Maharashtra assembly speaker Rahul Narwekar on Tuesday said that he needs to ascertain which development is to be treated as "unconstitutional", in reference to the pleas before him seeking disqualification of rebel Shiv Sena MLAs.

The delay in deciding the disqualification petitions against Maharashtra Chief Minister Eknath Shinde and Shiv Sena MLAs loyal to him has come under strict scrutiny by the Supreme Court which on Friday came down hard on the state assembly speaker, saying the proceedings cannot be a charade and he cannot "defeat" its orders, the PTI reported.
