As one of the original Founding Partners of the Firm and as Managing Partner for almost 14 years, Atty. Dario acquired extensive law firm management and leadership experience. He has been multi-tasking both as to the Firm’s non-legal and legal aspects, from vision, policy and business directions setting, responsibility over the day-to-day operations of the administrative and financial concerns of the law firm, to actively managing, attending to or handling cases and other legal work either as the team leader, supervising or assisting lawyer.

Atty. Dario has almost 30 years of sustained exposure, since his admission to the Bar in 1985, to a wide-range of legal issues and concerns, as well as to the various regulatory framework environments and procedures involvingor covering the different governmental offices and agencies, commissions, boards, quasi-judicial tribunals and courts of law operating in the Philippines.

His litigation practice covers the investigative, prosecutorial, defense, appellate, conflict resolution/negotiation/settlement and execution/enforcement components, involving office-related malfeasance or misfeasance charges against corporate employees or officers and publicofficials, contractual, business/property disputes, land and environment matters, family-based and intra-corporate squabbles, tax deficiency assessment cases, employment standards and practices, including management-labor relations and disputes. In his three (3) decades of litigation experience, he has won 21 acquittals or the dismissal of 21 criminal cases involving clients of the Firm. He has personally conceived and led the implementation of action or operational plans, together with law enforcement authorities for the successful execution or enforcement of final court judgments, as well as retrieve, reinstate or recover the property and personal rights of the Firm’s clients. He has won landmark cases brought on appeal in the Supreme Court related to constitutional, procedural and property issues.

On the sidelines, he has either handled himself or assisted in work involving public development consultancy issues and questions. Upon his admission to the bar in 1985, Atty. Dario joined the law firm of Quiason, Makalintal, Barot, Torres & Ibarra whose Of Counsel was former Chief Justice of the Philippine Supreme Court, and later Speaker of the Batasang Pambansa (Philippine Parliament), Querube C. Makalintal.

One of this firm’s founding partners, Camilo D. Quiason himself was later appointed to and retired from the Supreme Court. While with the said law firm, Atty. Dario was entrusted with the more sensitive and controversial lawsuits in the country and on the side, attended to business law matters, as well as maintained a column on the law in the now defunct “Manila Chronicle” newspaper.

Atty. Dario then went on to assist and represent prominent political figures/ families in the numerous civil, criminal and tax evasion cases brought against them by the government following the 1986 People Power revolution before the Philippines’ Sandiganbayan (Philippine Anti-Graft Court), Ombudsman, Regional Trial Courts, Court of Appeals and Supreme Court. His balanced advocacy earned him in 1999, the endorsement by the three decades-old farmer’s group, the Federation of Land Reform Farmers [“FLRF”] to be its sectoral representative in the twenty-two (22)-man Preparatory Commission on Constitutional Reforms created by former President Joseph Estrada to study and recommend amendments to the provisions of the 1987 Constitution of the Philippines related to the economy.

Chaired by former Supreme Court Chief Justice Andres Narvasa, Jr. and co-chaired by former Prime Minister Cesar E.A. Virata, then Commissioner Dario was a member of the body’s committees on natural resources and land ownership and actively participated in the deliberations on trade liberalization, economic reforms and investments. A large part of the invaluable study made and report prepared by the commission has been adopted by the commission subsequently created in 2005 by former Philippine President Gloria Macapagal-Arroyo. With new calls for reforms in the economic-related provisions of the Constitution, the House of Representatives has since been invited Atty. Dario to be a resource person at the Committee level to discuss proposals for amendments to these provisions.

Atty. Dario was likewise identified in 2007 as a Resource Person and invited to participate in a discussion of the initial findings for the South East Asia Commercial Law and Institutional Reform – Trade Assessment (“SEA CLIR TRADE”) project study of the United States Agency for International Development [U.S.A.I.D.) in collaboration with the Virginia, U.S.A.-based consultancy group, Booz Allen Hamilton, as part of the USAID’s regional technical assistance in the region. No less than an active U.S. Federal Judge then as Lead Consultant visited and made a personal courtesy call on Atty. Dario at the Firm’s former offices in Pasig City.

He has completed his two-year term for the period 2005-2007 as a Director of the chapter for the four major Metropolitan Manila cities of Pasay, Las Piñas, Parañaque and Muntinlupa, of the Integrated Bar of the Philippines. He is also a founding trustee of the Muntinlupa Bar Association, the local working arm of the IBP for the City of Muntinlupa. He continues to be a member of the Philippine Constitution Association [“PHILCONSA”]. He is also active in ministry work in his Catholic Parish Church at the Ayala Alabang Village, Muntinlupa City.

His practice areas cover Criminal, Civil, Commercial, Banking, Corporate, Tax and Intellectual Property Litigation, including Appellate Practice and Special Projects.
