Every ordinance issued by the President during the recess of the Parliament must be laid before both the houses when it reassembles. They must be enacted into legislation within 6 weeks after Parliament comes back to the session or else they cease to operate on the expiry of 6 weeks. Hence, the maximum life of an ordinance is 6 months and 6 weeks (six months being the maximum gap between the two sessions of parliament). Therefore for a permanent effect, a legislation needs to be passed by the Parliament.
