The district court in this race discrimination case properly granted summary judgment for the defendant employer based on law applicable at the time. In this appeal, however, we rely on the retroactive effect of the Lilly Ledbetter Fair Pay Act of 2009 to reverse summary judgment in part and allow appellants to pursue their claims of race discrimination under Title VII of the Civil Rights Act of 1964 and the Equal Protection Clause of the Fourteenth Amendment.
I. Factual and Procedural Background
We review a district court’s grant of summary judgment de novo. Antonetti v. Abbott Laboratories, 563 F.3d 587, 591 (7th Cir.2009). “We view the record in the light most favorable to the non-moving party and draw all reasonable inferences in that party’s favor.” Id., quoting Darst v. Interstate Brands Corp., 512 F.3d 903, 907 (7th Cir.2008).
A. The Plaintiff Officers
All three plaintiff-appellants — Kevin Groesch, Greg Shaffer, and Scott Allin— are white officers who were in good standing with the City of Springfield police department when they voluntarily resigned. At the times of their resignations, officers seeking reemployment were required to go through the hiring process for new police officers. Following successful completion of the process, officers were placed on an eligibility roster to await vacancies in the police department, and hired based on their rank on the roster. Rehired officers were required to reenter the force as entry-level officers in terms of pay, benefits, and seniority.
All of the appellants were subject to these regulations. Kevin Groesch was a police officer with the department for seven and a half years before resigning in 1988. When he later inquired about returning to the department, he was told he would have to go through the hiring process for new officers because his sixty day leave of absence had expired. After reapplying to the police department and awaiting reemployment from 1989 through 1996, Groesch was rehired by the department as an entry-level patrol officer in 1996. When Greg Shaffer resigned from the police department in 1987, he had worked there for seven years. He went through the rehiring process and returned to the department in 1993 as an entry-level officer, with no credit for his earlier years of service. Scott Allin resigned in 1986 after six years of service with the department. After six months away, he attempted to rejoin but was told he needed to reapply. Allin was eventually selected from the eligibility roster in 1989 and returned to work with no credit for his earlier years of service.
B. The “Schluter Ordinance’’ and State Court Litigation
The three appellants base their race discrimination claim on the different treatment of Officer Donald Schluter, an African-American officer who voluntarily resigned in November 1999 after five years with the department. When Schluter sought to return after a brief absence, he was not required to start over. The chief of police spoke with a city alderman, and on March 28, 2000, the Springfield City Council enacted the “Schluter Ordinance,” which specifically granted Officer Schluter a retroactive leave of absence to allow him to return with credit for his years of ser *1023 vice as an officer. The “whereas” clauses in the Schluter Ordinance listed a variety of reasons for the ordinance, including an interest in diversity in police ranks. After the ordinance was enacted, Officer Schluter returned to his position as a police officer without going through the formal hiring process, and he was hired at the same rate of pay he was earning when he resigned. 1
After the Schluter Ordinance was enacted, the local police union brought a lawsuit in state court against the City and Officer Schluter claiming it was unconstitutional, unreasonable, discriminatory, and an abuse of discretion. The state trial court found in favor of the union, and for a time the ordinance was invalidated. On appeal, however, the Illinois Appellate Court reversed and reinstated the ordinance, concluding that the union lacked standing.
The appellants then wrote to the chief of police requesting that the City give them equal treatment and credit them with their earlier years of service to the department, but their request was ignored. On April 3, 2003, the appellants filed a new state court lawsuit claiming disparate treatment under the equal protection clause in Article 1, Section 2 of the Illinois Constitution. The state court action was dismissed on statute of limitations grounds in a judgment entered on November 10, 2003, and that decision was affirmed by the Illinois Appellate Court on July 22, 2004.
C. District Court Proceedings
The appellants then filed this lawsuit in federal district court on July 27, 2004. In an order dated February 1, 2005, the district court denied the City’s motion to dismiss. The court relied in part on the “paycheck accrual” rule for determining timeliness of claims in pay discrimination. See
Hildebrandt v. Illinois Dept. of Natural Resources,
On May 29, 2007, however, the Supreme Court decided
Ledbetter v. Goodyear Tire & Rubber Co.,
II. The Ledbetter Decision and the Lilly Ledbetter Fair Pay Act of2009
The appellants argue that the Ledbetter Act requires that the judgment of the district court be reversed and that, because of the Ledbetter Act, the officers’ Title VII and equal protection claims are not barred as untimely. We agree, except with respect to the appellants’ claims for acts of discrimination before the state court judgment was entered on November 10, 2003, which we conclude are still barred by res judicata.
