At this juncture Modi & BJP saw an opportunity to gain foothold in Tamilnadu, with just 2.86% vote share and lost all 232 seats contested in 2016 elections. Governor, Ch.Vidyasagar Rao (a BJP leader) indicated that in the interest of forming a stable government, he would wait for SC judgement, in a DA case against Jayalalitha, Sasikala, Elavarasi & Sudhakaran, and had traveled from Delhi to Mumbai instead of to Chennai. Governor's action of not inviting majority party leader to form government, on some pretext or other, is fundamentally incorrect, unprecedented, irrational and blatantly unconstitutional & illegal as there is no bar on a person holding constitutional positions until convicted and jailed. Presumptive action by Governor is in violation of fundamental principles of democracy is untenable and despicable. At the same time the outgoing CM O.Paneer Selvam changed his mind and revolted against Sasikala charging her with applying pressure to sign resignation and requested Governor to permit him withdraw the resignation which was already accepted and is unmaintainable. On Feb 14, 2016 SC delivered judgement upholding Trial Court's conviction judgement in toto, setting aside HC's acquittal judgement, and Governor's stand seems to be vindicated but still is unconstitutional and amounts to overreaching his powers.
Thus, Modi is once again is at receiving end in Tamilnadu, after his failed adventures in Bihar, Uttarakhand and Arunachal Pradesh, in the past denting his already spoiled image further badly.
Modi and BJP's game plan to gain foot hold in every state without winning hearts of the people by sheer manipulations is totally against the principles of democracy and making mockery of governance. With Sasikala in jail, and thin majority of 124 against 117, how long K.Palani Swamy government will survive is a million dollar question. A switch by 10 MLAs will pull down the government for which DMK, BJP and Congress would be anxious to do at the earliest opportunity. If that happens, most likely it will in next few months, midterm poll becomes inevitable and DMK & Stalin would be in a position of advantage.
Sensing the reality, the parties behind Paneerselvam namely BJP, DMK & Congress distanced themselves and are trying to be neutral in the forthcoming floor test of new CM Palaniswamy and allowing Paneerselvam to get isolated.
