The rulings of the Constitutional Court of Thailand have, since the Court's establishment in 1998, had an important impact on Thai politics and jurisprudence. Major rulings having included the 1999 ruling that Deputy Minister of Agriculture Newin Chidchop could retain his Cabinet seat after being sentenced to imprisonment for defamation, the 2001 acquittal of Thaksin Shinawatra for filing an incomplete statement with the National Counter-Corruption Committee, the 2003 invalidation of Jaruvan Maintaka appointment as Auditor-General, and the 2006 invalidation of the nationwide results of a House election.
In its very first decision, the Court ruled on the constitutionality of four emergency executive decrees issued by the Chuan government to deal with the Asian financial crisis. The government had issued the decrees in early May 1998 to expand the role of the Financial Restructuring Authority and the Assets Management Corporation, to settle the debts of the Financial Institutions Development Fund through the issue of 500 billion THB in bonds, and to authorize the Ministry of Finance to seek 200 billion THB in overseas loans. The opposition New Aspiration Party (NAP) did not have the votes to defeat the bills, and therefore, on the last day of debate, invoked Article 219 of the Constitution to question the constitutionality of an emergency decree.
The NAP argued that since there was no emergency nor necessary urgency (under Article 218(2)), the government could not issue any emergency decrees. Article 219, however, specifically notes the constitutionality of an emergency decree can be questioned only on Article 218(1) concerning the maintenance of national or public safety, national economic security, or to avert public calamity. The government, fearing further economic damage if the decree were delayed, opposed the Court's acceptance of the complaint, as the opposition clearly had failed to cite the proper constitutional clause. The Court wished to set a precedent, however, demonstrating it would accept petitions under Article 219, even if technically inaccurate. Within a day it ruled that it was obvious to the general public that the nation was in an economic crisis, and that the decrees were designed to assist with national economic security in accordance with Article 218(1). The decrees were later quickly approved by Parliament.
