The anti-defection law is back in the spotlight, and this time it is because of Raghav Chadha.In a major political development, Chadha along with six other Rajya Sabha MPs has walked out of the Aam Aadmi Party and merged with the Bharatiya Janata Party, dealing a big blow to Arvind Kejriwal’s party. Chadha says the decision was driven by the belief that AAP had strayed from its core values and principles. But here is where it gets interesting.Despite switching sides, these MPs are unlikely to face disqualification. Why? Because of a key provision in the anti-defection law under the Tenth Schedule, the two-thirds rule. Since 7 out of AAP’s 10 Rajya Sabha MPs moved together, the law treats this not as defection, but as a valid merger.