A. The Title VII Claims
The district court properly applied the Supreme Court’s decision in
Ledbetter
to grant summary judgment for the City on appellants’ Title VII claims. The facts of
Ledbetter
are now well known. Plaintiff Lilly Ledbetter claimed sex discrimination in pay in violation of Title VII and the Equal Pay Act of 1963, 29 U.S.C. § 206(d). She asserted that she had received negafive performance evaluations because of her sex and that her pay continued to be affected by those past performance reviews. See
Ledbetter,
Like Ms. Ledbetter, the appellants relied on the paycheck accrual rule to bring their claims. They argued that each time they received a paycheck, they received less than they would have received if they had been treated like Officer Schluter, the returning African-American police officer. Following Ledbetter, the district court had no choice but to dismiss the appellants’ Title VII claims.
Congress responded to the Ledbetter decision by enacting the Lilly Ledbetter Fair Pay Act of 2009, while this appeal was pending. The Act amends Title VII of the Civil Rights Act of 1964 by providing that the statute of limitations for filing an EEOC charge alleging pay discrimination resets with each paycheck affected by a discriminatory decision. More specifically, the Act provides that an “unlawful employment practice” occurs in the following situ *1025 ations: (1) “when a discriminatory compensation decision or other practice is adopted,” (2) “when an individual becomes subject to a discriminatory compensation decision or other practice,” and (3) “when an individual is affected by application of a discriminatory compensation decision or other practice, including each time wages, benefits, or other compensation is paid, resulting in whole or in part from such a decision or other practice.” 42 U.S.C. § 2000e-5(e)(3)(A).
Congress took the unusual step of expressly providing that the Ledbetter Act applies retroactively to all claims pending on May 28, 2007 or later. Pub.L. 111-2, § 6. The appellants’ Title VII claims are covered by the Ledbetter Act because they allege “discriminatory compensation decisions” and are based on the payment of wages resulting from those decisions.
The City has not offered any persuasive basis for avoiding application of the Lilly Ledbetter Fair Pay Act. First, the City argues that each paycheck the officers receive is determined by a “seniority pay system” and that a seniority pay system is a not a “discriminatory compensation decision or other practice” as contemplated by the Ledbetter Act. The problem is that the officers do not contend that the seniority pay system is inherently discriminatory, nor do they need to do so to satisfy the Ledbetter Act’s requirements. A facially neutral compensation system may still be applied in a discriminatory manner. That is why the Ledbetter Act requires only “a discriminatory compensation decision or other practice,” not an intrinsically discriminatory compensation system. It is enough to allege, as the officers do, that the City’s decisions as to who received prior service credit within the existing seniority system were motivated by race. The City’s seniority argument fails to come to grips with the fact that it changed the seniority system for Officer Schluter, and only for him. The City’s “neutral seniority system” argument attempts to sidestep both the language of the Act and the heart of the matter alleged by the appellants — that the City refused to recognize the white officers’ prior service under the seniority system while doing so for a black officer.
The City also relies on the first Supreme Court case to address the Ledbetter Act,
AT & T Corp. v. Hulteen,
— U.S. -,
Finally, the City seems to argue that this case can be distinguished from Ledbetter based on a supposed difference between race discrimination and sex discrim *1026 ination, or the factual differences between discriminatory performance evaluations and the policy choice reflected in the Schluter Ordinance. These arguments miss the point of both the Supreme Court’s broad rejection of the paycheck accrual rule in Ledbetter and the even broader legislative response in the Ledbetter Act. The district court’s grant of summary judgment on the Title VII claims after November 10, 2003 must be reversed. 3
B. The Equal Protection Claims under Section 1983
The appellants’ race discrimination claims under the Equal Protection Clause of the Fourteenth Amendment, brought under 42 U.S.C. § 1983, present some additional legal wrinkles. They filed those claims within the applicable two-year limit measured from the denial of their request for the same treatment that Officer Schluter received. But their equal protection claims were dismissed on res judicata grounds. In the absence of the paycheck accrual rule, the appellants each had only one discrimination cause of action that should have been asserted in their earlier and unsuccessful state court action.
Appellants argue, and we agree, that in the wake of the Ledbetter Act, they should be able to rely on the paycheck accrual rule to pursue their equal protection claims that arose after dismissal of the state court action. The paycheck accrual rule avoids the problem of res judicata because each paycheck reflecting the allegedly discriminatory decision gives rise to a distinct cause of action. We conclude that there is no principled reason for applying the paycheck accrual theory to claims arising under Title VII but not to those arising under 42 U.S.C. § 1983. As the district court concluded in denying the City’s motion to dismiss pre-Ledbetter, Hildebrandt and Reese, our cases applying the paycheck accrual rule in the Title VII context, extend logically to equal protection claims arising under Section 1983. If it was not already clear that Hildebrandt extended the paycheck accrual rule to pay discrimination claims under Section 1983, we hold here that paychecks reflecting a past discriminatory compensation practice create fresh causes of action under Section 1983, just as they do under Title VII after the Ledbetter Act.
