The 1988 Malaysian constitutional crisis (also known as the 1988 judicial crisis) was a series of events that began with United Malays National Organisation (UMNO) party elections in 1987 and ended with the suspension and the eventual removal of the Lord President of the Supreme Court, Tun Salleh Abas, from his seat. The Supreme Court in the years leading up to 1988 had been increasingly independent of the other branches of the government. Matters then came to a head when Mahathir Mohamad, who believed in the supremacy of the executive and legislative branches, became Prime Minister. Many saw his eventual sacking of Salleh Abas and two other Supreme Court judges as the end of judicial independence in Malaysia.
