Ordinances are temporary laws that are promulgated by the President of India on the recommendation of the Union Cabinet. They can only be issued when Parliament is not in session. They enable the Indian government to take immediate legislative action. Ordinances cease to operate either if Parliament does not approve of them within six weeks of reassembly, or if disapproving resolutions are passed by both Houses. It is also mandatory for a session of Parliament to be held within six months of passing an ordinance.
