Congress president Sonia Gandhi today asked states ruled by her party to consider bringing laws to overrule the centre's farm laws, which have provoked massive farmer protests in parts of the country. "Hon'ble Congress President has asked the Congress-ruled states to explore the possibilities to pass laws in their states under Article 254(2) of the constitution which allows the state legislatures to pass a law to override a Central law which then comes for President Assent (sic)," senior Congress leader KC Venugopal tweeted.
