Case digest · Reclaimed land in a BOT project; when it becomes alienable and patrimonial; the right to information

Chavez vs. National Housing Authority

Smokey Mountain was a garbage dump in Balut, Tondo, where many Filipinos lived. To pay for housing there, the sea across Radial Road 10 was reclaimed, and the new land went to the builder as its share. Almost a year after the project ended, Francisco I. Chavez asked the Supreme Court to declare it void, citing his own win against PEA.

Facts

The place

Smokey Mountain was a dumpsite in Balut, Tondo, Manila, bounded on the west by Radial Road 10 (R-10). The Court described it as a wasteland “where numerous Filipinos resided in subhuman conditions, collecting items that may have some monetary value from the garbage.”

1988–1992

Pursuant to a memorandum order of President Corazon C. Aquino, the National Housing Authority (NHA) prepared the studies that led to the Smokey Mountain Development and Reclamation Project, which aimed to convert the dumpsite into a housing project, with the reclamation of the area across R-10 as its enabling component. The Build-Operate-and-Transfer (BOT) Law, enacted on July 9, 1990, allowed a reclamation contractor to be repaid with a portion or percentage of the reclaimed land, subject to the constitutional requirements on the ownership of lands. On January 17, 1992, President Aquino approved the project in Memorandum Order No. 415, which conveyed to the NHA the dumpsite and the area to be reclaimed across R-10.

1992–1993

On August 31, 1992, a technical committee recommended the proposal of R-II Builders, Inc. (RBI), which had the highest score, and RBI became the NHA’s joint venture partner after public bidding. President Ramos’s Proclamation No. 39 placed the dumpsite and the area to be reclaimed under the administration and disposition of the NHA. On March 19, 1993, the NHA and RBI signed a Joint Venture Agreement: RBI would fully finance the project, build 3,500 permanent housing units on the leveled Smokey Mountain, and receive the reclaimed land as its asset share.

1994–1996

Amendments raised RBI’s share from 40 to 79 hectares of reclaimed land, and Proclamation No. 465 enlarged the area to be reclaimed. The DENR issued special patents in favor of the NHA, and the reclamation was completed in August 1996. Lots from the reclaimed land were later sold to private corporations, and titles were issued to the buyers.

2003–2004

On August 27, 2003, the NHA and RBI agreed in a Memorandum of Agreement to terminate the joint venture and the later agreements. On August 5, 2004, former Solicitor General Francisco I. Chavez, as a taxpayer, filed a petition for prohibition and mandamus in the Supreme Court, raising constitutional issues and citing Chavez vs. PEA.

Issue

Does Chavez vs. PEA control, and could the reclaimed land across R-10 be validly transferred to RBI, a private corporation? May the NHA be compelled to disclose the project’s records?

Ruling

The Court partially granted the petition. It denied the prayer for a writ of prohibition, holding the project’s agreements “valid, legal, and constitutional”, and granted the prayer for a writ of mandamus, ordering the NHA to give Chavez access to the project’s records.

Chavez had standing as a taxpayer, but the Court found Chavez vs. PEA “not a binding precedent” here, because the facts were substantially different. It listed seven differences, among them that the NHA reclaimed the land with the approval of two Presidents, that RBI was chosen after public bidding, that the agreements were a BOT contract, and that the land went to the NHA, an agency not tasked to dispose of public land. It still resolved every issue. PEA’s power to reclaim is not exclusive, and the DENR was deemed to have granted the authority to reclaim. The Court admitted that MO 415 and Proclamations Nos. 39 and 465 are not explicit declarations that the land is alienable and disposable, but found that conclusion derived and implicit from the authority given to the NHA to transfer the land, and held that the special patents classified the reclaimed areas as alienable and disposable. The land became alienable when the special patents were issued and patrimonial when the titles were issued to the NHA. The presidential proclamations and the special patents removed it from public use, and its conveyance to the contractor under the BOT Law implied that it was no longer intended for public use. As patrimonial property, it could be transferred without public bidding to RBI, a corporation in which Filipino citizens own at least 60% of the stock. The PEA ruling could not be applied retroactively, since the reclamation was completed in August 1996; the respondents were in good faith; and the titles of the buyers can no longer be invalidated. Prohibition did not lie, since administrative remedies were not exhausted and the project was a fait accompli; the Court added that Chavez was the Solicitor General when the project was formulated and implemented, and had not questioned it then. On the right to information, the Court treated the petition as a written request and ordered the NHA to allow access to the records. As to Phase II of the project, the Court noted that it had been struck down by the Clean Air Act. The decision was unanimous; Carpio and Reyes, JJ., took no part.

“The lands become alienable and disposable lands of public domain upon issuance of the special patents and become patrimonial properties of the Government from the time the titles are issued to the NHA.”
Chavez vs. National Housing Authority, G.R. No. 164527, August 15, 2007

Doctrine

The Court conceded that the presidential acts were not explicit: “Admittedly, it cannot be said that MO 415, Proclamations Nos. 39 and 465 are explicit declarations that the lands to be reclaimed are classified as alienable and disposable. We find however that such conclusion is derived and implicit from the authority given to the NHA to transfer the reclaimed lands to qualified beneficiaries.” It also read the classification into the BOT Law: “reclaimed lands that are made the enabling components of a BOT infrastructure project are necessarily reclassified as alienable and disposable lands under the BOT Law; otherwise, absurd and illogical consequences would naturally result.” On the right to information, the petition itself served as the demand: “We find that although petitioner did not make any demand on the NHA to allow access to information, we treat the petition as a written request or demand.”

Compare: still public in PEA’s hands

In Chavez vs. Public Estates Authority, G.R. No. 133250, July 9, 2002, the reclaimed land was held by PEA, an agency tasked to dispose of public lands, and the Court held that “The alienable lands of the public domain must be transferred to qualified private parties, or to government entities not tasked to dispose of public lands, before these lands can become private or patrimonial lands.” In a footnote, the NHA Court added: “Thus, the July 9, 2002 Decision is still the valid case law.”

Bar tip

Read Chavez vs. NHA on its facts, not as permission for any corporation to buy reclaimed land. The Court relied on presidential acts and special patents classifying the land, a BOT contract, titles issued to the NHA, an agency not tasked to dispose of public land, and a transferee (RBI, the BOT contractor) at least 60% owned by Filipinos. It distinguished Chavez vs. PEA; it did not overrule it.
