Bangladesh 1975
The 1975 decision to amend Bangladesh's 1972 constitution took place during a period of floods, famine, and inflation. Other political parties had accused the Awami League, the Prime Minister's political party, of being ineffectual. The Prime Minister declared a “State of Emergency” Decree of December 28th that suspended rights under the constitution and suspended the normal parliamentary rules. He and his closest allies drafted an amendment to change the parliamentary government into a presidential system and to create a single party state.
Because normal parliamentary rules were suspended, there was no discussion period about the amendment before the legislature was required to vote. IThe proposed changes came from the prime minister's office in a single bill without possibility of amendment by legislators. Although some members protested, the Awami League held 293 of the 300 votes in parliament, and the amendment passed by the required 2/3 majority. It went into force on January 25, 1975.
NOTE: A coup on August 15, 1975 placed the country under Martial Law. President Sheik Mujib was assassinated.
