ABA Presidency
The over-arching theme of Mr. Greco’s ABA presidency was renaissance – a reaffirmation of the legal profession's core values and America's constitutional principles. His priorities included protecting constitutional rights of Americans, safeguarding the independence of the judiciary, advancing the rule of law and human rights in the US and abroad, providing for the legal needs of the poor, and advancement of women, people of color and persons with disabilities in the legal profession. During his term of office he appointed two ABA Commissions, five ABA Task Forces and several Special Committees to implement his presidential initiatives and address issues of concern to the public and the legal profession.

His ABA Commission on Civic Education and the Separation of Powers, led by honorary co-chairs US Supreme Court Associate Justice Sandra Day O’Connor and former US Senator Bill Bradley, and chair Robert H. Rawson, addressed the troubling but reliably documented fact that half of Americans do not know the basics about their constitutional democracy due to lack of adequate civics education and therefore are not knowledgeable enough to protect the institutions of their democracy, particularly an independent judiciary. The Commission worked for two years and had significant influence on a number of state school systems and legislative enactments that reintroduced the teaching of civics in the schools. The ABA continues its efforts to improve civics education in the nation’s school systems and to protect the independence of the judiciary.

In concert with the important civics education efforts of the ABA Commission on Civic Education and the Separation of Powers, Mr. Greco selected as the theme of Law Day 2006 “Liberty under Law – Separate Branches, Balanced Powers.” Hundreds of Law Day programs for young and adult Americans were conducted in communities and schools across the country to underscore the importance of the separation of powers in our democratic form of government and to remind all that democracy will not survive without a knowledgeable public that zealously protects it.

He also appointed the ABA Task Force on Hurricane Katrina as that hurricane was still raging in order that lawyers across America could provide free legal services to all victims of Katrina and other hurricanes that devastated the Gulf States in the fall of 2005. The Task Force coordinated an unprecedented effort by thousands of lawyers to provide desperately needed free legal services to many thousands of hurricane victims.

During his ABA presidency Mr. Greco also appointed two bi-partisan, blue-ribbon task forces – the ABA Task Force on Domestic Surveillance in the Fight against Terrorism, and the ABA Task Force on Presidential Signing Statements and the Separation of Powers Doctrine – both comprised of distinguished constitutional scholars and former government leaders and judges, to protect Americans' constitutional rights, the doctrines of separation of powers and checks and balances, and America's democratic form of government.

The Task Force on Domestic Surveillance carefully considered the US government's program of spying on American citizens and issued a unanimous report and unanimous recommendations urging the President to respect the roles of Congress and the Judiciary, and to comply with the Constitution and existing federal laws, and urged immediate corrective action by Congress and the Courts. The ABA House of Delegates at its February 2006 Midyear Meeting in Chicago adopted the bi-partisan Task Force's recommendations by a near-unanimous vote.

The Task Force on Presidential Signing Statements considered the use, and misuse, by a President of “signing statements” that indicate a President’s intention, despite signing them, not to enforce parts of new laws enacted by Congress. The bi-partisan Task Force issued a unanimous report and recommendation concluding that such misuse by a President of signing statements violates the Constitution, encroaches unlawfully on the powers of Congress, and poses a threat to the separation of powers doctrine and the system of checks and balances that have sustained our democracy for more than two centuries. The Task Force urged legislative action by Congress and judicial review by the Supreme Court of the United States to resolve the constitutional issues presented. At the August 2006 Annual Meeting in Honolulu the ABA House of Delegates adopted the Task Force's recommendations by an overwhelming vote.

During his presidency Mr. Greco also encouraged and co-sponsored two unprecedented diversity conferences, one organized by the ABA Commission on Racial and Ethnic Diversity and other partners that addressed the imperative of ensuring the flow of young people of color in the pipeline to the legal profession, and the other organized by the ABA Commission on Mental and Physical Disability Law and other partners that addressed the employment needs of lawyers with physical and mental disabilities.

He also supported efforts of the ABA Commission on Women in the Profession to ensure the continued advancement of women in the legal profession, particularly women of color whose discrimination and professional plight was documented in a several years-long survey and final report released at the Association's August 2006 Annual Meeting in Honolulu.

He also directed the ABA Commission on Immigration Law to develop new Association policies to help address the situation of America's twelve million undocumented immigrants. As stated by Congressional leaders, the Commission's report and recommendations, which were overwhelmingly approved by the House of Delegates at the February Midyear Meeting, helped Congress craft appropriate legislation.

Mr. Greco also created, and appointed the boards of directors of, three new ABA legal centers. The ABA Resource Center for Access to Justice Initiatives was created to assist efforts throughout the United States to improve ways by which legal services are delivered to our nation's poor, and to help implement a civil right to counsel, or "Civil Gideon." The ABA Center for Racial and Ethnic Diversity consolidated and coordinated the Association's many diversity programs. The ABA Center for Rule of Law Initiatives consolidated and enhanced the Association's growing and increasingly important international rule of law programs in Africa, Asia, Central Europe/Eurasia, and Latin America, which provide legal technical assistance and training to emerging democracies in more than forty countries on five continents, including former republics of the Soviet Union.

In his effort to unify the legal profession throughout the world to advance and protect the rule of the law and human rights in all nations, at a Paris conference of one hundred world bar leaders in November 2005 he authored and thereafter advocated the adoption and ratification of a Statement of Core Principles of the legal profession. The Statement was adopted unanimously by the world bar leaders meeting in Paris and by the ABA House of Delegates at its Midyear Meeting in February 2006, and since then has been adopted by many bars throughout the world.

During his term as ABA president Mr. Greco initiated, negotiated and executed on behalf of the Association “Memoranda of Understanding” or collaboration agreements between the ABA and the national bars of China, Russia and Japan in order to provide for mutually beneficial exchanges of lawyers, legal knowledge and expertise, to conduct joint legal education programs, and to advance justice and the rule of law in those nations. He has represented the ABA and the US legal profession in substantive meetings with leaders in some thirty countries, and has traveled to meet with lawyers and judges and government leaders in forty-seven states, Puerto Rico and the District of Columbia.

Following his ABA presidency Mr. Greco continues to be invited to address and meet with government officials, Supreme Court justices and leaders of the bar both in the United States and abroad on issues such as regulating lawyers in a global economy, advancement of the rule of law internationally, protection of human rights, elimination of corruption in justice systems, and access to justice for all. His recent addresses include those in Kosovo, El Salvador, Brazil, England, Austria, Spain and Canada, and he has met in the United States with high government officials and Supreme Court justices from Indonesia, Vietnam and China, among other countries.
