"I declare that Hitendra Nath Goswami is elected as Speaker of the House unanimously," Assam Assembly Deputy Speaker Dilip Kumar Paul said.
The process was necessitated due to former Speaker Ranjeet Kumar Dass resigning from the post after becoming the president of BJP's Assam unit last month.
Goswami received seven nominations in support of him.
After election, he said from the Chair, "I will work independently for upholding democratic values. My aim will not be to adjourn the House during differences. I will use the elasticity and discretion power of the Chair in such moments."
