The Union government has set up a committee headed by President Ramnath Kovind to look at various aspects of implementing the ‘one nation, one election’ plan. The broad idea is to synchronise the timing of Lok Sabha and State Assembly elections across all States. The proposal for simultaneous elections has raised many concerns. Foremost among them is the impact it will have on federalism. Then there is the question of feasibility – what happens if a state government falls, for instance? Then there are the legal aspects – what are the various constitutional amendments that would be needed, and would the states have to ratify it as well?
