The Constitution of India came into effect.
== Etymology ==The term constitution comes through French from the Latin word constitutio, used for regulations and orders, such as the imperial enactments (constitutiones principis: edicta, mandata, decreta, rescripta)
 However, the presence of statutes with constitutional significance, namely the Statute of Westminster, as adopted by the Commonwealth in the Statute of Westminster Adoption Act 1942, and the Australia Act 1986 means that Australia's constitution is not contained in a single constitutional document
