The story so far:

The Model Code of Conduct (MCC), which guides political parties and candidates during elections, was first drafted by the Kerala government in 1960. The Election Commission (EC) formalised it in 1968, revised it in 1974, and added Part VII on the “party in power” in 1979. Former Chief Election Commissioner T.N. Seshan enforced it with unprecedented rigour from 1991. Prime Minister Narendra Modi’s April 18 address has raised questions about whether the address violated the Code.
