Explanation:

What is a Model Code of Conduct?
The Model Code of Conduct (MCC) is a document from the Election Commission of India.It lays down the minimum standards of behaviour for political parties and their candidates contesting elections.
When did it come about?
The MCC was first proposed by Kerala in its 1960 assembly elections.It was later adopted by the Election Commission of India (EC) during mid-term elections in 1968 and 1969.
Is it legally binding?
The Model Code of Conduct does not have any statutory backing.But the Code has come to acquire significance in the past decade, because of its strict enforcement by the EC.Some of the more serious offences listed in the Code have also found their way into the statute books.So for some of the offences mentioned, candidates can be tried under the Indian Penal Code or the Representation of the People Act 1951.
