Equal Protection Evolved When Subsequent Laws Invalidate Prior Statutes

The Constitution guarantees that no person shall be denied the equal protection of the laws. But what happens when a law, valid when enacted, becomes unconstitutional because of later laws that treat similarly situated persons differently? In Central Bank (now Bangko Sentral ng Pilipinas) Employees Association, Inc. v. Bangko Sentral ng Pilipinas (G.R. No. 148208, December 15, 2004), the Supreme Court En Banc confronted exactly this question and laid down an important doctrine: a statute may be valid on its face and at the time of its enactment, yet become void in its continued operation when changed circumstances—including the passage of subsequent laws—render its application invidious discrimination.

The Facts

Republic Act No. 7653, the New Central Bank Act, took effect on July 3, 1993. It abolished the old Central Bank and created the Bangko Sentral ng Pilipinas (BSP). Section 15(c), Article II of the law directed the Monetary Board to establish a compensation structure for BSP personnel. The last proviso of that section, however, provided that employees whose positions fall under Salary Grade 19 and below shall receive compensation in accordance with the rates prescribed under Republic Act No. 6758, the Salary Standardization Law (SSL).

In 2001, the Central Bank (now BSP) Employees Association filed a petition for prohibition. The association argued that the proviso created an unconstitutional classification between BSP officers (Salary Grade 20 and above, exempt from the SSL) and rank-and-file employees (Salary Grade 19 and below, covered by the SSL). It also pointed out that after R.A. 7653 was enacted, Congress amended the charters of seven other government financial institutions (GFIs)—the Land Bank of the Philippines, Social Security System, Small Business Guarantee and Finance Corporation, Government Service Insurance System, Development Bank of the Philippines, Home Guaranty Corporation, and Philippine Deposit Insurance Corporation—and exempted all their employees, without distinction as to salary grade, from the SSL.

The Issue

The sole issue was whether the last proviso of Section 15(c), Article II of R.A. 7653 violated the equal protection clause of the Constitution.

The Ruling

The Supreme Court first acknowledged that, under traditional equal protection standards, the classification between BSP officers and rank-and-file employees was valid. The exemption of officers from the SSL was intended to address the BSP's lack of competitiveness in attracting competent officers and executives. This distinction had a rational basis and was not arbitrary.

However, the Court then applied a deeper level of scrutiny. It noted that the constitutionality of a statute cannot always be determined by a mere comparison of its provisions with the Constitution. A statute valid at one time may become void at another time because of altered circumstances. If a statute in its practical operation becomes arbitrary or confiscatory, its validity is open to inquiry in light of changed conditions.

The Court took judicial notice that from 1995 to 2004, Congress amended the charters of seven other GFIs and granted each of them a blanket exemption from the SSL for all their employees—expressly or impliedly. Even the Securities and Exchange Commission was granted the same exemption in 2000. This meant that eleven years after the BSP charter was amended, the rank-and-file of seven other GFIs received the exemption that was specifically denied to the BSP rank-and-file.

The Court found no substantial distinctions that would differentiate the BSP rank-and-file from the rank-and-file of the other GFIs. Under R.A. 6758, the rank-and-file of all GFIs were similarly situated in all aspects pertaining to compensation and position classification. The subsequent enactments constituted significant changes in circumstance that altered the reasonableness of the continued operation of the challenged proviso. The proviso may have been fair on its face, but it could not be grossly discriminatory in its operation.

The Court rejected the argument that each exemption rested on a policy determination by Congress. All legislative enactments rest on policy determinations, but such determinations cannot run riot and overrun the ramparts of constitutional protection. The guarantee of equal protection includes the prohibition against enacting laws that allow invidious discrimination, directly or indirectly. If a law has the effect of denying equal protection, or permits such denial, it is unconstitutional.

The Court declared that the continued operation of the last proviso of Section 15(c), Article II of R.A. 7653 constituted invidious discrimination against the 2,994 rank-and-file employees of the BSP.

Practical Takeaways

• A statute that is valid when enacted may later become unconstitutional if changed circumstances—including the passage of subsequent laws—make its continued application discriminatory.
• Equal protection analysis is not confined to the four corners of a single statute. Courts may consider how a law operates in relation to other laws affecting similarly situated persons.
• A classification that is reasonable at one point in time may become unreasonable when the legislature treats a broader class inconsistently over time.
• Government financial institutions and their employees have long been recognized as a distinct class under Philippine law, and distinctions within that class must be justified by substantial differences.
• For employees and employers alike, the lesson is that legislative changes affecting comparable institutions can alter the constitutional validity of existing compensation schemes.
