Section 27, Article II of the 1987 Constitution provides that it shall be the policy of the State to maintain honesty and itegrity in the public service and take positive and effective measures against graft and corruption. Pursuant to this mandate and in the common aspiration and proactive collaboration to build a culture of integrity, transparency and accountable governance and ensure the highest standards of ethics and excellence in government, the three (3) constitutional offices namely : the Civil Service Commission, Commission on Audit and the Office of the Ombudsman convened an Anti-Corruption Summit on January 28-29, 2004 at Dive Solana, Anilao Batangas. The outputs of the said Summit were: a) an assessment of the three (3) constitutional offices respective institutions, anti-corruption mandates, specific mission and strategic objectives, resources and accomplishments; b) and concrete and doable initiatives which shall be undertaken jointly and by each institution within the next five (5) years.
Consequently, the three (3) constitutional offices forged a Joint Anti-Corruption Plan called the "SOLANA Covenant" on March 16, 2004. It was followed by the forging of the SOLANA II: the 2nd Anti- Corruption Summit of Independent Accountability Institutions on July 15, 2005, to improve the strategies of the first action plan as well as initiate new commitments towards the realization of common goals.
However, from 2005 up to this 2009, no other Anti-Corruption Summit or new covenant was forged by the three (3) constitutional offices who likewise share the same vision of eradicating graft and corruption. As such it was only appropriate and timely to reactivate the SOLANA; on December 18, 2009 the three (3) constitutional offices entered into a Memorandum of Agreement for that noble purpose and named themselves as the CONSTITUTIONAL INTEGRITY GROUP (CIG). This enables the respective agencies to assess and review strategies and accomplishments in the SOLANA Covenants I and II as well as initiate, plan and propose new commitments and initiatives.
