Mr Shullai verbally abused Mr Lanong on Wednesday evening when the latter refused to comply with his deputy's request to do something that was against the law. Mr Shullai even banged the table and threw the papers in the Speaker's chamber after being annoyed with the refusal of Mr Lanong.
The Deputy Speaker has, however, a different take on the incident. He claimed that it was the Assembly Speaker who misbehaved with him.
The matter was even brought to the notice of Chief Minister Dr Donkupar Roy. The Chief Minister asked NCP leader and Power Minister Conrad Sangma to settle the issue, since Mr Shullai belongs to NCP.
It was learnt that Mr Sangma met both Mr Lanong and Mr Shullai to pacify them. It seems the Power Minister has failed to convince the Speaker to resolve his differences with the Deputy Speaker as he (Mr Lanong) is reportedly taking this issue very seriously.
According to Mr Lanong, the incident took place when Mr Shullai came to his chamber asking him to do something that was against the law. As Mr Lanong refused to comply with the request of the Deputy Speaker, Mr Shullai started hurling abusive words at him in front of two female visitors.
"I (have) tried to tell Mr Shullai that we are the people who are responsible for making the laws and it would not be wise for us to do anything which is against the law," Mr Lanong told The Shillong Times.
The Speaker said Mr Shullai was trying to explain that former Assembly Speaker MM Danggo "used to entertain this kind of matters."
"I have made it clear that I am not Mr Danggo and my main goal of sitting in this chair is to clean up the whole system which affected the image of the State Assembly in the past," Mr Lanong said.
The Speaker alleged that Mr Shullai not only made abusive remarks to him but also tried to exert his power by banging on his table, adding he (Mr Lanong) did not react because he did not want to lower himself.
Mr Lanong said he would take up the matter with MPA leaders for "necessary action against this intolerable act of Mr Shullai."
Meanwhile, when contacted, Mr Shullai claimed that it was Mr Lanong who first misbehaved with him.
"Being the Deputy Speaker, I went to Mr Lanong's chamber to give my suggestions on some matter related to functioning of the Assembly. But the Assembly Speaker refused to listen to my suggestions," Mr Shullai said.
The Deputy Speaker alleged that the Speaker even threw the letter that he had given to him. Mr Shullai said he told Mr Lanong that he was also an MLA and he (the Speaker) should not misbehave with him
"After this, there was an exchange of words between me and Mr Lanong, but I never used any abusive remarks to him," Mr Shullai said.
Mr Shullai also claimed that Mr Lanong had on two occasions in the past thrown letters submitted to him by his supporters as well as supporters of Urban Affairs Minister Paul Lyngdoh.
Further, the Deputy Speaker alleged that Mr Lanong had never supported advertisement for the vacancies in the State Assembly.
"The Speaker filled the vacant posts on his own without the knowledge of the senior officials of the Assembly," Mr Shullai alleged.
