On April 19, 1991, together with the Ministry of the Interior, the Ministry of Transportation and Communication, the Council of Agriculture, the Council of Labor Affairs, the Department of Health, and the Environmental Protection Administration of the Executive Yuan, the Ministry of Economic Affairs (foregoing seven administrative agencies referred to hereinafter as the Ministries) issued the Ministry of Economic Affairs Ordinance No. 015522 (80 Jin-Kung-Tze No. 015522) prescribing the “Practicing Areas of Engineers”, which limited the areas of practice of civil engineers to “the plan, design, research, and analysis of the structures of buildings whose heights are under thirty-six meters”. Such limitations are prescribed by the Ministries which are either the central governing authorities or the authorities in charge of relevant matters under the authorization of Article 22, Paragraph 2 of the Technician Act to allocate the areas of practice between civil engineers and structural engineers and are not in contravention to the constitutional guarantee of the right of work. In addition, on September 19, 1978 the Executive Yuan joined the Examination Yuan Ordinance No. 2414 (78 Tai-Mi-Yi-Tze No. 2414) of September 18, 1978 and issued the Executive Yuan Ordinance No. 8492 (78 Tai-Jin-Tze No. 8492) of September 19, 1978 stipulating “Categories of Engineers” and “Illustrations of Areas of Practice of Categories of Engineers”, which under the category of the structural engineer specially specified that, “until the numbers of practicing structural engineers reach an adequate level, practicing civil engineers and architects are temporarily authorized to be in charge of the structures of buildings.” This temporary authorization was a temporary measure adopted to reflect the then existing needs of the society and was abolished by the Executive Yuan and the Examination Yuan jointly on October 2, 1987. Later, the Ministries prescribed the above-mentioned “Practicing Areas of Engineers” and noted in the footnotes of the category of the civil engineer stating that, “those civil engineers who obtained their licenses before September 19, 1978 and had experiences of designing the structures of buildings above thirty-six meters before October 2, 1987 are not subject to the said limitation of buildings’ heights.” Accordingly, as a matter of course, those civil engineers who obtained their licenses after September 19, 1978 are subject to the said limitation of areas of practice.
