The Sri Lankan Constitution of 1972 was a constitution of Sri Lanka, replaced by the 1978 constitution currently in force. It was Sri Lanka's first republican constitution, and its second since independence in 1948. The constitution changed the country's name from Ceylon to Sri Lanka, and established it as an independent republic.[1][2][3][4][5] The country was officially designated as the "Republic of Sri Lanka," leading to the constitution being known as the 1972 Republican Constitution. The constitution was promulgated on 22 May 1972.[1]
