'd, 622 F.2d 573 (2d Cir. 1980).

curve.74 The bonds issued by governmental entities that do not comply with the disclosure 
requirements would lose their federal tax exemption. Among other things, the legislation also 
states that the federal government would not be liable for any obligation related to a shortfall in 
any public pension plan.
