Can the government levy and collect other taxes or duties not mentioned in the Constitution?
Yes, the government can levy and collect other taxes or duties not mentioned in the Constitution, as long as they are authorized by a law passed by the Parliament. The context provided does not limit the government's ability to create new taxes or duties, only stating that certain specific stamp duties are levied by the Government of India but collected by either the Union Territories or the States depending on where they are leviable.
