The Government of India has appointed a number of committees, a small group of officials appointed to deal with a particular parliamentary committees established by the Parliament of India.
The Parliamentary committees are established to study and deal with various matters that cannot be directly handled by the legislature due to their volume. The Parliamentary committees are of two kinds - Standing committees and Ad hoc committees. The former are elected or appointed periodically and they work on a continuous basis. The latter are created on an ad hoc basis as the need arises and they are dissolved after they complete the task assigned to them.
