When the TBA was established in 1947, it had only 34 members. As of the end of 2010, the number exceeded 4,500, accounting for approximately 70% of all the lawyers in the nation, making it the local bar association with the most members.
The TBA was originally overseen by a director-general, and then tvotating managing directors. On 8 April 1990, the TBA became managed by a director-general in accordance with the Civil Associations Act. Twenty-one directors were then elected in accordance with the TBA's Articles of Association, seven of which were elected as managing directors with the President elected from among the seven managing directors by the 21 directors. In addition, the TBA has seven supervisors, with two acting as the standing supervisors.
To facilitate the association's development and enhance legal expertise, the TBA has set up dozens of standing committees and special field committees under the board of directors. Each committee consists of a chairman, vice chairman and several committee members who are all TBA members appointed by the board. The standing committees are each in charge of specific issues, for example, the Attorney Ethics and Discipline Committee handles member's disciplinary issues; the Justice Reform Committee is in charge of promoting and monitoring the national justice system and quality improvement; the Civil Legal Aid Committee plans and provides legal services to the disadvantaged minority communities; and the Legal Education Promotion Committee is dedicated to public legal education. On the subjects of national social-economic development and the development of the legal system, the special fields committees established committees to research and study the traditional fields including civil law, criminal law, commercial law and judicial practice and committees that promot social activism and research and study social issues such as women-rights issues, juvenile and children's problem studies, consumer debt clearance, and crime victim protection. Furthermore, there are also committees doing research and study of emerging fields such as competition law, life & technology law, sports & entertainment law, as well as non-litigious dispute resolution. (For the various standing committees and special field committees, please refer to Inserts.)
The TBA has a secretariat established under the board of directors, which comprises a secretary-general, several deputy secretary-generals, a general affairs officer, an accounting officer, a clerical officer, a PR officer and an information management officer. These officers are appointed by the board of directors from among the members and hold the part-time positions without pay, to oversee the execution of the day-to-day affairs of the association by full-time employees. The secretariat also has an executive secretary and five working sections with full-time staff to handle association affairs including clerical affairs, general affairs, accounting, information management and PR. Each section has a section chief and a number of secretaries, specialists and assistants.
