The palace intrigue currently going on in Uttar Pradesh is a hallmark of despotic monarchies. A father and son struggling for power, with attendant uncles, cousins, nephews, wives and daughters ranging themselves either with the patriarch or the scion seems like something straight out of the Mahabharata. It isn't even entirely unprecedented in contemporary India.
HD Kumaraswamy defied his father HD Deve Gowda to extend support to the BJP after breaking an alliance with the Congress to become the chief minister of Karnataka in 2006. The fall of the Congress-JDS alliance and the swearing-in of the BJP-JDS in Karnataka did not involve the imposition of President's Rule. As morally dubious as Kumaraswamy and JDS’ actions were, they didn't necessarily cause a constitutional crisis.
The present situation in Uttar Pradesh, where the Samajwadi Party enjoys a simple majority in the Vidhan Sabha, could still result in a constitutional crisis in one of two possible ways. Depending on who strikes first, Mulayam or Akhilesh, we could see different scenarios playing out.
