The Commission's strongly-worded instructions came against the backdrop of politicians using election rallies and press conferences to target each other viciously ahead of the crucial assembly elections.
The EC said it has observed "with a deep sense of anguish and serious concern about the plummeting levels of political speeches by various political party leaders and candidates in the ongoing general election to the Bihar Legislative Assembly".
"The tone and tenor of the political speeches have been found to be calculated to cause mutual hatred, disharmony or ill-will and aimed at to aggravate the differences between different political parties and classes of citizens on the grounds of religion, caste and community which the Model Code of Conduct dissuades the political parties and candidates."
The Commission reminded politicians that the fundamental right of freedom of speech and expression is not absolute and is required to be exercised in such a manner that it does not transcend the boundaries of decency and morality or disturb public order or amount to defamation or give incitement to an offence.
FIRs have been already lodged aginst RJD chief Lalu Prasad for his "narbhakshi" (cannibal) comment against BJP chief Amit Shah. Shah has also been booked for his "chara chor" (fodder thief) barb against Prasad
Prasad was also locked in a slugest with Prime Minister Narendra Modi over the former's 'Hindus also eat beef' remark.
"I wonder the devil got only his (Lalu) body to enter. I want to know how the shaitan got the address (of Lalu). The devil got no other body in entire Bihar, India and the whole world except that of his. And he also welcomed the devil as if some relative has come," Modi said.
In a sharp retort today, Prasad called Modi a "Brahma Pishach" (super demon).
"If I am a 'shaitan', he is a 'Brahma Pishach' (powerful demon spirit as described in ancient Hindu texts)," he said.
Hitting back, JD(U) leader Nitish Kumar said BJP means 'Badka Jhutha Party' (party of big liars) and 'Bhartiya Jumla (platitude) Party'.
