Voting and Language in State Legislature

Voting in House
All matters at any sitting of either House are decided by a majority of votes of the members present and voting excluding the presiding officer. Only a few matters which are specifically mentioned in the Constitution like removal of the speaker of the assembly, removal of the Chairman of the council and so on require special majority, not ordinary majority. The presiding officer (i.e., Speaker in the case of assembly or chairman in the case of council or the person acting as such) does not vote in the first instance, but exercises a casting vote in the case of an equality of votes.
Language in State Legislature
The Constitution has declared the official language(s) of the state or Hindi or English, to be the languages for transacting business in the state legislature. However, the presiding officer can permit a member to address the House in his mother-tongue. The state legislature is authorised to decide whether to continue or discontinue English as a floor language after the completion of fifteen years from the commencement of the Constitution (i.e., from 1965). In case of Himachal Pradesh, Manipur, Meghalaya and Tripura, this time limit is twenty-five years and that of Arunachal Pradesh, Goa and Mizoram, it is forty years.