The Supreme Court articulated what became known as the “paycheck accrual rule” in
Bazemore v. Friday,
In 2002, the Supreme Court decided
National Railroad Passenger Corp. v. Morgan,
Following
Morgan, Hildebrandt
and
Reese
firmly established in our circuit that under Title VII, a new cause of action for pay discrimination arose every time a plaintiff received a paycheck resulting from an earlier discriminatory compensation practice occurring outside the statute of limitations period. See
Reese,
The district court found that the appellants had filed timely Section 1983 claims, within the applicable two-year statute of limitations, but that, under
Ledbetter,
the equal protection claims were barred by res judicata because they could have been brought within the state court action. In fact, the
Ledbetter
decision focused specifically on Ms. Ledbetter’s Title VII claims and did not specify the applicability of its
*1028
holding to constitutional claims under Section 1983. But if
Ledbetter
was understood to extend logically to Section 1983 claims, as, for example, we had earlier understood
Morgan's
Title VII reasoning to extend to Section 1983 claims, see,
e.g., Evans v. City of Chicago,
Ledbetter and the Ledbetter Act leave some room for confusion as to the scope of the paycheck accrual rule. The Ledbetter decision explicitly applied only to Title VII claims, though its reasoning clearly would have extended to disparate pay claims under other employment discrimination statutes. The Ledbetter Act applies explicitly to claims under Title VII, but also to claims under the Americans with Disabilities Act, the Rehabilitation Act, and the Age Discrimination in Employment Act, none of which were specifically addressed by the Ledbetter Court. See Pub.L. No. 111-2. Neither the Ledbetter decision nor the Ledbetter Act addresses constitutional claims asserted under Section 1983. 4 In the absence of any clearer directive, we believe the best course is to treat the Ledbetter Act as removing the Ledbetter decision as an obstacle to following our earlier precedents, which recognized the paycheck accrual rule for all allegations of unlawful discrimination in employee compensation. We hold that the paycheck accrual rule applies to pay discrimination claims under Section 1983.
In a separate argument aimed at the equal protection claims, the City argues, contrary to the district court’s ruling, that the act of alleged discrimination occurred not when the white officers asked the chief of police for equal treatment but on March 29, 2000, when the City passed the Schluter Ordinance. On this theory, the City argues that the two-year statute of limitations period for appellants’ equal protection claims expired on March 29, 2002. The City argues that the Ledbetter Act “does not save otherwise untimely claims outside the discriminatory compensation context,” quoting
Richards v. Johnson &
*1029
Johnson, Inc.,
III. Preclusive Effect of State Court Decision
Finally, we consider whether the earlier state court litigation precludes further litigation of appellants’ claims even if they get the benefit of the paycheck accrual rule. “The doctrine of [res judicata or] claim preclusion is premised on the idea that, when a claim has been fully litigated and come to judgment on the merits, finality trumps.”
Czarniecki v. City of Chicago,
The City argues that the appellants’ later claims are also barred by res judicata even if the paycheck accrual rule applies. We disagree. As discussed above, following the Ledbetter Act, we recognize that each paycheck resulting from the original discriminatory act is a separate cause of action triggering its own statute of limitations. As the district court found, these independent causes of action do not share an “identity of cause of action” with the state court action. They are allegedly “wrongful events ... separated by time and function” from the allegedly discriminatory paychecks paid to the appellants before the state court case was decided.
Perkins v. Board of Trustees of University
*1030
of Illinois,
We should not be understood as opening the door to endless re-litigation of allegedly discriminatory decisions that affect compensation for many years. A critical point here is that the state court did not rule on the merits of the discrimination issue, but ruled only on statute of limitations grounds. Therefore, there is no collateral estoppel or issue preclusion problem that would prevent these plaintiffs from receiving a first decision on the merits of their discrimination claims. See id. (holding that the university’s prevailing in the first case on statute of limitations grounds did not mean that there was issue preclusion or collateral estoppel as to the plaintiffs later claims of new discrimination). The appellants may thus proceed with their discrimination claims for allegedly discriminatory compensation paid after November 10, 2003.
The appellants argue that the state court decision should have no preclusive effect at all on their Title VII claims because they had not yet received their EEOC “right-to-sue” letter, so the Title VII claim could not have been brought in their earlier state court suit. We rejected essentially the same argument in
Brzostowski v. Laidlaw Waste Sys., Inc.,
The judgment of the district court is Affirmed in Part, with respect to the dismissal of all claims arising before November 10, 2003 and with respect to Officer Shaffer’s claims for monetary damages before January 19, 2005. In all other respects the judgment is Reversed and the case is Remanded for proceedings consistent with this opinion.
Notes
. This opinion should not be interpreted as expressing any view on the ultimate merits of appellants’ race discrimination claims, including possible justifications for the Schluter Ordinance or differences between his situation and appellants' resignations and returns. We address only the statute of limitations and res judicata issues actually before us.
. Title VII claims must be filed within 180 or 300 days after the allegedly discriminatory act, depending on the state. In Illinois, the charging period is 300 days. See
Hall v. Bodine Elec. Co.,

Delaware State College
v.
Ricks,
. District courts have just begun to grapple with how broadly the Ledbetter Act should be construed. See,
